When your air conditioner is spotless and operating properly, it’s expected you won’t be smelling anything strange. Unusual air conditioner noises and odd smells are a sign that something is off. If your air conditioner is aging or you haven’t had a tune-up done within the last year, they can be a clear sign you need pro air conditioning repair in Santa Clarita.

Here are six of the most frequent air conditioner smells and how you can solve them.

1. Central Air Conditioner Smells Like Chemicals

If your air conditioner smells bad when turned on, particularly a chemical smell, it isn’t a great sign. You might also notice your:

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

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

Four Clues You Are Dealing with a Refrigerant Leak

Besides 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. Trouble keeping your home comfortable or achieving your desired temperature.
  4. Higher energy expenses.

How You Can Take Care of It

A refrigerant leak calls for experienced repairs from a heating and cooling company like Verona HVAC. Your cooling pro will locate and repair the leak before recharging your air conditioner with refrigerant.

Repairing a refrigerant leak typically 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 needs to solve.

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

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 significant chance you have a natural gas leak in your house. Natural gas has a sulfur-like additive to warn you when there’s a leak, because the gas can be toxic in heavy concentrations.

How You Can Repair It

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

  • Turning off your gas supply.
  • Opening windows.
  • Evacuating your home as soon as possible.
  • Getting in touch with your gas company immediately.

3. Air Conditioner Smells Musty

Homeowners who contact us to report this problem often report 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 often created by 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 common in locations where you need heating at night and during the morning before turning on cooling later in the day.

How to Repair It

The best approach for preventing dirty sock syndrome is to frequently replace your air filter and schedule regular air conditioning maintenance with Verona HVAC. We’ll keep the evaporator coil clean and the drainage system unblocked, as excess water can also lead to unpleasant odors.

4. Air Conditioner Smells Like Vinegar

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

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

How to Solve It

Check your filter first. If you haven’t replaced it within the last three months and can’t see light through it, you should replace it. If that doesn’t resolve the smell, reach Verona HVAC at 818-306-3387.

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 several things wrong. These involve:

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

Electrical issues should be inspected right away to prevent a fire. If you smell burning plastic when your air conditioner is on, switch it off and reach us at 818-306-3387 immediately.

6. Air Conditioner Smells Like Cat Pee

An overpowering ammonia odor means there could 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 health. That’s why it’s important to have a specialist like Verona HVAC examine your air conditioner and ductwork and clean it when recommended.
