If the cool air from your air conditioner has an upsetting smell, you’re probably wondering what could be wrong with it. There are many common causes, but it can be a puzzling problem for homeowners.
Here are some potential reasons your air conditioner smells and a few tips on how to get rid of bad smells from an air conditioner.
Mold or Mildew
Fungi in your home are anything but fun. Unfortunately, they’re also a typical reason you might be dealing with a sour air conditioner smell. The moist environment in your air conditioner can often be the ideal breeding ground for mold.
The odor circulates throughout your home as air passes over the mold or mildew. If you’re noticing your air conditioner smells musty, it’s probably a mold-related problem.
Smelling Smoke
If you smell smoke from your air conditioner, address it immediately as it can be a safety hazard. The burning smell may be due to electrical problems, an overheated motor, or debris inside the unit.
Electrical issues, like frayed wires or a faulty capacitor, can create sparks and smoke. An overheated motor can result from overuse or poor maintenance. Dust and debris can also burn and produce a smoky odor. Turn off the air conditioner and contact an AC repair expert to inspect and repair the system to ensure safety and prevent further damage.
Dead Animals
It’s certainly not the most pleasant thing to think about, but sometimes small animals like rodents or birds can find their way into your ductwork or unit and, unfortunately, pass away. Decomposition can create a very distinct and unpleasant odor.
The good news is that this issue is often relatively simple to resolve with a professional cleaning from HVAC experts. Once the source of the air conditioner smell is removed, the situation should immediately improve!
Clogged Drain Lines
Your air conditioner not only cools the air but also removes humidity. This process creates condensation, typically draining away through a designated line. But should the drain line become clogged with dirt, algae, or other debris, the stagnant water can smell musty or even slightly sour.
A professional HVAC technician can assist with cleaning clogged drain lines. However, you can prevent this issue in the future by checking and flushing your lines regularly.
Tips for Prevention
Now that you’re clear on the common causes, here are some tips to prevent experiencing another funny smell out of your AC:
- Keep up on system maintenance
- Schedule annual or biannual professional inspections
- Use an air purifier or dehumidifier
- Remember to change filters regularly
The most important tip is to maintain your AC with the help of an industry professional. This ensures your HVAC is always in tip-top shape, significantly lowering the chances you’ll experience a foul smell from your unit.
