“Eron from G1 Air was the best HVAC tech I’ve ever worked with. He serviced my AC and was awesome from start to finish—very friendly, professional, and clearly knowledgeable. He took the time to explain everything and answered all my questions. I’d highly recommend Eron and G1 Air to anyone.”

“Was able to get a same day appointment. The technician, Steven conducted an extensive exam of my unit and was able to fix the problem quickly. I highly recommend them for any HVAC issues.”

“G1-Air gave me a very reasonable quote, did the work with great care and precision and were honest about everything up front and right through to completion. They got the job done so fast after we agreed on all the HVAC equipment and were very conscientious while getting g the job done. Out of three companies I talked to they outshone the others in so many ways.”

“10 out of 10 is honestly an understatement. Based on my experience with the AC repair process, I can confidently say that G1 Air’s service is top-notch. Unlike another HVAC company I first contacted, which only attempted to fix my AC issue that lasted only 30days, G1 Air responded quickly and delivered real, lasting results. Shout out to Robert! He is truly a professional and a subject matter expert. He carefully explained every detail about the potential issues with my AC and methodically troubleshot each area to find the root cause. Robert didn’t just ‘put in hours’—he worked with dedication until the job was done right. What impressed me most is that G1 Air goes above and beyond their posted hours to make sure the customer’s system is fully functional, and their pricing is more than fair. Unlike other HVAC companies that advertise “24/7” but fail to deliver, G1 Air is realistic and flexible, tailoring their service hours around the customer’s schedule. That flexibility helped me tremendously. i cannot thank Robert and the G1 Air team enough for their professionalism, honesty, and hard work. They’ve truly set the bar for what HVAC service should be.”

“Extremely responsive! They installed our commercial unit over 5 years ago and anytime I've asked them to come out to take a look at it they showed up within 24 hours and fix the problem on the same day! The owner Justin is extremely professional and helpful. I highly recommend.”
