ONAS Heating & Cooling Corp. exceeded my expectations. From start to finish, their team demonstrated a high level of professionalism and technical skill. The installation was not only flawless but also extremely clean and well-organized. It’s rare to find contractors who care this much about both quality and presentation. Highly recommend!

I installed a four zone, four head Tosot heat pump for my old house in downtown. Amir and Arsalan were amazingly helpful in guiding me through my brand selection and size/qty decision. The installation team was also very communicative and checked in with me for all the setup and placement decisions. The system is working much better than I expected and I’m quite pleased with the process and the outcome. Highly recommend these folks.
