What not to do as a new home owner

Becoming a new home owner is a very exciting time. There are plenty of new tasks to take on after obtaining the keys. However, there are some things a new home owner should NOT do after moving in.
1. Not being familiar with the new home
There are parts of a new home that the new owner should be aware of. The main water valve and circuit box are two crucial components of a home. Locating these two items is very important as a home owner. In case of an emergency such as a burst pipe, there may be no time for scrambling to find the circuit box or water valve. In addition, it is good practice to label it, so it is clear which fuses belong to each room.
2. Not paying attention to the foundation
The foundation is arguably the most important aspect of a home. Something as simple as the slope of soil around the foundation can be indicative of big problems. If the soil does not slope six inches over ten feet, water from snow and rain can seep into the foundation causing cracks and leaks. This kind of repair starts at several thousands of dollars and can be devastating for home owners.
3. Cutting down trees
Cutting down a tree can seem like a small task anyone can do. Home owners should always hire a professional for this service. Even smaller trees can be awkward and are hard to control once they are fall and can crash into a home or garage/shed. Fixing a repair from a tree taking out the roof is much more costly than hiring for professional removal.
4. Drilling into walls carelessly
Much like removing a tree, hanging décor or shelves can seem like an easy job. However, one must be very cautious when putting holes in the wall. Behind the walls, there could be electrical wires and cables, duct work and plumbing pipes that could be damaged by a drill. To prevent costly errors, use a stud finder to help avoid wires and ducts. Even if a stud indicates clear to drill, only drill about 1.25 inches in to avoid hitting anything important.
5. Not insulating
Not only is a house uncomfortable when it is too hot or too cold, it is also very costly to the home owner. Check the attic for insulation depth to know if a home needs to be insulated. Home owners should know where the entrance to the attic is, and how deep the insulation is. If insulation is not 10-14 inches deep, new insulation should be put down. Also, ensure the hatch to access the attic has insulation covering it as well to ensure minimal air leakage.
6. Not cleaning gutters
Cleaning gutters is a chore many people hate. It can be a pain to get on a ladder and clean filthy debris from above. However, neglecting this task can mean serious water damage to the roof and the home in general. Clogged gutters can interfere with proper water flow from the property. Clean gutters will ensure water flows away from the house and not into it.

Care for Your Furnace to Keep Warm All Winter

All furnaces are not created equal. Some will sputter through the cold winter season and put out just enough heat to keep you from freezing to death, while others keep you plenty toasty, but at a utility cost that breaks the family budget! If you have an antiquated furnace, it just may be a good idea to have a professional take a look at it to see if some repairs could help. Often a furnace repair or even a replacement can actually pay for itself with the savings on your heating bill.
The best time to have your furnace checked out is in the summer or early autumn – in other words, before you actually need it. The reason for this is that many heating companies will offer discounts during that time. The other reason is that the last thing you want to happen is for it to fail in the middle of a winter storm when you might not be able to get someone to help you right away.
A heating professional will check out a number of things on your furnace. They will check the thermostat to make sure it is operating correctly and cycling the furnace appropriately. They will check out the venting systems to determine if there is any wear that needs to be addressed.  A serious problem is when there are wires that are frayed and thus a fire hazard, so having a professional check out and repair your furnace system could actually save your home and your life.
If your furnace is quite old or needs some costly repairs, a professional will be able to advise you on the cost to replace the furnace and how much of that you can recoup from lower heating costs from that point forward. In recent years, furnaces have been developed that are so efficient, they can cut your costs by hundreds of dollars each year.
Neglecting your furnace can be expensive and hazardous, so whether you choose to just have your furnace serviced and/or repaired to save some money or you opt to replace your furnace, the best way to get started is to call a furnace repair professional before winter.

