I stupidly obtained a heat pump for our home! I researched online about how green plus efficient a heat pump method is, then a heat pump is both heating and cooling in one system. However you save a ton of money only getting heating and air conditioning service, repairs plus tune ups on a single system! The heat pump also works way more efficiently than most heating and air conditioning units. However rather than create AC plus heating, the heat pump just uses the existing heat energy. It takes the moderate air from either inside or outside plus pumps it in or out. It all depends on if you want heating or cooling. Everybody online said that their heat pump paid for itself with multiple months of use. The people loved that the outdoor air quality is what the heat pump used. It made everything guess fresher plus cleaner. The heat pump was so extravagant to buy! But I thought that it served both heating and AC functions, so I splurged for it. I also was totally drinking the Kool-Aid. I figured I would see that a money back plus I was making a worthy investment. The heat pump is just not effective enough to produce heating for me. I live in a colder climate, apparently heat pumps can’t handle that. There is literally no heat energy for it to pump, so I basically am using a tiny portable furnace in the dead of Winter season. I am looking into adding a gas furnace to the heat pump because it is that bad. Adding another heating element will cost a ton of money.
