Reviews of local pros in Keller, Texas

Service One was assigned to my gas furnace service request through American Home Shield. They scheduled my service technician the next morning. Kenny arrived on time and was courteous, respectful and knowledgeable.

I have used Service One Air multiple times. They are very honest and meticulous in identifying the root cause and fixing issues. Appreciate Josh from Service One as well.

I had a fantastic experience with Service One Air. From the very beginning, their customer service stood out.

Key Highlights
Prompt Response: I called on a Sunday, and they answered the phone right away. It was impressive to get such quick assistance, especially on a weekend.

Easy Scheduling: They were able to set up my appointment for the very next day (Monday), which made the whole process smooth and convenient.

Professional Staff: The technician who came out was extremely knowledgeable and took the time to explain everything clearly.

Friendly Service: She was also very friendly, making me feel comfortable and confident in the service I was receiving.

Recommendation
I highly recommend Service One Air for their prompt, professional, and personable service. They made the entire process stress-free, from the initial phone call to the completion of the service.

This company does very shady business practices. A tech from this company came which was contracted by AHS. He came to do a furnace tune up. He did all the tests and said everything looks good. He then takes some pictures of my unit. Then he asks me a question that if I care about the safety of my family and I am like yes, what do you mean. He shows me a picture on his phone of some coils and tells me there is rust on it and that can cause carbon monoxide. I had another vendor a plumber come in, so I got busy with him. Furnace guy goes to a room and conducts a ppm test and after 10 mins he shows me 3 different photos taken at 2 mins with 4 ppm, 6 mins with 8 ppm and 10 mins with 11 ppm and says you're inhaling a lot of carbon monoxide which gets me worried. He then quotes me a $6k furnace replacement. I politely deny the service and told him that I will think about it and he goes on his way.
I call another company to get a second opinion and the tech tells the only way you have carbon monoxide is when you have cracked coils or there's a leak and by law if the guys sees any ppm levels more than 0, they then need to shut off the gas connection or they lose license.
He then tells me that you have to take the motor off to see the coils, at which point I tell him he didn't take apart any motor and just showed me photos on his phone of both the coils and the ppm readings. This guy does all his tests and says he found no issues and says possibly the other tech was trying to scam you to buy something which you really never needed to.
Please beware of this company!

Flawless encounter. Set up appointment at 11:15. Service complete at 1:35. Had the needed part on the truck. Trevor (tech) kept us informed about arrival time. Diagnosed and repaired quickly.

Kenny M. with Service One was great! Very professional and polite. Knew what to do and had our heat back and running in no time! (Taken care of by AHS warranty)

Josh provided great and detailed service on my two AC units. The tune up was informative and I'm glad we found some things to fix up before the spring and summer heat come in. Feeling confident!

Josh did a great job explaining everything to me and showing me how to change my filter. Very personable. patient, and professional! I bought the maintenance package, too!!

Service1 was top notch. We hired them to service two A/C units when we bought our new house in May 2025. They worked well with our home warranty company. Then we hired them to install a new condenser on the downstairs A/C. They were able to figure out why our master bedroom was unusually hot (a problem no one had pinpointed in the 20+ year lifespan of the home). We continued to be impressed, so we also hired them to run a new line from the A/C to one of the rooms. And finally they blew some new insulation in the attic for us. We feel that we got a very good value for the money we spent. We will continue using this company.

Josh was efficient and effective in servicing our unit. Also, he was cordial and thorough in explaining each step in the process.Lastly, he was extremely patient in tolerating our two rambunctious dogs. A wonderful experience all around.

Josh came out and looked at my HVAC system and was very quick and honest. Showed me all my options and the pricing was fair. Would highly recommend

Had a great experience with Spencer today! He came out to service my a/c unit to get it ready for the winter. This is part of a plan I purchased. He cleaned and checked everything thoroughly. Spencer is polite, professional, and is a wonderful representative of Service One.

Josh arrived on time, and he was very professional, courteous, and knowledgeable. He diagnosed the issue, explained the steps forward, and made sure I understood the literal fine print where I signed. Thanks!

Trevor and Tanner came to fix my HVAC and were extremely knowledgeable, kind and quick. They made sure the issue was resolved and did an amazing job. I highly recommend them and their service!

Service One came out and serviced one of our units that wasn’t getting any power to the thermostat. Kenny, our technician was very thorough and knowledgeable. He also wore the booties inside our home (my Wife loved that)😂. Kenny was also very professional, performed a timely diagnosis on our unit and fixed the issue right away. Luckily it was only a blown fuse but he did a great job getting to the root cause of the problem. Thanks again!!!

I called this company and left a message on a Sunday morning as I woke up to smoke in my house. They called me back within an hour and we’re out to my house within a few hours. I ended up getting a call the very next morning which was a holiday they had found my part, went and picked it up and we’re back at my house that afternoon to repair my heat. I’m very thankful as I had parrots with babies and it had been 20° outside and i with no heat! Thank you so much Spencer…I would highly recommend him and this company. This would be my fourth appointment over a 6 month period.

Kenny was fantastic throughout the entire process. He took the time to explain everything clearly and made sure I understood each step. His professionalism really stood out — he was knowledgeable, patient, and respectful. It’s rare to find someone who combines expertise with such great communication skills. Highly recommend working with him!

John was our tech for our spring AC check. He was great! He was very thorough and friendly - not pushy. We will definitely call Service One again

Spencer was great! Finished the job really fast. He was very courteous and explained what was going on in a way I could understand! Highly recommend! Great overall experience!

Fantastic service. They came on very short notice, diagnosed my HVAC issue and even came back the next day on Sunday with a part to make sure that we were nice and warm on a cold day. Kenny was super professional explained everything with patience and managed our
expectations very well. Would definitely recommend service one in the future for anybody in our area.
