The sales person, John explained various options while listening to our needs. The technicians did a great job removing our old system and installing the new one. They explained how to change the filter as well as how to program the new thermostat. Everything was cleaned well when they were finished.

Jamar was very professional and showed us a video of the leak that was occurring in our unit. We didn't just have to take his word for it. He was very respectful and honest and I appreciated his great service.

A friendly and helpful Hiller representative came out to the house today to provide a quote for installation of a Kohler whole home generator. The representative Roy Hastings was very friendly and helpful, answering all my questions, and thoroughly explaining the process and associated fees. Overall, a pleasant experience, I plan using Hiller for the generator installation, as well as reaching back out to them for some of my other upcoming home projects!

Michael was very professional and you can tell he enjoys his job. He is definitely an asset to Hiller Heating and Cooling. He explained the plan for the job and actually got finished 2 days early. He is a young man with an excellent work ethic. Hiller should very proud of this crew. I would want them back. Finally, Michael is a natural leader. Hope these guys get a bonus for this job.

This was our first time using Hiller services for a shower concern that we had. Brian came out and he was quick and explained everything. We will definitely use them again for any future services related to the plumbing. Thank you!
