Larson Air - Air Conditioning and Heating Service recently came out to check on a problem I was having with my gas furnace. I would turn the heat on, and it would take it five or ten minutes to start running. When Travis came out to check on it he showed the problem to me and it looked so serious I decided to replace the unit. It only took a day to remove the old one and get the new one installed. It was great to have it working again on the same day. I highly recommend them and would definitely use them again.
