When your air conditioner is spotless and operating right, you shouldn’t be smelling anything odd. Peculiar air conditioner noises and odd smells are a sign that something is off. If your air conditioner is aging or you haven’t had maintenance completed within the last year, they can be an obvious sign you need skilled air conditioning repair in Holbrook.

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, especially a chemical smell, it isn’t a great sign. You may also report your:

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

These sweet, chemical odors are regularly a clue that your air conditioner is experiencing a refrigerant leak. Your system relies on this gas to move heat through copper coils, which can crack as time passes.

Four Signs You Have 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 runs.
  2. Frost on refrigerant lines or the evaporator coil.
  3. It’s hard keeping your residence cold or having your set temperature.
  4. Higher utility bills.

How You Can Fix It

A refrigerant leak needs skilled assistance from a heating and cooling company like Fal-Ken Heating & Cooling Corporation. Your cooling specialist will find 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 much time it requires to repair.

If your air conditioner was installed before 2010, there’s a high probability it has R-22 or Freon refrigerant. This refrigerant is no longer being made because of its adverse effects on the ozone layer. Because of this, 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 likely nothing wrong with it. But there’s a significant chance you have a natural gas leak in your residence. Natural gas has a sulfur-like additive to warn you when there’s a leak, since the gas can be fatal in large amounts.

How You Can Repair It

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

  • Switching off your gas supply.
  • Opening windows.
  • Leaving your home promptly.
  • Contacting your gas company now.

3. Air Conditioner Smells Musty

People who reach us regarding this problem often say their air conditioner smells like feet, dirty socks or a locker room when it’s running. Also referred to as dirty sock syndrome, this smell is often linked to 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 locations where you need heating at night and during the morning before turning on cooling later in the day.

How to Fix It

The best way to prevent dirty sock syndrome is to regularly change your air filter and schedule regular air conditioning maintenance with Fal-Ken Heating & Cooling Corporation. We’ll keep the evaporator coil clean and the drainage system unblocked, since excess water can also lead to nasty odors.

4. Air Conditioner Smells Like Vinegar

If you are living with air conditioner mildew smell or an acidic, vinegar-like odor, it can be prompted by several situations, such as:

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

How to Fix 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 resolve the issue, reach Fal-Ken Heating & Cooling Corporation at 631-460-5159.

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 couple of things wrong. These entail:

  • Broken capacitator that’s overheating the motor.
  • Motor that needs lubrication.
  • Broken fan belt.
  • Electrical trouble.

Electrical issues should be examined immediately to stop a fire. If you notice burning plastic when your air conditioner is on, switch it off and call us at 631-460-5159 right away.

6. Air Conditioner Smells Like Cat Pee

An overpowering 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 makes.

How to Fix It

Mycotoxins are hazardous to your well-being. That’s why we recommend having a professional like Fal-Ken Heating & Cooling Corporation look at your air conditioner and ductwork and clean it when recommended.
