When your air conditioner is fresh and working right, it’s not normal to be smelling anything weird. Unexpected air conditioner noises and weird smells are a hint that something is off. If your air conditioner is past its prime or you haven’t had a tune-up completed lately, they can be a sure sign you need professional air conditioning repair in Sacramento.

Here are six of the most common 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 good sign. You may also report 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 needs this gas to transfer heat through copper coils, which can wear out over time.

Four hints you are dealing with a refrigerant leak.

In addition to 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 runs.
  2. Frost on refrigerant lines or the evaporator coil.
  3. Difficulty keeping your home cold or reaching your set temperature.
  4. Higher energy expenses.

How You Can Take Care of It

A refrigerant leak calls for professional repairs from a heating and cooling company like Bishop’s HVAC. Your cooling pro will pinpoint and mend the leak before recharging your system with refrigerant.

Resolving a refrigerant leak typically costs between $225 and $1,600, according to nationwide averages put together by HomeAdvisor. Your total cost will depend on the location and severity of the leak, as well as how long it requires to fix.

If your air conditioner was installed early than 2010, there’s a high probability it runs on R-22 or Freon refrigerant. This refrigerant is no longer being made due to its damaging effects on the ozone layer. As a result, repairs can be significantly 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 likely nothing wrong with it. But there’s a significant probability you have a natural gas leak in your residence. Natural gas has a sulfur-like additive to signal you when there’s a leak, since the gas can be toxic in big amounts.

How You Can Fix It

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

  • Shutting off your gas supply.
  • Opening windows.
  • Going outside right away.
  • Contacting your gas company without delay.

3. Air Conditioner Smells Musty

Individuals who call us regarding this problem 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 often linked to 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 often seen in areas where you use heating at night and during the morning before switching to cooling later in the day.

How to Repair It

The best approach for preventing dirty sock syndrome is to routinely replace your air filter and schedule routine air conditioning maintenance with Bishop’s HVAC. We’ll keep the evaporator coil clean and the drainage system unclogged, as excess water can also result in noxious odors.

4. Air Conditioner Smells Like Vinegar

If you are living with air conditioner mildew smell or a pungent, vinegar-like odor, it might be the result of several issues, such as:

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

How to Solve It

Inspect 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 solve the issue, reach Bishop’s HVAC at 916-591-6889.

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 several things wrong. These involve:

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

Electrical issues should be examined quickly to stop a fire. If you smell burning plastic when your air conditioner is operating, turn it off and call us at 916-591-6889 right away.

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 Repair It

Mycotoxins are hazardous to your well-being. That’s why it’s important to have a specialist like Bishop’s HVAC examine your air conditioner and ductwork and clean it when necessary.
