1. Rising Energy Bill

It is normal for energy costs to fluctuate throughout the year. The more demand that is put on your system when the weather reaches extreme temperatures results in higher energy costs. However, these changes should not be occurring inexplicably. If you notice that your energy bill is rising, monitor your gas or electricity rate, usage patterns, and weather conditions. If none of these have changed significantly and your bill is still rising, it is likely that your system is not performing as efficiently as it should be.

2. Reduced Indoor Air Quality or Airflow

High-quality indoor air is a critical component of the healthy environment of your home. A warning sign that your HVAC system could be failing is if you notice your indoor air quality becoming worse. Although this can be difficult to diagnose, pay attention to any symptoms that you or someone in your home may develop, including irritations of the eyes, nose, and throat, mental fatigue, headache, airway infections, or a cough, as they can indicate poor indoor air quality.

3. Unusual Smells

Unusual smells can be a definite warning sign that something is wrong with your HVAC system. Specific smells to keep in mind are as follows:

  1. Rotten Egg Smell – If you smell rotten eggs, you most likely have a natural gas leak.  This can be incredibly dangerous and should be handled by a professional immediately. Evacuate the home and do not return until the situation has been addressed by a professional.

  1. Electrical or Burning Smell – If it smells like something is overheating, there is a good chance that something actually is. Electrical issues can occur with the motor and various other components within the unit.

  1. Moldy or Musty Smell – If you smell a musty or moldy smell, it is typically the result of mold. Due to the potential for moisture to escape from the unit into the ducts, it’s possible for mold to grow and accumulate. Since mold is unsafe to breathe, it is important that you contact a professional to investigate the situation and clean the air ducts to not only resolve the problem but also make changes to reduce the risk of it from happening again in the future.
