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 regular 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:
- Motor is too hot
- Wiring problem
- Plastic components or coating is melting
- Other mechanical problem
Electrical problems are serious, so turn your heat pump system off right away at the breaker box and call us at 402-509-5940 for heat pump repair.
3. Heat Pump Smells Like Sulfur
Normally when you are dealing with a rotten egg smell, you’re dealing with a gas leak. But your heat pump doesn’t use natural gas. If your heat pump smells like sulfur, a little animal may have gotten inside it for warmth and died. One of our Interstate Heating & Air Conditioning [technicians can eliminate the smell by cleaning your heat pump.
4. Heat Pump Smells Like Sewer
As we discussed before, your heat pump is electric, so any rotten egg smells are linked to a gas leak elsewhere. If your heat pump smells like sewer, you might be dealing with a backed-up or broken sewer line. We recommend getting in touch with a company that does sewer line repair.
5. Heat Pump Smells Like Burning
You might have an electrical issue if your heat pump smells like burning, burning plastic or burning rubber. This burning smell can be the result of 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 402-509-5940.
6. Heat Pump Defrost Cycle Smells
Like we talked about earlier, a dirty socks smell can happen when your evaporator coils need cleaning. You might notice this smell when your heat pump is in defrost mode.
It’s common for your heat pump to have to turn on defrost mode during heating season. When the air is much colder, frost can form fast on the coils from condensation and impede heating. During defrost mode, your heat pump briefly switches to cooling to remove the frost.
Having a Interstate Heating & Air Conditioning HVAC technician clean the coils will help eliminate the smell.
