A selection of 700+ homeowner reviews:
“I was extremely happy with One Hour Air Conditioning & Heating from the first appointment to the repair. What should have been a frustrating experience with a broken A/C turned out to be positive because of the great customer service from everyone at the company. I would highly recommend them.”
“This is the first time anyone serviced my air conditioner totally and completely. They took the unit apart and cleaned the coils, checked the Freon, and ensured every part was in good working order. I would give high marks to the technician, who was patient, kind, and trustworthy?—A+.”
“Excellent service. The service agent was respectful and honest. He took time to explain the process to me.”
“I've been using them since 2003. They do great work and are always helpful—A+.”
“Always on time, efficient, caring for house and surroundings. Good recommendations and reviews of work done. Good technicians-keepers.”
“They are on time and do quality work. Technicians are very knowledgeable. We have used them for years.”
“We have used One Hour for the last several years. However, we ask for Frankie to perform the inspection/work and we are willing to adjust schedule to meet Frankie's availability.”
“Tech arrived ahead of schedule and had a trainee with him. Both were very up to date and provided information I didn't know about. They were thorough with spring tune-up and had made some good suggestions.”
“I have used this company for over 20 years and have always had a positive experience with them.”
“Excellent. I will call them again.”
“Our favorite A/C/Heating service provider - do a good job.”
“Beginning w/ AMANDA, in the office who did the scheduling of appointments to the Jr. Tech, Melbin; Sr. Tech, Alfonso; Comfort Specialist, Larry Thurman (awesome); and the guys who installed the new A/C unit, Henry & Fabio, all were prompt, thorough & clear w/ explanations, and clean w/ their work.”
“We have been using One Hour for about 15 years, in which time they installed air conditioning and heating units in 2 houses and provided the yearly maintenance. In that time we have found the company to be reliable, and in the few instances we had a problem, we found One Hour to be willing to resolve the issue, and ensure we were satisfied with the service. To us, that is as good as it gets!”
“The company communicates well with customers re: appointments to set and reminders. Staff are knowledgeable, make prudent suggestions & answer questions. They complete work in a timely manner and give explanations if that cannot be done. The staff is very respectful & friendly.”
“My service tech named Dan was very informative. I feel very comfortable.”
“One Hour provided very prompt service to my home. They were the most willing to come out and assist my family when the A/C went out. Their fix was done in a professional and timely manner. However there were a few bumps along the way, One Hour needed to come back two additional times to properly ensure the drain line from my new A/C unit were working because they were installed incorrectly at first. All in all my wife and I are happy with them as service professionals, and would use them again.”
“He did well, but a little heavy on the sales of new items—he just wouldn't quit trying to sell.”
“As members of the 'elderly generation' we can no longer perform maintenance on our A/C and Heating unit. We have complete confidence in the technicians at One Hour to take care of this for us.”
“Good techs, good quality work.”
“The technician was very efficient and helpful.”
“Manuel recently performed the work at my home. I appreciated his transparency, his expediency, quality work, and I would definitely request his presence again. Thank you One-Hour for maintaining such quality follow-up standards.”
“One Hour comes out once every six months to service our A/C/Heating Equipment, we have always had a positive experience.”
“Dan Harrison is the best.”
“The technician that came to my house had a One Hour Air/Heat truck. He introduced himself. He was very courteous and polite. I will definitely use them again.”
“They have installed two A/C and Heating units in my house and I was very pleased with the workmanship. I appreciated their overall professionalism and I recommend this company.”
“All options were explained clearly. Crew was well trained, diligent and personable. They held to their cost estimate and even corrected some problems left over from the builder years earlier.”
“The technician on the job seemed to be competent and knowledgeable. He completed his work timely and left no mess for me to clean up.”
“We have had great experiences with One Hour - they are reliable and our air condition and heater service has been doing fine since we have been using their service.”
“Manuel and Willie were great. They both were very friendly and knowledgeable.”
