When your air conditioner is spotless and operating properly, you shouldn’t be smelling anything strange. Unusual air conditioner noises and strange smells are a hint that something is out of whack. If your air conditioner is aging or you haven’t had a tune-up done lately, they can be a clear sign you need professional air conditioning repair in Lexington.

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 positive sign. You might also notice your:

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

These sweet, chemical smells are regularly a clue that your air conditioner is suffering from a refrigerant leak. Your system relies on this gas to transfer heat through copper coils, which can crack as time passes.

Four Clues You Are Experiencing 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 runs.
  2. Ice on refrigerant lines or the evaporator coil.
  3. Difficulty keeping your house cold or reaching your desired temperature.
  4. Higher utility bills.

How You Can Fix It

A refrigerant leak needs professional repairs from a heating and cooling company like James Heating & A/C, Inc. Your cooling professional will locate and mend the leak before recharging your AC with refrigerant.

Fixing a refrigerant leak typically costs between $225 and $1,600, according to nationwide averages put together by HomeAdvisor. Your precise cost will depend on the location and severity of the leak, as well as how long it requires to solve.

If your air conditioner was installed before 2010, there’s a good chance it uses R-22 or Freon refrigerant. This refrigerant is no longer being made as a result of its harmful effects on the ozone layer. Because of this, repairs can be significantly expensive so it may be best to schedule air conditioning installation in this instance.

2. Air Conditioner Smells Like Gas

If your air conditioner smells like rotten eggs, there’s possibly nothing wrong with it. But there’s a high 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, because the gas can be toxic in large amounts.

How You Can Fix It

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

  • Switching off your gas supply.
  • Opening windows.
  • Evacuating your home as soon as possible.
  • Getting in touch with your gas company without delay.

3. Air Conditioner Smells Musty

Homeowners who call us regarding this issue often say their air conditioner smells like feet, dirty socks or a locker room when it’s on. Also referred to as dirty sock syndrome, this smell is frequently 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 typical in climates where you turn on heating at night and during the morning before switching to cooling during the afternoon.

How to Fix It

The best way to prevent dirty sock syndrome is to regularly get a new air filter and schedule yearly air conditioning maintenance with James Heating & A/C, Inc. We’ll keep the evaporator coil clean and the drainage system flowing, since excess water can also create nasty odors.

4. Air Conditioner Smells Like Vinegar

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

  • A filthy filter
  • Excess condensation
  • Plugged condensate pan or drain line
  • Moldy air conditioner or ductwork

How to Fix It

Examine your filter first. If you haven’t changed it within the last three months and can’t see light through it, it’s time to replace it. If that doesn’t solve the issue, contact James Heating & A/C, Inc at 336-853-6070.

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 involve:

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

Electrical malfunctions should be checked quickly to stop a fire. If you smell burning plastic when your air conditioner is on, turn it off and contact us at 336-853-6070 right away.

6. Air Conditioner Smells Like Cat Pee

An overpowering ammonia odor means there could be mold spreading in your air conditioner or ductwork. The smell isn’t the mold itself, but the mycotoxins that mold produces.

How to Repair It

Mycotoxins are hazardous to your well-being. That’s why we recommend having a pro like James Heating & A/C, Inc look at your air conditioner and ductwork and clean it when recommended.
