Are Strange Smells Coming From Your Air Conditioner?

Are Strange Smells Coming From Your Air Conditioner? | Huntsville, TX

It’s time to organize and tidy up your car for spring cleaning. After months of ignoring your air conditioner, the arrival of warmer weather will have you reaching for the AC every time you get in the car. If you notice a foul odor coming from your vehicle’s AC, take it in to Wiesner of Huntsville for expert service from trained technicians.

Sour Smells

A dirty cabin filter clogged with dust and bacteria will lead to a sour stench. Simply replacing the filter should eliminate the smell and get your AC back on track.


If turning on your air conditioner causes a fragrant mildew aroma to waft throughout your car, it could be due to the under-the-hood air intake vent being clogged with dust and wet debris, which over time will grow mold and mildew if not replaced.

Chemical Odors

Leaking refrigerant out of your AC evaporator is a common cause of a chemical-like aroma emitting from your AC. The refrigerant’s sticky oil will trap debris, dirt, and dust onto the evaporator fins, which will limit airflow. If your fan is blowing but no cool air is coming out, leaking refrigerant is likely your problem.

Sweet Scents

A maple syrup smell is a common indication that your heater core sprung a leak. Don’t be fooled by the sweet scent; bring your car in for service at your earliest convenience.

Any unusual odor is cause to take your vehicle in to Wiesner of Huntsville for a thorough AC inspection.

Maintaining Family Vehicles in Huntsville, TX

Maintaining Family Vehicle | Huntsville, TX

Keep your family vehicle working properly by performing regular maintenance and service. While family crossovers, SUVs, and other models need just as many oil changes and other forms of maintenance as any other vehicle, there are a few things that are especially important for family vehicles. These include checking the brakes, cabin maintenance, tire care, and more. Read on to find out why maintaining family vehicles is so important.

Brake maintenance is key for family vehicles, as it not only maintains stopping power but also gives you added peace of mind. Your brakes should be checked at least once a year, but you should also bring your car in if you notice squealing when you stop or pulsing in the pedal. You can bring your car to our Wiesner of Huntsville service center for a brake check or for new brake pads and/or rotors.

Checking the HVAC and cabin air filter is also important to keep your family comfortable on the road. You should replace the cabin air filter every 15,000 to 25,000 miles, approximately once every year or two. The HVAC system should also be cleaned and inspected, and the air conditioning recharged.

Tires are especially important to service on family vehicles to maintain safety. You should check tire pressure with every change of season, but also look for tire wear. If there’s any cracking, bulging, or bald spots on the tread, you’ll need new tires. Our service team can inspect your tires to make sure they’re still working properly, replacing tires when necessary.
