When I was getting my cooling system installed I heard from a friend that Lin-Air was good at what they did. I called them over to get an estimate and it was a great one at that. When they got to work, which was during the summer may I add, they worked carefully and fast getting the job in what seemed like no time. The workers were very professional and did an excellent job. I must say that I was impressed by their work and am glad I contracted them to fix my old energy sucking air conditioning system. Thanks to them my summers are not as hot as previous years. Lin-Air is the real deal.
