Personally I am a firm believer in the heat pump. Of course, I live in central Florida where we see the mid to upper 20's a few times a year. As compared to electric heat the economics are a no brainer. I've had success using a time delay on the blower fan to allow the evap coil to get hot before the air starts blowing.
I recommend them to MOST customers with electric heat strips.

that time delay is a scary thought, because on the days where the temperature is just cool enough to run the heat pump
your compressor is straining due to excessive high pressure which can be dangerous as well

I agree with several previous posts about improper installation, and mis-information to the end user.
Heat pumps can save a great deal, sized properly, and controlled properly.
Making sure customers understand the limitations of HP's goes a long way.
Fluctuating gas and electric prices make the economic balance point a crap shoot. Had a customer with LP as back up, and he wanted to know to the penny what his balance point should be. Told him let us know each month what his electric and LP prices are, and we could give him that info. He dropped the subject pretty quickly.
As far as what we have installed, customers have been pleased with the savngs and performance.
We don't promise huge reductions in utility bills, and if a system is blowing cold air it's not the HP's fault. We go there and fix the problem."Hey Lama, hey, how about a little something, you know, for the effort." And he says, "there won't be any money, but when you die, on your deathbed, you will receive total consciousness." So I got that goin' for me, which is nice. - Carl Spackler

And that time delay thing isn't a good idea."Hey Lama, hey, how about a little something, you know, for the effort." And he says, "there won't be any money, but when you die, on your deathbed, you will receive total consciousness." So I got that goin' for me, which is nice. - Carl Spackler

Now we did the numbers for my father that lives in the el dorado hills above sacramento with a propane fired central furnace, and it does make sense, we put in an 18 seer a/s hp with a 92% furnace and his return on investment is like 3 years. (of course he didnt pay retail for the equipment so its a bit quicker then average)
The other great thing about duel fuel which rids yourself of a complaint of hp systems is quick defrost and when in defrost you can be putting alot of heat over that coil so you dont get cold air out of the vents.
As far as heat pump systems here, we've found that the reason people dislike them and how we can fix them is improving the building envelope, to many people here have poor wall insulation or large single pane windows that are leaky and pull heat out of you, these people are always comfortable with gas fired furnace because they feel the draft ontop of them and theres no defrost mode nad this counters all of the radiant heat loss there bodys get from the walls and windows. So you couple the poor windows and walls, with a heat pump that doesnt have a high temp split, and the occasional defrost, its going to make them uncomfortable.
And on the bonus you can downsize the system after you tighten up the house.
I really need to get into the window and insulation business with how much I talk about improving that instead of putting money into a higher efficency furnace.Global Warming or: None like it hot

How many times must one fix something before it is fixed?

I’ve got a 10 year old 4 ton heat pump (york). I have no complaints. Gas is not an option because the line that runs down my street stops 4 lots from my house. It frosts up even in central Florida’s mild winters but I just spray it down with recycled rain water (red neck water source heat pump). When this old unit dies I’ll probably go with a climate master gshp with vertical wells.

Here in Minnesota with off peak power at $.05kw and nat gas at $1.15 a therm or propane at $2.10 a gal. Heat pump is a no brain er. huge savings. We use Carrier Infinity set lock out at 15-25 degrees depending on balance point and comfort. Back up is a 95% Carrier Infinity furnace. I have had great feedback on savings.Aint Notin Sweeter, Then A Brand New Heater!!!!!!!!!!

My most satisfied customers are those with geothermal heatpumps...Genius = The guy who can do anything...except make a living!

The main problems I see with customers complaining about their HP is, the system has install issues or the controls are not set up correctly..HPs work really well in my part of the country (North TX)..
