If you’re noticing a smell from your heat pump, it’s trying to tell you that something is up. We’ve created 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 probably mold growing on wet evaporator coils or in the ductwork. This heat pump odor is often referred to as dirty sock syndrome. You can avoid 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:
- Overheated motor
- Wiring problem
- Plastic components or coating is melting
- Other mechanical issue
Electrical problems are dangerous, so turn your heat pump system off immediately at the breaker box and contact us at 863-216-2923 for heat pump repair.
3. Heat Pump Smells Like Sulfur
Normally when you are dealing with 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 crawled inside it for warmth and died. One of our Air Commander's Heating & Air Conditioning Co. [technicians can eliminate the smell by cleaning your heat pump.
4. Heat Pump Smells Like Sewer
As we mentioned earlier, your heat pump is electric, so any rotten egg smells are tied to a gas leak somewhere else. If your heat pump smells like sewer, you might be dealing with a backed-up or broken sewer line. We suggest contacting a company that does sewer line repair.
5. Heat Pump Smells Like Burning
You might be dealing with an electrical issue 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 issues 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 863-216-2923.
6. Heat Pump Defrost Cycle Smells
Like we talked about previously, a dirty socks smell can happen when your evaporator coils need cleaning. You might experience this smell when your heat pump goes into defrost mode.
It’s common 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 briefly switches to cooling to get rid of the frost.
Having a Air Commander's Heating & Air Conditioning Co. HVAC technician clean the coils will help eliminate the odor.
