When your air conditioner is clean and working correctly, it’s not normal to be smelling anything odd. Out of the ordinary air conditioner noises and weird smells are a hint that something is wrong. If your air conditioner is getting older or you haven’t had service completed lately, they can be a clear sign you need skilled air conditioning repair in Lancaster.
Here are six of the top 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, particularly a chemical scent, it isn’t a great sign. You may also observe your:
- Air conditioner smells like paint thinner
- Home air conditioner smells sweet
These sweet, chemical smells 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 wear out over time.
Four Clues You Are Dealing with a Refrigerant Leak
Besides the strange smell, here are four other clues that you have a refrigerant leak.
- Bubbling or hissing sounds when your air conditioner is on.
- Ice on refrigerant lines or the evaporator coil.
- Difficulty keeping your residence cold or achieving your set temperature.
- High energy expenses.
How You Can Take Care of It
A refrigerant leak calls for skilled assistance from a heating and cooling company like Fairfield Heating & Cooling. Your cooling specialist will pinpoint and fix the leak before recharging your air conditioner with refrigerant.
Repairing a refrigerant leak often costs between $225 and $1,600, per nationwide averages put together by HomeAdvisor. Your exact cost will depend on the location and severity of the leak, as well as how many hours it needs to solve.
If your air conditioner was installed before 2010, it’s likely it runs on R-22 or Freon refrigerant. This refrigerant is no longer being produced because of its harmful effects on the ozone layer. Because of this, repairs can be significantly expensive so it may be best to do air conditioning installation in this situation.
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 high chance you have a natural gas leak in your house. Natural gas has a sulfur-like additive to signal you when there’s a leak, since the gas can be toxic in heavy concentrations.
How You Can Solve It
If you notice a sulfur or rotten egg odor, we recommend:
- Turning off your gas supply.
- Opening windows.
- Going outside as soon as possible.
- Calling your gas company without delay.
3. Air Conditioner Smells Musty
People who contact us to report this issue frequently say 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 frequently created by a filthy 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 climates where you turn on heating at night and during the morning before switching to cooling later in the day.
How to Solve It
The best approach for preventing dirty sock syndrome is to routinely change your air filter and schedule yearly air conditioning maintenance with Fairfield Heating & Cooling. 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 dealing with air conditioner mildew smell or an acidic, vinegar-like odor, it can be the result of several situations, such as:
- A dirty filter
- Excess condensation
- Plugged condensate pan or drain line
- Moldy air conditioner or ductwork
How to Repair 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, we recommend replacing it. If that doesn’t solve the smell, contact Fairfield Heating & Cooling at 740-331-4331.
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 include:
- Broken capacitator that’s overheating the motor.
- Motor that requires lubrication.
- Broken fan belt.
- Electrical issue.
Electrical malfunctions should be inspected right away to prevent a fire. If you smell burning plastic when your air conditioner is on, shut it off and call us at 740-331-4331 without delay.
6. Air Conditioner Smells Like Cat Pee
A powerful ammonia odor means there might be mold present 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 you should have a professional like Fairfield Heating & Cooling examine your air conditioner and ductwork and clean it when necessary.
