When your air conditioner is clean and operating right, you shouldn’t be smelling anything weird. Abnormal air conditioner noises and weird smells are a sign that something is out of whack. If your air conditioner is old or you haven’t had service scheduled recently, they can be a clear sign you need professional air conditioning repair in Manassas.

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, specifically a chemical odor, it isn’t a good sign. You may also observe your:

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

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

Four hints you have a refrigerant leak.

Aside from the strange smell, here are four other clues 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 house cold or reaching your set temperature.
  4. Higher electrical bills.

How You Can Repair It

A refrigerant leak calls for experienced support from a heating and cooling company like Fire & Ice HVAC. Your cooling professional will pinpoint and mend the leak before recharging your air conditioner with refrigerant.

Resolving a refrigerant leak often costs between $225 and $1,600, according to nationwide averages compiled by HomeAdvisor. Your total 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 prior to 2010, there’s a good chance it has R-22 or Freon refrigerant. This refrigerant is no longer being manufactured due to its adverse effects on the ozone layer. Consequently, repairs can be very expensive so it may be wisest to consider 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 likelihood you have a natural gas leak in your house. Natural gas has a sulfur-like additive to warn you when there’s a leak, since the gas can be deadly in big amounts.

How You Can Fix It

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

  • Switching off your gas supply.
  • Opening windows.
  • Leaving your home promptly.
  • Getting in touch with your gas company without delay.

3. Air Conditioner Smells Musty

People who contact us about this problem frequently say their air conditioner smells like feet, dirty socks or a locker room when it runs. Also referred to as dirty sock syndrome, this smell is frequently linked to a dirty evaporator coil that has mold, mildew and bacteria buildup. Moisture 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 later in the day.

How to Repair It

The best way to prevent dirty sock syndrome is to routinely change your air filter and schedule annual air conditioning maintenance with Fire & Ice HVAC. We’ll keep the evaporator coil clean and the drainage system flowing, since standing water can also result in unpleasant odors.

4. Air Conditioner Smells Like Vinegar

If you are living with air conditioner mildew smell or an acidic, vinegar-like odor, it might be prompted by several issues, like:

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

How to Resolve It

Examine your filter first. If you haven’t put in a new one within the last three months and can’t see light through it, it’s time to replace it. If that doesn’t fix the problem, contact Fire & Ice HVAC at 703-595-4157.

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 involve:

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

Electrical issues should be examined immediately to stop a fire. If you smell burning plastic when your air conditioner is running, turn it off and call us at 703-595-4157 right away.

6. Air Conditioner Smells Like Cat Pee

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

How to Solve It

Mycotoxins are hazardous to your well-being. That’s why you should have a specialist like Fire & Ice HVAC look at your air conditioner and ductwork and clean it when recommended.
