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.”
“We had them over to our house in October to repair the air conditioner. They seemed knowledgeable, and they thoroughly explained the options and choices that I had and how I could proceed with servicing my A/C. I chose them because they were able to get to me faster than anybody else that I tried. I'll give One Hour an A. I don't have any complaints.”
“It was great. The guys were really thorough and really good. I liked their prompt service and professionalism. I've got a couple of air conditioners that they installed about two or three years ago, and we started having issues with one of them. They came right out and did the service work that needed to be done—no problems, and no questions asked. Everything's still under warranty, but they jumped right on it with no hesitation. We had our whole central air and heating system replaced by One Hour, so I'm using them because the warranty and everything goes through them. I would say it's an A for them.”
“I had a good experience with them. They had quick service, and the quality seems to be there. Everything seems to be working properly. I'd give them an A.”
“I think the personnel were well informed and helpful in solving the problem that I had. It was a problem with the drain line for my air conditioner. I used their predecessor companies, so I've been working with them for some time. One Hour gets an A.”
“I've been with them for many, many years. They were a different company for a while, and I think One Hour bought them. The young man that came out to look at the air conditioning went way out of his way. He cleaned it up, and I know he did a little bit extra that he didn't need to do. He was very informative and told me a lot. I really appreciate the way he did the work on the air conditioning. There were lots of leaves around the air conditioning unit, and they raked that all away and got it out to the side. He cleaned out the air conditioning really well. He spent a lot of time, he was upstairs a lot, and he explained to me how everything works. It was a good experience. I'd give them an A.”
“It was fine. I've used them for years. One Hour gets an A.”
“I like how they tell you everything up front. They always come out right on time, and they're fast and friendly. We had our whole A/C and heating unit done in 2011. We had to replace everything, and they did all of that. One time there was a problem with one of the parts that went out, and they made it good. I like the tech that always helps us because he tells you everything—he explains what's going on. I'd give them an A.”
“One Hour replaced an air conditioner and heater, and they were all very professional. They were very good. I'd say they're an A.”
“They installed a new air conditioning system for me, and it's working fine. The two guys who came were very accommodating, friendly, and very professional. I called them because I saw that I needed to get somebody out. I'll give them an A because I have no complaints.”
“They just did a regular service check and found something on our system that had been opened up by the heater service and not sealed back up, so he sealed it back up. Everything's fine. It was good. The guy was fast, neat, and thorough, and I feel that he did a good job. I heard about them because they did some work at my office. They earned an A.”
“They inspected and repaired the A/C unit, and they seemed knowledgeable and efficient about that. It seemed to be easy to make an appointment. I'd grade them as an A.”
“I just had my equipment replaced by One Hour, and they did a good job. I think they are professional. I like them, so I'd give them an A.”
“They worked for us for about 40 years. They did the maintenance and the periodic checkups. They scheduled ahead of time, and they came on time and were efficient. I heard about them when they went by another name. One Hour is great. I'd give them an A.”
“One Hour fixed our air conditioning, and they did a great job. Everything was just fine. I found out about them from my son. They were on time and friendly, and everyone was very good. They deserve an A.”
“It was very good. They replaced the ducts in our house, I believe, and our A/C unit. They showed up within the appointment time, and they were very friendly and very professional. I'd give them an A.”
“I think they corrected our air conditioning when it was down. They got our air conditioning back to working condition. My husband chose them because the name was One Hour. They were very friendly, they worked very professionally, and they were good at it. I think we'd give them an A.”
“I remember the guy was nice, and he took care of it. I'd give them an A.”
“I'd give One Hour Air Conditioning & Heating an A.”
“They replaced my outdoor unit and the indoor coil, and they were able to do it quickly over the phone because I was out of town at the time. It was really easy to manage even when I wasn't here. They were very friendly and very professional. I'll give them an A.”
“I've had One Hour a couple of times. I had them check things a couple of times, and they fixed a leak. We've always liked them. I've recommended them to other people. I'd give them an A.”
“They did good work. I'd give them an A.”
“They fixed up my air conditioning and checked my furnace. They fixed me up. They accidently broke a lightbulb, but they fixed it—no problem. It's an A for them.”
“They actually came out twice. The first time, our A/C was broken, and they fixed it, so that was nice. I don't know exactly what they did, but they replaced the part and charged it back up with Freon. I know they said something they replaced was going to make our energy bill go down, and it actually did go down. The second time, they just came to do a semiannual inspection on our equipment or something like that. The guy was friendly, and he showed up on time and worked around our schedule. He recommended stuff that we could do in the future, but he didn't try to push it on us or anything like that, so that was nice. I guess I'd give them an A.”
“One Hour Air Conditioning & Heating was wonderful. The entire thing was very smooth—they fixed the heating, and it was unbelievable. They came to the rescue, so I really appreciated it. I'd give them an A+. I was so happy with the service.”
“We used One Hour, and they were exemplary in their work and wonderful with their follow-up. They are the ones that saved us. We had a phone call out to another company, and we waited, and they didn't come. One Hour came out within one hour and handled the whole thing. They get an A.”
“One Hour was excellent. The unit outside had a power connection to the house that kind of disintegrated or rotted through, and they put a new piece there. The guy was very professional and did a nice job. I would recommend them, and I would give them an A.”
