When your air conditioner is fresh and running right, you shouldn’t be smelling anything weird. Abnormal air conditioner noises and strange smells are a clue that something is out of whack. If your air conditioner is getting older or you haven’t had maintenance done recently, they can be a clear sign you need skilled air conditioning repair in Huntsville.

Here are six of the most frequent air conditioner smells and how you can resolve 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 observe your:

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

These sweet, chemical smells are typically a hint that your air conditioner has a refrigerant leak. Your system needs this gas to shift heat through copper coils, which can wear out as time passes.

Four Hints You Are Experiencing a Refrigerant Leak

Besides the odd smell, here are four other signs that you are dealing with a refrigerant leak.

  1. Bubbling or hissing sounds when your air conditioner is cooling.
  2. Ice crystals on refrigerant lines or the evaporator coil.
  3. It’s hard keeping your house cool or achieving your programmed temperature.
  4. Higher energy bills.

How You Can Repair It

A refrigerant leak calls for professional assistance from a heating and cooling company like All Weather Heating & Air Conditioning Inc. Your cooling specialist will locate and repair the leak before recharging your system with refrigerant.

Fixing a refrigerant leak typically costs between $225 and $1,600, based on nationwide averages compiled by HomeAdvisor. Your exact 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 earlier than 2010, there’s a high probability it has R-22 or Freon refrigerant. This refrigerant is no longer being produced because of its harmful effects on the ozone layer. As a result, 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 possibly nothing wrong with it. But there’s a high probability you have a natural gas leak in your home. Natural gas has a sulfur-like additive to signal you when there’s a leak, since the gas can be deadly in heavy concentrations.

How You Can Fix It

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

  • Switching off your gas supply.
  • Opening windows.
  • Leaving your home as soon as possible.
  • Contacting your gas company immediately.

3. Air Conditioner Smells Musty

Homeowners who contact us to report this problem usually report their air conditioner smells like feet, dirty socks or a locker room when it’s running. Also called dirty sock syndrome, this smell is often 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 climates where you use heating at night and during the morning before transitioning to cooling later on.

How to Repair It

The best approach for preventing dirty sock syndrome is to routinely change your air filter and schedule routine air conditioning maintenance with All Weather Heating & Air Conditioning Inc. We’ll keep the evaporator coil clean and the drainage system flowing, because stagnant water can also create noxious odors.

4. Air Conditioner Smells Like Vinegar

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

  • A dirty filter
  • Too much 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, we recommend replacing it. If that doesn’t fix the problem, contact All Weather Heating & Air Conditioning Inc at 256-801-4701.

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 number of things wrong. These entail:

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

Electrical malfunctions should be examined right away to prevent a fire. If you notice burning plastic when your air conditioner is running, switch it off and reach us at 256-801-4701 without delay.

6. Air Conditioner Smells Like Cat Pee

A powerful 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 produces.

How to Repair It

Mycotoxins are hazardous to your wellness. That’s why it’s important to have a professional like All Weather Heating & Air Conditioning Inc examine your air conditioner and ductwork and clean it when recommended.
