Our AC went out on Monday and I contacted 3 other companies and none of them could come out until next week. I called 1hour heating and air conditioning. They came out yesterday. Robert was great! He tested the unit and found the issues. We needed a replacement plus our furnace was really old. So Steven came out today and put in the new AC and heater. Steven did an awesome job and took away all old equipment. We're very happy with the job they did and so glad we didn't have to wait another week. We highly recommend them!

Called One Stop Heating and Air Conditioning at 7am on a Monday during the recent heatwave, half expecting to wait days for an appointment. Instead, they gave me an 8-10am arrival window that same day — and Robert showed up by 9am. He listened to my description of the problem, then explained in plain, easy-to-understand terms what he thought was going on. He tested his theory, and he was right. Even better, he had the part on hand in his van, so the whole repair took about 30 minutes. The price was fair, especially given the speed and same-day service. It's also nice to support a family-owned business instead of a big corporate outfit, especially when the service is this good. One Stop Heating and Air Conditioning has earned my business going forward — they're now my go-to for HVAC maintenance and repairs.

Steven was excellent. Looked at all possible issues that could be causing my AC unit to fail, until he finally came up with the culprit and fixed it. Really appreciate his tenacity to figure out the correct solution! Now, I’m enjoying cool air again throughout my house! Thx Steven! 👍🏻

I had an excellent experience with One Hour Heating & Air Conditioning. From scheduling to completion of the service, the entire process was smooth and professional. The technician arrived on time, was courteous, knowledgeable, and took the time to explain everything clearly. They quickly diagnosed the issue, completed the repair efficiently, and made sure everything was working perfectly before leaving. I really appreciated their honesty, attention to detail, and commitment to customer service. It's refreshing to work with a company that values professionalism and quality workmanship. I would highly recommend One Hour Heating & Air Conditioning to anyone looking for reliable HVAC service and will definitely use them again in the future.

Had a really good experience with One Hour Heating & Air Conditioning. They responded quickly and were able to come out within an hour of my call, which I really appreciated. Robert and Steven were great to work with—both were easy to talk to, explained the issue clearly, and walked me through my options without any pressure. The whole process felt straightforward and comfortable. The quality of the work was solid, and even the permit inspectors mentioned they were impressed with how everything was done. If you’re looking for a reliable company with good people who know what they’re doing, I’d definitely recommend them.
