Randy is the best. I am a happy and REPEAT customer…read more I had a small non-emergent issue late at night and he had someone out to me next morning. Then, after performing his work, he noticed a plumbing issue. Trent wouldn't leave until he had called and secured a plumber to come check out our problem on the same day. That is above and beyond service. If you are in North Houston and have A/C issues, then I highly recommend Certain Air.

Randy and his team did a fantastic job responding to our call, diagnosing the problem, and offering…read moreoptions. Our previous HVAC service who was recently purchased by John More wanted $4000 to replace a bad blower. Randy took a look at it and offered to fix it for a 1/3 of the other company's suggested price. He went further and suggested for a little bit more we could replace the furnace and receive a 10 year warranty. SOLD.. We will be using Certain Air going forward and highly recommend.

I know I just gave a 3 less than a month ago. But I have to say, aside from that one woman in the…read moreoffice, they really do deserve top notch ratings. Every service tech/installer/etc. that has come out has been beyond polite. They have apologized for the less than stellar CS I've received on the phone, and actually written down feedback from me regarding it. I recently had my entire system replaced. The whole process was so smooth. Wes was great at communicating the quote to me and answering all my questions. Jason came out to do measurements and discuss an additional vent in my main bedroom, and came up with the perfect plan. And the guys installing (Juan and Tony- I think I got that right) we're super polite and worked their butts off on the hottest day of the week with no complaints. They did a great job of being tidy too. My home, particularly my main bedroom, is cooling better than it has since the day I moved in. And honestly I couldn't be more pleased. Suppose I'll just have to hope for the nicer of the office gals when I call in for my twice a year check up.

My 85 yr old parents purchased an annual maintenance agreement from Hal Watson to have their A/C…read moresystem inspected twice/year. HW came, did something to their AC and said they needed a new condenser fan motor. $700.00. As soon as he left, their AC stopped working. Worked fine all year... the exact moment he left it no longer functioned. The odds are astronomical that the system suddenly broke the moment he left. HW maintains it was a coincidence and the motor was already failing. 100+ degrees and elderly people. $700. We called a relative who got the same part for $165 and put it in. We asked for a written inspection report and HW said "we don't do that". You decide for yourself if you want these guys in your home.

Personally, I felt like I was treated like the technician's PERSONAL ATM CARD.

They had to cut the driveway in three places and move hundreds of yards of dirt (see photos). Their crew was here every morning first thing, worked in the hot sun all day and cleaned up every afternoon before they left.

The price was competitive and the communication was excellent. They have my business for life!

My latest experience with Wallin Plumbing was when Trey and Jordan came out to solve a water leak, a clogged drain, and an outside patio faucet that needed replaced. These two gentlemen could not have been nicer, more efficient, and dealt with me more honestly. I see Wallin trucks in my subdivision constantly and there's a reason, reasonable pricing, quick response, and experienced people who know what they're doing. Wish I could rate more than 5 stars but that's the limit on this site.

They told me it did not need the extra…read morehalf ton, but did not explain that it would cause the problems it has caused ( high humidity, insufficient sized ducting, short cycling of the heater in cold weather, etc. etc. etc.). Now, I have a system that will wear out prematurely and does a terrible job at maintaining a comfortable home. When I asked them to give me a reasonable accomodation on pricing for a replacement system they did not bother to do that, but they did offer to sell me a whole home dehumidifier to reduce the high humidity levels in my house caused by the wrong sized system they installed. I was a senior senior citizen when they sold me the oversized system. I am told that the AG's office in Austin would be very interested, but I do not want to cause them that kind of problem. So. I am just stuck it seems. Be careful. They will sell you what you ask for whether it is technically correct for your home or not. Service requested: They gave me what I asked for. Quality: I got the Amana brand. Value: Wrong system for my home. Where's the value in that ?
