When your air conditioner is spotless and working correctly, it’s not normal to be smelling anything weird. Abnormal air conditioner noises and odd smells are a hint that something is off. 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 skilled air conditioning repair in Cedar Rapids.

Here are six of the most common air conditioner smells and how you can solve 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 might also observe your:

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

These sweet, chemical odors are often a clue that your air conditioner is experiencing a refrigerant leak. Your system uses this gas to shift heat through copper coils, which can break out over time.

Four signs you are dealing with a refrigerant leak.

In addition to the odd smell, here are four other hints that you are experiencing 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 house comfortable or achieving your set temperature.
  4. High electrical bills.

How You Can Repair It

A refrigerant leak needs skilled assistance from a heating and cooling company like Ilten's. Your cooling technician will pinpoint and mend the leak before recharging your AC with refrigerant.

Fixing a refrigerant leak typically costs between $225 and $1,600, based on nationwide averages assembled by HomeAdvisor. Your exact cost will depend on the location and severity of the leak, as well as how much time it takes to repair.

If your air conditioner was installed early than 2010, there’s a high probability it has R-22 or Freon refrigerant. This refrigerant is no longer being manufactured as a result of its harmful effects on the ozone layer. Consequently, repairs can be extremely expensive so it may be best to schedule 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 signal you when there’s a leak, as the gas can be toxic in large amounts.

How You Can Fix It

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

  • Shutting off your gas supply.
  • Opening windows.
  • Going outside promptly.
  • Calling your gas company without delay.

3. Air Conditioner Smells Musty

Individuals who call us regarding this situation usually say their air conditioner smells like feet, dirty socks or a locker room when it runs. Also called 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 often seen in climates where you need heating at night and during the morning before transitioning to cooling later in the day.

How to Repair It

The best approach for preventing dirty sock syndrome is to regularly get a new air filter and schedule regular air conditioning maintenance with Ilten's. We’ll keep the evaporator coil clean and the drainage system unblocked, as standing water can also create unpleasant 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 situations, like:

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

How to Repair 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 resolve the problem, call Ilten's at 319-208-2351.

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 number of things wrong. These entail:

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

Electrical problems should be inspected right away to prevent a fire. If you detect burning plastic when your air conditioner is operating, switch it off and contact us at 319-208-2351 right away.

6. Air Conditioner Smells Like Cat Pee

A powerful ammonia odor means there could be mold growing within 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 health. That’s why it’s important to have a pro like Ilten's look at your air conditioner and ductwork and clean it when recommended.
