        Lots of folks in Arizona have them. They work great until it gets cold. There are complaints starting at about 35 degrees (OK our blood is thin here!). They don't seem to work well at all at low temps. We had five nights last year that dropped in the 20's and the outcry was loud.
        But I was very happy in my gas heated home. No issues.

        A simple way to picture how a heat pump works just picture how a window A/C works.
        Cold goes in, heat goes out. Now add a reversing valve in the Freon line. Then the heat goes in, cold goes out.
        Since your building a new home you have the options of building it above minimum code as far as insulation and sealing goes so it would take less energy to heat and cool.
        In your area I think I would choose the gas back up packaged unit instead of what's called a split unit.
        The difference is gas heat would kick in instead of electric powered heat strips if the unit can not keep up when it gets to cold.
        What's other people using in the area where your building this home? Why not ask them how what there using is working out?
        All my homes in VA (3) have heat pumps and all have worked out fine.
        One thing we have done is installed a back up source of heat in all of them. More for use as an emergency heat source of heat in case of loss of power then to supplement the lack of heating.
        Adding a propane or natural gas fire place in your home design can look nice and give you that extra boost of heat if it's ever needed.

        Heat pumps are widely used in my part of the south but only if your neighborhood doesn't have gas available. If you have gas, I'd use natural gas over any other form of heat.

        I had a heat pump in my first house in Pennsylvania. It was a 1800 square foot townhouse and when I built I had a chimney put in so I could put a wood stove in the basement. During the cold of winter I used wood. The heat pump was an upgrade that gave me AC, the other units had baseboard electric and no AC. Except in the mountains of PA AC is about mandatory in the summer. My neighbors that didn't pay the extra $2500 for the heat pump (1984) really regretted it in July and August.

        Heat pumps as mosternaz points out work fine until the temperatures drop below about 35F then the "emergency" heat kicks in which is usually electric resistance heat. The air coming out of heat pump ducts tends to be cool to the touch, where gas fired furnaces put out air that feels warm to the touch. In the case of heat pump the air might be 75 degrees, cooler than your skin temperature so it feels cool. Whereas a gas furnace will put out air that is warmer than your skin temperature so it feels warmer.

        If you don't have gas available I might consider a heat pump with a propane back-up. If you have gas, I'd go with a gas furnace and an AC unit. Gas packs are pretty common here in homes with with low crawlspaces but they are gas furnaces and air conditioners in one unit, not a heat pump. They tend to have a shorter life than a gas furnace in the basement or crawlspace and a compressor located outside.

        Any advice given here is general in nature and is not necessarily valid for your given area. If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.

        My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.

        yes...i think a BOILER AND A HEAT Exchanger for water would be the way to go..if i did not have to have ac.i would go hydronic heat...base board heaters, little higher up front, but saves in the long run

        Heat pump heat is not warm. If you like the feeling of warm air out of the ducts, go with a gas system. Since you have nat gas available it should be a no brainer - gas will give you warmer heat for less money.

        Remember you are in the South - your AC will be as important as your heat. Go with a combined forced air system - gas heat and heat pump cooling. Best comfort for the buck.

        My gas pack and A/C unit does a great job. My gas bills are next to nothing, even in the "dead of winter' (my Iowa relatives are smirking as I say that.
        I've never heard of anyone here who liked their heat pump when it got cold.
        I've got a gas dryer, water heater and range as well.
        Good luck!

        thanks for all responses,, i am looking into a nat gas fired direct vent boiler for hydeonic baseboaed heating as well as a zone to take care of hot water needs with sane boiler and then have a total separate a/c unit,,in the event of a replacement issue in future it would be one or the other instead a complete unit,,, thanks again!
