Get matched with top furnace / forced air heating system install or replace pros in Sunol, CA

"Great. They contacted me right away. It wasn't an emergency but Iti was cold, so they still came first thing on the first business day. The technician explained what he was doing and why the prior repair done by somebody else probably failed. The rate was reasonable. It's been a couple of days and it seems the furnace is working, so everything good so far."

"Smart Heating and Air Conditioning was very responsive and came out when we really needed them. We were without heat as our old furnace no longer worked and our AC was on its last leg. Mike came out to give us a quote which was the best out of three that we had. He went over all options with us and now we are very satisfied to have a new and efficient heating and AC system. They lived up to their name as well, by upgrading my thermostat to a WiFi one that added that SMART touch to my system."

"Appointment was scheduled between 8am-4pm. Waited all day for the tech (Jeremiah) to arrive. Then received a phone call a little after 3pm indicating they needed to reschedule for the next day almost at the last moment. Needless to say, we got off to a rocky start, but Jeremiah did finally show up around 5pm, isolated the problem in less then 5 minutes, showed me what to do and what not to do when changing batteries out of the thermostat, and pointed out which fuse had blown keeping the furnace from coming on. In conclusion, they made this right, I received a well-needed lesson on minor furnace maintenance, and was able to get the furnace working again. Would I hire this company again? Absolutely, and if you are having problems with your furnace, you might want to consider these people as well!"

"Absolutely the best HVAC company in the area. If you are looking for a company for your HVAC needs, look no further. It is superb in every aspect: customer service, onsite specialist who did the inspection and quoting, technicians who installed the system. Their price is extremely competitive, especially for the high end systems. I was shopping for a 80% 2-stage furnace but I ended up getting a Lennox 99% variable-speed furnace because the price was too good to pass. But it is money well spent. It is so quiet and powerful. I highly recommend Air Sharks. They actually put a smile on our faces."

"Ralph, senior tech repaired our Carrier Furnace in 45 minutes, replacing switches and other parts. It took 10 days to receive parts. Ralph estimated this delivery time."

"Great team! Mark, Sergii and Pavel replaced my furnace and installed an AC. It was a real pleasure to work with them. Mark listened carefully and provided several options for me to choose from. He was also flexible on scheduling the work to match my family needs. Sergii and Pavel performed the installation exactly as planned, kept the house clean, and payed a lot of attention to the aesthetics of the visible parts of the system. They explained to me where they'd run the lines, what were the options and why they preferred one over the other. I'm very happy with the choice of brand and model and with the installation. The team really cares about their customers. Thank you!"
