When your air conditioner is spotless and running correctly, it’s not normal to be smelling anything weird. Out of the ordinary air conditioner noises and odd smells are a clue that something is wrong. If your air conditioner is aging or you haven’t had service done recently, they can be a sure sign you need pro air conditioning repair in Libertyville.
Here are six of the most frequent air conditioner smells and how you can fix them.
1. Central Air Conditioner Smells Like Chemicals
If your air conditioner smells bad when turned on, especially a chemical odor, it isn’t a positive sign. You might also notice your:
- Air conditioner smells like paint thinner
- Home air conditioner smells sweet
These sweet, chemical odors are typically a sign that your air conditioner has a refrigerant leak. Your system uses this gas to move heat through copper coils, which can crack as time goes on.
Four Clues You Have a Refrigerant Leak
In addition to the odd smell, here are four other signs that you are dealing with a refrigerant leak.
- Bubbling or hissing sounds when your air conditioner is on.
- Ice crystals on refrigerant lines or the evaporator coil.
- It’s hard keeping your home cool or achieving your desired temperature.
- High electrical expenses.
How You Can Take Care of It
A refrigerant leak requires skilled support from a heating and cooling company like TopTec. Your cooling specialist will pinpoint and repair the leak before recharging your AC with refrigerant.
Resolving a refrigerant leak usually 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 long it needs to solve.
If your air conditioner was installed earlier than 2010, there’s a high probability it uses R-22 or Freon refrigerant. This refrigerant is no longer being produced due to its damaging effects on the ozone layer. Because of this, repairs can be very expensive so it may be wisest to do 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 house. Natural gas has a sulfur-like additive to alert you when there’s a leak, as the gas can be toxic in large amounts.
How You Can Repair It
If you notice a sulfur or rotten egg odor, we recommend:
- Shutting off your gas supply.
- Opening windows.
- Evacuating your home promptly.
- Calling your gas company now.
3. Air Conditioner Smells Musty
Individuals who call us regarding this issue often say their air conditioner smells like feet, dirty socks or a locker room when it’s on. Also called dirty sock syndrome, this smell is typically linked to 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 common in areas where you turn on heating at night and during the morning before turning on cooling later on.
How to Repair It
The best way to prevent dirty sock syndrome is to regularly change your air filter and schedule yearly air conditioning maintenance with TopTec. We’ll keep the evaporator coil clean and the drainage system unblocked, because excess water can also create nasty odors.
4. Air Conditioner Smells Like Vinegar
If you are dealing with air conditioner mildew smell or a strong, vinegar-like odor, it might be the result of several issues, including:
- A filthy filter
- Excess condensation
- Blocked 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, it’s time to replace it. If that doesn’t solve the issue, call TopTec at 847-362-0262.
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 several things wrong. These include:
- Broken capacitator that’s overheating the motor.
- Motor that requires lubrication.
- Broken fan belt.
- Electrical problem.
Electrical problems should be examined immediately to avoid a fire. If you smell burning plastic when your air conditioner is on, switch it off and reach us at 847-362-0262 right away.
6. Air Conditioner Smells Like Cat Pee
An overpowering ammonia odor means there might be mold present inside your air conditioner or ductwork. The smell isn’t the mold itself, but the mycotoxins that mold creates.
How to Solve It
Mycotoxins are hazardous to your health. That’s why it’s important to have a specialist like TopTec check your air conditioner and ductwork and clean it when needed.
