Hired on Thumbtack

Two technicians arrived earlier than expected after calling ahead. I was thrilled of course. It's rare that repair folks arrive early. After texting a bunch of HVAC companies these guys were one of few that agreed to do the work. Others said the job was too small. Once they arrived they got right to work. It wasn't a straight forward job so naturally I was concerned. I had nothing to worry about these guys were pros. They were done in less than an hour. I have to say these guys do quality work. They were very meticulous to make sure no air was leaking from my exhaust vent. They checked and rechecked. I was glad that their bread and butter is AC. My unit is on it's last leg. They briefly explained how they would do the work and gave me a ballpark estimate. I will be using these guys in the future. It's a great feeling knowing you have a trustworthy and meticulous technicians when you need them. They will do small jobs as well as large ones. I will gladly recommend them to my friends and family. Thank you Onzone.

They fixed my AC at a lower cost as they provided a fix instead of replacing the whole system.

I recently had a new AC and heat pump system installed by Onzone, and I couldnt be happier with the entire experience.From the initial consultation to the final inspection, the team was professional, knowledgeable, and consistently on time. They clearly explained every step of the process, answered all of my questions, and made what could have been a complicated project feel straightforward and stress-free.One thing that really stood out was how respectful they were of my home. The crew kept the work area exceptionally clean throughout the installation and left everything spotless when the job was complete. Their attention to detail was impressive.Onzone also guided me through the permit process from start to finish and made sure everything was done correctly. They coordinated all the necessary inspections and ensured the system successfully passed the HERS test, giving me confidence that the installation met all required standards.Most importantly, the quality of the installation exceeded my expectations. The finished system looks great, operates flawlessly, and performs even better than I imagined. Its clear that they take pride in their work and focus on doing the job right.I highly recommend Onzone to anyone considering an AC or heat pump installation. Professional, reliable, detail-oriented, and truly committed to customer satisfaction.