Winter Furnace and Home Myths Dispelled

As the winter months press on and the cold temperatures stick around, many homeowners will start to rely on the myths and fables they hear to reduce their utility bills, or warm their home. Don’t be fooled by heating myths. We have four myths homeowners should be aware of during the cold winter months.
Myth: Reduce the heating bill by closing vents and registers.
Most newer model homes have forced-air heating systems, which balance pressure to equally distribute heat throughout the home. By closing off vents and registers the balance is thrown off causing the heating system to work much harder to heat the home.
Myth: Your house will heat up faster if you set the thermostat higher.
Heating systems deliver air at the same constant rate no matter how high the heat is set. If it is cold and the thermostat temperature is set to 80 degrees to “quickly” warm the house, you will find the heating system will just run at the same rate until it reaches the desired temperature.
Myth: Adjusting the thermostat while gone won’t do anything for your bill.
The warmer you keep the house, whether in it or not, the more your utility bills will cost. Reducing the temperature while you are out can significantly reduce the utility bill. According to TXU Energy and Gas, the ideal home temperature in the winter is 78 degrees. Setting the thermostat to 74 degrees can reduce the monthly heating costs by 32 percent because less energy is being spent on keeping the home at 78 degrees.
Myth: Cold floors are a part of winter.
A cold kitchen or bathroom floor during winter may be because your home is not properly insulated. Homes should be able to keep warm air in and cold air out during the winter months. If your floors are abnormally cold, check for air leaks around windows, doors and ductwork. It may just mean that you need to seal your home to reduce the cold drafts from occurring.

How To Get The Most Value Out Of Your Furnace

Are you in the market for a new forced-air gas furnace? New Jersey weather makes a high efficiency furnace a good investment. Some of the features to look for are an AFUE of 90% or higher, multi-stage firing, and an ECM fan blower motor.
Insulate First: Before you buy a new furnace, it is a good idea to seal air leaks and add insulation to your walls and ceilings. Adding insulation and sealing air leaks will make your home more comfortable and may enable you to purchase a smaller furnace.
Select a Furnace with an AFUE of 90% or Higher: The Annual Fuel Utilization Efficiency, or AFUE, measures a furnace’s overall energy performance. The higher the AFUE, the more heat you get for your heating dollar. In New Jersey, a furnace with an AFUE of 90% or higher is a good investment.
Select a Furnace with Multi-stage Firing for the Right Size Furnace for All Heating Conditions: Your furnace must have enough capacity to meet your heating needs on the coldest day of winter. However, for most of the heating season, it will be more heating capacity than you need. Unlike a furnace with single-stage firing that is either firing at full output or completely off, a furnace with multi-stage firing can selectively turn some burners off when full furnace output is not needed. Multi-stage firing gives you the right size furnace for the majority of the heating season, and a reserve capacity to meet additional heating needs on really cold days or to recover from a temperature setback period. Multi-stage furnaces are usually equipped with another efficiency feature as well: an electronically commutated motor (ECM) that uses considerably less electricity to run the fan.
Select a Furnace That Uses Electricity Efficiently: A gas furnace uses electricity to run the fan blower motor. Furnaces equipped with an ECM have lower annual operating costs and can save you $40 to $300 per year depending on how you use the furnace fan. An ECM will save the most if you run your furnace fan all the time. Multi-stage ECM furnaces not only save you money, they are usually much quieter and less prone to producing unpleasant drafts.

Proper Installation is Important: Your new furnace must be installed properly to ensure that it operates safely and efficiently. The contractor should adjust the air flow so the furnace fan setting is matched to the ductwork and furnace characteristics. An improperly installed furnace can result in higher energy costs and a less comfortable home. Make sure the ducts are well-sealed and balanced. Insulate and seal ducts that go through unheated areas. If you upgrade to an energy efficient furnace that vents out the side of the house and you are no longer using your chimney,you can seal it off for additional savings.
Operating Tips:

How you operate your heating system will influence how much energy you use. The following tips will help lower your heating bill and ensure that your furnace functions safely and efficiently:

  • Set your thermostat between 68 and 70 degrees when you are at home. Turn down the thermostat when you are away or sleeping. Regularly lowering your thermostat temperature by five degrees for eight hours every day will save about five percent on your heating bill. Use a programmable thermostat to adjust the temperature automatically, based on the time of the day and the day of the week.
  • Leave the fan switch on your thermostat set to “auto” unless you have a specific need for additional air circulation. Some customers choose to operate their fan continuously to even out warm and cold spots in their home, or to provide extra air filtration which may be beneficial where occupants have health concerns. Setting the fan to “on” will cause it to run all the time whether or not there is a need for heating or cooling. Those extra hours of operation can add several hundred dollars to your annual electric bill. If you do need to run your fan continuously, install a furnace with an ECM. Running the fan year-round will cost only about $50.
  • Clean or replace furnace filters as recommended by your contractor or as noted on your filter packaging. Filters may need to be replaced as often as once a month.
  • Be sure registers in occupied rooms aren’t blocked by furniture or draperies.
  • Have your furnace tuned up every other year unless the manufacturer indicates otherwise. The contractor will test the efficiency, adjust the air and fuel flow, inspect the fan, and clean the unit.
  • Install carbon monoxide detectors on every floor with a bedroom. Carbon monoxide detectors are not a substitute for properly maintaining your combustion appliances, but provide added protection against carbon monoxide poisoning.

New Year New Furnace! Tips for Purchasing a New Furnace

WHAT TO KNOW BEFORE YOU BUY

If you’re in the market for a new furnace, there’s some information you need to know before you make your purchase.

Variable Speed

A furnace with variable-speed technology lets you take control of your comfort and energy bills. This feature ensures a home receives the precise amount of air required to keep a family comfortable. Besides providing exceptional comfort, this technology also saves homeowners money on their energy bills because the efficient variable-speed motors consume less electricity than standard furnace motors. Typical furnaces operating in the continuous fan mode consume 400 watts of energy – while some furnaces with this technology use only 60 to 80 watts.
Variable speed operation can also help control high humidity, reducing the chances of airborne mold growth and other indoor air quality problems. The continuous fan mode works well with indoor air quality products, such as filters, because it operates at a slower speed, allowing them to capture more contaminants.

Two-stage Heating

A furnace with two-stage heating can be a tremendous help when looking for that just-right temperature during the cold winter months. Furnaces with two-stage heating can reduce temperature swings in the home. Unlike traditional furnaces, which operate at their full heating capacity, two-stage furnaces are designed to operate like two separate furnaces and maintain more consistent comfort levels throughout a home.
Two-stage heating has many comfort advantages. The temperature inside a home should vary only a few degrees versus the larger temperature swings that are common with traditional furnaces. The first stage consists of the furnace running at about 68 percent of its heating capacity. A two-stage furnace will always start in the first stage and attempt to meet the heating demand. This reduced capacity is enough to warm a home on mild winter days. When temperatures drop, the furnace adjusts itself and enters the second stage to meet the demand for heat within the home.

High Efficiency

If you want to save money on your heating costs, consider purchasing a high efficiency furnace. They can help reduce your energy costs as well as conserve our natural resources. When selecting a furnace, pay close attention to the Annual Fuel Utilization Efficiency (AFUE). The AFUE number represents how efficiently a furnace converts fuel to energy. The higher the AFUE percentage, the more energy-efficient or fuel-efficient the furnace. The U.S. government’s minimum AFUE rating for a furnace is 78 percent.
It’s also important to look for Energy Star products. This means the product meets the Environmental Protection Agency’s (EPA) standards by using less energy, which reduces pollution. Energy Star products reduce energy use by 20-40 percent.

Quiet

If you want a quiet unit, you should look for a furnace that has the variable speed and/or two-stage features. Other things to look for include insulation in the blower section and enclosed burners. These items help keep sound levels to a minimum.

High Quality

If you want a high quality furnace, make sure it has earned the Good Housekeeping Seal. This reputable seal is a two-year limited warranty and is earned only after a product clears the review and evaluation process of the famous Good Housekeeping Institute. If a product bearing the seal proves to be defective within two years of purchase, Good Housekeeping will replace the product or refund the purchase price. Good Housekeeping is not responsible for installation.

Warranty

It’s also important to look for a furnace that offers good warranties, such as a 20-year limited warranty on the heat exchanger and a 5-year limited warranty on all remaining covered components.