“I like having the monthly plan with One Hour A/C and Heating because I've had a couple of situations where I've been out of A/C or Heat, and when I call One Hour A/C and Heating they are always there for me A.S.A.P. (the same day) and are so professional! These are the types of people I like to work with. It is so worth it paying a monthly fee every month for A/C and Heating. Thank you!”
“I've used One Hour Air Conditioning & Heating, and they've been good. They come when they say will and do maintenance. It's been satisfactory. I've used them for years. They're excellent with no complaints. They get an A.”
“They checked out a condenser problem on the A/C unit. They had excellent customer service, they were on time, and they showed up when they guaranteed they would—all good points. I'd give them an A.”
“We got an air conditioner from them, and they were fine. I had to call them out because of a problem that we had. As far as customer service goes, I love them. For the work, I'd give them an A.”
“They replaced a component in the A/C unit. It was quick and simple. The guys were professional, and it was good. They're excellent.”
“One Hour was able to fix the problem that day and in a timely manner. They got the system working again. They added something to make it not stop again if whatever was wrong went out again. I'd give them an A.”
“They were perfect across the board. I'd give them an A.”
“I've been using One Hour for probably 17 years. We use the same service guy every time. They do repair work, and then they do the annual checkup. I think we had an A/C issue in our old house, and they came out when they were a different name. I'd give them an A+.”
“They did a thorough job, and I liked the representative that was there at the house. They did maintenance, and then they did a whole new air conditioning unit. Their customer service was good probably because of their representatives. I'd give One Hour an A+.”
“We used them for, like, 18 years. I used them when they were a different name. I liked their promptness and the friendliness of the technician. They were always there when they said they'd be. With our air conditioners, they always came promptly—in the middle of the summer in Houston when it's 100 degrees, you need your air conditioner. They were always really good to get out there the day it broke or the next day. They do the service for me. The people we bought our house from had used One Hour and gave us their number, and we just continued to use them. They're A+.”
“They installed a new A/C and heating system on our third floor. They did a great job—they were clean, and efficient, and they worked well. The inspector came out and said it was exemplary. We've been using them for years at our other house. I'd say they're an A+.”
“They were supposed to come today, but the rain prohibits them from doing any work, so they'll be coming on Monday. Everything is quite in order. They seem to always let you know when they're coming. They come here and officially do it, and everything works. What more can you ask? They check how things are working because we have a rather small space for our machinery, and sometimes it mildews and doesn't work well. I would give them an A.”
“They've been over several times. They come on time, and the guys are clean and courteous. They follow through on what they say they're going to do, so I'm real happy with them. They service my heating and air conditioning. They do service and replace equipment and put in other features and stuff. I used to use them a long time ago. I moved back to Houston, looked them up, and found out that they were now One Hour, so I went back to them again. I'd give them an A.”
“They looked at my air conditioning for an inspection. They were there early. I'd give them an A.”
“I think One Hour came out to do a tune-up. They come twice a year—once before summertime and then again before wintertime hits. They're polite and really detailed when they're explaining stuff to you. They get an A.”
“It's nice, and I'm happy with it. It was an emergency, and he called on time and fixed it. He was very nice and very professional, so I'm happy with him. I picked them because they could respond in 24 hours. I'll give them an A.”
“It was great. I think it was Memorial Day weekend when they came, so that was important. I'd give them an A.”
“One Hour did a great job. They completely replaced my air conditioner and furnace. They were on time and neat. I would give them an A.”
“They repaired the air conditioner, and from what I recall, it was a good experience. They explained what they were going to do, and they completed it in the time that they estimated it would take them to complete the job. I'd give them an A.”
“We called them for general maintenance, and they were there on time for what we needed. That's not the first time we called on them, so that's why I think they're reliable to do what we needed. We've used them several times. It's an A for One Hour.”
“They were very good and very professional, and they did a good job. I've been using them for a long time. They're an A.”
