When your air conditioner is fresh and working correctly, you shouldn’t be smelling anything weird. Peculiar air conditioner noises and odd smells are a hint that something is out of whack. If your air conditioner is getting older or you haven’t had service completed lately, they can be a clear sign you need professional air conditioning repair in Tucson and Phoenix.

Here are six of the most common air conditioner smells and how you can resolve them.

1. Central Air Conditioner Smells Like Chemicals

If your air conditioner smells bad when turned on, specifically a chemical scent, it isn’t a positive sign. You might also report your:

  • Air conditioner smells like paint thinner
  • Home air conditioner smells sweet

These sweet, chemical scents are regularly a clue that your air conditioner has a refrigerant leak. Your system needs this gas to move heat through copper coils, which can wear out over time.

Four Signs You Have a Refrigerant Leak

Besides the strange smell, here are four other hints that you have a refrigerant leak.

  1. Bubbling or hissing sounds when your air conditioner is operating.
  2. Ice on refrigerant lines or the evaporator coil.
  3. Trouble keeping your home cool or having your desired temperature.
  4. High utility expenses.

How You Can Take Care of It

A refrigerant leak needs professional assistance from a heating and cooling company like Desert Husky HVAC/R Services. Your cooling professional will find and repair the leak before recharging your AC with refrigerant.

Resolving a refrigerant leak typically costs between $225 and $1,600, based on nationwide averages compiled by HomeAdvisor. Your total cost will depend on the location and severity of the leak, as well as how long it requires to solve.

If your air conditioner was installed prior to 2010, there’s a good chance it runs on R-22 or Freon refrigerant. This refrigerant is no longer being made because of its negative effects on the ozone layer. Consequently, repairs can be extremely expensive so it may be wisest to schedule air conditioning installation in this situation.

2. Air Conditioner Smells Like Gas

If your air conditioner smells like rotten eggs, there’s probably nothing wrong with it. But there’s a significant probability you have a natural gas leak in your home. Natural gas has a sulfur-like additive to signal you when there’s a leak, because the gas can be fatal in big amounts.

How You Can Repair It

If you notice a sulfur or rotten egg odor, we recommend:

  • Switching off your gas supply.
  • Opening windows.
  • Going outside promptly.
  • Calling your gas company without delay.

3. Air Conditioner Smells Musty

People who reach us to report this situation often report their air conditioner smells like feet, dirty socks or a locker room when it’s on. Also known as dirty sock syndrome, this smell is usually linked to a grubby evaporator coil that has mold, mildew and bacteria buildup. Condensation can also make your home air conditioner smell bad. Dirty sock syndrome is most common in climates where you need heating at night and during the morning before transitioning to cooling later on.

How to Solve It

The best approach for preventing dirty sock syndrome is to routinely replace your air filter and schedule annual air conditioning maintenance with Desert Husky HVAC/R Services. We’ll keep the evaporator coil clean and the drainage system unblocked, because excess water can also lead to noxious odors.

4. Air Conditioner Smells Like Vinegar

If you are dealing with air conditioner mildew smell or an acidic, vinegar-like odor, it might be caused by several problems, like:

  • A dirty filter
  • Extra condensation
  • Plugged condensate pan or drain line
  • Moldy air conditioner or ductwork

How to Fix It

Examine your filter first. If you haven’t replaced it within the last three months and can’t see light through it, it’s time to replace it. If that doesn’t fix the issue, reach Desert Husky HVAC/R Services at 520-416-5415.

5. Air Conditioner Smells Like Burning Plastic

If you’re dealing with an air conditioner burning smell or that your air conditioner smells like fish, there could be a number of things wrong. These entail:

  • Broken capacitator that’s overheating the motor.
  • Motor that requires lubrication.
  • Broken fan belt.
  • Electrical malfunctions.

Electrical issues should be examined right away to prevent a fire. If you detect burning plastic when your air conditioner is running, shut it off and contact us at 520-416-5415 right away.

6. Air Conditioner Smells Like Cat Pee

A powerful ammonia odor means there might be mold present in your air conditioner or ductwork. The smell isn’t the mold itself, but the mycotoxins that mold creates.

How to Solve It

Mycotoxins are hazardous to your well-being. That’s why you should have a specialist like Desert Husky HVAC/R Services look at your air conditioner and ductwork and clean it when recommended.
