If your residence has a heat pump system that offers cooling and heating, it may seem like there are numerous probable reasons when something goes wrong. Heat pumps do function differently than your usual air-cooled air conditioner.

So, what do you do about heat pump problems?

Heat pumps are resourceful, but even they have their labors in frigid temps. When wind chills get down low, you may find that your home is chiller than the thermostat and the only real fix is to wait out the deep freeze. Though, in average temps, your heat pump should work as it should.

One vital measure to take is to make sure your house is sealed up correctly, and that hot air is not seething through gaps near windows and doors.

Beyond this, it’s best to call a professional HVAC repair technician because the heat pump problem could be any of these:
Faulty valves (reversing, compressor, etc.)
Faulty thermostat
Dirty unit
Leaky ducts

The outdoor part of the heat pump has to withstand icy conditions, and frequently it gets iced up when there are bitter cold temperatures and extreme moisture. The unit has a default mechanism built into it (defrost cycle) that will ice off the heat pump and melt the snow.

If you see that ice has formed, it’s probably because of a defective defrost cycle that will need to be handled by a specialist. You can help relieve the stress on the defrost cycle by making a barrier around the unit to shield it from snow, ice, wind and to consistently clear off ice and snow in the wintertime.

Pump Doesn’t Come on At All
First, you need to make sure that the furnace hasn’t been cut off by accident.

Next, you need to right all the circuit breakers linked with the heat pump, even if they don’t appear to be tripped. Finally, you should check for any worn wires in and around the air handler, heat pump, etc. If no clear sign of wear is detected, it’s best to contact an experienced Rochester heating and cooling expert.

Pump is Making Noise
The pump will have a little noise associated with it as it operates. But, grinding, rattling, or squealing indicates something is off. Remember, a system makes a little noise, but if it is prominently loud, there’s probably wrong.​
