How is the heat pump supposed to work? I live in a 1996 Double wide mobile home. We have the A/C pump outside and the furnace is inside. I was just wondering does anyone know is the A/C (outside unit) only supposed to come on when the A/C is on or is it supposed to work when the heat is on too? I was thinking the furnace (inside) heat strips heat the house and the A/C unit (outside) cools it but I just wanted to make sure. My heat is working fine but the past 2 months my electric bill has been outragous!!!! We are using way more kilowatts than this time last year and it's warmer this year. The heater seems to be functioning properly though. Just thought I'd see what anyone thinks about this. Thanks for reading :-)

How much does it cost to install a heat pump to replace a 36-year old HVAC system for a 3-bedroom house? The existing system uses natural gas for heat and a split indoor/outdoor system for the A/C. The new system would use a heat pump, whose outdoor coil should be underground to avoid being affected by freezing air in winter. The heat pump should be efficient enough to not need any secondary heating system, but just use the heat pump all the time, even on the coldest days, which should be possible because of the underground coil.

On a split unit heat pump, is the fan on the outside unit supposed to turn? I have been paranoid about my heat pump since I bought my house a year and a half ago. When warmer weather came, I switched the thermostat from heat to cool. Air comes out of my vents and the thermostat does kick off when the temprature reaches the marked level, but my house does not get cool. What generally happens is the unit (in the attic) runs until it gets dark, outside cools down, and the temp. inside then cools. The ouside unit doesn't seem to work at all. It has been so long since I used it last year I don't remember if that was what it did last year. Any ideas before I spend $$$ getting someone out to look at it?
What temp to keep heat pump at? I have a home I only use on weekends. which has a fairly modern heat pump. I have heard that I should keep the temp the same during the week when I am not there as on weekends as this would be more energy efficient since the emergency heat would not be needed. Up til now I have been dropping the temp to 55 degrees during the week and then bringing it up when I arrive on the weekend. I am located in the Carolinas where it does really cool off during the winter. Which do you think uses less energy?
