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.

Faisal R

I was very happy with Chad's service on water heater. He acted promlly, efficiently and was vigilant on his surroundings during Covid-19. I would highly recommend him and he truly cares for what he is doing. Thank you for fixing the issue especially during these times.

Gizele M

Mitch Roberts was very professional. He explained the issue, answered all my questions and was able to resolved the problem. He was very friendly. Excellent communication skills. Highly recommend Mitch for all your plumbing needs

Ouida S

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.

Lesa S

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!!!
