When your air conditioner is clean and running correctly, you shouldn’t be smelling anything odd. Unusual air conditioner noises and weird smells are a hint that something is out of whack. If your air conditioner is aging or you haven’t had maintenance scheduled within the last year, they can be a sure sign you need professional air conditioning repair in Pella.

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, especially a chemical scent, it isn’t a great sign. You may also notice 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 uses this gas to move heat through copper coils, which can crack as time passes.

Four Signs You Are Dealing with a Refrigerant Leak

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

  1. Bubbling or hissing sounds when your air conditioner is on.
  2. Frost on refrigerant lines or the evaporator coil.
  3. Difficulty keeping your residence cool or reaching your desired temperature.
  4. Higher energy bills.

How You Can Fix It

A refrigerant leak calls for professional repairs from a heating and cooling company like Van Haaften Plumbing & Heating. Your cooling professional will find and repair the leak before recharging your AC with refrigerant.

Fixing a refrigerant leak often costs between $225 and $1,600, per nationwide averages assembled by HomeAdvisor. Your precise cost will depend on the location and severity of the leak, as well as how much time it requires to solve.

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 due to its damaging effects on the ozone layer. Consequently, repairs can be extremely expensive so it may be best to schedule 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 good 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, as the gas can be toxic in big amounts.

How You Can Solve It

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

  • Switching off your gas supply.
  • Opening windows.
  • Evacuating your home promptly.
  • Getting in touch with your gas company without delay.

3. Air Conditioner Smells Musty

Homeowners who call us regarding this issue usually share 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 frequently caused by a filthy evaporator coil that has mold, mildew and bacteria buildup. Moisture can also make your home air conditioner smell bad. Dirty sock syndrome is most common in areas where you use heating at night and during the morning before switching to cooling later on.

How to Repair It

The best way to prevent dirty sock syndrome is to frequently change your air filter and schedule routine air conditioning maintenance with Van Haaften Plumbing & Heating. We’ll keep the evaporator coil clean and the drainage system flowing, as stagnant water can also create unpleasant odors.

4. Air Conditioner Smells Like Vinegar

If you are experiencing air conditioner mildew smell or a strong, vinegar-like odor, it can be prompted by several issues, such as:

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

How to Solve 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, we recommend replacing it. If that doesn’t fix the issue, reach Van Haaften Plumbing & Heating at 641-628-3621.

5. Air Conditioner Smells Like Burning Plastic

If you’re experiencing an air conditioner burning smell or that your air conditioner smells like fish, there could be a couple of things wrong. These include:

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

Electrical malfunctions should be examined quickly to stop a fire. If you smell burning plastic when your air conditioner is on, turn it off and contact us at 641-628-3621 right away.

6. Air Conditioner Smells Like Cat Pee

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

How to Fix It

Mycotoxins are hazardous to your well-being. That’s why we recommend having a pro like Van Haaften Plumbing & Heating examine your air conditioner and ductwork and clean it when recommended.
