When your air conditioner is clean and operating properly, you shouldn’t be smelling anything weird. Out of the ordinary air conditioner noises and strange smells are a hint that something is up. If your air conditioner is getting older or you haven’t had service scheduled within the last year, they can be a clear sign you need skilled air conditioning repair in Saint Louis.

Here are six of the most common 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 odor, it isn’t a great sign. You could also report your:

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

These sweet, chemical odors are typically a clue that your air conditioner is experiencing a refrigerant leak. Your system relies on this gas to transfer heat through copper coils, which can break out over time.

Four Clues You Are Dealing with a Refrigerant Leak

Aside from the strange smell, here are four other hints that you have a refrigerant leak.

  1. Bubbling or hissing sounds when your air conditioner is on.
  2. Ice on refrigerant lines or the evaporator coil.
  3. It’s hard keeping your residence cold or reaching your programmed temperature.
  4. Increasing utility costs.

How You Can Repair It

A refrigerant leak needs skilled support from a heating and cooling company like Morgner Inc. Air Conditioning & Heating. Your cooling technician will locate and repair the leak before recharging your AC with refrigerant.

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

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 made due to its harmful effects on the ozone layer. Consequently, repairs can be very expensive so it may be best to consider air conditioning installation in this circumstance.

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

How You Can Fix It

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

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

3. Air Conditioner Smells Musty

People who reach us about this situation frequently share their air conditioner smells like feet, dirty socks or a locker room when it’s on. Also referred to as dirty sock syndrome, this smell is frequently caused by a filthy 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 turn on heating at night and during the morning before turning on cooling later on.

How to Solve It

The best approach for preventing dirty sock syndrome is to regularly get a new air filter and schedule regular air conditioning maintenance with Morgner Inc. Air Conditioning & Heating. We’ll keep the evaporator coil clean and the drainage system unblocked, because stagnant water can also lead to nasty odors.

4. Air Conditioner Smells Like Vinegar

If you are dealing with air conditioner mildew smell or a pungent, vinegar-like odor, it might be caused by several issues, like:

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

How to Resolve It

Examine your filter first. If you haven’t replaced 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 smell, reach Morgner Inc. Air Conditioning & Heating at 314-262-4541.

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 number of things wrong. These involve:

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

Electrical issues should be checked immediately to stop a fire. If you notice burning plastic when your air conditioner is operating, switch it off and reach us at 314-262-4541 right away.

6. Air Conditioner Smells Like Cat Pee

An overpowering ammonia odor means there may be mold present within your air conditioner or ductwork. The smell isn’t the mold itself, but the mycotoxins that mold creates.

How to Solve It

Mycotoxins are hazardous to your wellness. That’s why you should have a specialist like Morgner Inc. Air Conditioning & Heating look at your air conditioner and ductwork and clean it when necessary.
