Dustin and Chris came to install my new boiler and indirect water heater. They did an amazing job. They were very professional, friendly and answered all my questions. I trusted them completely. They also left the worksite spotless. I'm very happy with the service they provided and would recommend them.

I had our A/C and furnace installed by Dustin and Chris from Reliance Holmes yesterday. Starting with Sandro, the home comfort advisor who provided the quotation, they did an excellent job - very professional and courteous throughout. Dustin clearly explained the whole procedure to me and provided all the information I needed. Keep up the good work!

Hi, I’m Sandro. I started my career in HVAC, after being away for work in a different city and getting the call from my wife, in the middle of the night to deliver the news that our furnace stopped working, when was -30 outside. What started with a stressful experience, helped me pivot my career, with the mission to help my customer avoid similar fate. If you have any questions or concerns about your home comfort needs, do not hesitate in contacting me. Cheerfully, Sandro
