When your air conditioner is spotless and running correctly, it’s not normal to be smelling anything odd. Out of the ordinary air conditioner noises and odd smells are a clue that something is up. If your air conditioner is getting older or you haven’t had a tune-up done lately, they can be a clear sign you need pro air conditioning repair in Dresden.
Here are six of the most frequent 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, especially 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 often 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 over time.
Four Signs You Are Dealing with a Refrigerant Leak
Aside from the weird smell, here are four other hints that you are experiencing 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 residence cold or achieving your programmed temperature.
- Increasing energy bills.
How You Can Take Care of It
A refrigerant leak requires professional assistance from a heating and cooling company like McFadden Heating & Cooling. Your cooling professional will pinpoint and fix the leak before recharging your air conditioner with refrigerant.
Fixing a refrigerant leak usually costs between $225 and $1,600, according to nationwide averages put together by HomeAdvisor. Your total cost will depend on the location and severity of the leak, as well as how much time it needs to solve.
If your air conditioner was installed prior to 2010, there’s a high probability it runs on R-22 or Freon refrigerant. This refrigerant is no longer being manufactured because of its harmful effects on the ozone layer. Consequently, repairs can be extremely expensive so it may be smartest to schedule air conditioning installation in this circumstance.
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 good probability you have a natural gas leak in your home. Natural gas has a sulfur-like additive to warn you when there’s a leak, because the gas can be toxic in large amounts.
How You Can Solve It
If you notice a sulfur or rotten egg odor, we suggest:
- Turning off your gas supply.
- Opening windows.
- Going outside as soon as possible.
- Contacting your gas company now.
3. Air Conditioner Smells Musty
Individuals who reach us about this problem often report their air conditioner smells like feet, dirty socks or a locker room when it runs. Also called dirty sock syndrome, this smell is frequently caused by a filthy 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 climates where you turn on heating at night and during the morning before turning on cooling later on.
How to Fix It
The best approach for preventing dirty sock syndrome is to regularly change your air filter and schedule regular air conditioning maintenance with McFadden Heating & Cooling. We’ll keep the evaporator coil clean and the drainage system unblocked, because stagnant water can also create unpleasant odors.
4. Air Conditioner Smells Like Vinegar
If you are living with air conditioner mildew smell or an acidic, vinegar-like odor, it could be prompted by several issues, like:
- A filthy filter
- Excess condensation
- Plugged condensate pan or drain line
- Moldy air conditioner or ductwork
How to Repair 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, we recommend replacing it. If that doesn’t fix the smell, reach McFadden Heating & Cooling at 519-683-2339.
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 involve:
- Broken capacitator that’s overheating the motor.
- Motor that requires lubrication.
- Broken fan belt.
- Electrical malfunctions.
Electrical malfunctions should be examined immediately to avoid a fire. If you smell burning plastic when your air conditioner is on, shut it off and call us at 519-683-2339 immediately.
6. Air Conditioner Smells Like Cat Pee
A strong 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 produces.
How to Solve It
Mycotoxins are hazardous to your well-being. That’s why we recommend having a pro like McFadden Heating & Cooling check your air conditioner and ductwork and clean it when recommended.
