As spring and summer approach, the weather is getting hotter in Spring, Texas. AC Repair may be a part of home care as you dive into the warmer weather, especially if you are noticing odd smells coming from your vents or air conditioning unit. Occasional smells are not unusual when the seasons change, but it is important to know what they mean and when to contact an AC Company in Spring, Texas.


A common problem you encounter in HVAC units is a mildew smell that may have musty fragrance. This occurs when condensation builds up from your AC unit and leaks into ducts causing mold buildup. Mold is a serious hazard to your health and leaving it untended exposes you to the risk of respiratory conditions. It’s important to contact an air conditioning company in Spring, Texas if you are experiencing mold and mildew smells.

Dusty Burning

Electrical odors often happen when kicking the heat on in the fall, but they can also be an indicator of a more serious HVAC problem, especially if you are noticing them during the summer months when you are running your air conditioning. A burning smell will often smell like your unit is overheating. Check your air filters to be sure that airflow is moving smoothly and that it is not restricted by dirt and grime. If that does not resolve the smell, immediately turn off your AC unit at the master switch and find a company that can help you with air conditioning repair in Spring, Texas.  It is possible that you have a problem with the motors or wiring – attempting to fix these without air conditioning repair experience could result in severe injuries and should not be attempted.

Outdoor Odors

Your AC unit intakes air from the outdoors, which occasionally is exposed to the smells of the environment around your home. Smells from cars, motorcycles, dead animals, and standing water can make their way from the outdoors into your home.

Dead Animals

In the case of putrid smells, occasionally a dead animal is the source of these nasty smells. Look around your unit and in your vents to see if an animal carcass is causing the smell. If you remove the carcass yourself, be sure to use gloves to prevent the spread of germs and diseases.  You may need to contact an air conditioning company in Spring, Texas to do a thorough cleaning of your vents and ducts,


Occasionally, sewage lines do backup and can leak methane gas. If that happens near a duct and methane gas is able to enter into your ductwork, it is able to make your home smell like sewage or rotten eggs.
