Heat pumps are refrigeration systems similar to air conditioners but with more accessories and controls to enable them to heat as well as cool. Heat pumps are more complicated than air conditioners. This why it is critical that your service provider have a keen understanding of the refrigeration process as well as the controls involved. An incorrectly operating heat pump can run your electric bill very high. Singer Heating and Cooling is your NATE certified heat pump repair expert.
A When operating in the heating mode, a heat pumps outdoor coil will be approximately 20 degrees F below the temp of the outdoor air. If it is 40 degrees F outside, the outdoor coil will operate at approximately 20 degrees F. Condensation will accumulate on the outdoor coil and frost will form. This frost will form a blanket over the coil that will prevent air flow and heat absorption. Heat pumps will enter defrost cycles to melt the frost blanket.
A If your heat pump is low on refrigerant, it won’t be able to put out much heat at all. This will mean that the auxiliary heat will be doing most of the heating. The auxiliary heat cost approximately 3 times as much per unit of heat as the heat pump does. You may not notice the problem until your hi electric bill arrives after the first cold month of the heating season. The reason that this often happens is because the auxiliary heat will keep the house warm.
A. If the unit is approaching 10 years in age and needs the replacement of a major components such as the compressor, reversing valve, indoor or outdoor coil, it would be advisable to replace instead of fix. Most new heat pumps come with a 10 year part warranty covering the whole machine. Repair warranties only cover the part that was replaced.
A Generally, the average life-span of a well maintained heat pump is 12-15 years, but individual units may vary and some last much longer. An AHRI survey showed average heat pump life to be about 14 years when recommended maintenance procedures were followed.
A In most cases, no. Heat Pumps operate on a 240 volt circuit. Severe shock or electrocution is possible without a thorough understanding of electricity. The refrigeration cycle of a heat pump is more complicated than a cooling only air conditioning system. Many service technicians lack the knowledge required to diagnose mechanical and control issues on heat pumps. This is not a good DIY project.
A No that would be poor use of energy. A heat pump can provide efficient usable heat as log as the outdoor temp is above 0 degrees F. The heat pump and the electric auxiliary heat work together – automatically. Emergency heat should be used for temporary heating when experiencing problems with the heat pump.

A Standard one-inch air filters should be checked every month during peak use, and replaced if it looks dirty enough to impair the air flow through it. Some filters, such as electrostatic filters or electronic air cleaners, are washable; others, such as media type air cleaners are disposable and must be replaced, but many of those are designed to last up to six months, even a year.
Q My heat pump’s compressor hums and dims the lights in my house but does seem to be running. What causes this.
A Your compressor may be hopelessly locked up but more commonly this is the caused of a bad capacitor or starting component. There are other potential causes that an experienced technician can diagnose.
