"Angel was fantastic. He and his partner worked in the dark, until the project was complete. Amazing. The next morning I checked on the outstanding workmanship. Also, there was not a scrap of anything extra to be found. It was like the damage had never occurred. Highly recommend this company."

"We had Juan do some pretty extensive deck repair and replace a fluorescent light in our kitchen. Just before he was ready to work on the kitchen light, we changed our mind on what we wanted installed. Juan took all that in stride and we worked out the schedule. And the work on both the deck and the lights look GREAT. We have a couple of other projects in mind and are definitely calling Juan when we are ready to get them done."

"It was such a pleasure working with Brent. We had a difficult, unique project that we had previously asked several people to do, and nobody was able. He was very willing to come and evaluate the problem with our vent hood fan on a steep roof. He also was extremely communicative about each step. He also finished the repair way earlier than expected. I cannot recommend him more highly."

"I would suggest you drop all other services and go with this one only. This service man is far beyond the skills and service of all others. I had one show up in car and a back pack. He looked at and said he would send a quote ?????? My furnace is out , its late and the temp outside is 0. Tony Bertolini repaired it less then a hour with no parts. This is a man that knows his S!!! and is more than worth his charges.When the weather starts to warm up I will call him to install a new one . [ I will call no one else .}"

About us: "We have been in business for over 27 years and are Nastec and NATE certified. We do over 20,000 service calls per year and about 50% of those are from repeat and referral business. A couple of reasons for that are: we GET OUT the SAME DAY and we have our own training facility where our techs are kept up to date on all the industry changes and not necessarily on your equipment. We are master plumbers, master electricians, and an HVAC company so if you have any needs in these areas let us know."

"We thought pipes would need to be replaced due to leakage. Turned out to just need tightening of connections, something we had done but didn't last. Hopefully this goes care of problem."

"I signed up 3 years ago to the Swan Club, which includes yearly inspections of our furnace, ac, and plumbing. Mark recently inspected our air conditioning system. After purchasing an HVAC system from Swan, we joined the Swan Club, which includes yearly inspections. Yesterday our service technician was Mark. He was extremely thorough and professional, and and walked us through the whole system with pictures and comments. He could not have been more helpful. Thanks Mark"

"For my scheduled duct cleaning, Logan and Brandon arrived right on time. They were friendly, efficient, and went right to work. They did a great job, and when they left, I felt that my house was cleanest where nobody could see it, but my air is clean, too, and I appreciated the service. I give them five stars, and at least 12 points out of 10."

"One Hour has been my HVAC supplier for more than a decade, and I have never had a reason to consider any other firm. This week Justin L. and Steve came to install improvements. They were professional, courteous, and took the time to explain to me just what they were doing, and to answer my questions. On a scale of one to ten they were both elevens. I'd give them six stars if I could. You can trust One Hour to do it right."