Accessories

Programmable or setback thermostats can be purchased separately. These thermostats make a big difference by delivering maximum comfort, efficiency, and energy savings. Programmable thermostats are used to achieve the temperatures you want throughout your home. For example, if you’re going to be away, you can set the whole house at an energy-saving temperature to avoid heating an empty house. If you have programmable thermostats, you can program them to have your living areas comfortable when you arrive home.
Indoor air quality products that are installed as part of the system can make your home environment healthier. These products include high efficiency air cleaners, humidifiers, and ultra-violet lights. When replacing your furnace, it’s a good idea to also consider the quality of air in your home, especially if you or anyone in your household suffers from allergies.
Zoning can drastically lower your heating costs. You won’t have to heat or cool the whole house just to make one room comfortable. Zoning divides your home into separate comfort areas, which are heated or cooled based on your needs. If you have any questions call your friends at Green Apple Mechanical toll free at 888-611-7191

Tune Up Your AC and Heating Systems in the New Year

Looking for ways to save money, time, and hassle when the new year comes?
 
An HVAC system can become quite a hassle if it breaks down without warning, if temperatures get difficult to control, or if it ends up drastically increasing your monthly bills. Start saving today by setting some time aside for an annual maintenance visit.
 
Annual tune-ups save time
 
Problems within your heating and air conditioning systems may remain hidden for months, slowly overworking your HVAC system until you’re stuck dealing with a broken down unit on a very hot (or very chilly) day! But a technician has the right equipment to thoroughly inspect your HVAC equipment and look for failing parts that require your attention ASAP.
 
A tune-up can help you save money in more ways than one
 
After the inspection, your maintenance visit involves a few adjustments to the components of your HVAC system. Slight adjustments to temperature settings, cleaning the coils, tightening electrical connections, and more all help to improve the condition of your HVAC system. When the parts run more smoothly, they use up less energy!
 
Plus, making a repair early on may require less labor and a less expensive part. This means that, if a technician finds that something is wrong in the initial inspection, you may spend less making repairs than you would if you waited for the system to break down months later.
 
Now is the time to save!
 
Make a commitment in the new year to schedule 2 tune-ups, one in the spring (or as early in the year as possible) and one in the fall. Program a reminder into your phone, write in on a calendar, or ask your local technicians if they offer an annual maintenance programs.

 

Signs That You Need a New Furnace In The New Year!

We all make new year’s resolutions in order to better ourselves. But sometimes, in order to make our lives better, we need to let certain things go and move on.
One of those things might be your furnace. It had a good run, but now might be the time to get it replaced. So, here we’re going to show you the top six warning signs that you need to replace your furnace.
Separately these signs may not be enough reason to replace your furnace, but the more signs that apply to your furnace, the more likely you need a new furnace.
1) Your furnace is more than 15 years old
According to Consumerreports.org, the average life expectancy for a gas furnace is 18 years.
However, according to Energystar.gov, you should replace a furnace that’s over 15 years old with an ENERGY STAR rated furnace, which is 15% more energy efficient than other furnaces on the market.
To learn more about how much money you can save by upgrading to a new energy efficient furnace, read up on AFUE ratings, which measures furnace energy efficiency.
2) Your heating bill increased
A variety of problems could be causing this. But if you have repaired your furnace by a reputable heating company and had your air ducts properly sealed, your energy bill shouldn’t increase dramatically.
A sudden increase in your heating bill from the years before may mean that your furnace is on its last legs. As internal parts wear out, your gas and electric bill may go up.
The extra money you’re paying in gas and electricity could go towards buying a new furnace.
3) Your furnace has been repaired frequently the past two years
Furnaces incur the most repairs during the last two years of their lives. Like a repairing an old car, It doesn’t take too many repairs before keeping your old furnace running isn’t worth the cost.
Add up the cost of repairs to your furnace over the last two years and see if it’s cost efficient to buy a new one.
4) Your furnace makes strange noises
When you turn on your furnace, does it make any rattling, popping, or banging noises? Older furnaces make these strange noises at the end of their life.
Also, does your blower turn on and off frequently? Does it blow cold air? This is another sign that your furnace needs to be replaced by a professional heating company.
5) Thermostat setting never keeps you comfortable
Are some of your rooms too hot or too cold? Are you constantly adjusting the thermostat to stay comfortable? If so, it may be because your furnace can no longer distribute heat properly throughout your house.
6) Your burner flame is yellow instead of blue
If your furnace’s flame is yellow instead of blue, it could be a sign that your furnace is producing carbon monoxide.
Carbon monoxide is a odorless, tasteless, and colorless toxic gas that can be fatal.
Other signs that your furnace is producing carbon monoxide include:

