HVAC Services Have Great Guarantees
Our customers love what we do because we treat them like the neighbors they are to us. While we carry the One Hour name, were an independently owned and operated business with a personal investment in the local community. We back our work with a 100% satisfaction guarantee, provide StraightForward® pricing guides for your benefit, and will pay you back for being even one minute late to an appointment.
Mason is an excellent technician. His assessment and remediation of my system were excellent and greatly appreciated. His diligence also provided the best solutions for the best performance of my HVAC while ensuring the best value for my dollar! Thank you!
Chase was professional and efficient. He communicated the problem very well and he solved it quickly. The price was fair and he was neat and clean.
Just prior to listing our home for sale, our heat pump died. We contacted One Hour Heating and Air Conditioning, and they sent a technician that day. He was professional and knowledgeable. We could repair it or replace it. Given its age, we replaced it, and the installation was done in a few days. Tremendous service! Fast forward to our new home. We opted to replace both 21-year-old HVAC systems (upstairs and downstairs) and there was no doubt which company to call, One Hour Heating and Air Conditioning. The contracting process was simple and easy, and the price was very reasonable. The team of technicians, led by Ludwig, were on-time, professional, and did a great job and they thoroughly cleaned up when they finished, which was nice. After two transactions in 6 months, with both installations having gone smoothly, I can’t say enough and highly recommend them.
Today I received service from Craig Moss of Modern Mechanical and he was AMAZING!!! Craig was professional, punctual, AND trustworthy. I say he’s trustworthy because as a first time homebuyer, I got three different quotes and Craig was the only person to teach me about my AC system, the home maintenance plan, and how to smartly save and invest for a newer system a few years from now. AND he SAVED me a ton of money!!!💰…Thank you Craig!🙂🤗 One Hour is the only HVAC service that I will be using from now on!😎
