Whether you’re trying to deal with a hot Texas summer day or the occasional cold night, you rely on your heat pump. When it isn’t working, you lose your climate-controlled comfort.
Don’t struggle with a faulty system. Discover the top five reasons your heat pump is not working, then call us for expert heat pump repair service in Arlington, TX.
1. Power Issues
Any heat pump troubleshooting should begin with testing the power. If the unit itself or the thermostat is not receiving power, your heat pump won’t work.
The main heat pump unit has multiple areas with power switches. If someone inadvertently turns off one of these switches, the heat pump stops working. Switches can be located:
- Near the indoor air handler
- On the outdoor unit
- On the exterior wall where the lines enter the building
2. Malfunctioning Thermostat
If your heat pump is not working, one of the first signs is its inability to maintain a consistent temperature. On a hot summer day in Arlington, TX, you’ll notice the issue quickly when the temperature in your home or business soars beyond the thermostat’s setting.
Sometimes, a problem that seems related to the heat pump actually originates with the thermostat. Make sure someone did not change the thermostat’s settings, making it appear that your heat pump is malfunctioning:
- The thermostat’s fan should be set to auto.
- Make sure the fan is not turned off.
- See if the thermostat’s temperature set point is correct.
Additionally, your thermostat needs electricity. If you don’t see any thermostat settings on the display screen, the unit isn’t receiving power.
Fixing an electrical issue with the thermostat could involve changing the unit’s batteries. If the thermostat is hard-wired into your electrical system, a tripped circuit breaker could be the problem.
If the thermostat doesn’t respond to changes you make to the settings or if the display screen is blank, call for service.
3. Dirty Air Filter
Because of how a heat pump works, a dirty or clogged air filter can cause the unit to shut down. The air filter catches dust and other airborne particles before they can build up on the unit’s components.
When a heat pump is not working, check the filter. If you see an excessive accumulation of dust, change it or clean it. Air filters need regular maintenance like this to allow normal airflow for the heat pump. Without steady airflow, the unit may shut down to avoid damaging itself.
Some heat pumps do not shut themselves down in time. If the interior components overheat from a dirty air filter, it could cause parts to break down, necessitating repair.
4. Blockages
Blockages inside and outside your home or business could explain why the heat pump isn’t working.
Inspect the vents and registers inside the building. Remove any items blocking them, ensuring they can draw and expel air as intended.
You can inspect the outdoor unit for blockages, too. In Arlington, TX, cottonwood seeds, leaves, and other debris can accumulate on the outdoor unit. Such items can cause the unit to stop working because it can’t dissipate heat properly.
When the temperature falls below freezing during Arlington winters, the outdoor unit may need to run a defrost cycle. This melts frost that could be blocking the outdoor coils. The unit may temporarily stop generating heat indoors during this cycle.
5. Broken Parts
Your heat pump could have broken parts that need repair. You could experience:
- Compressor failure
- Broken starter capacitor
- Malfunctioning reversing valve
- Low refrigerant level
- Broken compressor contactor
Only certified technicians should try to change parts or work with the wiring inside the heat pump. These professionals can carefully examine your system to locate the origin of the problem. From there, they can provide you with safe and effective repairs to get your system working again.
