I would like to give a shoutout to the whole team at Reliance Durham. On short notice and with some logistics to work out, these guys pulled it together and installed a new furnace, air conditioner, tankless water heater, water softener and reverse osmosis system all in one day!!!! Every one of them was professional and had a great attitude despite having to work in such close quarters… the teamwork was really great to see!!!

Jon was prompt and on-time. He was able to take one look at my toilet and knew the water line needed to be replaced. He had it replaced in seconds. Very friendly. He is one of the reasons I'm glad I have a plumbing protection plan with Reliance. Worth every penny.

Tanuja P

The workers were extremely nice. They were informative and finished the job quickly. They offered amazing advice and helped walk us through the entire process of running our AC/furnace. Thank you for all of your help!! We really appreciate it

Tracy C

We required repairs on our outdoor AC unit (likely due to its age) and were very happy about the quick response and service provided. The technician provided us with as much information as possible and allowed us to make an informed decision. The technician also followed strict safety measures due to COVID 19 which we very much appreciated.
