A heat pump that runs without making your Del City home comfortable can have an airflow, control, electrical or refrigerant problem. The same equipment handles heating and cooling, so a fault may affect one mode or both. ARP Heat And Air serves Del City from our Edmond office and can help you find the cause before you decide what to do.
Start with a few safe checks
Confirm the thermostat is set to heat or cool, as needed, and that the temperature setting calls for the system to run. Set the fan to auto if you do not want it circulating air between heating or cooling cycles. If the thermostat uses batteries, check them. A heat pump may deliver air that feels less hot than air from a furnace; that alone does not necessarily mean it has failed.
Check the return filter and replace it with the correct size if it is dirty and you can safely reach it. Make sure supply and return vents are not blocked by furniture. If a breaker trips repeatedly, do not keep resetting it. Turn the system off and call for service. Do not open electrical panels or handle refrigerant lines.
Some frost and brief steam from the outdoor unit during a winter defrost cycle can be normal. Heavy ice that persists, especially with poor heating, warrants a service call. Turn the system off and do not chip the ice away or pour hot water on the unit.
Safety first: If you smell gas, leave immediately without operating switches, then call 911 and your gas utility from a safe place. If a carbon monoxide alarm sounds, leave for fresh air, call 911 and do not reenter until emergency responders say it is safe.
How we diagnose a heat pump that is not working
We start by asking whether the problem occurs in heating, cooling or both, and whether you have noticed unusual noises, ice or a change in airflow. We check the thermostat settings and controls, indoor blower, filter and accessible ductwork. We also inspect the outdoor unit and test electrical components as appropriate.
Depending on what we find, we may check the reversing valve that switches the system between heating and cooling, the defrost controls, and auxiliary or backup heat if installed. If measurements suggest a refrigerant problem, we investigate the cause and discuss leak repair and the correct refrigerant charge rather than assuming the system just needs a refill.
Repair or replace?
A failed control, capacitor, motor or another isolated component may be repairable. If a major component has failed or the system needs repeated repairs, replacement may be worth comparing. We consider equipment condition, compatibility, available parts and the home's heating and cooling needs. A replacement assessment can include airflow, ductwork and electrical requirements, plus backup heat where appropriate.
We explain the findings and discuss the proposed work and quote before you decide. After an approved repair, we check system operation as conditions permit and explain any remaining concerns or next steps. If a part must be ordered, we will discuss that with you.
