What can we do about our homes over sized heat pumps? The heat pumps in our home are oversized. They cycle on and off too often. The house is cold and clammy.

The compressors have two speeds and the fans have variable speeds. Any advise would be appritiated.

Do you know a way to calculate the savings when comparing heat pumps? I've heard heat pumps usually last about 15-20 years and mine is now 16 years old, but running fine.

Would it lower my utility bills enough to justify upgrading?

I need a new air conditioner and furnace. Are the new heat pumps really better? I live in Indianapolis and remember how bad heat pumps were in the 70's and 80's. Thanks for your help. I want to thank all of you for your input. We are going with a 16seer system since we do only average 8 days a year below 35 degrees. The old system was installed in 1979, so I expect to see real savings. you have made my decision easier.

Do I need two heat pumps to heat and cool my house? We are currently putting a 576 square foot addition on our exiting 125 year old farm house of 900 square feet. My contractor tells me it would be cheaper to install a 1.5 ton heat pump in the addition and a second 2.5 ton pump in the original house rather than try to get one pump to service the whole house (original + addition). This doesn't sound right to me. Does anyone out there have any knowledge or experience that might help me on this? Thanks.

How much heating power? And what about heat pumps? Hi! I have a ~700sq feet house and temperature here goes down to 32-50F for barely 3 months a year. The rest of the time it's way hotter. The house is reasonably well insulated. Does anybody know more or less how much *heating* power - in kW, btu/h or whatever unit :) - is needed here? What is your opinion about heat pumps as a solution? Have you ever used them, do they work fine? Suggestions? Thanx!

My heat pump quit working and now I am using small space heaters which seem to heat my home better than the heat pump.

I don't want to make my electric bill sky rocket, so I am trying to decide whether to go ahead and get my heat pump serviced or to wait and keep using the small heaters.

What is the COP of heat pumps which are in use presently? By the second law of thermodynamics work has to be done to transfer heat for a low temperature region to a high temperature region. This happens in a refrigerator. The COP is the ratio of heat transferred to work done. Heat pumps are possible(at least in text books) which tranfer heat from low temperature ambience to high temperature enclosures. If they are in practical use what is their COP

Do heat pumps replace a furnace? Currently, my house has a forced air heating system being run off a furnace that's in a 4-foot crawl space. The cooling is through in-wall AC units. I'm a little nervous about carbon monoxide spreading, both under the house through the open area crawl, or through the forced-air ducts. I'm looking into getting a heat pump. If I also get an electric tankless water heater for my hot water needs, will I still have a need for the furnace or can I remove or disable it? Also, I read the existing duct work can be used for the heat, but is it really efficient to have the cool air coming out of the floor also? Thanks.

Heat pump will not cool, only pumps out hot air. Any suggestions? We have an air to air (i.e. not ground source) heat pump with additional heating coils.

Does anyone have and personal knowledge of "packaged unit" Heat pumps? I've had several recent quotes to install a heat pump in my home and several of the companies have quoted a packaged unit instead of a seperate outdoor unit and indoor air handler.

Any input would be appreciated.

Are heat pumps a good choice in Central Alabama? I'm buying a new house around Montgomery, but most of the listings I see for new homes have Heat Pumps instead of Gas/Electric. I've heard that Heat Pumps don't do as well, and if I'm buying a home, I want it to be comfortable. I'd hate to get duped by a builder who says 'These things are better because...' and then find out he just got a good deal on heat pumps or gets subsidies for using heat pumps and is just trying to push them off on people.

is there any website that shows wholesale or retail prices for central air conditioners / heat pumps ? My Trane split system heat pump is 18/19 years old. starting to do to many repairs on it..would like to replace it this winter..would like to shop around to compare quality and cost so that when I do get vendors to give me quotes I will a least have an idea what I'm talking about..I am not having much luck finding a place on the web. It seems that nobody wants to tell you what the real prices are.

What are heat pumps used for? what uses a heat pump? what has a heat pump in it?

Are heat pumps used and well known about in your area? Heat pumps of different types are being used with big success in Sweden where I live. Despite our rather cold climate it works very well and has drastically reduced the average household's use of other energy sources for heating our houses and is also economically beneficial for those who choose to install them. (They can also be used to cool the air.) Is it being used where you live? If not what do you think is the main obstacle from using it? For more information please check this site: http://www.heatpumpcentre.org/ Afratta: I live in Sweden and our winters can be cold. There are heat pumps that works even down to -20 degrees Celsius. Also, you can use heat pumps that recycle the heat in the air indoors which is already heated. We are using that in our house and it works extremely well. For your convenience: -20 Celsius equals -2 Fahrenheit and 45 F equals 7 C Afratta: I do appreciate you sharing your knowledge, thanks. Yes, you're right that heat pumps can't work as the only energy source in cold climate but I don't see why that would stop us from using them (as long as they are beneficial for our economy and the environment). The heat pump we use at our home (the one that use the heat from the air inside instead of from outside) approximately saves us 7000 kWh/year. The need for oil within the Swedish building and services sectors has decreased with 70% since 1983, partly because of heat pumps. Also, we both know that market economies are great to find solutions to a need, and the development of heat pumps are moving forward in a high speed.

Why are heat pumps not used more, instead of windmills, wave machines, etc? I heat my swimming pool and house with a heat pump. The Queen has heat pumps at Wndsor Castle.

Surely the best way forward to combatting global warming is to COOL it? Why are we faffing about building windmills and ruining our countryside?

comparison american standard heat pump vs. trane heat pumps?

Top 5 heat pumps? Anyone know? My heat pump which is used to both heat and cool my home is 15 years old and will soon need replacement. I would like to know the most reliable and reputable heat pumps brands that are available. I am told that since my system uses freon, that both the outside heat pump, as well as the inside furnace unit which partially uses the heat pump for heating in winter, will need to be completely replaced because it uses freon which already is, or will soon will be, banned for environmental reasons. The inside furnace unit runs on an electric coil strip to add the extra heat which the heat pump cannot supply when it gets too cold outside in the winter. Will the entire set up need to be replaced? And what would be the approximate cost of this total replacement? Thanks...
