Your HVAC system is intended to keep your home comfortable and your indoor air clean. While regular maintenance of your HVAC system helps to maximize the life expectancy of your system, there are scenarios where your HVAC system malfunctions, and the only clear indicator of a malfunction is a very distinct odor. For August's Tech Tip of the Month, we wanted to educate and inform you on four distinct HVAC odors that a homeowner should never ignore and what to do should you smell these odors in your home.
Rotten Egg Odor-
- What: As natural gas is odorless, utility companies have added the scent of rotten eggs to the gas supply to help warn of possible gas leaks.
- How to Fix Issue: If you smell rotten eggs in your home that appear to be coming from your HVAC system, we recommend that you open as many windows as possible to air out the house and then leave your house immediately. Once you are at a safe location, it is important to seek professional assistance from your gas company right away.
- What: An electrical or burning smell could signify that your HVAC system's motor has gone bad, your unit has overheated or some electrical wiring has been torn or damaged.
- How to Fix Issue: If you smell an electrical odor coming from your HVAC system, we recommend that you turn off your unit by the master shutoff valve and contact your HVAC company immediately to have them come out to address the issue.
- What: A musty smell could mean mold from condensation buildup and moisture inside the system.
- How to Fix Issue: If you smell a musty/moldy odor throughout the air in your home, we recommend that you contact your HVAC company to have them come out to address any indoor air quality (IAQ) problems that you may have and to provide IAQ solutions to remedy the issue.
- What: A formaldehyde odor could indicate a cracked heat exchanger, which means that CO gas could be leaking into your home's air.
- How to Fix Issue: If you smell a chemical odor coming from your HVAC system, we recommend that you open as many windows as possible to help air out the house and then leave your house immediately. Once you are at a safe location, it is important to see professional assistance from your HVAC company right away.
Should you ever smell any of these odors in your home, it is always best to call your HVAC company or gas company for recommendations on how to handle the situation. For any further details, please call our office at 610-642-6323 or visit our website at www.bobsredtrucks.com.