“I have a contract with them. They install and do maintenance for me, and I think they're great. I've been using them for three years. Their technicians come out when I call them, and I have not had to call them back. I would highly recommend them to any neighbors who asked. I would rate One Hour as an A+ company.”
“I have been using them about five years. They've installed two all-house air purifiers, two new air conditioners, and one furnace. They've done a lot of work for me, and I have not had to call them back to fix anything. They are all highly trained, polite, and great. They're fast and efficient, and when they say they're going to be here at three o'clock, they are here at three o'clock. I can't say enough about how good the company is. I've recommended them to others, and I'd give them a triple A+.”
“Everything One Hour has done has left me satisfied. I would give them an A+ right down the line.”
“I had a good experience using One Hour. I have been using them for the last five years—maybe more—and they're excellent. They are prompt and knowledgeable, and I have not had to call them back. They should get an A because they're very good.”
“I have a service contract with them, and we replaced our air conditioning unit. They were reliable and took care of what we needed. The technicians come out when they are supposed to, and I haven't needed to call them back other than to do maintenance. I would recommend them, and I'd grade them as an A.”
“I bought my latest A/C unit from One Hour, and I have a contract with them. They were operating under a different name previously, and I used them then. I have always been happy with them, and I always ask for the same technician. I would recommend them highly, and I'd give them a straight A all across the board.”
“I've had a good experience with One Hour. They've done a good, A+ job.”
“I've been using them for three years. They installed a heat exchanger. Their service is good, and they show up when they say they're going to show up. I think they are very professional, and I'd give them a good recommendation. They get an A+ grade in my book.”
“I like everything about One Hour. I've been using them for a couple of years. We pay a monthly fee, and we call them out if anything happens. They are very sincere and honest. I would refer them if anybody I knew needed HVAC work. They're A+.”
“Daniel was great. I have been using them for about three years. They set up a program where they come out twice a year to check the air conditioner and the furnace to make sure the systems are working well before we start using them. So far, the preventative maintenance is working great; everything is working well. I'd recommend them, and I would say they deserve an A+.”
“They service our A/C and furnace twice a year, and they put in our furnace and our air conditioner. They do what they say they are going to do when they say they are going to do it. Every guy who has come in this house has been nice, neat, clean, well kept, and polite. They treat my home like a castle. They put the little shoe protectors on, even though I tell them they don't have to. The only problem we've had wasn't really a problem; it was a little bit of a mix-up. I had ordered some filters for the attic, and when they did the work, it was a different kind of filter. I went ahead and ordered two, but when they came the next time, they didn't have it. They actually went all over the place until they found one, so they made it all right. I'd absolutely recommend them, and I would definitely give them an A+. They have gone over and beyond. I love them.”
“I have been using One Hour for a couple of years, and I haven't had any problems with them. I feel like the people they send out know what they are doing. They come out twice a year to check the heater in the fall and the air in the spring. If anything needs to be done, they tell us, and we have a choice about whether we want to have it done or not. I like them. I would give them an A- rating.”
“They do a yearly checkup on my A/C. The technician was very informative. If I asked any questions, he gave me the answers. I have been using them for two years. I think I chose them when my A/C went out, and I saw their truck in the neighborhood. I am satisfied with their service. I would recommend them, and I'd rate them as an A+.”
“My system wasn't working well, and One Hour cleaned it up. They were on time, and the technician's customer service was fine. I heard about them because someone else in the neighborhood used them. I'd recommend them, and I would give them an A.”
“I've been using them for two years, and they've both installed and done maintenance for me. The technicians are OK. They show up on time. Several of my neighbors already use them, and I would continue to recommend them. I'd probably grade them as an A.”
“They're on time, they do good work, and they're clean. I've used them for at least a half dozen years—probably longer. I have had not had to call them back. I'd recommend them. They've earned an A.”
“We have been using One Hour for about two or three years now, and we like everything about them. They did a whole bunch of work for us. The technicians were all pretty good; they fulfilled their promises. They get an A from us.”
“I have been using them for a little over a year. They installed two new systems, and they set up the thermostat right when they installed the system. After that, it worked fine. They've been friendly, and they seem knowledgeable about what they're doing. I'd recommend them, and I'd give them an A.”
“One Hour checked out the air conditioner. They gave me a quick appointment, and they seemed honest. I did not have to call them back to fix anything, and I would say good things if anyone asked about them. I thought they were nice. I think they deserve an A grade.”
“I've used them for probably over thirty years. I have an annual contract for checkups, and they've put in the air conditioning, heat, and new furnaces. They've done quite a bit of work over the years. I would give them an A.”
“I have a service contract with them, and I got my new air conditioner from them. I've used them for about six years, and I like their dependability. The technicians show up when they are supposed to. I always tell my neighbors that they are who I use, so I would recommend them. They're an A-level company.”
“I have been using the company for five years. They seem to be knowledgeable, and they are dependable. Recently, the city inspector wanted a drainpipe changed that they had installed a few weeks before. They got someone here basically the next day to do a repair on it. I would very much recommend them. I would say they're worthy of an A rating.”
“I have been using them for three years. We have a service contract with them. We are renting our home, and they are our landlord's company. The technicians come out when they are supposed to, and they are very good, very efficient, and very quick. We haven't really had any problems; I would recommend them. I'd give them an A.”
“I've been using One Hour for about three years. I have a service contract with them, and they are great. They come out when they are supposed to. I heard about them through the company that put my air conditioning unit in my house. I would grade them as an A.”
