Heat pumps are a popular option for central heating in the home. This total electric method offers two types or stages of heat – one generated by the condensing unit/heat pump outside and electric heaters installed in the air handler inside. One of the most important markers for a heat pump’s heating efficiency is the HSPF (Heating Seasonal Performance Factor). New equipment has an HSPF that ranges from 8.0 to 10, with 10 being the most efficient.
Knowing a little bit about how your heat pump operates can save you the cost of a service call during the winter months. Let’s take a look at common issues that arise from a heat pumps standard operation:
- My outdoor unit is making a loud “whoosh” noise: if your system is running and heating normally, other than this “whoosh” noise that occurs from time to time, then you are probably just witnessing your system running in the standard defrost cycle. During defrost, the fan on the outdoor unit stops running, the reversing valve switches over, followed by the “whoosh” sound, and the compressor runs in cooling mode. It does this in order to build a higher pressure outside, and melt any frost or ice that may have accumulated on the coils. You may also see steam coming from the top of the unit. This is normal. No need to worry, as long as your system is otherwise heating properly.
- My thermostat says “aux” or “emergency” heat: this means that the auxiliary or emergency heat strips have been activated. This is due to a large variance in the set point on the thermostat versus the temperature reading in the room (generally, more than 2-3 degrees). Make sure that the thermostat is set to “Heat” and not “Aux./Emer Heat.” If the thermostat is accidently switched to emergency heat, the heat pump will not generate heat, only the heat strips. In the case of an emergency, this may be okay; but it can get expensive to heat only with electric heaters if your heat pump is running normally.
- I’m not getting enough airflow: this could be due to a clogged filter. Make sure your indoor fan is off, and check to make sure your filter is clean. A clogged filter can cause your system to freeze up, lose airflow, and diminish its heating ability. We recommend changing your filters once per month, as needed.
- The display on my thermostat is gone/my system won’t run at all: if your thermostat display is out, or you turn your heat on and nothing happens, check your breakers. If the breakers to your system are tripped, it will keep your system from running and in some cases cause the thermostat display to go out. If you do have a tripped breaker, we commend calling us for an inspection of possible causes
