They helped repair my AC quickly and professionally. Fair pricing, great communication, and they cleaned everything up after the job was done. Very happy with the service and would definitely recommend them to anyone looking for reliable HVAC work!

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.

I had two thermostats and 4 ceiling lamps installed. Staff did a wonderful job installing and making my AC work again. They were hardworking and did a great job. I am very happy with their good service and would definitely call them again when I need any AC/heating work done. They also did a great job installing ceiling lamps.

OMG they were a lifesaver! After a power outage my old A/C would not come on in the middle of this heat wave were having. I went through thumbtack and received several notifications back of companies that wanted to help. Ozone was the first one. I was thrilled that they could fit me in at a 2 PM to 4 PM timeslot as I was having people over for dinner tonight and expected 92 weather. He got here he was very quick clean explained everything and reasonable. I was a little hesitant because I didnt see many reviews but its because theyre a newer company and they just havent got them yet and I figured Id take a chance. Boy am I glad I did. Theyre coming tomorrow to give me an estimate on two new heaters and two new air conditioners.. I was very happy with their service and you will be too if you find yourself in need you cant go wrong with these guys!5 star for sure!!
