When your air conditioner is spotless and operating properly, it’s not normal to be smelling anything odd. Unusual air conditioner noises and weird smells are a hint that something is wrong. If your air conditioner is old or you haven’t had a tune-up done within the last year, they can be a clear sign you need pro air conditioning repair in Athol.
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 smell, it isn’t a great sign. You may also report your:
- Air conditioner smells like paint thinner
- Home air conditioner smells sweet
These sweet, chemical odors are frequently a sign that your air conditioner has a refrigerant leak. Your system needs this gas to move heat through copper coils, which can break out over time.
Four Clues You Are Dealing with a Refrigerant Leak
In addition to the odd smell, here are four other hints that you have a refrigerant leak.
- Bubbling or hissing sounds when your air conditioner is cooling.
- Frost on refrigerant lines or the evaporator coil.
- Trouble keeping your home cool or achieving your programmed temperature.
- High energy expenses.
How You Can Take Care of It
A refrigerant leak calls for experienced assistance from a heating and cooling company like Alpine Summit Heating & Cooling. Your cooling pro will locate and mend the leak before recharging your air conditioner with refrigerant.
Resolving a refrigerant leak typically costs between $225 and $1,600, per nationwide averages compiled by HomeAdvisor. Your precise cost will depend on the location and severity of the leak, as well as how many hours it requires to fix.
If your air conditioner was installed earlier than 2010, it’s likely it uses R-22 or Freon refrigerant. This refrigerant is no longer being made due to its negative effects on the ozone layer. Because of this, repairs can be extremely expensive so it may be smartest to schedule air conditioning installation in this situation.
2. Air Conditioner Smells Like Gas
If your air conditioner smells like rotten eggs, there’s possibly nothing wrong with it. But there’s a high 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, because the gas can be toxic in large amounts.
How You Can Repair It
If you smell a sulfur or rotten egg odor, we suggest:
- Shutting off your gas supply.
- Opening windows.
- Evacuating your home promptly.
- Contacting your gas company without delay.
3. Air Conditioner Smells Musty
People who call us regarding this problem often mention their air conditioner smells like feet, dirty socks or a locker room when it’s running. 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 often seen in areas where you need heating at night and during the morning before turning on cooling later in the day.
How to Repair It
The best method for preventing dirty sock syndrome is to regularly change your air filter and schedule regular air conditioning maintenance with Alpine Summit Heating & Cooling. We’ll keep the evaporator coil clean and the drainage system unblocked, since stagnant water can also result in nasty 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 the result of several problems, such as:
- A dirty filter
- Too much condensation
- Blocked condensate pan or drain line
- Moldy air conditioner or ductwork
How to Resolve It
Examine 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 fix the issue, call Alpine Summit Heating & Cooling at 208-561-1226.
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 needs lubrication.
- Broken fan belt.
- Electrical problem.
Electrical problems should be checked immediately to avoid a fire. If you smell burning plastic when your air conditioner is on, turn it off and reach us at 208-561-1226 without delay.
6. Air Conditioner Smells Like Cat Pee
An overpowering ammonia odor means there could be mold flourishing in your air conditioner or ductwork. The smell isn’t the mold itself, but the mycotoxins that mold makes.
How to Repair It
Mycotoxins are hazardous to your well-being. That’s why it’s important to have a pro like Alpine Summit Heating & Cooling check your air conditioner and ductwork and clean it when recommended.
