Trouble Shooting a Smelly Air Conditioning Unit

There's nothing quite as rejuvenating as walking into a cool, temperature-controlled home after a day in the hot Texas sun.


And the best time to make sure your AC unit is ready to handle the rigors of the hot season is right now.


When you turn on your unit after not running it for a while, it could take a few minutes for the AC to catch its rhythm. Should you notice an odd or musty odor shortly after adjusting your thermostat cooler, it's worth reaching out to a professional HVAC repair company such as AC Texas.


Potential Causes Of A Smelly Air Conditioning Unit


Mold And Mildew - Air ducts and vents can accumulate moisture due to high humidity, leaks, or inadequate drainage. If you notice a musty scent when your air conditioning is running, there could be mold or mildew in your unit or ductwork.


Exposure to mold and mildew can pose a severe threat to your health and wellbeing, so you should call your HVAC technician to troubleshoot the issue and complete any needed work.


Evaporator Coils Are Frozen - For HVAC units to work correctly, free-flowing air is a necessity. Blockages, such as dirty air filters, vents, and fins, prevent air from moving through the unit. If this happens, there's a potential that your evaporator coils can freeze.


Drain Pan Is Full - The drain pan of your HVAC unit collects the water droplets that condense during the cooling process. If the drain pan is full, it can form mold and mildew that creates a recognizable scent when your unit is in operation. An HVAC technician can complete total troubleshooting and make any needed repairs.


Electrical Issues - If you notice a scent that reminds you of smoke, gun powder, or burning, this could indicate your circuit board or fan motor has shorted out. You should immediately shut off your HVAC unit and call a qualified HVAC technician to diagnose the problem and make needed repairs. By doing so, you're taking the right steps to avert more extensive repairs that can stem from problematic electrical issues.
