Reviews of local pros in Lee's Summit, Missouri

Carlo and Cody did an awesome job replacing our HVAC system. From start to finish, they were professional, efficient, and made sure everything was done right. The installation went smoothly, they kept everything clean, and took the time to explain the system and answer any questions. They even loved on our dog, who was very interested in their work and supervised their every move…ha!

It’s such a relief knowing we’re in good hands—thank you both for the great work!

Great service and very knowledgeable techs. Would definitely recommend this company.

Amazing work, and they dont feed you bs! They dont try to sell you stuff you dont need and they will go out of their way to fix your issues.

Zach's experience really paid off. He knew exactly what was wrong and fixed the problem right away.

This was the worst company I’ve ever had the misfortune of working with. While they were available to come out quickly for help during cold weather to fix my furnace-they took FIVE different visits over three days to actually fix the issue and my home was without heat the majority of that time. They blew breakers in my home while here that they said were not their fault and they would not repair that effectively left all of the bedrooms in my house without power and a small electrical fire in the kitchen. So now I will have to tack on an electrician repair because they are unable and unwilling to fix their mistakes. I will never recommend this company to others and hope to never be in a situation where they are the only option. I’ve added photos of one of the surge protectors they blew of two. It’s a miracle they didn’t burn our house down with their ignorance.

Addendum: We had an electrician out who showed us where a junction box in our home was recently damaged and stated that he believed the two staff from One Hour (Chase and Josh) had blown our breaker and the next day had run double the voltage through our junction box which caused the surge protectors to catch fire in my home. These two staff with One Hour never be revisiting our home in the future for service. This information was also relayed to management with One Hour.

One Hour refunded our cost after this review was posted.

Matt from one hour saved me when he saw I had a flat! I will definitely always be a customer! Thanks one hour!

Brett came in, very professional, immediately found the issue, explained and answered all our questions. Repaired it quickly and checked thoroughly that everything was working correctly. Would highly recommend.

When One Hour sent Ethan Claxton out to our house for a new furnace swap they sent the best in the business in my opinion. Quality workmanship and friendly as they come! 5 stars only because 6 stars wasn’t an option!

My installation is going on as we speak. I’m not even going to wait until it’s all done for the review. I have full confidence based on the professionalism I have seen so far that all will be well. The salesman that came out was knowledgeable, courteous and respectful. Not pushy at all. It went a long way in our decision to go with OneHour.
The technicians that are here today are hard working and professional. I would hire this company again in a hot minute. The whole process has been made very easy for us and that is appreciated.

Josh was absolutely excellent. He is knowledgeable and very professional. He explained everything he did... As well as guidance to what I could do to keep the unit running well. We are very grateful for Josh.

I had an issue that had me second guessing my future business with One Hour i am No longer second guessing. The way the management staff responded and took care of it had me beyond grateful. Ryan came out on several occasions and his customer service and thoroughness was exceptional. I didn’t expect this level of service and am blown away at how my issue was resolved.
Thank you for your customer service and your care.

Fantastic. We are very happy with the heating and cooling system we bought from One Hour Heating and Cooling. We bought a 96% heater, 18.4 Seer 2 a/c, humidifier, and air purifier. Our old system was over 20 years old and had some very funny duct work for the heater and One hour heating and cooling replaced all of it up to code as part of the insulation. Another company we had an estimate from wanted to charge us an additional $800 dollars to bring it up to code. Bret was who came for the estimate, and Ethan and his team is who installed the system. Everyone was very respectful, friendly, knowledgeable, and answer any and all questions we had. We appreciated that One Hour heating and Cooling price matched to help us get the best system for our budget. I also like the perks that are included with the service club. My sister enjoyed that she was given a bonus for referring us to One hour Heating and Cooling. My sister bought her system over 5 years ago, has the service plan is has also been very happy with all of her interactions with One Hour Heating and Cooling, as well as her system. I highly recommend One Hour Heating and Cooling.

When my 20+ year-old furnace went out on one of the coldest week-end nights in February, I needed someone who’d not only get here FAST, but also, be knowledgeable, reasonably priced, and courteous—aka, AWESOME! Frankly, I was holding my breath, but I lucked out with One Hour Heating & Air Conditioning. Bret, the Service Advisor, came initially, got it running, but it needed more parts. He laid out all my future options to fully repair or replace, pros and cons, no rushing or pushing. (I’ve worked in sales, and I couldn’t have done a better job myself. Full kudos to Bret!) Having gone through multiple years of worrying whether my furnace would make it through the winter, I decided I’d finally get a new one. GREAT DECISION! Ethan and his crew were here in two days with space heaters to keep me warm while they installed my new furnace quickly, quietly, and efficiently, putting down tarps and being mindful of my flooring when going in and out. They truly went out of their way with their customer service! My new, high-SEER furnace is cheaper to operate, quieter, smaller, and providing more even, comfortable heating with dual-floor thermostat operation. Best of all, with 1-Hour’s top-notch response and future service availability (which I doubt I’ll even need!), and great guarantees, NO MORE WORRIES ABOUT MY FURNACE GOING OUT! Thank you, Bret, Ethan and the Guys, and One Hour! It’s family-owned and -operated, and I could sure tell the difference.

Brett did a great job explaining everything to me! You can tell he really enjoys his job and loves what he does. He adjusted our gas pressure so it wouldn't burn too hot this winter and asked lots of great questions to make sure we were happy with how our system was running. Thank you so much for taking your time and answering all my questions!

4/1/25 Jack was very thorough in his work, and he even took the time to look up my warranty. I appreciated him answering all my questions as well.

Having had the pleasure of working with Bret multiple times, he is awesome and radiates calmness in my time of stress. Very punctual and professional, explaining the issue and how we could handle it. We had a complete installation, which was the best option. Cost acceptable for us. I highly recommend Bret and this company for your heating and cooling needs. Thank you to all

I almost never do reviews, but I have to with One Hour Heating & Cooling. My AC went out when we were in a heat advisory (of course) and they sent someone out within a couple of hours. Cory was professional, kind and personable. He fixed the problem within an hour and I couldn't be more grateful!!! Cory will be my HVAC person from now on! 😊

5 STARS!!! The tech you sent to my house was a great communicator and highly professional. He gave me multiple options on how to move forward. I appreciate that he was on time, careful to clean up after himself and answered all of my questions. That is why your company is the only one I use...end of story. I know I can trust your employees to give me the straight and honest truth. I appreciate that so very much.

Will and Jack performed the spring tuneup on our AC unit. Both of them were very courteous and professional. They did a very thorough job inspecting and testing everything. They did a great job cleaning the outside unit to make sure it will perform efficiently this summer. They made sure I had the opportunity to ask any questions before they left. We’ve had nothing but positive interactions with this company and the wonderful people that work there. Thank You!

Zach F. Was awesome. He checked everything out and luckily it was all good. Great guy would recommend to a friend.

Brendon and his crew arrived on time and quickly got to work. The installation went quick and they were very courteous. Everyone answered my many questions with helpful information. They cleaned up After they were done. Also, they put up with our dogs who always wanted to help. I highly recommend them. Thank you. This is the second review. They graciously came back and raised an exhaust vent so that we could have headroom. They would’ve done this when they were here originally, but we didn’t see it until they were almost done. I can only say that everyone that I have talked to with one hour has Been courteous and very helpful. I’m impressed with the way they take pride in their work. And it shows by the finish product I highly recommend them

Cory R was super knowledge. Put up with all my questions and gave me all the information we need to make an informed decision. Thank you.
