When your air conditioner is spotless and operating properly, it’s expected you won’t be smelling anything strange. Peculiar air conditioner noises and odd smells are a clue that something is off. If your air conditioner is old or you haven’t had maintenance completed lately, they can be a clear sign you need professional air conditioning repair in Derby.

Here are six of the top 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 odor, it isn’t a positive sign. You could also notice your:

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

These sweet, chemical scents are frequently a clue that your air conditioner has a refrigerant leak. Your system relies on this gas to transfer heat through copper coils, which can break out as time goes on.

Four Signs You Have a Refrigerant Leak

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

  1. Bubbling or hissing sounds when your air conditioner is cooling.
  2. Frost on refrigerant lines or the evaporator coil.
  3. Difficulty keeping your home cold or reaching your set temperature.
  4. High energy expenses.

How You Can Fix It

A refrigerant leak calls for skilled repairs from a heating and cooling company like Giordanos Heating and Air Conditioning. Your cooling pro will locate and fix the leak before recharging your air conditioner with refrigerant.

Repairing a refrigerant leak typically 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 long it requires to solve.

If your air conditioner was installed earlier than 2010, there’s a good chance it uses R-22 or Freon refrigerant. This refrigerant is no longer being manufactured due to its adverse effects on the ozone layer. Because of this, repairs can be very expensive so it may be best to schedule air conditioning installation in this situation.

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 likelihood you have a natural gas leak in your home. Natural gas has a sulfur-like additive to alert you when there’s a leak, because the gas can be deadly in large amounts.

How You Can Solve It

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

  • Turning off your gas supply.
  • Opening windows.
  • Going outside as soon as possible.
  • Contacting your gas company now.

3. Air Conditioner Smells Musty

Individuals who call us regarding this situation usually mention their air conditioner smells like feet, dirty socks or a locker room when it runs. Also called dirty sock syndrome, this smell is frequently created 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 locations where you need heating at night and during the morning before switching to cooling later in the day.

How to Fix It

The best approach for preventing dirty sock syndrome is to regularly get a new air filter and schedule routine air conditioning maintenance with Giordanos Heating and Air Conditioning. We’ll keep the evaporator coil clean and the drainage system unblocked, since standing water can also produce nasty odors.

4. Air Conditioner Smells Like Vinegar

If you are dealing with air conditioner mildew smell or a strong, vinegar-like odor, it might be prompted by several problems, like:

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

How to Resolve It

Check 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 problem, call Giordanos Heating and Air Conditioning at 203-772-8319.

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 number of things wrong. These entail:

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

Electrical malfunctions should be examined right away to avoid a fire. If you detect burning plastic when your air conditioner is running, turn it off and call us at 203-772-8319 immediately.

6. Air Conditioner Smells Like Cat Pee

A powerful ammonia odor means there might be mold growing in 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 wellness. That’s why you should have a professional like Giordanos Heating and Air Conditioning look at your air conditioner and ductwork and clean it when necessary.
