Since moving into my house seven months ago, I have used Crystal exclusively. They have been out about five times for maintenance and repairs, and I have yet to be disappointed. The most recent was a cold day when my furnace quit. Cary was there in a couple of hours, and got it up and running in no time. Unfortunately, another problem popped up later that same day, but he came right back and fixed it again. I don't plan on using anyone other than Crystal for my heating and cooling.

Darren arrived on time to check and service my furnace and heat pump. He was very professional as always when he has been here in the past. He went straight to work checking the control box, the furnace and the whole house humidifier making an adjustment to it. He then went out (in the cold) to inspect the heat pump and made an adjustment to it to quieten it down. He came back in to tell us the good news, see you in 6 months.

Service technicians are always prompt, thorough, efficient, and polite. Office personnel exhibit the same positive characteristics. We have been customers for many years and they have never disappointed us. Darren H. has always done our semiannual maintenance and installs; he has always been excellent. Today Joe K. thoroughly cleaned our ductwork, with an emphasis on”thorough.” As always, we are extremely pleased with the completion of his work.

Cary worked on my furnace today and was very professional and very friendly, he got right to work to try to determine what the problem was, his hands were really tied because he did not know which code to pursue. He cleaned what he thought was possibly the problem and checked other items making sure they were working properly. He told us if this did not solve the problem do not hesitate to call, He showed us how to determine what the code is if the problem should arise again. Thank you..........
