When your air conditioner is spotless and working correctly, it’s not normal to be smelling anything weird. Unusual air conditioner noises and strange smells are a clue that something is off. If your air conditioner is past its prime or you haven’t had a tune-up completed lately, they can be a clear sign you need professional air conditioning repair in Troy.

Here are six of the top air conditioner smells and how you can fix them.

1. Central Air Conditioner Smells Like Chemicals

If your air conditioner smells bad when turned on, particularly a chemical smell, it isn’t a positive sign. You may also report your:

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

These sweet, chemical odors are regularly a sign that your air conditioner has a refrigerant leak. Your system relies on this gas to transfer heat through copper coils, which can wear out as time passes.

Four hints you are dealing with a refrigerant leak.

In addition to the weird smell, here are four other clues that you are dealing with a refrigerant leak.

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

How You Can Take Care of It

A refrigerant leak needs skilled assistance from a heating and cooling company like Edington Heating & Cooling Inc. Your cooling professional will find and fix the leak before recharging your AC with refrigerant.

Repairing a refrigerant leak usually costs between $225 and $1,600, per nationwide averages assembled by HomeAdvisor. Your precise cost will depend on the location and severity of the leak, as well as how much time it needs to fix.

If your air conditioner was installed prior to 2010, there’s a good chance it has R-22 or Freon refrigerant. This refrigerant is no longer being produced due to its adverse effects on the ozone layer. As a consequence, repairs can be extremely expensive so it may be wisest to do air conditioning installation in this situation.

2. Air Conditioner Smells Like Gas

If your air conditioner smells like rotten eggs, there’s likely nothing wrong with it. But there’s a good chance you have a natural gas leak in your residence. Natural gas has a sulfur-like additive to alert you when there’s a leak, since the gas can be deadly in large amounts.

How You Can Repair It

If you detect a sulfur or rotten egg odor, we advise:

  • Shutting off your gas supply.
  • Opening windows.
  • Evacuating your home as soon as possible.
  • Contacting your gas company without delay.

3. Air Conditioner Smells Musty

Homeowners who call us about this situation frequently say 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 often created by 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 areas where you turn on heating at night and during the morning before transitioning to cooling later on.

How to Repair It

The best way to prevent dirty sock syndrome is to routinely change your air filter and schedule annual air conditioning maintenance with Edington Heating & Cooling Inc. We’ll keep the evaporator coil clean and the drainage system flowing, as standing water can also result in nasty odors.

4. Air Conditioner Smells Like Vinegar

If you are experiencing air conditioner mildew smell or a pungent, vinegar-like odor, it can be the result of several problems, including:

  • A filthy filter
  • Extra condensation
  • Blocked condensate pan or drain line
  • Moldy air conditioner or ductwork

How to Solve It

Inspect 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, call Edington Heating & Cooling Inc at 937-558-9478.

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 couple of things wrong. These involve:

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

Electrical problems should be checked quickly to stop a fire. If you smell burning plastic when your air conditioner is running, turn it off and reach us at 937-558-9478 right away.

6. Air Conditioner Smells Like Cat Pee

A powerful ammonia odor means there may be mold flourishing within your air conditioner or ductwork. The smell isn’t the mold itself, but the mycotoxins that mold produces.

How to Solve It

Mycotoxins are hazardous to your wellness. That’s why you should have a pro like Edington Heating & Cooling Inc look at your air conditioner and ductwork and clean it when recommended.