  • streaks of soot around furnace
  • absence of upward draft in chimney
  • extra moisture found on windows, walls, or other cold surfaces
  • rusting on flue pipes or other pipe connections

If your furnace shows signs of producing carbon monoxide, leave your house and call your utility company to turn your gas off. (And consider purchasing a new furnace if the problem is serious.)
Add up the signs
How many of these signs apply to your furnace? The more that apply, the more you should consider buying a new furnace from a trusted heating company.
And remember that buying a new furnace won’t save you much money if it’s not properly installed.

Signs You Need A New Furnace For The New Year

Repair or replace? Every homeowner in New Jersey faces this problem when their furnace breaks down.
Replacing your furnace is expensive, but the savings you can get from a new furnace can be worth it in the long run due to fewer repairs and increased energy efficiency.
So how do you know it’s time to replace? Here are five signs that your furnace needs to be replaced in order to save the most money in the long run.

Over 15 Years Old

According to Consumerreports.org, the average lifetime for a gas furnace is 18 years. But Energystar.gov suggests replacing furnaces that are over 15 years old with an ENERGY STAR rated furnace.
These furnaces are at least 15% more energy efficient than other new furnaces that only meet minimum federal standards.
After 15-18 years (depending on the brand), repairing the furnace could be like putting new tires on a car with 400,000 miles.

Needs to be repaired frequently

Older furnaces break down more often near the end of their lives. While most HVAC companies would be glad to take your money from you for frequent repairs, a reputable heating company will tell you if the furnace needs to be replaced instead.

Higher heating bills

Furnaces decrease in energy efficiency over time as their internal parts begin to wear out. This increases your heating bill because they have to run longer to achieve the level of heat you desire.
Newer furnaces are much more energy efficient than older ones, so you can recoup the costs from a new furnace in a few years.

Heat in home isn’t distributed equally

Are some of your rooms are too hot or too cold? Are you constantly adjusting the thermostat to stay comfortable?
There may be a multitude of causes for this uneven heating. However, if you have an older furnace and the problem has only surfaced recently, your heater is likely the cause. An old furnace has trouble distributing heat throughout your home and may need to be replaced.

Leaks Carbon Monoxide

Furnaces with a damaged heat exchanger leak carbon monoxide (CO) – an odorless, tasteless and colorless toxic gas that, when inhaled, causes dizziness, headaches and nausea. Prolonged exposure leads to brain damage and death.
While you can’t see CO, you can see warning signs of it including:

  • yellow pilot light instead of blue
  • soot marks around the furnace
  • moisture accumulates on windows or walls
  • rust on flue pipes.

To catch CO leaks before anyone gets hurt, it’s wise to install a carbon monoxide monitor that alarms you when a certain amount of CO has filled in your home.

Why It’s Important To Change Your Furnace Filter

Many heating and cooling contractors will tell you that it is important to change your furnace filter every month. You may think that it is not that important and is just another thing you need to add to your already long list of chores. What you need to know, however, is why it is so important and how it will save you money in the long run.

Clean Furnace Filters Save Money

A furnace filter that is clogged with dust, pet dander, and other particles will cause your furnace to work harder because of decreased airflow. When this happens, you will need to make repairs more often to replace worn out parts. Overtime, the useful life of your furnace will be reduced as a result.
Being your furnace has to work harder, this means it is using more energy to operate. By changing its filter monthly, you will help reduce your home’s heating costs.

