While heat pumps are designed to last up to 15 years, you can sometimes experience issues with their operation. The following are some warning signs that your heat pump has a serious problem.
Your Heat Pump Is Not Turning On
If you try to start up your heat pump and nothing happens, check your breaker to make sure it has not tripped. If your breaker is still in the “On” position, check your thermostat settings. If your thermostat is set correctly, you need to call a professional for help.
The following problems can cause your heat pump not to run:
- The reversing valve is malfunctioning.
- The starter capacitor has failed.
- The heat pump is no longer connected to the thermostat.
- The connections inside the heat pump have broken down.
- The wires are frayed.
The Heat Pump Blows Cold Air on the Heat Setting
When your heat pump is not heating your home, chances are that your reversing valve is faulty. Your heat pump may also be clogged and in need of a thorough cleaning by a professional. A low refrigerant level could also be the culprit. Low refrigerant levels can also cause your heat pump not to cool your home. In addition, there is the possibility that a compressor failure might be to blame.
You Notice Strange Smells While the Heat Pump Is Running
If you smell a rotting smell while your heat pump is running, this can mean that an animal has crawled inside your heat pump and died. If you notice a burning smell, you have an electrical problem. In this scenario, you need to shut off your heat pump and call for help immediately. If the air blowing from your system smells musty, you likely have biological growth in your unit and need professional cleaning.
You Hear Odd Sounds
You will hear some noise when your heat pump is running; however, if you hear rattling or screeching sounds, you are in trouble. These noises are indications that a part has come loose or there is a problem with your fan belt. A failing motor can also cause this issue.
The System Keeps Running
While a thermostat that is not calibrated properly can cause your heat pump to run incessantly, this problem can also be the result of a broken compressor contactor. The compressor contactor is designed to control the flow of power that is coming into your system. When this part is broken, nothing controls power levels.
These signs suggest a serious problem, so it is important to act quickly. If you notice any of these signs and live in College Station, TX, hurry and call us at Cover HVAC for heat pump services.
