What customers say
"Recently had casteel come out to fix an AC issue not cooling. They are Way Overpriced and I feel like not very honest. The first thing the tech told me was that first off you need a thermostat and its not covered under warranty. Reason stated it was not sending low voltage to outside unit. The price quoted for just the thermostat was 512, for a $150 part. Which means to install the faceplate, 2-3 wires to connect, …"
— Kevin Holcombe · Mar 1, 2026 · Google Reviews"From start to finish, our experience with Casteel was excellent. I don't usually write reviews, but I felt this experience deserved to be shared. Our HVAC system was still working, but we knew replacement was likely the best long-term decision. Cory took the time to explain all of our options without pressure, and his knowledge and professionalism made us feel confident moving forward. The installation team(Nick,Moh…"
— Cindy O · May 27, 2026 · Google Reviews"We replaced one of our HVAC units in 2024. A few days before listing our home, our AC stopped cooling.

He reassured me the issue was likely something simple. After diagnosing the problem, he explained everything to me and had our system runnin…"

Jamie, the technician, was super friendly and knowledgeable. He replaced the water heater th…"
— John Shereikis · Jan 21, 2026 · Google Reviews"Chuck came out and correctly diagnosed the issue with our old system. It needed to be replaced. Clint came out the same day and discussed the various options. We went with the higher end Daikin system. It wasn't cheap but we believe it will provide the best service and value. Yesterday, Levi, Chase, and David came at 7am to get started on the install. It was an all day job and they took great care to keep our home …"
