When your air conditioner is spotless and running right, it’s expected you won’t be smelling anything strange. Unusual air conditioner noises and strange smells are a hint that something is out of whack. If your air conditioner is aging or you haven’t had a tune-up completed within the last year, they can be an obvious sign you need pro air conditioning repair in Ballwin and St. Charles.
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, specifically a chemical scent, it isn’t a positive sign. You might also notice your:
- Air conditioner smells like paint thinner
- Home air conditioner smells sweet
These sweet, chemical odors are frequently a clue that your air conditioner has a refrigerant leak. Your system relies on this gas to transfer heat through copper coils, which can wear out as time passes.
Four Signs You Are Experiencing a Refrigerant Leak
Aside from the odd smell, here are four other signs that you are dealing with a refrigerant leak.
- Bubbling or hissing sounds when your air conditioner is operating.
- Ice on refrigerant lines or the evaporator coil.
- It’s hard keeping your house comfortable or achieving your desired temperature.
- High energy expenses.
How You Can Repair It
A refrigerant leak needs professional support from a heating and cooling company like Air Alliance Team. Your cooling specialist will pinpoint and fix the leak before recharging your system with refrigerant.
Fixing a refrigerant leak usually costs between $225 and $1,600, according to nationwide averages assembled by HomeAdvisor. Your precise cost will depend on the location and severity of the leak, as well as how long it needs to repair.
If your air conditioner was installed before 2010, there’s a high probability it has R-22 or Freon refrigerant. This refrigerant is no longer being manufactured due to its negative effects on the ozone layer. As a consequence, repairs can be significantly expensive so it may be wisest to consider air conditioning installation in this circumstance.
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 good probability you have a natural gas leak in your house. Natural gas has a sulfur-like additive to signal you when there’s a leak, because the gas can be deadly in heavy concentrations.
How You Can Repair It
If you notice a sulfur or rotten egg odor, we advise:
- Shutting off your gas supply.
- Opening windows.
- Going outside right away.
- Contacting your gas company immediately.
3. Air Conditioner Smells Musty
Individuals who call us to report this situation 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 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 areas where you need heating at night and during the morning before turning on cooling during the afternoon.
How to Fix It
The best method for preventing dirty sock syndrome is to regularly get a new air filter and schedule yearly air conditioning maintenance with Air Alliance Team. We’ll keep the evaporator coil clean and the drainage system unclogged, because standing water can also produce noxious odors.
4. Air Conditioner Smells Like Vinegar
If you are experiencing air conditioner mildew smell or a pungent, vinegar-like odor, it can be caused by several situations, such as:
- A filthy filter
- Too much condensation
- Clogged condensate pan or drain line
- Moldy air conditioner or ductwork
How to Resolve It
Inspect 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 fix the issue, call Air Alliance Team at 636-206-4250.
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 include:
- Broken capacitator that’s overheating the motor.
- Motor that needs lubrication.
- Broken fan belt.
- Electrical problem.
Electrical problems should be checked right away to avoid a fire. If you smell burning plastic when your air conditioner is running, switch it off and reach us at 636-206-4250 immediately.
6. Air Conditioner Smells Like Cat Pee
A strong ammonia odor means there may be mold growing within your air conditioner or ductwork. The smell isn’t the mold itself, but the mycotoxins that mold creates.
How to Repair It
Mycotoxins are hazardous to your health. That’s why it’s important to have a pro like Air Alliance Team look at your air conditioner and ductwork and clean it when recommended.
