When your air conditioner is spotless and operating right, it’s not normal to be smelling anything weird. Unexpected air conditioner noises and strange smells are a sign that something is off. If your air conditioner is getting older or you haven’t had maintenance scheduled lately, they can be an obvious sign you need skilled air conditioning repair in Heflin.
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 positive sign. You may also observe your:
- Air conditioner smells like paint thinner
- Home air conditioner smells sweet
These sweet, chemical scents are typically a sign that your air conditioner is experiencing a refrigerant leak. Your system needs this gas to transfer heat through copper coils, which can crack as time passes.
Four Clues You Are Experiencing a Refrigerant Leak
Besides the strange smell, here are four other hints that you have a refrigerant leak.
- Bubbling or hissing sounds when your air conditioner is on.
- Frost on refrigerant lines or the evaporator coil.
- Difficulty keeping your home cool or having your desired temperature.
- Higher electrical costs.
How You Can Repair It
A refrigerant leak calls for professional repairs from a heating and cooling company like Bain Heating & Air Conditioning. Your cooling technician will pinpoint and mend the leak before recharging your AC with refrigerant.
Repairing a refrigerant leak typically costs between $225 and $1,600, according to nationwide averages compiled by HomeAdvisor. Your precise cost will depend on the location and severity of the leak, as well as how much time it needs to solve.
If your air conditioner was installed prior to 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. Due to this, repairs can be very expensive so it may be best to do 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 significant chance you have a natural gas leak in your home. Natural gas has a sulfur-like additive to signal you when there’s a leak, because the gas can be fatal in large amounts.
How You Can Fix It
If you notice a sulfur or rotten egg odor, we suggest:
- Turning off your gas supply.
- Opening windows.
- Evacuating your home promptly.
- Contacting your gas company immediately.
3. Air Conditioner Smells Musty
People who reach us about this issue often share their air conditioner smells like feet, dirty socks or a locker room when it’s on. Also referred to as dirty sock syndrome, this smell is often caused by a grubby evaporator coil that has mold, mildew and bacteria buildup. Condensation can also make your home air conditioner smell bad. Dirty sock syndrome is most common in climates where you need heating at night and during the morning before switching to cooling during the afternoon.
How to Fix It
The best approach for preventing dirty sock syndrome is to regularly change your air filter and schedule yearly air conditioning maintenance with Bain Heating & Air Conditioning. We’ll keep the evaporator coil clean and the drainage system flowing, since standing water can also produce unpleasant odors.
4. Air Conditioner Smells Like Vinegar
If you are living with air conditioner mildew smell or an acidic, vinegar-like odor, it can be the result of several problems, including:
- A filthy filter
- Excess condensation
- Blocked condensate pan or drain line
- Moldy air conditioner or ductwork
How to Resolve It
Examine your filter first. If you haven’t changed it within the last three months and can’t see light through it, it’s time to replace it. If that doesn’t fix the smell, call Bain Heating & Air Conditioning at 256-270-1196.
5. Air Conditioner Smells Like Burning Plastic
If you’re dealing with 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 malfunctions.
Electrical issues should be examined immediately to avoid a fire. If you notice burning plastic when your air conditioner is on, turn it off and reach us at 256-270-1196 without delay.
6. Air Conditioner Smells Like Cat Pee
A powerful ammonia odor means there could be mold spreading in your air conditioner or ductwork. The smell isn’t the mold itself, but the mycotoxins that mold produces.
How to Repair It
Mycotoxins are hazardous to your well-being. That’s why it’s important to have a specialist like Bain Heating & Air Conditioning check your air conditioner and ductwork and clean it when recommended.
