Professional, knowledgeable, reliable. Excellent service.

At age 80 and having owned numerous homes and rental properties, I have had a lot of experience dealing with heating an AC service providers. Collier’s is one of the best. Jarod, head of installation services, and Trent, a very experienced installer, are both very professional, knowledgeable, and skilled at installing complex furnace and AC systems for the homeowner’s complete comfort. You won’t go wrong with Collier’s heating and air condoning.

Love my new tankless water heater!

The installers, Jeff and Skylar from Collier’s, are very professional and did a wonderful job putting in the new tankless water heater. Jeff took the time to explain this type of water heater to me. They were respectful of my floors; putting down tarps, and when finished with the installation they tidied up theIr working area so well. I was impressed and highly recommend Collier’s.
