What To Do About a Chemical Smell Coming From Your Air Conditioning

Your home’s central air conditioning system should please several of your senses. First and foremost, the refreshing air should appeal to your sense of touch. You may also see the thermostat set to the right temperature or hear the unit running smoothly. But a sense that is generally not part of the experience is smell. 

What To Do About a Chemical Smell Coming From Your Air Conditioning

If there’s a strange or chemical-like smell coming from your air conditioning, it’s a sign there’s a problem such as a refrigerant leak, mold, or household chemicals getting drawn into the air handler.

Let’s take a deeper look at each of these off-putting scents.

A moldy or musty smell

If you notice a moldy, musty, or ammonia scent coming from the unit or the air vents, it could be a sign that you have mold or mildew growing on your evaporator coil. Mold is especially concerning because the AC could be spreading dangerous spores throughout your home. Call an HVAC professional to inspect and clean the coil and ductwork. 

A sweet, chemical smell

This distinct smell can be described as ether or chloroform – and is a strong signal that you have a refrigerant leak in your air conditioning system. The refrigerant captures and transports heat and is part of a closed system, so it doesn’t run out over time. However, if there is damage or corrosion to the coils, refrigerant can leak out, hurting the AC’s performance and causing a potential health risk. Bring in an HVAC technician ASAP to fix the leak and recharge the refrigerant if needed.

The smell of cleaning chemicals or paint

Does the odd smell remind you of a household chemical or product? You may not be wrong. If products such as cleaners or paints are stored too close to the air handler unit, then fumes could be drawn in and blown throughout the home. To fix this scenario, make sure the containers are completely closed and move the products away from the air handler or into another space.
