"The 14 year old self contained AC unit on our park model trailer died. I called John Mavic and he came out the next morning and figured out that the compressor in the unit was fried. We agreed that the age of the unit would make it better and faster to just replace the whole thing. He ordered a new unit and two weeks later it arrived at his shop and he came out and installed it the next morning. The work was done quickly and very competently. I have no complaints about the workmanship or the time it took to get the new one. I’m another happy customer."
