What is the temperature range for my Heat Pump?
The Coleman-Mach heat pump is an effective heat source, as long as outdoor temperatures are above 45°F. Below 45°F, there is not enough heat outside for the system to absorb, and efficiency drops. With a lack of heat, you will run into a freeze up situation that will shut down your compressor, but leave the indoor blower running. We recommend that, if you know your outdoor temperatures are going to be below 45°F, simply heat the application with the LP furnace until the conditions are more ideal for the heat pump.
