When your air conditioner is spotless and working properly, it’s not normal to be smelling anything strange. Unexpected air conditioner noises and weird smells are a sign that something is up. If your air conditioner is aging or you haven’t had a tune-up completed within the last year, they can be a sure sign you need pro air conditioning repair in Phoenix.

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

1. Central Air Conditioner Smells Like Chemicals

If your air conditioner smells bad when turned on, especially a chemical scent, 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 often a hint that your air conditioner is experiencing a refrigerant leak. Your system needs this gas to transfer heat through copper coils, which can wear out as time passes.

Four Clues You Have a Refrigerant Leak

Besides 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 is on.
  2. Ice crystals on refrigerant lines or the evaporator coil.
  3. It’s hard keeping your home cool or reaching your programmed temperature.
  4. Increasing utility costs.

How You Can Repair It

A refrigerant leak requires professional support from a heating and cooling company like Integrity AC & Heating LLC. Your cooling pro will find and fix the leak before recharging your system with refrigerant.

Fixing 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 long it requires to repair.

If your air conditioner was installed earlier than 2010, there’s a high probability it uses R-22 or Freon refrigerant. This refrigerant is no longer being produced because of its harmful effects on the ozone layer. Due to this, repairs can be very expensive so it may be smartest to schedule air conditioning installation in this instance.

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 high probability you have a natural gas leak in your residence. Natural gas has a sulfur-like additive to alert you when there’s a leak, since the gas can be fatal in large amounts.

How You Can Repair It

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

  • Shutting off your gas supply.
  • Opening windows.
  • Going outside promptly.
  • Getting in touch with your gas company immediately.

3. Air Conditioner Smells Musty

Homeowners who call us regarding this situation often report their air conditioner smells like feet, dirty socks or a locker room when it runs. Also called dirty sock syndrome, this smell is often created by a dirty evaporator coil that has mold, mildew and bacteria buildup. Excess water can also make your home air conditioner smell bad. Dirty sock syndrome is most common in climates where you turn on heating at night and during the morning before turning on cooling later on.

How to Solve It

The best way to prevent dirty sock syndrome is to regularly get a new air filter and schedule routine air conditioning maintenance with Integrity AC & Heating LLC. 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 experiencing air conditioner mildew smell or a strong, vinegar-like odor, it could be caused by several problems, like:

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

How to Repair It

Check 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 solve the issue, contact Integrity AC & Heating LLC at 602-971-0567.

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 couple of things wrong. These include:

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

Electrical issues should be inspected immediately to prevent a fire. If you notice burning plastic when your air conditioner is running, shut it off and reach us at 602-971-0567 right away.

6. Air Conditioner Smells Like Cat Pee

A strong ammonia odor means there may be mold flourishing 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 pro like Integrity AC & Heating LLC check your air conditioner and ductwork and clean it when recommended.