Better Air Quality

The EPA estimates that the air we breathe inside our homes can be up to five times more polluted than the air we breathe outdoors. The purpose of having a filter in your furnace is to reduce the amount of dust and other allergens that can be circulated throughout your home and add further to this problem.
Even if you keep your home immaculate, dust, pollen, pet dander, mold spores, and or bacteria can still be found within it. If your furnace filter is not changed regularly, these irritants will continue to build up and foul the air quality inside your home.
As a result, your family’s health may suffer, especially those members who suffer from asthma or allergies. If your family seems to be getting more colds than usual or are constantly suffering from congestion, your filter may be at the root of the problem.

Tell-Tale Signs It’s Time to Replace Your Filter

  • If you start noticing more dust around your home, or dust around your air vents
  • You smell a dusty odor in your home
  • You or your family has unexplained congestion

To keep your furnace in its best condition, Green Apple Mechanical NJ recommends that you change the filter monthly and have it serviced annually by a professional heating and cooling contractor. This will ensure that your furnace will continue to keep your home warm and comfortable when you need it most.
For any questions you may have about replacing your filter or servicing your furnace in your NJ home, call the experts at Green Apple Mechanical NJ at  888-611-7191. We will be happy to recommend the best type of filter for your furnace and explain to you the benefits of keeping your furnace well-maintained.

Common Gas Furnace Problems

Thermostat Problems

The first thing to check is the battery. Most digital thermostats have a battery indicator on the display. If you see an icon in the display asking for a battery, follow the manufacturer’s instructions and replace the battery with an appropriate size.
If you see no display at all, check the power to the furnace. This particular thermostat has a sealed battery in it, and it’s not replaceable.
If you’ve checked the battery, you’ve checked the power supply, and your thermostat is still not operating properly, it’s likely that you’re just going to have to replace your thermostat. It’s important to understand how your thermostat operates when it’s normal, when everything is right. If you’re familiar with the proper operation of your equipment, then it’s going to make it easier if you notice something acting unusually and you can call Green Apple Mechanical NJ for a proper diagnosis.

Mismatching Furnace and Thermostat

Your home’s gas furnace needs to be paired with the correct thermostat to work properly; if it isn’t, you could run into problems.
Thermostats have to be matched to the system based on the type of furnace that’s used and the capacity and capability of that furnace. The best way to make sure you’re going to have a thermostat that matches your system is to get it from an HVAC professional.

Electronic Ignition Furnace Problems

To determine what type of ignition system you have, open the front of the furnace and initiate a call for heat. Observe what happens in the burner area. If there’s a very small flame that starts first, and then ignites all of the main burners, that’s an intermittent pilot type of ignition. If the ignition happens and the main burners come on immediately, then that’s a direct ignition.
Once you determine which type of ignition system you’ve got, if you see it operating in a way that’s not correct, it’s best to call an Green Apple Mechanical NJ service technician as soon as possible. It’s important that you are  aware of how the system is supposed to operate when everything is normal. So that way when things do change, you can be aware of it and call for service before it becomes a bigger problem. It’s going to help maintain the equipment, keep it lasting longer, keep it safe, and also reduce your energy costs.

Furnace Has a Noisy Operation

Squeaks, rattles, and rumbles are some of the things that we hear from furnaces. In the case of a squeak, it can be related to a motor failing or just making noise. Rumbling and rattling can be caused by an out of balance blower wheel caused by debris or just age or just being dirty. Early gas furnaces used a motor with a belt to drive the wheel. That’s the blower that moves the air into the house. All modern furnaces use a direct drive blower that’s permanently lubricated. It doesn’t require any lubrication or maintenance on that.
Squeaks and squeals can also happen from air leaks. There can be a leak in the duct work or around the furnace somewhere that’s allowing a small amount of air to leak in or out causing a whistling or squeaking sound. If you suspect that a high-pitched squealing or whistling noise could be coming from the air flow, what you want to do is check some of the gaps or joints where the sheet metal is connected. Those are the likely sources where that can happen and it can be simply sealed up with tape or a piece of putty or something like that. Sometimes something as little as this door being out of alignment can cause a squeal or a squeak and you can just move it a little bit or just make sure it’s firmly placed where it should be.
So when you look at the burners on a furnace, you can kind of judge the condition. If you see any kind of dust, lint or other kind of dirt in the furnace, that could be clogging one of the burners and causing excess noise in a furnace. In that case, it’s really important to get a professional out to do a proper cleaning on the furnace for you. Knowing a little bit about your system and being educated about it is the best way to stay on top of it and avoid breakdowns. A lot of times when homeowners hear the system operating in an unusual way, they can have us come out and take care of it before it becomes a bigger issue.

