“Richie from One Hour Heating & Air Conditioning was awesome. He came out to check my system and did a really thorough job from start to finish. The technician was super friendly, explained everything in a way that made sense, and walked me through a few different options without being pushy at all.
I really appreciated how detailed the checkup was—it felt like they genuinely cared about making sure everything was working the way it should. You don’t always get that kind of attention and honesty these days.
All around, just a great experience. I’ll definitely be calling them again if I need anything in the future, and I wouldn’t hesitate to recommend them to anyone looking for HVAC help.”

“I’ve been with this company for 20 years. Chris exemplified the best of ONE HOUR! Super personable!! Highly informative! (the only negative thing I would like to say to the company is that I am and have been on a contract to have you come check my units every six months. This past time, it took eight months and it was only because I called to ask what was going on. I suspect this has happened on some of the other previous visits where more than six months time elapsed. I’ve never said anything about it. From here on out, I will be calling in and scheduling my own appointments. This was a bit disappointing I have to confess.).”

“First time using this part of the trio, (One hour heating and air, Benjamin Franklin plumbing, and Mr. Sparky electrical service), and I'm very pleased with the service we've received. All of the employees we've met and had conduct service on our house have been very pleasant, well mannered, respectful of our property, punctual, and knowledgeable in their craft. I am confident in my recommendation to anyone needing any of their services.”
