A metal-on-metal sound can often be caused by the fan motor bearings going out on your outdoor unit.

Knowing the signs that you need your AC repaired can prevent more significant repairs or even failure. Catching a problem early within your HVAC system is important. Be attentive to how your AC is functioning, and it could save you money and frustration of bigger problems. So, check in on your AC system periodically and be familiar with these signs (or to be replaced).

 Little to no airflow

The sign of weak airflow often indicates a problem with either the compressor or air ducts and is something that your Green Apple Mechanical  HVAC tech should evaluate.

 AC is blowing warm air

Warm air coming from your vents is one of the signs your AC needs repair. It could indicate a problem with the compressor or that your system is low on refrigerant. It could even mean that you have a duct problem somewhere that is pulling air from outside or an attic space rather than from the compressor.

 Unpleasant odors coming from the AC

Odors can be indicators of multiple issues, but two of these issues are electrical issues and mold. If you smell a musty smell from your AC, there is likely mold in your system somewhere, and blowing the spores into your home will cause it to spread and also make your family very sick. However, if you notice a strong burning smell, there is a good chance you may have a problem with the electrical wiring or the insulation around it in the unit.

 Unusual sounds coming from the AC

Here are a few of the sounds and what they might possibly mean for your AC system:

Clicking from the outdoor unit as it runs. This could mean a small obstruction in your outdoor unit’s fan. You should inspect the fan and remove anything that could be striking it as it runs.

Clicking from outdoor unit and won’t turn on. This clicking sound could indicate an electrical problem in one or more system components.

Bubbling or gurgling noise. Your condensate drain line is likely gurgling. If this is your only problem, it will likely not cause any bigger problems. However, you may also have a refrigerant leak that would lead to bigger issues.

Clanging or banging sound from the outdoor unit. This noise is likely an indicator that the fan in your outdoor unit is hitting something. There may be a larger obstruction or the mount of the fan may have come loose. If that is the case, the wobbling is causing it to hit the protective cage around it.

Squealing sound coming from the indoor unit. A squealing noise is usually a good indicator that there is a problem with your fan belt. The sound may come and go, making you think that it’s not a big problem. However, if the belt is damaged, eventually it will break, which would leave you with no working AC.

Metal on metal screeching. If you hear this sound, it is likely coming from your outdoor unit. The metal-on-metal sound can often be caused by the fan motor bearings going out on your outdoor unit.

High-pitched hissing or screaming. This sound is likely from your compressor. This sound can indicate a high-pressure buildup in the system, which can be very dangerous. Your system should be equipped with a safety shut-off switch to automatically shut your system down if this is the case. However, if your system continues to try to function, it is best to turn off your system until your HVAC technician arrives.

 Malfunctioning thermostat

If your AC system is not turning on or only runs for short periods of time before shutting off, your thermostat may be to blame. First, check your batteries and if that doesn’t help, your thermostat may need to be replaced to ensure your system can run accurately again.

 Frequent repairs

If you notice that you’ve had to repair multiple components of your system or unit in the last few months, it may be time to consider a HVAC replacement. Your technician should be able to advise you on the overall state of your system and what the most economical & sound decision should be.

 Humidity in the home

If you find that your HVAC system is no longer helping to reduce the humidity in your home, it is time to call your HVAC repair company. Humidity fosters mold and mildew growth and can cause multiple other issues for your family’s health.

 Moisture leaks in or around the HVAC system

The most serious type of leak you may experience would be a refrigerant leak. Refrigerants are poisonous, so any refrigerant leak is cause for concern. If you have a condensate leak, the drain line for condensation may be blocked or broken.

 Spikes in utility costs

If your power bill suddenly shoots up inexplicably, the efficiency of your HVAC system could be dropping. If you notice a rise that does not seem in sync with the increased use of your AC, it wouldn’t hurt for your Green Apple Mechanical HVAC tech to check things out.

 Age of your system

The last of the signs your ac needs repair is the age of your current unit. Typically, fifteen to twenty years is a good life expectancy for an air conditioning unit. The expense of replacement could be significant, but a new unit will also function much more efficiently and will save money on utility costs, and avoid the headaches of repairs.
