“Mario and Nick were very knowledgeable and worked really fast. The install looks very professional and works great! They did a great job and even walked us through the system to make sure we understood exactly what was done!”

“Kylie was at our home within an hour after we experienced an A/C emergency at 3:30 pm on a Friday afternoon. She was very attentive to our situation and why it was an emergency. I filled her in on what was going on with the A/C and she proceeded to get to work. She was able to fix the issue and preformed a complete condensation system check to prevent further problems. She took time to explain some preventative measures we could do to help prevent clogged pipes in the condensation system. She was very knowledgeable, professional, courteous, and helpful. Thank you again Kylie Bradley, we needed a small miracle that day and you turned out to be the miracle we needed. God bless you .”

“This man worked hard and was so thoughtful in all his work. He spent a lot of time, and I was impressed. He even changed my filter. I would recommend him & Benjamin Franklin heating and plumbing 💯 %. They have come every season for the past 10 yrs.”

“My mom’s AC went out on the hottest day of summer so far, and One Hour Heating & Cooling came through for us! As a KC customer, I knew I could count on the same great service when I saw One Hour pop up in my Google search. I really appreciated the same-day response. The tech, Robert Fitzgerald, quickly diagnosed the issue (thankfully an easy fix!) and there was absolutely no sales pressure—just honest service and a much cooler house. Highly recommend!”

“Great experience with this company! When they sent out a technician, they text his name, a photo of him, and a link to track his location by GPS. I called about an issue with my AC on Saturday, and they were able to get it fixed on Sunday. Michael Dorris was the person the company sent. He was so nice and knowledgeable. He walked me through all the steps he did and provided me with a lot of great information. Can't recommend him and the company enough.”

“Mitchell West was our technician. He arrived when he said that would be here. He immediately diagnosed the problem with our outside AC Unit, explained the problem and needed repairs to me. He also explained and showed me how to properly clean the outside unit which would help keep the unit running efficiently. Something that I will start doing every spring going forward. He was prompt, courteous, and very informative. It was a very good experience during the service call and even better when he was done as we had ice cold air flowing again in our house. Many thanks to Mitchell and AAA Northgate.”

“Ruben was very professional & knowledgeable. Very good guy to deal with. With my background I understood what he was talking about but he explained in a way that the normal home owner would understand. Your company is fortunate to have Ruben as an employee.”

“Sam Criss is a phenomenal asset to One Hour Olathe. He's polite, kind, smart, knows his stuff and able to get to the point with a smile. He listened to my concerns and not only addressed them all but came up with a game plan to avoid issues in the future. He addressed any confusion I had and looked me straight in the eyes when doing it. That level of professionalism is rare these days. Whatever they're paying him is certainly not enough. Customer for life!”

“I’m thoroughly impressed with One Hour Air’s process. Very efficient and super friendly. Tyler arrived at our home in the time frame promised. Communication was excellent throughout his visit. He answered all my questions and went out of his way to cool down our place while he worked on the main issue. His suggestions for improvements to our system were appreciated and welcomed. No hard sell involved, just a sensible addition which will improve the quality of the air we breathe. Thank you Tyler and thank you One Hour Air!”

“Our A/C stopped working. The tech Sam arrived when they said he would and he quickly diagnosed the problem. Courteous and knowledgeable. We needed a new system. The salesman Carter came out the next day and presented our options. Professional and detailed. The whole process was about as painless as a $18K decision could be. Their financing options make it all affordable. Highly recommend McCarthy's One Hour Heating & Air.”
