We had the above unit installed last spring in our 30 yr old two story home in Central PA. I was told to expect a 30% decrease in my electric bills in the winter since the old system was electric ceiling cable type heat. My bills have actually been higher this year than last by at least 10%. Admittedly it is somewhat colder, but along with the Heat Pump/AC we installed Pella windows and a Pella sliding glass door. All of our windows have been replaced over the last 3 yrs. I have installed a new storm door on the front door. I am using on average 500 KW hours more each month than last year. It went from around 3400 to 3900 KWH over a 30 day monthly billing period. I have had the Heating guy out here twice and they insist eveyrthing is working normally. They are a well respected local contractor who have been operating here for 30 yrs or so and were recommended by my general contractor when we had the work done.
Also, the compressor makes a lot of noise when turning on, like a vibration type noise.
Am I experiencing normal heat pump operation or has this unit had issues? I am very disappointed with the heat. It was fine during the A/C season.
It is just my wife and myself, nothing else has changed and we have the thermostats set at 68! Most of the time we are cold.
Any help would be greatly appreciated.
