Then you don't really need a heat pump. Simplifies things.

I'd have sit down and see what the difference would be because it would be nice for the occasional cold day and as a back up heat source.

I talked to the dealer about the lower internet pricing. He says sometimes he can't get the same pricing as a large distributor, and that they wouldn't honor the extended warranty on a unit he didn't purchase himself directly from Mitsubishi. If it's installed by a "diamond" dealer, which he is, the warranty goes to 7 years parts, 7 years compressor. He's also throwing in 2 years free labor. He did agree to to knock approx. $500 off, so we decided to go forward with the deal.

Greenmachine, the heat pumps are probably more efficient than your current hot water system. The prices on the units that cool only aren't that different from the ones that also heat.

You would probably amortize that difference very quickly. There are also rebates out there from electric companies, tax credits from the Feds, etc.

Now we're keeping our fingers crossed and hoping we made the right decision.

I'll update as things happen, installation will probably begin in about 2 weeks.

I know a guy with older not sure what brand heat pumps and his house is bigger than mine but his experience is they work good down to about the 30s outside and then can't keep up. The thing for me is if i do the a/c units if the price difference is around $1000 or less then its a no brainer to just get them.

I hope yours works well and please let us know how everything went, the extra you're paying using the dealer could be made up in 1 warramty claim down the road.

Heating down to only 30 deg. is older technology. The new ones can heat down to -13F, and are still efficient down to 5degF. I'm in southern New England and very rarely go below 5deg F.

The electric baseboard setup will remain for emergencies, at least until the heat pumps prove themselves.

The newer ones work well in colder temperatures. I've used my Grunaire in temperatures down to zero without a problem.

Yep its older units he has probaly atleast 5 years old i'd think. I look forward to seeing how you like your units and if you'd do anything diffrent with them.

50% deposit has been sent to installer, electrician on board, installation in a week or 2.

I'm also having an insulation guy come in and give me an evaluation. They install a blower on the front door frame, and suck air out of the house and check for intrusion leaks. By doing this in conjunction with the heat pump installation, I get an additional $1000 rebate from my electric company. Probably not a bad idea anyway.

The power company here does the blower door testing. If they make recommendations be it more insulation , new windows or whatever , they pay part of it.

Same here. The insulation guy is a preferred installer by the electric company, and they share part of the costs of additional insulation.

I'm also going to see what the electrician will want to install an electric panel interlock for an outside generator feed as long as he's here.

All these discounts are starting to get pricy!

The owner and crew came yesterday and installed the Mitsubishi heat pumps. It's a 3 ton compressor and 3 wall units. They came en mass, 6 installers and 2 electricians. All wall unit electrics feed off the one line to the compressor, so only one line is required to the electric panel. The electricians also installed the lines to each wall unit. While they were here, I also had them install a generator interlock panel on the electrical panel and install 2 outside outlets. I saved some money on installation based on the fact that they were here already. They gave a very good price on the interlock installation, which included the new gen cord they made.

I could not have been happier with the level of workmanship of the installers. I had read up about installation, and they did everything by the book. No small time saving measures or cutting corners, it was exactly as Mitsubishi wanted. They were very careful in leveling everything, much measuring before anything was placed, inside or outside. I was also thrilled that they had sufficient workers present to complete the installation in one day. They had laid down tarps in my house to insure no dirt got on the floors, and cleaned up afterwards. When drilling holes, a dustpan was held under to catch any drywall dust. The electricians picked up every bit of scrap, including small bits of wire insulation and saw dust, inside and out.

There are some white plastic ducts on the outside of the house that the coolant lines, electrics, and water drains run in, not the most aesthetically pleasing, but I guess when I get used to them, I won't notice them as much. I have a white house so they sort of blend in, but they can also be painted. Only a 3" hole is required through the outside walls for each unit, and the units themselves are high wall mounted, which I think are better looking than window units.

They evacuated the system, and then held the pressure for several minutes to be sure all joints, seals, and connections were leak free.

Once the system was up and running, they stayed around to monitor it and be sure water extracted from the air was draining properly, and that the units were operating properly. They also spent time with us showing us the features and best use of the systems on the hand held remotes. Each inside unit can be operated totally separate from each other, and with different settings and temperatures. On the large unit in the living room, on one setting the vents can oscillate up and down to distribute the cooled air to different levels.

They were initially set on high to cool the house quickly, and we soon had to turn them down, it got to the point where you could have hung meat in there. We then set them for 77deg. which, without any moisture in the air, was very comfortable. The 2 bedroom units and the living room unit are definitely able to cool the whole 1550 sq. ft. house.

One thing I found of interest in talking to the electricians was that the entire unit runs off one 20 amp circuit, which says a lot about the efficiency, no giant current draw required.

I asked the company owner about any problems in general with Mitsibishi's circuit boards and compressors, and he said if installed properly they're trouble free, but installation was key. He also pointed out that since he was a "Diamond" level installer, I was looking at a 7 year warranty on all parts and compressor, and he personally gave a 2 year labor warranty. I knew this, and normally take everything a sales person says with a grain of salt, but I'm keeping my fingers crossed he's right.

At this (hot and wet) point, I'm very satisfied with the way the units are working, and feel it was money well spent. I'll have to wait a few months to give a report on their heating ability and efficiency.

That right there is why if someday i do this i'll spend the extra money and have it done right and more importantly have the longer warranty because i've heard the circuit boards and such can get pretty expensive.

I'm glad its doing a good job cooling down your place because mines just a little smaller at 1300sg-ft so a setup like yours should work just fine for my place, enjoy your new coolness.

Keep an eye on those exterior wall penetrations, just in case rain could leak in.

I am glad for your good experience with these units and installers; that is the way people should work everywhere !!!

I, too, was concerned about the holes. He assured me, then followed up by doing it, that all holes would be foamed in to prevent any air, water, or "critter" intrusion.

His point was that each unit "reads" the ambient temperature, and adjusts accordingly. If there is outside air intrusion, it will throw off the units ability to correctly set itself, so they are very careful to seal it off.

One thing I forgot to mention, and I consider this very important: the units are amazingly quiet. They are nothing like the average window unit, or even a central air system, which I find extremely loud. They are whisper quiet, on low setting you almost can't hear them. Same for the outside compressor, you can't hear it at all from 10' away. But run your hand behind the fan exhaust, and you feel the enormous amount of heat being pulled out.
