When your air conditioner is fresh and running properly, it’s not normal to be smelling anything odd. Abnormal air conditioner noises and odd smells are a sign that something is out of whack. If your air conditioner is old or you haven’t had maintenance completed within the last year, they can be a clear sign you need professional air conditioning repair in Marshalltown.

Here are six of the top 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 scent, it isn’t a positive sign. You might also report your:

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

These sweet, chemical scents are regularly a sign that your air conditioner is suffering from a refrigerant leak. Your system needs this gas to shift heat through copper coils, which can crack as time passes.

Four clues 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 operating.
  2. Frost on refrigerant lines or the evaporator coil.
  3. Trouble keeping your residence comfortable or having your set temperature.
  4. High utility costs.

How You Can Take Care of It

A refrigerant leak needs experienced assistance from a heating and cooling company like Kapaun & Brown. Your cooling specialist will locate and repair the leak before recharging your system with refrigerant.

Repairing a refrigerant leak often costs between $225 and $1,600, per nationwide averages assembled by HomeAdvisor. Your total cost will depend on the location and severity of the leak, as well as how many hours it requires to fix.

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 because of its adverse effects on the ozone layer. Consequently, repairs can be significantly expensive so it may be best to do air conditioning installation in this circumstance.

2. Air Conditioner Smells Like Gas

If your air conditioner smells like rotten eggs, there’s probably nothing wrong with it. But there’s a high probability you have a natural gas leak in your residence. Natural gas has a sulfur-like additive to alert you when there’s a leak, since the gas can be fatal in large amounts.

How You Can Repair It

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

  • Switching off your gas supply.
  • Opening windows.
  • Leaving your home right away.
  • Calling your gas company now.

3. Air Conditioner Smells Musty

Homeowners who reach us about this situation usually say their air conditioner smells like feet, dirty socks or a locker room when it’s running. Also known as dirty sock syndrome, this smell is usually created by a grubby evaporator coil that has mold, mildew and bacteria buildup. Moisture can also make your home air conditioner smell bad. Dirty sock syndrome is most typical in areas where you use heating at night and during the morning before transitioning to cooling later on.

How to Fix It

The best way to prevent dirty sock syndrome is to routinely replace your air filter and schedule routine air conditioning maintenance with Kapaun & Brown. We’ll keep the evaporator coil clean and the drainage system flowing, since excess water can also produce nasty odors.

4. Air Conditioner Smells Like Vinegar

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

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

How to Fix It

Check 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 solve the smell, contact Kapaun & Brown at 641-812-2028.

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 involve:

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

Electrical problems should be checked quickly to prevent a fire. If you detect burning plastic when your air conditioner is on, switch it off and reach us at 641-812-2028 immediately.

6. Air Conditioner Smells Like Cat Pee

A powerful ammonia odor means there could be mold growing inside your air conditioner or ductwork. The smell isn’t the mold itself, but the mycotoxins that mold produces.

How to Solve It

Mycotoxins are hazardous to your health. That’s why we recommend having a professional like Kapaun & Brown examine your air conditioner and ductwork and clean it when necessary.
