Troubleshooting Heat Pumps

Heat pumps are one of the essential components. They are a part of most households these days making the indoor spaces optimally and warm and cool according to the need of the season. Being a mechanical device, after all, a heat pump is subject to malfunction due to gradual wear and tear and other reasons. It is always better to troubleshoot small issues at home before seeking professional help. This way you can resolve small issues before they blow out of proportion generating unwanted repair costs and replacements. Here are a few troubleshooting tips for a heat pump:

What to do if the heat pump is not running at all?

Ideally in such cases you should begin by checking the thermostat. See if= it is set toolow in cold months. If so, set three to five degrees above the room temperature in heating mode. In summer seasons it should be set it to few degrees lower than the room temperature. If the thermostat was replaced recently, then you may not have bought a compatible model to your heat pump. Check if it has been wired correctly.

Now, switch the fan on.If the fan is not running, then check the breaker and fuses. If there is problem in the fuse change the fuse. Otherwise flip the breaker to OFF and then set it ON again. If it trips again then it is problem of short-circuit. Determine cause of the overload. The reasons could be many- loose connection, a seized blower motor, shorted controller board or worn-out wiring.Repair wherever there is problem. In case you cannot handle these yourself, seek professional help. In case the fan still does not run then it is time to see the outdoor unit.

Always check the power switch to which the heat pump is connected. It could be either on the wall near the unit or inside the air handler cabinet. In case the heat pump is integrated with an electrical unit that produces supplemental heat. These elements automatically turn on at a fairly low temperature—around 20 degrees F. When they come on, they consume a lot of power, often tripping the circuit breaker. So check if the circuit breakers or fuses that protect the heating elements is tripped or blown.

When you start checking the outdoor unit look for frost build-up near the out door coil. This A frost build up will be due to non-working defroster timer or control module, or low refrigerant level.In case there is no frost, check for debris and dust in cabinet that can block airflow. Remove grass, sticks, leaves,and weeds in case they are there.Also check to see if the outdoor fan is running. If not, there may be a problem with wiring, fan motor, compressor or capacitor. Repairing these will need a professional maintenance service.

What to do if the heat pump doesn’t heat or cool optimally

Well, you should know that heat ump cannot produce the same level of heated air as delivered by oil or gas forced-air furnaces. But in case your heat pump was delivering certain level of heated air which it is not producing currently then it is time to have a look inside the machine. But you should know that a heat pump can sometimes go into defrost mode to prevent freezing. In such situation it delivers cool air.

But otherwise you should check if the thermostat is set properly. Raise the temperature 5 degrees above the room temperature. Always ensure that the registers in the rooms are open for hot air to come in. Change the filters if they are clogged.Most heat pumps have auxiliary heating units to supplement the required heat that cannot be generated by the pump. Make sure these components are working properly. Clean the coil of the condenser unit. If doing these things does not get you a result then it is time schedule a call with a heat pump technician.

What to do if the condenser unit freezes up?

The condenser unit sometimes freezes up. The reason could be extreme temperature or the thermostat set too low. Thebes way to deal with it is to turnoff the heat pump for some time. Now check if the return-air registers and the filters are blocked. This could also be due to tripped breaker in the supplemental heating unit. If they are fine, then it is better to consult professional.

What to do if the heat pump does not cycle properly?

This is a problem that can lead to skyrocketing power bills and also rapid wear and tear of heat pumps. The causes are generally malfunctioning blowers or clogged filters. If both are fine, then check the thermostat. It may not be calibrated properly. It could be located wherewithal is unable e to sample the room air. However, if it has been there since long and was functioning smoothly before then that is not the issue. Calla service provider of heat pump repair insomuch case.

What to do if the heat pump makes noises?

This is a very common problem in heat pumps. If you hear squealing or grinding noise immediately give service call to maintenance service.If you hear rattling sound, ensure that the screws in cover panel are secured tightly. Rattling sound could frolicsome duct work. Loose particle sin the air handler could be its cause. Metallic ducts conduct noises from the air handler unit to your rooms. The solution to eliminate the noise is to have a flexible insulation duct work inserted between the heat pump and the duct work runs. This can only be accomplished by heat pump contractor. Sometime pinging and popping sound is heard which is due to thermal expansion. Air passing by wobbling flaps of metals can also generate such noises. You can as top it by making a small dent in the sheet metal. This will make it more rigid that is less likely to move when hot or cold air passes by it.
