Why Does My A.C. Smell?
When your air conditioner kicks on, the last thing you want is a funky odor spreading through your home. If you’ve been asking, “Why does my A.C. smell weird?”, you’re not alone. Strange smells from an air conditioner are one of the most common complaints during the hot Arkansas summers. These odors can signal anything from simple maintenance issues to more serious HVAC problems that need professional repair.
At Riverside Comfort Care, we help homeowners in Fort Smith, Van Buren, Alma, and Greenwood, AR solve A.C. odor problems quickly so their homes stay comfortable and safe. Let’s break down the most common culprits behind smelly air conditioners and what you can do about them.
Common Causes of Air Conditioner Odors
1. Mold or Mildew Growth
One of the most frequent reasons your A.C. smells bad is mold or mildew inside the system. Since air conditioners create condensation, moisture can collect in the drip pan, ducts, or evaporator coils. If that moisture doesn’t drain properly, mold and mildew can thrive, producing a musty, dirty-sock smell.
Solution: Schedule professional duct cleaning and system maintenance with Riverside Comfort Care. We’ll clean out mold-prone areas and ensure proper drainage so your system stays fresh.
2. Clogged or Dirty Air Filters
If you haven’t changed your A.C. filter recently, odors can get trapped and circulate through your home. Dust, pet dander, pollen, and other debris build up inside the filter and create a stale or dirty smell.
Solution: Replace your air filter every 1–3 months, depending on usage. If you need high-quality air filters in Fort Smith, AR, Riverside Comfort Care can help.
3. Refrigerant Leaks
A refrigerant leak doesn’t just cause cooling problems—it can also create a chemical or sweet smell. Refrigerant is hazardous to breathe, so if you notice this odor, shut off your system and call for repairs immediately.
Solution: Contact Riverside Comfort Care for emergency A.C. repair. Our technicians are trained to handle refrigerant safely and restore your system.
4. Electrical or Burning Smells
If your A.C. smells like something is burning, it could mean the motor, wiring, or another electrical component is overheating. This type of odor should never be ignored—it could pose a fire hazard.
Solution: Turn off your system right away and call a licensed HVAC professional in Van Buren or Greenwood, AR.
5. Rotten Egg or Sewer Smell
This smell usually means there’s a natural gas leak or a sewer line issue near your ductwork. Natural gas companies add sulfur to gas so leaks can be detected by smell. If you smell rotten eggs, treat it as an emergency.
Solution: Leave your home immediately, call your gas company, and then contact Riverside Comfort Care once it’s safe to inspect your system.
6. Dead Animals or Pests
Sometimes small rodents or insects crawl into ductwork or your A.C. unit. Unfortunately, if they die inside, the odor will spread through your home.
Solution: Have our team inspect your ductwork and system. We’ll remove any debris and recommend ways to prevent pests from entering your system again.
Why Odors Worsen in Late Summer
As the Arkansas summer stretches into back-to-school season, your A.C. works overtime. High humidity plus heavy usage means your system produces more condensation, which increases the risk of mold growth and stagnant odors. If your A.C. hasn’t been serviced since spring, this is the time when smells often become noticeable.
Regular HVAC maintenance not only improves air quality but also prevents costly repairs during the hottest months.
