I need a new air conditioning unit and am considering changing to a heat pump on the advice of a HVAC contractor.

Could I get an unbiased opinion please? The house is 11 years old, a builder grade insulation package and 2300 sq. ft. The ceilings are fairly high and I am cold every winter as the heat goes to the ceiling. Doesn't seem to matter much if I get space heaters. Anyway, he says if I add a humidifier and do the heat pump it will be less heat bill and more comfortable. But my cost goes from $4400 to $10,000. As I will only live in the home 3-5 years I don't think I will recover the difference. Comments? Thanks!! And do I really need a Trane or can a lesser quality unit suffice since I really don't want to invest for the long term?

    This also depends on what you plan on doing when those few years are up. I assume you plan on selling the house? If so, you should consider the potential effects/impacts this decision might have on the resale. If you buy something cheap, sure you may save a few thousand now, but that might cost you in the end when a buyer asks for an "allowance" in order to replace a cheap unit.

    You might also consider not going with the heat pump and instead spend a portion of those ...»

    saving on upgrading/adding to the insulation in the house.

    If you are cold and install a heat pump in GA, you will not get more comfortable especially by just adding a humidifier. I would upgrade your insulation, air seal the house then replace the unit with a new high efficiency furnace. If you do an energy assessment through GA Power (the paid version), they require a payback analysis in order to get the rebates. In your case this could save you a lot and get you rebates as well.- visit www.whyitpaystogogreen.com ...»
    to see a list of the rebates that are available. We can help you or I can recommend help based on the findings on the energy assessment.

    PS- the things that save you the most on energy savings typically don't cost as much as new mechanical equipment.

    Annie,

    I have lived from Rhode Island to Florida and back again several times. If I am cold in my house over the winter, a heat pump alone is not what comes to mind to fix my problem..... "Toasty" warm and "heat pump" do not belong in the same sentence....there is much more to it than that.

    I would take Sawhorse up on his offer. ...»

    Trane is one of several quality manufacturers...but keep in mind most manufacturers have good, better and best systems. Don't get sold on a brand name for namesake only... Tim

    Yes- the house needs to be designed as a system. The only reason to add a humidifier to to raise the relative humidity to 40% or more in the winter. It will make you feel more comfortable, but will not lower operating costs.

    Thanks for some great input. We are not on GA Power here in our part of Gwinnett Co. so that may have an effect on possible rebates. I'm still wondering if one method of heating is more efficient than another, i.e. gas vs. electricity in this area and if I just need my a/c replaced that would exclude heating, right? The only reason to include a furnace is to make my system more efficient? Any way to calculate payback? Thanks bunches for all the expertise!

    Annie - your probably have Walton EMC? You've got good advice....I'd get some other quotes on systems as well. If you're cold now with gas heat...you'll feel even colder with a heat pump...even if the temp registers the temp you want. The others can explain better than I can why this is...having had both....I prefer my gas heat and just pay the bills. You can always turn the system down and get a programmable thermostat so you can set a schedule that saves you some money. Don't go ...»
    cheap on the system but there are some "scratch & dent" deals out there. Check with you power company for rebates as well...sometimes they also offer special financing to their users for upgrades.....

    I would do the following. Get a home energy audit done.

    Heat pumps in Fla are great things as during the heating season most of the lows are well within a operating mode that does not require the aux heat to operate.

    However, simply putting in a heat pump will not solve your problem. Heat pump temps are much cooler then that of a gas or electrical furnace output. Sometimes by as much as 40 degrees. And if ...»

    you feel that your not warm enough now, its not going to do a whole lot after this install.

    Adding a humidifier will help a bit. But with heat pumps you need a power unit that may also require heating the water to it to allow for enough humidity to be created. These units are expensive both to purchase and to maintain.

    As far as Trane, Carrier, Lennox and bunch more. They are all great. But can also not work correctly if they are not installed properly. The installation of the system makes all the difference in the world. So no you do not need to purchase this manufactures system.

    Having an energy audit done will provide you with a lot of very useful information about your home. Not only how to make it more energy efficient, but how to make it more comfortable. They will pinpoint out where your loosing your money and where you need to spend it. They can also size the system for the house for you so your not putting in a system that is over sized for you home.

    In addition the audit should be able to provide you with some insight on payback times based on where your putting your money. Once you have this information you will be able to determine what system and expense makes the most sense for you and your wallet.

    Great post Bob.....if you go with electric to save money....just wear lots of sweaters and sweatshirts! If you want to "feel" warm...stay with gas.

    Sorry but if you are already having trouble heating the house a heat pump Will Not help, humidifier or not. Second....why are you replacing an 11 year old system? Try a good humidifier on what you got now before you spend thousands. We could install a Honeywell True steam for just over a thousand dollars and it would probably alleviate the problem. Lastly, Ten grand is crazy for a system, they better be quoting you for something top of the line for that much whether it's a Trane, heat pump ...»
    conversion or not. We are out of Snellville and we would be happy to give you our opinion and a free estimate. You need to have the system there now evaluated and I would be happy to try to save you money if possible.

    770-918-8187 ask for Ian to come out if you would like to give me a try.

    Didn't read the posts till after I posted, I agree with all here and honestly if you want a more rounded solution Sawhorse may be more helpful as I cannot advise on insulation and sealing the house.

    Just a quick note on your "Builder insulation package". In building homes and additions, there is a specific "insulation inspection" The building inspector looks for R values and voids. And if they are not up to code, the inspection is rejected.

    R values today are R19 floors, R13 walls and R38 in ceilings. When I started they were not required in floors, R 11 in walls and R 19 in ceilings. Codes have done well at keeping up with ...»

    insulation requirements.

    I would suggest spending a few thousand dollars and upgrade (only because time has dictated higher R values) your attic and floor (if applicable). Easy enough and great peace of mind.

    I replaced my Min seer heat pump with a new min seer heat pump last year and (only from new equiptment) have seen my heating and cooling costs cut in half, here in Virginia.

    I did upgrade my floor and ceiling insulation to R19 and R38+ respectivly a few years back.
