Eli was great! He was by far more thorough than any technician has been! He explained everything he did and answered all if our questions. And he pet our beagle before he left!
I called and 52min later and very polite, knowledgeable, reassuring young man showed up and fixed my leaking toilet in under a minute tbh. He even offered to take off his boots without me having to ask. I thought that alone was very classy. So thank you very much for being there quickly in my time of need. I'll DEFINITELY trust any other issues I hopefully don't have to you fine people.

I wanted to post a review for DELCOR and especially my tech Victor. DELCOR has a preventative maintenance program that saves you from possible no heat or air by looking g at your units twice a year and fixing things ahead of time before you need it. Victoria found and fixed an issue with my heat that would have caused me to not have any of if I waited till I needed it. Now it will work when I need it.

I have used Delcor for years for my plumbing and AC issues and have always been very happy with their service and price. I did have some issues with my AC repairs in August but they came through and fixed all my issues, it took a little longer than I expected but all in all they did a GREAT job, I understand that shipping issue for parts can happen and it wasn't their fault for some of the delays. I will always use them and recommend them!
