One Hour Heating & Air Conditioning

One hour heating and air conditioning did a great job for us! We had a capacitor go bad and they had us back up and running in no time! Good communication and good pricing. I would highly recommend!

We recently had a new HVAC unit installed and could not be more impressed with the experience. Under the company?s new ownership, everything from the initial consultation to the final installation was handled with professionalism, honesty, and attention to detail. The team was knowledgeable, courteous, and made sure the system was set up for long-term efficiency and comfort. It?s clear this company is focused on building lasting relationships with its customers, not just completing one-time jobs. We feel confident knowing we have a partner we can rely on for years to come and highly recommend them to anyone looking for quality HVAC service.

Have them a call spoke to Don they had a tech to my house within the hour and got my house cool again would definitely recommend them

They got to us in a timely manner! Definitely would use again!

Really impressed with One Hour! AV (my tech) showed up on time, was super professional and very respectful. He was knowledgeable and explained everything clearly. Got my system running, worked quickly while not cutting corners, and even gave me a few maintenance tips. Friendly, honest, and just an all-around great experience. I'll definitely be recommending to neighbors in Marietta and will be using them again! Very trustworthy and just simply great service.

I couldn’t be happier with my experience with One Hour Heating & Air Conditioning. From the moment I scheduled the appointment, their team was professional, courteous, and incredibly responsive. They arrived exactly when they said they would—no waiting around wondering if someone would show up—and they walked me through everything they were going to do before getting started. Professional, honest, and reliable - I highly recommend One Hour Heating & Air Conditioning.

I recently had an HVAC technician named Eric come out for a service, and I couldn’t be more impressed. From start to finish, Eric was incredibly thorough, professional, and knowledgeable. He took the time to carefully inspect everything, explain what he was doing, and answer all my questions with patience and clarity. What really stood out was how detail-oriented he was—he didn’t rush through anything and made sure the system was running efficiently before he left. It’s clear he takes pride in his work, and it gave me peace of mind knowing my HVAC system is in great hands. Highly recommend both the company and Eric if you’re looking for reliable, top-quality service!

Great experience! On time, courteous and very knowledgeable. I also appreciated that they didn’t try to upsell me, while also letting me know what we want to keep an eye on over the next 12-18 months. Highly recommended!

A company that you can trust - good people at a completely fair price and always reliable. Would highly recommend to anyone. You will be in good hands!!!
