When your air conditioner is fresh and operating properly, it’s expected you won’t be smelling anything strange. Peculiar air conditioner noises and odd smells are a hint that something is out of whack. If your air conditioner is aging or you haven’t had maintenance scheduled within the last year, they can be a sure sign you need skilled air conditioning repair in Norco and St. Charles Parish.

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, particularly a chemical odor, it isn’t a good sign. You could also observe 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 experiencing a refrigerant leak. Your system relies on this gas to transfer heat through copper coils, which can crack over time.

Four hints you are dealing with a refrigerant leak.

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

  1. Bubbling or hissing sounds when your air conditioner runs.
  2. Ice crystals on refrigerant lines or the evaporator coil.
  3. Trouble keeping your home cold or having your desired temperature.
  4. Increasing electrical bills.

How You Can Repair It

A refrigerant leak requires experienced repairs from a heating and cooling company like Mayeuxs AC & Heating. Your cooling pro will locate and repair the leak before recharging your air conditioner with refrigerant.

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

If your air conditioner was installed before 2010, it’s likely it uses 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 consequence, 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 probably nothing wrong with it. But there’s a high likelihood 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 big amounts.

How You Can Repair It

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

  • Turning off your gas supply.
  • Opening windows.
  • Evacuating your home as soon as possible.
  • Calling your gas company without delay.

3. Air Conditioner Smells Musty

Individuals who call us regarding this situation usually share their air conditioner smells like feet, dirty socks or a locker room when it’s running. Also called dirty sock syndrome, this smell is typically caused by a dirty 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 areas where you need heating at night and during the morning before transitioning to cooling later in the day.

How to Fix It

The best way to prevent dirty sock syndrome is to regularly replace your air filter and schedule annual air conditioning maintenance with Mayeuxs AC & Heating. We’ll keep the evaporator coil clean and the drainage system flowing, because stagnant water can also create unpleasant odors.

4. Air Conditioner Smells Like Vinegar

If you are experiencing air conditioner mildew smell or a strong, vinegar-like odor, it can be caused by several problems, such as:

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

How to Repair It

Inspect your filter first. If you haven’t put in a new one within the last three months and can’t see light through it, you should replace it. If that doesn’t resolve the problem, contact Mayeuxs AC & Heating at (985) 764-2426.

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 issue.

Electrical issues should be checked immediately to stop a fire. If you detect burning plastic when your air conditioner is on, turn it off and reach us at (985) 764-2426 right away.

6. Air Conditioner Smells Like Cat Pee

An overpowering ammonia odor means there could be mold growing inside 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 we recommend having a professional like Mayeuxs AC & Heating check your air conditioner and ductwork and clean it when needed.
