When your air conditioner is spotless and running properly, it’s not normal to be smelling anything odd. Out of the ordinary air conditioner noises and weird smells are a hint that something is wrong. If your air conditioner is aging or you haven’t had service completed within the last year, they can be a clear sign you need skilled air conditioning repair in Norton.

Here are six of the most common air conditioner smells and how you can repair 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 great sign. You may also notice your:

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

These sweet, chemical smells are frequently a hint that your air conditioner is suffering from a refrigerant leak. Your system relies on this gas to move heat through copper coils, which can wear out as time goes on.

Four Hints You Are Experiencing a Refrigerant Leak

In addition to the weird smell, here are four other signs that you are experiencing a refrigerant leak.

  1. Bubbling or hissing sounds when your air conditioner is on.
  2. Frost on refrigerant lines or the evaporator coil.
  3. It’s hard keeping your house cool or having your programmed temperature.
  4. Higher energy bills.

How You Can Fix It

A refrigerant leak needs professional assistance from a heating and cooling company like HCE Systems. Your cooling technician will pinpoint and repair the leak before recharging your system with refrigerant.

Repairing a refrigerant leak often costs between $225 and $1,600, according to nationwide averages assembled by HomeAdvisor. Your exact cost will depend on the location and severity of the leak, as well as how long it requires to fix.

If your air conditioner was installed prior to 2010, it’s likely it runs on R-22 or Freon refrigerant. This refrigerant is no longer being manufactured because of its negative effects on the ozone layer. Due to this, repairs can be extremely expensive so it may be best to schedule air conditioning installation in this circumstance.

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 residence. Natural gas has a sulfur-like additive to signal you when there’s a leak, because the gas can be fatal in heavy concentrations.

How You Can Repair It

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

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

3. Air Conditioner Smells Musty

Homeowners who call us regarding this situation often say their air conditioner smells like feet, dirty socks or a locker room when it’s running. Also referred to as dirty sock syndrome, this smell is typically 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 locations where you use heating at night and during the morning before switching to cooling during the afternoon.

How to Repair It

The best way to prevent dirty sock syndrome is to regularly replace your air filter and schedule yearly air conditioning maintenance with HCE Systems. We’ll keep the evaporator coil clean and the drainage system flowing, since stagnant water can also produce unpleasant odors.

4. Air Conditioner Smells Like Vinegar

If you are living with air conditioner mildew smell or a strong, vinegar-like odor, it could be caused by several problems, including:

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

How to Solve 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 fix the issue, contact HCE Systems at 276-302-0076.

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 number of things wrong. These entail:

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

Electrical issues should be checked quickly to avoid a fire. If you detect burning plastic when your air conditioner is operating, turn it off and contact us at 276-302-0076 right away.

6. Air Conditioner Smells Like Cat Pee

A strong 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 specialist like HCE Systems examine your air conditioner and ductwork and clean it when needed.
