Kirk came out for as a second opinion for some work that was supposed to be needed. I was told this by another company who regularly serviced our units. It seemed like they were always repairing something. I decided to get a 2nd opinion to make sure the repair/replacement was needed. Kirk showed up on time, checked my units and low and behold, no repairs or replacement of my smaller unit was needed!! Very honest about the status of our 20 yr old units and we decided to follow his suggestion- you don't need anything done!!!
