While most heat pump repair jobs should be left to the professional, homeowners should know and understand some of the more common problems that can occur with these systems. If the unit is experiencing a simple problem, it may be possible to diagnose its cause and restore the HVAC system to operating order without a service call. However, with more complex problems, the best solution is to call for the help of a certified HVAC professional.
During the winter, when a system stops heating one's home, owners should start by taking a look at the thermostat. It is possible a family member has bumped this little device in the hallway and caused a problem while unaware of the trouble. If the thermostat is set too low or in the cool or off position it will not provide the warmth needed. Thermostats must be set above the current temperature or it does not start. For diagnostic purposes, set the temperature 2-4 degrees above that in the home and ensure the fan is in the on position.
Once the unit's thermostat is set, the air handler should be operating loud enough that it can be heard and the air should exit the vents. If the fan did not start, one may have a tripped circuit breaker. If the breakers are ok, the thermostat may need replacing or the system's low voltage wiring may have a problem.
If the fan can be heard running, it is time to turn the thermostat so the emergency backup starts. It should be set five or more degrees above room temperature. Give the device a minute for the electrical heating coils to warm and check at the vents. If the unit is now producing, the problem is likely located in the outside unit. If not, the problem may be the thermostat or something happening inside the air handler.
Lower the system settings to two degrees above the room's current temperature before heading outside. Wait a couple minutes before proceeding. Ice on the unit may indicate refrigerant level problems.
When outside, you should note the fan on the unit to be running. However, it is possible for the device to have a thermostat to have a thermostat to prevent it from operating in extreme cold weather. If temperatures are above freezing, the problem may involve run capacitors, the fan motor or wiring.
A final check for the homeowner is to operate the system through its normal heating cycle. Air entering the room should be 15-20 degrees warmer than that that is leaving. A smaller temperature difference could indicate a problem and that the unit needs repairs.
While home occupants may find it possible to make a few simple repairs, including replacing a thermostat with a digital model, most heat pump repair jobs require the help of a qualified HVAC tech. Home occupants can ensure the system provides the longest service by changing filters regularly and scheduling preventative maintenance for the unit every year. As such devices provide both heating and cooling, they receive very little break in usage. With preventative maintenance, they can have a longer life and provide many years service.
