AC Tech Inc. was one of those few HVAC companies that were still open during COVID-19. Our central AC has broken down on us on the hottest day during COVID-19 quarantine. I called a few HVAC companies and none of them were open. I couldn’t reach anyone. Luckily I found AC Tech Inc., I was able to schedule an appointment the next day and I got my AC fixed! They are professional, fast and their price is reasonable.