Furnace Blower Does Not Turn Off

The first thing to check is the fan switch on the thermostat. “Auto” means that the fan should only be running to try to heat or cool the home to try to match the thermostat setting. If you see the thermostat fan switch set to “on,” or “low,” “medium,” or “high,” then you’re going to have continuous fan operation.
The next thing to look at is your furnace filter. If you find a clogged filter, it may have caused damage to the limit switch. What the limit switch does is it senses the temperature inside the furnace. If it sees a temperature that’s too high, then it shuts off the fire as a safety and only will allow it to come back on once it’s cooled sufficiently. If the filter has been clogged for too long, then it may have damaged that switch to the point where it needs to be replaced. In this case, the furnace high limit is a small button type device that’s got two wires connected to it. Every furnace is a little bit different. Some of them have more than one limit, and some of the limits look very different. If that limit switch is failed, it’s very important to find the source of why it failed and not just replace the switch. It’s a very important safety issue.

Furnace Cycles On and Off Too Frequently

If you notice the frequency of the heat cycles becoming too short, that’s an indication of a problem with your system. The first thing you want to check is the fan switch on the thermostat. In this case, it’s up here in the display and it says “auto.” Now, “auto” means that the fan should only be running to try to heat or cool the home to try to match the thermostat setting. If you see the thermostat fan switch set to “on,” or in this case “low,” “medium,” or “high,” then you’re going to have continuous fan operation.
If your filter has been in the furnace for a long time and its gotten very clogged, it can cause the furnace to what we call cycle on limit. That means that instead of heating continuously, the flames turn on and off because the unit is overheating due to that clogged filter.
The important thing with filters is watching the air flow direction. There’s always an arrow that tells us which way the air should flow through the furnace. On most furnaces, people have drawn arrows that tells you which way the air flow direction should be.

Furnace Does Not Produce Enough Heat

One of the most common sources of this kind of problem is a clogged filter. It’s very important that you check your filters regularly and change them frequently for good furnace operation and best efficiency. The second possibility is that the furnace was not sized properly, meaning that it doesn’t have enough capacity to keep the home warm. It’s important that a heating and air company size the equipment for the capacity needed to keep your home warm. Another possibility, though it’s pretty rare, could be that your burners could be clogged to the point where it’s not allowing the furnace to create enough heat and meet its full capacity.

Furnace Does Not Heat

Some possible causes of that are: thermostat not adjusted properly, the power going to the furnace could be shut off, the gas going to the furnace could be shut off, or the pilot light could be out. A couple things to check with the thermostat: Now, the first thing to remember is that everybody’s thermostat is going to be different. In this case, when the red light is on, that means that it’s in heat mode, so it’s ready to heat the house. The next thing to check is to make sure the set point is higher than the room temperature. So if we raise that set point above the room temperature, that’s going to turn the heat on.

Furnace Pilot is Out

Some of the common sources of a lost pilot light are a  a strong draft, or a clogged orifice to the gas supply to the pilot light. A thermocouple is a device on a standing pilot system that proves the flame to the gas valve and allows gas to keep flowing as long as there’s a flame sensed. It’s probably best if you have a professional check it out, clean it and verify that it’s working properly. Now, the thing to keep in mind is most modern furnaces don’t use a standing pilot light anymore. Always call your friends at Green Apple Mechanical NJ with any service questions at 888-611-7191
