Your heat pump is an important part of your home because it produces year-round comfort. But, like any home comfort system, it’s likely to experience some problems every now and then.
Let’s go over these troubles and how much they might cost to fix, so you’ll have some idea before you contact an HVAC technician. Some of the most typical heat pump repair problems include:
- Heat pump won’t turn on
- Heat pump won’t turn off
- Heat pump won’t defrost
- Heat pump won’t cool
- Heat pump won’t turn on after changing thermostat
- Heat pump won’t heat
1. Heat Pump Isn’t Turning On
There are plenty of reasons why your heat pump won’t turn on, so we recommend checking all of them. Sometimes they are as simple as correcting a thermostat setting or changing your air filter.
Here’s what to check:
- Is your thermostat on the proper setting? If you want cooling, make sure it’s set to “cool,” “auto” and that your setting is lower than the room temperature. If you want heat, it should be set to “heat,” “auto” and your setting should be higher than the current temperature. If you have a programmable thermostat, replace the batteries if the screen looks jumbled or blank.
- Has the circuit breaker been tripped? Your heat pump won’t be able to turn on if it lacks power. Reset the corresponding breaker if it’s facing the outside of the electrical panel.
- Is the air filter clogged? A dirty air filter is problematic for your heat pump. If you can’t see light through it, it’s time to replace it.
If these steps don’t correct the problem, you’ll need to contact a heating and cooling company like Done Right Air.
Estimated Repair Cost
This issue can be complex, so how much it costs to fix it will depend on what’s wrong.
2. Heat Pump Stays On Constantly
If it’s very hot or cold outside, your heat pump may need to run longer than normal to achieve your desired temperature.
If the weather is typical, check that your thermostat is set properly and running normally. If the fan setting is at “on,” the blower motor on your air handler will run 24/7. So, it’ll sound like your heat pump is working all the time. Constantly using the blower can keep humidity levels under control, but it’ll also increase your electrical bills.
If your thermostat is set properly, there are several other issues that could be causing your heat pump to run all the time. They include:
- A new thermostat that isn’t compatible with your heat pump.
- A malfunctioning compressor contactor, which controls the flow of electricity.
- Leaky ductwork.
Estimated Repair Cost
This can be linked to a few issues, so your heat pump repair cost will depend on the problem and how difficult it is.
3. Heat Pump Won’t Defrost
Every now and then during cold weather, your heat pump will temporarily go into cooling mode. This will melt light frost and ice that naturally builds up on the coils. A heat pump that becomes totally frozen may have difficulty heating your home or shut down completely.
Here are a few reasons why this might be taking place:
- Your heat pump doesn’t have sufficient airflow because it’s blocked by snow, bushes or yard waste.
- Your gutters are dripping water on top of your heat pump, causing an icy buildup.
- A part is not working, which may consist of the reversing valve, relays, controls or sensors.
- The outdoor fan motor is damaged, dying or dead.
- Your heat pump has a refrigerant leak. This is possible if you’re hearing bubbling or hissing sounds. Or if you discover a sweet, formaldehyde-like odor near the outdoor unit.
Estimated Repair Cost
Like we talked about before, there are a few reasons why your heat pump won’t defrost. But here are several estimated costs for some of these issues. Keep in mind your cost may vary based on your heat pump brand, model and the degree of the issue.
- Replace reversing valve: $200–$600
- Replace outdoor fan motor: $250–$650
- Repair refrigerant leak: Depends on the type of refrigerant your heat pump uses. R-22 Freon is pricier since it’s no longer being made.
4. Heat Pump Isn’t Cooling
Just like a heat pump that won’t turn on, a heat pump that won’t cool can be linked to many problems. We suggest checking for:
- Correct thermostat settings
- Tripped circuit breakers
- A clogged air filter
- Ice on your heat pump
If there’s nothing wrong with your thermostat, circuit breakers or air filter, you’ll need assistance from an HVAC technician to diagnose a problem with your ductwork or an iced-over heat pump. Like we discussed earlier, a heat pump that won’t defrost might have a problem with its reversing valve, outdoor fan motor or a refrigerant leak.
Estimated Repair Costs
These repair costs are estimates. Your total charge may vary based on your heat pump brand, model and the severity of the concern.
- Replace reversing valve: $200–$600
- Replace outdoor fan motor: $250–$650
- Repair refrigerant leak: Depends on the kind of refrigerant your heat pump uses. R-22 Freon is pricier since it’s no longer being manufactured.
- Seal leaky ductwork: Depends on house size.
5. Heat Pump Malfunctions After Changing Thermostat
If your heat pump won’t turn on after changing the thermostat, the problem is probably connected to your new thermostat. While you can use just about any thermostat with a furnace, the same isn’t true for heat pumps, especially if you have backup or emergency heating.
You can check your new thermostat by changing the fan mode to “on.” If you don’t hear the blower motor running in your air handler, there’s probably an issue with the thermostat.
A couple other typical thermostat problems include:
- Wiring was done wrong.
- Thermostat isn’t interacting with heat pump.
- Thermostat is in emergency heat mode, which involves a reset.
It’s recommended to have a heating and cooling professional recommend a thermostat and expertly install it. That way, you’ll stay away from any compatibility or wiring problems.
Estimated Repair Costs
The cost of professional thermostat installation depends greatly on what kind of thermostat you want. While programmable thermostats are cheaper, they are missing the sophisticated features and convenience of a smart thermostat.
6. Heat Pump Won’t Heat
A heat pump that won’t heat is connected to similar problems with a heat pump that won’t cool. We suggest checking for:
- Correct thermostat settings
- Tripped circuit breakers
- A clogged air filter
- Ice on your heat pump
An icy heat pump or leaky ductwork will require the assistance of an HVAC technician. Ductwork is tricky to reach since it’s located behind walls and several issues can cause your heat pump to ice over.
Estimated Repair Costs
These repair costs are estimates. Your total cost may vary based on your heat pump brand, model and the level of the concern.
- Replace reversing valve: $200–$600
- Replace outdoor fan motor: $250–$650
- Repair refrigerant leak: Depends on the kind of refrigerant your heat pump runs on. R-22 Freon is higher priced since it’s no longer being manufactured.
- Seal leaky ductwork: Depends on house size.
