When your air conditioner is spotless and running right, it’s expected you won’t be smelling anything weird. Unexpected air conditioner noises and strange smells are a clue that something is up. If your air conditioner is past its prime or you haven’t had a tune-up scheduled within the last year, they can be an obvious sign you need skilled air conditioning repair in Huntsville.

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, specifically a chemical scent, it isn’t a good sign. You may also observe your:

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

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

Four hints you are dealing with a refrigerant leak.

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

  1. Bubbling or hissing sounds when your air conditioner runs.
  2. Ice on refrigerant lines or the evaporator coil.
  3. It’s hard keeping your residence cool or reaching your programmed temperature.
  4. Higher electrical costs.

How You Can Fix It

A refrigerant leak requires experienced assistance from a heating and cooling company like All Weather Heating & Air Conditioning Inc. Your cooling professional will pinpoint 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 put together by HomeAdvisor. Your total cost will depend on the location and severity of the leak, as well as how many hours it needs to solve.

If your air conditioner was installed before 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. As a result, repairs can be extremely expensive so it may be wisest to consider 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 significant likelihood you have a natural gas leak in your house. Natural gas has a sulfur-like additive to signal you when there’s a leak, as the gas can be fatal in heavy concentrations.

How You Can Fix It

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

  • Switching off your gas supply.
  • Opening windows.
  • Evacuating your home as soon as possible.
  • Contacting your gas company without delay.

3. Air Conditioner Smells Musty

People who reach us regarding this situation usually mention their air conditioner smells like feet, dirty socks or a locker room when it runs. Also referred to as dirty sock syndrome, this smell is usually created by a filthy 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 typical in locations where you turn on heating at night and during the morning before transitioning to cooling during the afternoon.

How to Fix It

The best method for preventing dirty sock syndrome is to routinely change your air filter and schedule yearly air conditioning maintenance with All Weather Heating & Air Conditioning Inc. We’ll keep the evaporator coil clean and the drainage system unblocked, as excess water can also result in 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 issues, including:

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

How to Repair It

Inspect your filter first. If you haven’t put in a new one within the last three months and can’t see light through it, you should replace it. If that doesn’t fix the issue, call 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 needs lubrication.
  • Broken fan belt.
  • Electrical problem.

Electrical malfunctions should be inspected right away to prevent a fire. If you notice burning plastic when your air conditioner is running, shut it off and call us at 256-801-4701 right away.

6. Air Conditioner Smells Like Cat Pee

A powerful ammonia odor means there may be mold present inside 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 well-being. That’s why we recommend having a professional like All Weather Heating & Air Conditioning Inc check your air conditioner and ductwork and clean it when needed.
