When your air conditioner is fresh and running correctly, it’s not normal to be smelling anything strange. Unusual air conditioner noises and weird smells are a hint that something is up. If your air conditioner is aging or you haven’t had a tune-up scheduled within the last year, they can be a sure sign you need professional air conditioning repair in Cache Valley.
Here are six of the top 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, particularly a chemical scent, it isn’t a good sign. You might also notice your:
- Air conditioner smells like paint thinner
- Home air conditioner smells sweet
These sweet, chemical smells are often a sign that your air conditioner is suffering from a refrigerant leak. Your system uses this gas to shift heat through copper coils, which can break out as time goes on.
Four Hints You Have a Refrigerant Leak
Besides the weird smell, here are four other hints 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.
- It’s hard keeping your residence cool or achieving your desired temperature.
- Higher utility expenses.
How You Can Fix It
A refrigerant leak calls for professional repairs from a heating and cooling company like Western Mechanical, Inc.. Your cooling technician will pinpoint and repair the leak before recharging your system with refrigerant.
Resolving a refrigerant leak typically costs between $225 and $1,600, based on nationwide averages put together by HomeAdvisor. Your precise cost will depend on the location and severity of the leak, as well as how much time it takes to solve.
If your air conditioner was installed earlier than 2010, there’s a good chance it runs on R-22 or Freon refrigerant. This refrigerant is no longer being made as a result of its damaging effects on the ozone layer. As a result, repairs can be extremely expensive so it may be best to consider 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 significant probability 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 fatal in big amounts.
How You Can Solve It
If you detect a sulfur or rotten egg odor, we advise:
- Switching off your gas supply.
- Opening windows.
- Evacuating your home promptly.
- Calling your gas company immediately.
3. Air Conditioner Smells Musty
People who call us about this issue often mention their air conditioner smells like feet, dirty socks or a locker room when it’s on. Also called dirty sock syndrome, this smell is frequently caused by 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 typical in locations where you turn on heating at night and during the morning before switching to cooling later in the day.
How to Repair It
The best approach for preventing dirty sock syndrome is to frequently change your air filter and schedule yearly air conditioning maintenance with Western Mechanical, Inc.. We’ll keep the evaporator coil clean and the drainage system flowing, 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 an acidic, vinegar-like odor, it might be the result of several problems, like:
- A clogged filter
- Extra condensation
- Plugged condensate pan or drain line
- Moldy air conditioner or ductwork
How to Resolve It
Check your filter first. If you haven’t put in a new one within the last three months and can’t see light through it, it’s time to replace it. If that doesn’t fix the problem, reach Western Mechanical, Inc. at 435-753-5515.
5. Air Conditioner Smells Like Burning Plastic
If you’re noticing an air conditioner burning smell or that your air conditioner smells like fish, there could be a couple of things wrong. These include:
- Broken capacitator that’s overheating the motor.
- Motor that should have lubrication.
- Broken fan belt.
- Electrical issue.
Electrical problems should be checked quickly to stop a fire. If you detect burning plastic when your air conditioner is operating, turn it off and reach us at 435-753-5515 immediately.
6. Air Conditioner Smells Like Cat Pee
An overpowering ammonia odor means there could be mold growing inside your air conditioner or ductwork. The smell isn’t the mold itself, but the mycotoxins that mold makes.
How to Fix It
Mycotoxins are hazardous to your health. That’s why we recommend having a specialist like Western Mechanical, Inc. check your air conditioner and ductwork and clean it when necessary.
