John is one of the most professional Service Techs I've ever had. He was knowledgeable, sharp, and helpful. He came for regular maintenance check-up, and when discovering a problem (closed coil fins) we've had for a few years, never dealt with by previous Techs from more than one firm, John explained how he could repair
the problem for a reasonable price. The result is we'll have much quicker cooling,
and a longer lasting cooling system because he was willing to do some tedious work
that took an hour or more, rather than saying nothing could be done. We're very grateful to John Tervol.
