Your HVAC System & What to Listen For

Written by: Metro Air

Your heating and cooling system is a complex machine that has many different components that keep it running smoothly in your Minnesota home. If it’s working properly, you should barely notice when it’s running.  Unusual sounds are often an indicator that something needs professional attention – either a tune-up, cleaning, repair, or even a full replacement. Perhaps the machine is not only making noise, but there are also some unusual odors coming from it, too. This is something to pay attention to.

Want to troubleshoot before you call the experts at Metro Air Heating and Cooling? Here are some of the most common sounds and what they could mean.

Screaming: This could mean there is too much pressure in the compressor. Or, there could be a refrigerant leak. If you hear this sound, it’s don’t use it until it is looked at professionally.

Clanking: Sometimes parts can fall off or be disconnected over time. This could cause a bang or clank sound.

Humming: This could mean there is something wrong electrically, including a wire that’s loose. It’s best not to use the machine if you think there is something wrong with the electrical components. This could cause not only damage to the machine, but it could become a fire hazard.

Screeching: The sounds of metal on metal could mean there is something going on with the motor bearing or there could be a worn or broken belt. These are not things you should attempt to look at or repair yourself.

Sounds coming from your heating and cooling system can be a little frightening! Pay attention to any noises that may signal a potential issue. So, be proactive and don’t ignore the sounds. Call the experts at Metro Air Heating and Cooling can decipher what the noises are and ensure the system is up and running again.

Your dog or cat is part of your family, so keeping an eye on where they are at all times is important. When you let them outside to go the bathroom, try to keep them away from your heating and cooling system unit. Urine causes corrosion over time and that could cause problems that could force you to repair or replace your system prematurely.

#4: Keep your home clean.
Rodents and other pests love to hang out in dirty spaces. So, keeping your yard free of debris and trash will help deter pests. Also, don’t allow water to pool around the system. This attracts pests or rodents that you don’t want. Inside your home, make sure the vents are kept clear so air can flow freely. And last, make sure to clean and/or replace air filters regularly. This helps bolster indoor air quality and keeps the system running at peak efficiency.
