Sheer Comfort is our go to from now on. We have 5 rentals and 2 residences that we have service contracts on. We just had a 10yo heat pump, and a gas furnace/AC system replaced, also added a/c to a third existing gas furnace. All went without a hitch, and will save our renters money, and us headaches in the future. With the new refrigerant now required they explained repairing an older system would not be cost effective. Frank offered fair pricing options, and Lisa kept track of install dates and permitting. Ray and Tim did all installs, were neat and professional and prompt. They recommended an electrician also which saved us another hassle too. Have them give you a quote, you will be glad you did.
