If you’re discovering a odor from your heat pump, it’s trying to tell you that something is up. We’ve put together a list of the most popular six heat pump smells, what causes them and how you can fix 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 most likely mold growing on damp evaporator coils or in the ductwork. This heat pump odor is often known as dirty sock syndrome. You can deter 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:
- Motor is too hot
- Wiring problems
- Plastic components or coating is melting
- Other mechanical issue
Electrical problems are serious, so shut your heat pump system off as soon as possible at the breaker box and get a hold of us at for heat pump repair.
3. Heat Pump Smells Like Sulfur
Normally when you are dealing with a rotten egg smell, you’ve got a gas leak. But your heat pump doesn’t utilize natural gas. If your heat pump smells like sulfur, a little animal may have gotten inside it for warmth and died. One of our Childress Heating & AC experts can remove 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 elsewhere. If your heat pump smells like sewer, you might currently have a backed-up or broken sewer line. We advise calling 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 unsafe and could cause a fire. If you notice this smell, turn off your heat pump at the breaker and call us at .
6. Heat Pump Defrost Cycle Smells
Like we talked about above, a dirty socks smell can happen when your evaporator coils need to be cleaned. You might notice this smell when your heat pump goes into defrost mode.
It’s typical for your heat pump to have to turn on defrost mode during heating season. When the air is much colder, frost can form quickly on the coils from condensation and interfere with heating. During defrost mode, your heat pump shortly switches to ac to remove the frost.
Having a Childress Heating & AC HVAC technician clean the coils will help eliminate the odor.
