When your air conditioner is fresh and working properly, it’s not normal to be smelling anything weird. Abnormal air conditioner noises and odd smells are a sign that something is wrong. If your air conditioner is getting older or you haven’t had a tune-up done within the last year, they can be a clear sign you need professional air conditioning repair in Bloomfield.

Here are six of the most frequent 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, particularly a chemical smell, it isn’t a positive sign. You may also observe your:

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

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

Four Clues You Have a Refrigerant Leak

Aside from the strange smell, here are four other clues that you are experiencing 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 residence cold or achieving your desired temperature.
  4. Higher utility costs.

How You Can Take Care of It

A refrigerant leak needs experienced support from a heating and cooling company like Stanford Heating & Cooling. Your cooling pro will locate and repair the leak before recharging your AC with refrigerant.

Repairing a refrigerant leak often costs between $225 and $1,600, based on nationwide averages compiled by HomeAdvisor. Your precise cost will depend on the location and severity of the leak, as well as how much time it needs to fix.

If your air conditioner was installed prior to 2010, there’s a high probability it runs on R-22 or Freon refrigerant. This refrigerant is no longer being produced as a result of its damaging effects on the ozone layer. Due to this, repairs can be very expensive so it may be best to do air conditioning installation in this situation.

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

How You Can Repair It

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

  • Switching off your gas supply.
  • Opening windows.
  • Evacuating your home right away.
  • Calling your gas company without delay.

3. Air Conditioner Smells Musty

Individuals who contact us to report this problem usually say their air conditioner smells like feet, dirty socks or a locker room when it runs. Also known as dirty sock syndrome, this smell is usually caused 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 turn on heating at night and during the morning before transitioning to cooling during the afternoon.

How to Repair It

The best way to prevent dirty sock syndrome is to routinely change your air filter and schedule routine air conditioning maintenance with Stanford Heating & Cooling. We’ll keep the evaporator coil clean and the drainage system unblocked, because standing water can also create noxious 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 issues, like:

  • A clogged filter
  • Extra condensation
  • Clogged condensate pan or drain line
  • Moldy air conditioner or ductwork

How to Repair 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 fix the problem, contact Stanford Heating & Cooling at 812-825-8695.

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 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 right away to stop a fire. If you notice burning plastic when your air conditioner is running, turn it off and call us at 812-825-8695 without delay.

6. Air Conditioner Smells Like Cat Pee

A powerful ammonia odor means there may be mold growing 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 health. That’s why it’s important to have a professional like Stanford Heating & Cooling examine your air conditioner and ductwork and clean it when recommended.
