This winter I installed a Mitsubishi Air Source Heat Pump (27 SEER) in my home. I was told they will work down to -13 degrees F, My system worked perfect down to my lowest temperature of -4 degrees F. Airsource HEAT PUMPS ARE GOING TO CHANGE THE WAY WE THINK ABOUT HEATING AND COOLING.
They are cost-effective, it costs less to operate than Oil, Propane, or Electric.........They Heat and Cool.
They are clean and quiet.
One day installs.
To put 100,000 BTU of energy in a home it costs.
$5.00 with electric resistance heater but only $1.70 with an ASHP.
Same with COOLING it is 3X LESS to run an ASHP (27seer) than a 9 seer window unit.
