    Caden did a fantastic job. They were here within 20 minutes and diagnosed quickly and got us up and running. Didn’t feel pressure to do anything extra but made sure we were educated and had all of the facts to make a good decision.

    This is a long one but I think it is important for all you out there to know how amazing this company is. I have been meaning to make this review for quite some time. Unfortunately however, up until today I have neglected to do that. This was mainly due to the fact that distractions happen throughout my life and sometimes I forget to do things that I absolutely should have done weeks ago. Mind you, this is also being written after my first maintenance visit since getting my new air conditioning system put in. My air conditioning completely crapped out sometime in July I believe when it was around 900,000,000,000° out. This was perhaps the third time that it had glitched, and therefore the third time that I had to make a maintenance call for it. Prior to this day I had simply had someone come by to a replace a part here in there. It needs to be said that my air conditioning system was 25 years old, and to tell you that I lived with the anxiety of having to get a new system in is putting it lightly. I always worried about the cost, how I was going to afford it, and there was the ever present fear of whether I would be getting ripped off by whatever company I decided to go with. I’ve have all heard the horror stories I am sure. For me, it was double terrifying, because I knew that my system was so old that they would have to literally pull out all of the furnace and put different refrigerant in, new ducts, etc. So when I went into my phone and began googling companies I wanted to really pay attention to not only the reviews but also the importance of them being local businesses rather than some faceless entities who outsource to some place I will never go to. Thankfully my search didn’t take long because what came up almost immediately was this fine business I’m writing a review for. When I called, the person I spoke to was a) real and b) about as friendly and patient as anyone could hope for. She listened to my issue intently and shockingly said “we have someone out in Lawrence right now and so if you give us about an hour we should be able to get to you.” Upon giving her my info and all of that I hung up the phone very much apprehensive about whether or not it really would be an hour. Folks, it took 30 minutes MAYBE 45 I think and Caden was at my place. Caden took the time to clearly inform me in language I could understand what was wrong with my A/C, what he could do to fix it, but also what would be the most cost effective way to make sure this doesn’t happen again. He had an answer for EVERYTHING. He never made me feel coerced, forced, manipulated, and sold on anything. He simply gave me the straight up facts about what he would recommend I do to help my family out long term and then went step by step through the models he recommended, the cost, the financing, and how it would help me over all. He was calm, funny, intelligent, high knowledgeable, and personable. After I signed for a new system that is quiet folks (seriously, no louder than a box fan, quieter than that even) but also signed off on LOW LOW monthly payments, helped me to get signed up for the savings from Evergy and also discussed the 10 year warranty, he fixed my old POS so that my family would be comfortable and said techs would be coming by the next day to handle everything. As promised, the techs came the next day and all were professional, kind, courteous and respectful. The had my new system in within hours and my home has never been more comfortable, my children have never been more happy, and I cannot say enough good things about this company. Y’all won’t believe this, but the owner of the company came o it to check in and see how the install was going. Yes, the REAL owner. Talk about phenomenal customer service. Anyway, God forbid your AC goes out but if it does, call 1HOUR Heating and Cooling. Caden and the rest of the staff will treat you like family and you’ll be glad that you have a system installed and maintained by real people who are from a real place in the same area. Really really remarkable. Keep it up fam!

    We have been working with One Hour for a year now with maintaining our old HVAC system and their team has been great. The time finally came to upgrade the system. From there we worked With Kevin C. to spec out and pick the new system. He was honest and great at showing the options and didn’t pressure us one bit. After picking a system Blake H and his team installed it, they were professional and timely having us up and running within a day. They showed us the ins and out of the new system and how to take care of it. Overall the experience with One Hour was fantastic. Highly recommended. We look forward to continuing to work with their team to maintain this new system.

    We woke up to our air conditioner being out of commission earlier in the month. We called one hour heating and cooling they got to us quickly made the repair we signed up with their membership program and they got someone out to service the rest of our system we knew our system was very old so we talked about having someone come out to give us a quote on a new one and Nate did a great job explaining our options and making recommendations specific to our situation. Everyone met with was kind and respectful.
