Hi: Last week, a contractor installed the above-mentioned new 16 seer heat pump, an air handler and a heat kit. Our house has 3 levels, each about 800 square fit. Initially the house would not heat above 56 degrees. Therefore the contractor drained 2 oz of Puron gas from the line, then decided to put 0.5 oz of Puron gas back in. The temperature is now rising to the desired temperature. However, it seems to be rising rather slowly, i.e. 1 degree per hour while utilizing the auxiliary heat (which he said costs more to run). What can be done to minimize auxiliary heat and see the temperature rises fatser? Thanks.

That is worrysome about putting refrigerant in hap hazzardly... There is a math style process involving pressures and temperatures in two locations that dictate how much ref. goes in. Anything else shows clueless installer. Too much or too little ref. will not work correctly.

Heat pumps do not work below about 33 degrees outside temp. Above that them, aux heat should not be coming on...

You would need to verify that the system you have is rated for the space that you are trying to heat...

Heat pumps heat more slowly than gas or electric, so using set back thermostat is not recommended. True economy comes from maintaining constant temprature. System has to work to hard to raise the temprature, and eats up savings in efficiency by allowing temp set back.
