Working of heat pumps
Before knowing about heat pump troubleshooting it is important to learn about how heat pumps actually operate. Heat pumps dont operate like traditional systems, they dont generate heat like them, instead they move heat from one place to another. Like In winter they extract heat from outside and maintain the indoor temperature. In summer heat pumps extract heat from inside and maintain the temperature. Heat pumps operate all year round so they also face some issues as compared to systems that operate once a year. So their maintenance and troubleshooting is especially important.
Common Heat Pump Problems and Troubleshooting Solutions
Following are some heat pump problems that many homeowners face and steps that you can take to resolve them and maintain their efficiency, performance.
Blowing Cold Air in Heat Mode
One of the most frequent issues that homeowners complain about is that in winters heat pumps blow cold air instead of warm air. So this situation means the heat pump is not heating troubleshooting as the system is running but it is unable to deliver warm air as required.
Possible causes behind this issue can be:
- You set the thermostat incorrectly
- Dirty air filters which restricts the airflow
- Malfunctioning reversing valve
- Low level of refrigerants
- Heat pump is in defrost cycle
Defrost cycle means that the system operates in such a way for melting ice from outdoor units. During this operation heat pumps often blow cool air.
Troubleshooting tips
- Make sure that the thermostat is set to Heat mode.
- Regularly check vents so that air cannot be blocked
- Replace dirty or clogged filters
- Inspect the outdoor unit for ice buildup
Even after these steps your issue still persists and it is becoming more worse with time then professional help becomes necessary. That’s why our technicians at Milehi HVAC inspect refrigerator levels and other components to stabilize the heating performance.
Heat Pump Running Constantly in Moderate Weather
As heat pumps run in more cycles as compared to furnaces but if they operate in longer cycles even in mild weather it means that there is some issue.
In this case many homeowners assume that the heat pump quit working as it never seems to shut off.
Possible causes behind this can be:
- Poor insulation
- Dirty air filters
- Issues of refrigerator
- Incorrect size of HVAC system
Troubleshooting tips
- Check doors and windows for any air leak
- Clean or replace the filters regularly
- Make sure that vents are open
This issue is commonly due to the size of the system and issue of the refrigerator which reduces the efficiency of heat pumps working.
Outdoor Unit Is Blocked
The outdoor units of your homes play a significant role in the transferring heat. If there is some blockage in flow of air then the heat pump will not perform effectively.
This leads to heat pump not heating troubleshooting because the components work hard to extract the heat from outside.
Common causes:
- Buildup of leaves and debris
- Snow accumulation
- There is growth of plants and shrubs very close to unit
- Grass clippings
Troubleshooting tips
- Keep your outdoor unit clean at least around 2 feets
- Clean the dirt and debris regularly
- If there is heavy snowfall clean the areas as early as possible
- Trim any vegetation nearby the unit
Proper airflow and maintenance prevents any performance issues and reduces any strains on your heat pump.
Outdoor Unit Is Frozen
In winter seasons the excessive buildup of ice on the outdoor unit is an another big issue in the heat pump performance as ice buildup affects the proper heat transfer. When homeowners notice their setup is frozen, they believe that the heat pump quit working properly.
Possible causes:
- Failure of defrost control
- Restricted airflow
- Issues in fan motor
- Dirty air filters
- Leaks in refrigerator
Troubleshooting tips
- One of the best way is to shut off the system and let the ice to melt naturally
- Replace the airfilters
- Clean the dirt and debris that blocks the outdoor unit
