One Hour Heating & Air Conditioning of Sherman
serving Grayson and Collin County
Based in Sherman, we keep homes comfortable across Grayson and Collin County and down the US 75 corridor, from Denison and Pottsboro to Howe, Van Alstyne, Anna and Melissa, and the smaller towns in between, including Knollwood, Westminster and Weston.
The homes here vary a lot. In older houses around Sherman and Denison, the real problem is often tired ductwork or an aging system. In newer homes in Anna and Melissa, the first question is whether a builder warranty still covers the unit. We'll tell you which one you're dealing with before we quote anything.
Locally owned. Personally accountable. Nationally backed. Owner Scott Lunsford is a phone call away, and our technicians are licensed, background-checked and trained through the One Hour network. We answer 24/7, and we're Always On Time… Or You Don't Pay A Dime!®
Great team! Done job professionally in timely manner.
Super helpful and effective. Knew exactly how to get the gas fireplace up and running.
Adding to my positive comments regarding my recent One Hour furnace-installation experience: Odunayo Titunyemi and his team including Keelan Stewart and Thomas were spectacular! They worked carefully, efficently and steadily without so much as taking a break until the job was sucessfully completed. Their work ethic and professionalism exceeded my expectations. If you need a new furnace, I urge you to call One Hour; you are in good hands with Odu, Keelan and Thomas. My new furnace is working beautifully. Kyle and Jeff helped us to make an informed decision about furnace replacement. He was patient, supportive and guided us through the process in a trustworthy, reliable manner - working with his team to coordinate immediate plans to replace our furnace with a quality product (at a very reasonable, competitive price) in an extremely timely manner. I would recommend Kyle, Jeff and the One Hour family every time! That's why I have stayed with them for over 20 years.
This company installed two HVAC systems a while back in my home. My basement furnace would not start up, and a service call was set up. The service technician found that the induction motor was bound up and got it working but was loud. The part was ordered under warranty and was replaced with no labor charges based on some Cust. Sat. issues that I had. It was 8 plus years old. I appreciate the company working with me on that with no charge for the labor to T/S this and replace the part. Both techs. were very professional and did a good job.
Two guys (Tucker & Michael) came out to clean my Duct Boards. They did a great job and were very personable. I would recommend using One Hour for this service to anyone that needs it.
We have used One Hour Air Conditioning & Heating for over 10 years and they have been a great company. I recommend requesting Dane he has done a great job, he is curious, professional, and loves dogs. He has been to my house two times for our 6 months maintenance and he just returned for the 3rd time and performed a major part replacement (no error on their part. Issue was a wear and tear issue). They diagnosed and repaired a major component in less than 24 hours. The AC is working great and putting out cold air.
One Hour Heating and Air did an outstanding job servicing my heating and air conditioning equipment! From start to finish, the experience was excellent. The technician was professional, knowledgeable, and thorough, taking the time to make sure everything was running properly and efficiently. I really appreciate his attention to detail, quality of work, and commitment to customer satisfaction. It’s refreshing to work with a company that takes pride in what they do and puts its customers first. I highly recommend One Hour Air to anyone looking for reliable, professional HVAC services. I’ll definitely be using them again!
