When your air conditioner is clean and operating right, it’s not normal to be smelling anything strange. Unusual air conditioner noises and weird smells are a clue that something is wrong. If your air conditioner is getting older or you haven’t had a tune-up done lately, they can be an obvious sign you need professional air conditioning repair in Mankato area.
Here are six of the most frequent 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, particularly a chemical odor, it isn’t a positive sign. You could also observe your:
- Air conditioner smells like paint thinner
- Home air conditioner smells sweet
These sweet, chemical smells are frequently a sign that your air conditioner has a refrigerant leak. Your system needs this gas to transfer heat through copper coils, which can break out as time goes on.
Four Clues You Are Dealing with a Refrigerant Leak
In addition to the weird smell, here are four other signs that you have a refrigerant leak.
- Bubbling or hissing sounds when your air conditioner is operating.
- Ice crystals on refrigerant lines or the evaporator coil.
- Difficulty keeping your house cold or achieving your set temperature.
- Higher electrical expenses.
How You Can Take Care of It
A refrigerant leak needs experienced repairs from a heating and cooling company like Northern Comfort Inc. Your cooling pro will locate and mend the leak before recharging your air conditioner with refrigerant.
Repairing a refrigerant leak usually costs between $225 and $1,600, per nationwide averages assembled by HomeAdvisor. Your total cost will depend on the location and severity of the leak, as well as how much time it requires to repair.
If your air conditioner was installed before 2010, there’s a high probability it runs on R-22 or Freon refrigerant. This refrigerant is no longer being manufactured as a result of its harmful effects on the ozone layer. As a consequence, repairs can be very expensive so it may be smartest to do air conditioning installation in this instance.
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 significant likelihood you have a natural gas leak in your residence. Natural gas has a sulfur-like additive to signal you when there’s a leak, because the gas can be toxic in big amounts.
How You Can Repair It
If you detect a sulfur or rotten egg odor, we recommend:
- Switching off your gas supply.
- Opening windows.
- Leaving your home right away.
- Contacting your gas company without delay.
3. Air Conditioner Smells Musty
Individuals who contact us to report this problem usually report their air conditioner smells like feet, dirty socks or a locker room when it’s running. Also referred to as dirty sock syndrome, this smell is usually caused by a dirty 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 areas where you turn on heating at night and during the morning before turning on cooling during the afternoon.
How to Repair It
The best approach for preventing dirty sock syndrome is to frequently change your air filter and schedule annual air conditioning maintenance with Northern Comfort Inc. We’ll keep the evaporator coil clean and the drainage system unblocked, since standing water can also lead to unpleasant odors.
4. Air Conditioner Smells Like Vinegar
If you are living with air conditioner mildew smell or a pungent, vinegar-like odor, it could be prompted by several problems, like:
- A clogged filter
- Too much condensation
- Clogged condensate pan or drain line
- Moldy air conditioner or ductwork
How to Solve It
Examine your filter first. If you haven’t put in a new one within the last three months and can’t see light through it, you should replace it. If that doesn’t solve the smell, call Northern Comfort Inc at 507-387-6596.
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 several things wrong. These involve:
- Broken capacitator that’s overheating the motor.
- Motor that should have lubrication.
- Broken fan belt.
- Electrical problem.
Electrical problems should be inspected immediately to avoid a fire. If you smell burning plastic when your air conditioner is operating, shut it off and call us at 507-387-6596 without delay.
6. Air Conditioner Smells Like Cat Pee
A powerful ammonia odor means there might be mold spreading 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 wellness. That’s why we recommend having a professional like Northern Comfort Inc check your air conditioner and ductwork and clean it when recommended.
