About Our Technicians


"We recently had an issue with out AC, and after a quick call to Darrell's (I called before business hours, expecting to leave a message, but he answered!) I was walked through a quick bit of troubleshooting (checking breakers) and such and was then told that a tech could arrive the following day. I then got a call back a couple of hours later and was told that they were able to shuffle things around to fit us in...on a Sunday!!  The tech arrived, was super qualified and nice as heck, and sussed out the issue right away. He did need to return the following day with the required part, but he called first thing, arrived right on time, and got us nice and cool again. They have a customer for life! You could surely call someone else for your AC needs...but you'd be making a mistake."
