When your air conditioner is fresh and working properly, it’s not normal to be smelling anything weird. Unusual air conditioner noises and strange smells are a clue that something is up. If your air conditioner is aging or you haven’t had a tune-up completed within the last year, they can be a sure sign you need professional air conditioning repair in Omaha.

Here are six of the most common 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, specifically a chemical smell, it isn’t a positive sign. You could also notice your:

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

These sweet, chemical scents are frequently a hint that your air conditioner is experiencing a refrigerant leak. Your system uses this gas to move heat through copper coils, which can wear out over time.

Four clues you have a refrigerant leak.

Besides the strange smell, here are four other clues that you are experiencing 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 residence cold or reaching your set temperature.
  4. Increasing electrical costs.

How You Can Take Care of It

A refrigerant leak calls for experienced assistance from a heating and cooling company like Interstate Heating & Air Conditioning. Your cooling technician will locate and mend the leak before recharging your system with refrigerant.

Resolving a refrigerant leak typically costs between $225 and $1,600, based on nationwide averages put together by HomeAdvisor. Your precise cost will depend on the location and severity of the leak, as well as how much time it requires to repair.

If your air conditioner was installed early than 2010, there’s a good chance it uses R-22 or Freon refrigerant. This refrigerant is no longer being manufactured because of its damaging effects on the ozone layer. As a result, repairs can be extremely expensive so it may be smartest to consider air conditioning installation in this instance.

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 chance you have a natural gas leak in your house. Natural gas has a sulfur-like additive to alert you when there’s a leak, since the gas can be fatal in large amounts.

How You Can Solve It

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

  • Turning off your gas supply.
  • Opening windows.
  • Going outside as soon as possible.
  • Getting in touch with your gas company without delay.

3. Air Conditioner Smells Musty

Homeowners who contact us about this situation usually share their air conditioner smells like feet, dirty socks or a locker room when it runs. Also known as dirty sock syndrome, this smell is frequently caused by a dirty 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 often seen in climates where you use heating at night and during the morning before switching to cooling during the afternoon.

How to Solve It

The best approach for preventing dirty sock syndrome is to regularly get a new air filter and schedule yearly air conditioning maintenance with Interstate Heating & Air Conditioning. We’ll keep the evaporator coil clean and the drainage system unclogged, as stagnant water can also produce noxious odors.

4. Air Conditioner Smells Like Vinegar

If you are dealing with air conditioner mildew smell or a strong, vinegar-like odor, it might be caused by several situations, including:

  • A filthy filter
  • Too much condensation
  • Plugged 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, we recommend replacing it. If that doesn’t fix the problem, call Interstate Heating & Air Conditioning at 402-509-5940.

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 include:

  • Broken capacitator that’s overheating the motor.
  • Motor that should have lubrication.
  • Broken fan belt.
  • Electrical trouble.

Electrical problems should be checked immediately to avoid a fire. If you smell burning plastic when your air conditioner is operating, turn it off and reach us at 402-509-5940 without delay.

6. Air Conditioner Smells Like Cat Pee

An overpowering ammonia odor means there may be mold spreading inside 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 you should have a professional like Interstate Heating & Air Conditioning check your air conditioner and ductwork and clean it when recommended.
