We moved into our house about 6 months ago and the heat pump recently died. Since we were running on aux heat and a bit overwhelmed with such a big expense we got a few quotes and had a new pump installed right away. Luckily, I did have time to do some research and hopefully made a decent decision.
That all said, I am still anxious to see how the new heat pump works out. There are certainly many horror stories online and I hope we never become one of them. I am also worried we won't see any monetary benefits from the change - that's the only potential upside to laying out such a big expense.
My question is, how many we get the most out of our new system as far as reducing our utility bills? For example, I read somewhere that turning down the heat too much at night can be counter-productive as the aux heat may have to kick in to get back up to higher temps at waking time?? I know heat pumps have their own little quirks so I want to try and run ours as efficiently as possible so any advice is greatly appreciated.
Background: We replaced a Carrier FV4ANF003/38YXA042 (3.5 ton, 10+ years old) with a Carrier 25HPA6/FE4 (4 ton) with Infinity Thermostat with a 10 yr parts&labor warranty. We live in Southeastern PA.
