I bought a Mitsubishi high-efficiency heat pump online and had Bill install it at my vacation home in July 2014.  It worked fine that summer as an air conditioner, but in the Fall it failed to provide any heat at all.
I asked Bill to check the unit.  He said it had enough refrigerant, was working well, and showed no error codes. He told me I had purchased a heat pump that was not high efficiency--but in fact he misread the model number, and I had purchased the right unit.  I then spent a lot of time with engineers at the company I had bought the unit from and with engineers at Mitsubishi.  No solution.
I contacted Bill Lohsen repeatedly to ask him to check the unit again, but he did not respond to my emails.
I finally had another Mitsubishi dealer check the unit.  He told me that heat pumps that are not completely charged with refrigerant will still cool well but will not produce heat--that's why Bill told me the unit was "working well."  The new dealer found that the connections on the refrigerant lines had leaked and the unit was almost out of refrigerant.  He fixed the leaks and replaced the refrigerant, and it now seems to work fine.  I emailed Bill Lohsen and told him of these findings, but he continues to insist that his installation was not at fault, and that I am responsible for all the problems I have experienced.
I learned (too late) that Mitsubishi has two levels of dealers, and Bill is at the lower level.  Units installed by the higher (diamond) level get a longer warranty.  Bill cost me a full year of use of the unit as a heater by failing to realize that the unit had leaks and was low on refrigerant, by mis-reading the model number on the unit, and then by not responding to my requests for service.

Very prompt to my estimate request. From the time I requested the estimate to the day they installed my new boiler was only 2 weeks. The work was done quickly and efficiently. These guys know exactly what they are doing. I called their emergency number in January due to a lost prime on my oil system (Was my fault). They were at my door in 45 minutes and the problem was fixed in under 5 minutes. My go to plumbing and heating company.

I had done extensive research on the options available and saw lots of comments about contractors not knowing how to properly install , program and test these systems. Bill Loshen did a very neat, flawless installation, spent considerable time programming the unit, tested it, and cleaned up the site when they were done. They also removed all the old fixtures and debris. It has been eighteen months, and the only thing I have noticed about the system is that it is quieter, the water is hotter longer, the house is warmer faster, and my propane bills are lower. My research indicated that call backs are the norm, and there are usually glitches and corrections required. Not so in this case. The contractor knows what he is doing. Before he left, he asked us to evaluate the temperature and pressure at various points in the house, and he made adjustments until we were happy. If you're concerned about having a competent contractor install a sophisticated system, I recommend Bill Loshen Plumbing and Heating.
