When your air conditioner is fresh and operating properly, it’s not normal to be smelling anything odd. 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 maintenance done lately, they can be a sure sign you need skilled air conditioning repair in Lansing.

Here are six of the most frequent 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, especially a chemical smell, it isn’t a great sign. You might also observe your:

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

These sweet, chemical smells are often a hint that your air conditioner is experiencing a refrigerant leak. Your system needs this gas to move heat through copper coils, which can crack over time.

Four clues you are experiencing a refrigerant leak.

Besides the odd smell, here are four other signs that you are dealing with a refrigerant leak.

  1. Bubbling or hissing sounds when your air conditioner runs.
  2. Frost on refrigerant lines or the evaporator coil.
  3. Difficulty keeping your home cool or reaching your programmed temperature.
  4. Higher utility bills.

How You Can Take Care of It

A refrigerant leak calls for experienced repairs from a heating and cooling company like Everest Heating & Cooling. Your cooling technician will pinpoint and mend the leak before recharging your AC with refrigerant.

Repairing a refrigerant leak often 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 needs to solve.

If your air conditioner was installed prior to 2010, there’s a high probability it has R-22 or Freon refrigerant. This refrigerant is no longer being produced as a result of its damaging effects on the ozone layer. As a result, repairs can be significantly expensive so it may be wisest to do air conditioning installation in this circumstance.

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 good 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, as the gas can be fatal in large amounts.

How You Can Fix It

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

  • Shutting off your gas supply.
  • Opening windows.
  • Going outside promptly.
  • Contacting your gas company immediately.

3. Air Conditioner Smells Musty

Homeowners who reach us about this problem often mention their air conditioner smells like feet, dirty socks or a locker room when it runs. Also known as dirty sock syndrome, this smell is often created by a grubby evaporator coil that has mold, mildew and bacteria buildup. Moisture can also make your home air conditioner smell bad. Dirty sock syndrome is most often seen in locations where you use heating at night and during the morning before transitioning to cooling later in the day.

How to Fix It

The best approach for preventing dirty sock syndrome is to regularly change your air filter and schedule regular air conditioning maintenance with Everest Heating & Cooling. We’ll keep the evaporator coil clean and the drainage system unclogged, since stagnant water can also result in noxious odors.

4. Air Conditioner Smells Like Vinegar

If you are dealing with air conditioner mildew smell or a pungent, vinegar-like odor, it could be the result of several issues, such as:

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

How to Solve It

Examine 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 issue, reach Everest Heating & Cooling at 913-845-9463.

5. Air Conditioner Smells Like Burning Plastic

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

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

Electrical problems should be inspected quickly to prevent a fire. If you notice burning plastic when your air conditioner is running, turn it off and contact us at 913-845-9463 immediately.

6. Air Conditioner Smells Like Cat Pee

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

How to Fix It

Mycotoxins are hazardous to your well-being. That’s why it’s important to have a professional like Everest Heating & Cooling check your air conditioner and ductwork and clean it when needed.
