"My HVAC unit stopped producing heat so I called the folks at around the clock. They offered to come out the same day and after taking a look up on our roof determined it was a faulty control board. We talked a little about the lifespan of the unit and that while it was probably going to need to be replaced in the next 5 years or so, it made more sense to simply replace the board today. So he scheduled an appointment for the following day to come back with the replacement board. 1 day later and 15 minutes of work and I have heat again."

"Haroon Sayed was great. He came by, assessed my issues with the furnace, thoroughly explained everything to me and provided me with my options on repairing or replacing the system. He was very professional & friendly man,and Highly recommend them if AC/Furnace issues"
