When your air conditioner is clean and operating properly, it’s expected you won’t be smelling anything strange. Unusual air conditioner noises and weird smells are a sign that something is out of whack. If your air conditioner is past its prime or you haven’t had service completed recently, they can be a clear sign you need professional air conditioning repair in Alliance.

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, especially a chemical scent, it isn’t a good sign. You could also notice your:

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

These sweet, chemical smells are typically a hint that your air conditioner has a refrigerant leak. Your system uses this gas to transfer heat through copper coils, which can break out as time passes.

Four Hints You Have a Refrigerant Leak

Besides the odd smell, here are four other clues that you have a refrigerant leak.

  1. Bubbling or hissing sounds when your air conditioner is cooling.
  2. Ice on refrigerant lines or the evaporator coil.
  3. It’s hard keeping your home cool or reaching your desired temperature.
  4. Higher energy bills.

How You Can Fix It

A refrigerant leak calls for skilled support from a heating and cooling company like Jack's Heating, Cooling, Stoves & Fireplaces. Your cooling specialist will pinpoint and repair the leak before recharging your AC with refrigerant.

Repairing a refrigerant leak often costs between $225 and $1,600, per nationwide averages put together by HomeAdvisor. Your total cost will depend on the location and severity of the leak, as well as how much time it requires to fix.

If your air conditioner was installed before 2010, it’s likely it uses R-22 or Freon refrigerant. This refrigerant is no longer being produced because of its damaging effects on the ozone layer. As a result, repairs can be very expensive so it may be smartest to schedule air conditioning installation in this instance.

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 probability you have a natural gas leak in your house. Natural gas has a sulfur-like additive to signal you when there’s a leak, as the gas can be deadly in heavy concentrations.

How You Can Solve It

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

  • Shutting off your gas supply.
  • Opening windows.
  • Leaving your home right away.
  • Getting in touch with your gas company immediately.

3. Air Conditioner Smells Musty

Individuals who contact us about this situation often report their air conditioner smells like feet, dirty socks or a locker room when it runs. Also known as dirty sock syndrome, this smell is usually linked to a filthy evaporator coil that has mold, mildew and bacteria buildup. Excess water can also make your home air conditioner smell bad. Dirty sock syndrome is most common in locations where you turn on heating at night and during the morning before transitioning to cooling later on.

How to Fix It

The best approach for preventing dirty sock syndrome is to frequently replace your air filter and schedule regular air conditioning maintenance with Jack's Heating, Cooling, Stoves & Fireplaces. We’ll keep the evaporator coil clean and the drainage system unblocked, as excess water can also result in unpleasant odors.

4. Air Conditioner Smells Like Vinegar

If you are experiencing air conditioner mildew smell or a strong, vinegar-like odor, it might be caused by several issues, like:

  • A clogged filter
  • Too much condensation
  • Clogged condensate pan or drain line
  • Moldy air conditioner or ductwork

How to Fix It

Check your filter first. If you haven’t changed it within the last three months and can’t see light through it, you should replace it. If that doesn’t solve the smell, reach Jack's Heating, Cooling, Stoves & Fireplaces at 308-762-1613.

5. Air Conditioner Smells Like Burning Plastic

If you’re experiencing an air conditioner burning smell or that your air conditioner smells like fish, there could be a couple of things wrong. These include:

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

Electrical issues should be inspected quickly to stop a fire. If you detect burning plastic when your air conditioner is on, shut it off and contact us at 308-762-1613 immediately.

6. Air Conditioner Smells Like Cat Pee

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

How to Repair It

Mycotoxins are hazardous to your well-being. That’s why we recommend having a pro like Jack's Heating, Cooling, Stoves & Fireplaces examine your air conditioner and ductwork and clean it when necessary.
