Your workman...in this case ..."Phil"...knows what he is doing...friendly service and attitude is always appreciated...I am not qualified to compare prices at this time but have been dealing with Air Conditioning Engineers for many years and never felt that the charges were exorbitant, but these days everything seems to have increased in price over what those same things used to cost...which of course is a reality considering how much competition is out there for our business, plus modern day production costs.
