“In April 2024, I chose One Hour for a full home AC replacement, spending over $20,000. My neighbor had used them a few years prior with no issues, and because I frequently saw their trucks in our neighborhood, I trusted they were an honest company despite their quotes being on the higher side. Unfortunately, my recent experience has been incredibly disappointing. After returning home from a weekend trip, I found a cooling issue message on my thermostat. I called One Hour on Monday (6/15/2026) morning and was able to get a Tuesday 6/16/2026) appointment. The technician, Daniel, was very polite and professional. He diagnosed the issue as a faulty compressor. Since the system is barely two years old, I knew it would be covered under warranty. However, Daniel informed me that they had to order the part through the warranty company and would call me once it arrived. I explained to Daniel that waiting days for a part was unacceptable in the peak of a Houston summer—the temperature inside my two-story home was already hitting 85°F, and I have a toddler and a senior mother living with me. Daniel kindly reached out to his manager, Derrick Howard, but the customer service from management was incredibly poor. Derrick flatly stated that One Hour does not put customers in hotels while they wait for parts. I knew One Hour has a massive warehouse off the Beltway, so I asked Derrick if they had the compressor in stock. He admitted that they did, but claimed that because I was past the two-year mark, they couldn't give it to me; instead, I had to wait for the third-party warranty company they had sold me. When I asked for temporary fans or a portable AC unit to keep my family safe, Derrick unhelpfully commented that "customers past two years don't get that." (Thankfully, Daniel was eventually able to secure some temporary cooling equipment for us anyway). After enduring two miserable nights without air conditioning, a team finally came out on Thursday (6/18/2026) to install the new compressor. The only saving grace was that it rained for a couple of days, which kept outdoor temperatures slightly lower, but the thermostat inside still read a stifling 85°F. One Hour needs to establish a much better, faster process for retrieving replacement parts from the warranty companies they directly partner with. Their own paying customers should not be left stranded for days in dangerous summer heat.”

“It's not like your A/C unit breaks all the time and you already know all the great repair and service firms. So, I looked up their reviews and the competition and saw similar reviews. What separated this company was their BBB A+ rating and I could see why in the technician that came to my house. David, asked me the right questions, understood that I knew what the cause was and I wanted a solution. Dave was about to tell me several options they provide, and I told him just give me the right solution, so I don't have this problem again. I got the solution I was expecting and signed up for them to execute the solution. David was great to work with and was very knowledgeable. I would definitely call on them again, but hopefully I will not have to.”

“I highly recommend Ricardo for any AC maintenance or tune-up service. He was extremely professional, knowledgeable, and friendly throughout the entire visit. Ricardo took the time to thoroughly inspect the system and clearly explained everything he found in a way that was easy to understand. What I appreciated most was that he was honest, patient, and willing to answer all of my questions without rushing. He made sure I understood the condition of my AC system and provided helpful recommendations to keep it running efficiently. It’s clear that he takes pride in his work and genuinely cares about his customers. If you’re looking for someone reliable, professional, and thorough, Ricardo is the person to call. Excellent service from start to finish!”

“Customer service: great. Scheduling: great Updates on where you are in the queue: great Have questions? Get answers fast. Linnell is amazing. Great guy. Talked us through what he was doing and what our next steps are. No hidden prices or gotchas and most importantly, my house is cooling again! Thank you all for your help!”

“Our issue was not resolved. The technician came, diagnosed our system without testing the low voltage as stated on his inspection sheet, overcharged us to replace a capacitor, contactor, and transformer at $1278, and then the transformer and contactor blew the next day. We contacted them for a warranty callback, he arrived and replaced the contactor and transformer then proceeds to tell me that he has to charge me $300 for a low voltage scan which then I proceeded to ask for a supervisor, Mr. Thinhn (I apologize if I spelt your name wrong), who become unreasonable and refused to budge when I asked why he was charging me more money for a diagnosis. He replied "that the service was completed and the A/C was working the day prior, so this is a new issue." This whole experience was predatory. The tech showed me the prices of the parts the first day and they were going to charge me about $450 just for a capacitor. That is absurd and extremely unprofessional to be price gouging and then proceed to hide behind the reason "you pay a premium for premium service." I refused to pay the $300 and then the tech decided to leave with my A/C's issues unresolved. I'm not sure what I paid for then. While I can't speak for the company as a whole, the franchise in Houston, TX is responsible for this mess. (Edit 05/31/2026: The capacitor that was replaced also turned out to not be broken. I went and bought a capacitance tester after a new tech from a different company informed me that the old capacitor wasn't even bad (it tested like it was brand new) and i paid a "premium" for that part. So due to that issue, it seems like the incompetence of that just bears fruit from the poisonous tree of anything else that was performed.) I do not know how to test the transformer without it being connected to power or the contactor.”
