If you’re noticing a smell from your heat pump, it’s trying to tell you that something is wrong. We’ve put together a list of the most common 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 likely 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 several things wrong:
- Overheated motor
- Wiring issue
- Plastic components or coating is melting
- Other mechanical issue
Electrical problems are serious, so turn your heat pump system off right away at the breaker box and call us at 562-286-6624 for heat pump repair.
3. Heat Pump Smells Like Sulfur
Usually when you smell a rotten egg smell, you have a gas leak. But your heat pump doesn’t run on natural gas. If your heat pump smells like sulfur, a small animal may have gotten inside it for warmth and died. One of our YES R&M Inc. [techs 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 tied to a gas leak elsewhere. If your heat pump smells like sewer, you might have 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 issues in HVAC systems are serious and could cause a fire. If you notice this smell, shut off your heat pump at the breaker and call us at 562-286-6624.
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 experience 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 cooler, frost can form quickly on the coils from condensation and impede heating. During defrost mode, your heat pump temporarily switches to cooling to remove the frost.
Having a YES R&M Inc. HVAC technician clean the coils will help get rid of the smell.
