MHC was able to source the air conditioner very quicly. They showed up on time and installed it in about an hour and a half. There were no extra costs and the unit was worked very well since having it installed about 5 months ago. The only thing I would recommend, is to have an electrician verify the wiring afterwards. They had used a circuit breaker that was of a higher rating than the specifications required, so I had to have a new circuit breaker installed. The rest of the installation was good.
