When your air conditioner is clean and working correctly, it’s not normal to be smelling anything strange. Out of the ordinary air conditioner noises and strange smells are a sign that something is out of whack. If your air conditioner is old or you haven’t had a tune-up completed lately, 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 resolve 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 positive sign. You may also observe your:
- Air conditioner smells like paint thinner
- Home air conditioner smells sweet
These sweet, chemical scents are often a hint that your air conditioner is suffering from a refrigerant leak. Your system uses this gas to move heat through copper coils, which can break out as time goes on.
Four Hints You Have a Refrigerant Leak
Aside from the strange smell, here are four other signs that you have a refrigerant leak.
- Bubbling or hissing sounds when your air conditioner is cooling.
- Frost on refrigerant lines or the evaporator coil.
- It’s hard keeping your house cool or reaching your programmed temperature.
- Increasing utility bills.
How You Can Take Care of It
A refrigerant leak requires experienced support from a heating and cooling company like B & G HVAC. Your cooling professional will find and fix the leak before recharging your system 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 many hours it needs to fix.
If your air conditioner was installed earlier than 2010, it’s likely it runs on R-22 or Freon refrigerant. This refrigerant is no longer being produced as a result of its adverse effects on the ozone layer. As a consequence, repairs can be very expensive so it may be wisest to schedule air conditioning installation in this instance.
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 high likelihood 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 deadly in heavy concentrations.
How You Can Fix It
If you smell a sulfur or rotten egg odor, we recommend:
- Turning off your gas supply.
- Opening windows.
- Going outside as soon as possible.
- Getting in touch with your gas company immediately.
3. Air Conditioner Smells Musty
Individuals who contact us about this issue frequently mention their air conditioner smells like feet, dirty socks or a locker room when it runs. Also referred to as dirty sock syndrome, this smell is typically linked to a grubby evaporator coil that has mold, mildew and bacteria buildup. Excess water can also make your home air conditioner smell bad. Dirty sock syndrome is most common in locations where you use heating at night and during the morning before switching to cooling during the afternoon.
How to Fix It
The best method for preventing dirty sock syndrome is to frequently get a new air filter and schedule yearly air conditioning maintenance with B & G HVAC. We’ll keep the evaporator coil clean and the drainage system unblocked, because standing water can also lead to noxious odors.
4. Air Conditioner Smells Like Vinegar
If you are dealing with air conditioner mildew smell or a strong, vinegar-like odor, it can be the result of several situations, including:
- A dirty filter
- Excess condensation
- Clogged 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 solve the smell, reach B & G HVAC at 641-316-3360.
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 number of things wrong. These entail:
- Broken capacitator that’s overheating the motor.
- Motor that requires lubrication.
- Broken fan belt.
- Electrical trouble.
Electrical issues should be inspected immediately to avoid a fire. If you detect burning plastic when your air conditioner is on, switch it off and contact us at 641-316-3360 without delay.
6. Air Conditioner Smells Like Cat Pee
An overpowering ammonia odor means there might be mold present 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 wellness. That’s why it’s important to have a pro like B & G HVAC look at your air conditioner and ductwork and clean it when needed.
