If you’re noticing a smell from your heat pump, it’s attempting to tell you that something is wrong. We’ve created a list of the top six heat pump smells, what causes them and how you can repair them.
- Heat pump smells musty
- Heat pump smells like fish
- Heat pump smells like sulfur
- Heat pump smells like sewer
- Heat pump smells like burning
- Heat pump defrost cycle smells
1. Heat Pump Smells Musty
If your heat pump smells musty, there’s probably mold growing on moist evaporator coils or in the ductwork. This heat pump odor is often referred to as dirty sock syndrome. You can prevent this by scheduling routine heat pump maintenance and air duct cleaning.
2. Heat Pump Smells Like Fish
If your heat pump smells like fish, there could be a couple of things wrong:
- Overheated motor
- Wiring issue
- Plastic components or coating is melting
- Other mechanical problem
Electrical problems are serious, so turn your heat pump system off immediately at the breaker box and contact us at 951-299-9853 for heat pump repair.
3. Heat Pump Smells Like Sulfur
Normally when you smell a rotten egg smell, you have a gas leak. But your heat pump doesn’t use natural gas. If your heat pump smells like sulfur, a small animal may have crawled inside it for warmth and died. One of our Cool Air Solutions [technicians can eliminate the smell by cleaning your heat pump.
4. Heat Pump Smells Like Sewer
As we discussed earlier, your heat pump is electric, so any rotten egg smells are linked to a gas leak somewhere else. If your heat pump smells like sewer, you might have a backed-up or broken sewer line. We suggest getting in touch with a company that does sewer line repair.
5. Heat Pump Smells Like Burning
You might have an electrical problem if your heat pump smells like burning, burning plastic or burning rubber. This burning smell can be caused by melting plastic on electrical wires. Electrical problems in HVAC systems are dangerous and could lead to a fire. If you notice this smell, turn off your heat pump at the breaker and call us at 951-299-9853.
6. Heat Pump Defrost Cycle Smells
Like we talked about earlier, a dirty socks smell can happen when your evaporator coils need to be cleaned. You might notice this smell when your heat pump is in defrost mode.
It’s typical for your heat pump to have to use defrost mode during heating season. When the air is much cooler, frost can form fast on the coils from condensation and impede heating. During defrost mode, your heat pump temporarily switches to air conditioning to remove the frost.
Having a Cool Air Solutions HVAC technician clean the coils will help get rid of the smell.
