All prices are fairly close.. Must be about right for your area.. Are these R22 systems or R410 ? I would suggest a 90+ furnace instead of the 80 shouldn't be alot higher in price.. If you have to upgrade any venting with the 80 you may break even with a 90...

Doesn't look like real bids.

A 10,000 sq. ft. single story home? Is it a warehouse? Is that number accurate?

If so, it seems like a commercial system might be the right one. Get the highest efficiency system. And certainly, seal and insulate that warehouse.

From the equipment size I'm guessing he meant 1000 sq ft. The bids look typical. Why not go to 90%to 95% efficiency units? Gas isn't going to get cheaper.

Looks like they intend to use the heat pump for primary heat and the furnace for backup hence the 80% mid. A heat pump and high efficiency would be redundant. Where do you live Wayne?

I would check the utility rates see which is cheaper in his area to operate. If gas would be cheaper I would just go all gas with atleast 90+

More Info
Hi All, I meant 1,000 Sq. Ft. The bids are real. I live in Richmond, VA. The heat pump would be the primary source; furnace for very cold periods. Thanks for everyone's help.

I would talk to your electric utility and see if they have a cost analysis for heat pumps and electric strips for supplemental heat vs heat pump and gas furnace vs 92% high efficiency furnace with standard A/C unit. Heat pumps lose efficiency at the lower temps and require more backup heat. A standard furnace and A/C in the long run may be a lot more reliable. Most heat pumps are used with coil blower/airhandler units with electric elements for supplemental heat. The heat from a heat pump is usually cooler and less comfortable. We cannot comment on pricing very well as it varies greatly from city to city, state to state. Personally I would buy a Lennox G71MPP or G61V furnace with high efficiency ECM motor and a XC15 SEER airconditioner. Incredibly smooth,quiet matched set and VERY efficient together. Will cost less to run those 2 than any heat pump combo.

How much yard to you have? Have you considered geothermal? Tax incentives make it competitively priced. And you'll use ALOT less energy to heat/cool your home!
