Heating & Cooling in San Francisco

Professionally installed. Competitive price and offered a veterans discount. I would definitely recommend A1. A1 installed my Trane furnace 3 years ago. They did an excellent job then. I needed a brand new AC installed (I lived in Almaden for 20 years without one). Also got a bid from Valley heating. Valley never followed back up, while A1 sent the CEO Brad to my house to answer some extra questions I had. A1 also offered me an extra discount since I am a veteran (Thank you for supporting military/veterans!!). Installation of the Goodman AC took two days, but they couldn’t get the AC and furnace to communicate since different brands ( they should already know that in advance, but not going to downgrade my rating for it). They sent William out to troubleshoot and fix it on 3rd day (ideally total install should not exceed 2 days IMO). All appears to be working great. I would definitely recommend A1 for your heating and AC needs.

watch out - they charge a service fee for quotes

David S. provided a quote for a ducted mini split. He was very professional, clearly knew his stuff, suggested a creative solution and delivered the quote and follow-up responses very promptly. We ended up going in another direction for other reasons, but I would absolutely reach out to Pyramid and David for any future work.

Great service. Stayed in communication throughout the entire process. Professional and efficient.

The technicians that came to install our HVAC system were super friendly and accommodating to my many requests about locations of the furnace, vent pipes, the condenser wiring, piping, and the condenser itself. When I asked for a 90 degree boot feeding two registers so the piping could stay high, a technician made a run to a store and found them. I want to give a shout out to Danny Aguilar who installed the furnace with Edgar and Victor. Grant Duran with Jose and Richard did an amazing job installing the vent pipes. Finally Adolph Garcia with Gabriel and later several other technicians I previously mentioned all worked to install the AC system (condenser and its plumbing + electrical). They worked late into the day to complete the job. I was very demanding in where I wanted things installed and requested changes on a regular basis but in all cases I was accommodated.

Excellent, they find the problem and fix the problem. I am satisfied, very professional Valentino, the technician, very professional

HADDEN HEATING AND COOLING WAS VERY KNOWLEDGEABLE ABOUT HEATING AND COOLING. THEY KNEW RIGHT AWAY THAT IT NEEDED CHARGED. THEY WERE POLITE AND THE PRICE WAS OK TOO. THE GUYS WERE VERY HELPFUL.

This company was great. The owner came in and did the estimate. He was willing to work with us on the price and estimates. I was very impressed with them. They did an excellent job on my heating and cooling system. I have had no problems with this company.

They were professional. They came right out and gave me an appointment. They were excellent.

I get why Sandium has great reviews. They're install services are great and since 99% of systems probably work reliably for years that's the extet of dealing with them. But their after service support has been awful and if you're stuck with a system that fails prematurely then good luck. We paid $40k+ for a brand new Samsung heat pump system and all new ductwork last year. One of our attic air handlers died on Dec 11 taking out our bedroom zone and leaving us with nothing but space heaters for our bedrooms during our first winter with the brand new system. Took till early Jan to finally get it fixed which left us with space heaters over the holidays. Seems crazy to me when we paid a very significant premium for sandium over other competitors truly believing they were the best. Once the temporary fix was in the technician realized that the bearing failed because the cabinet was deformed. That could only have happened in original transit. They ordered a new air handler which took 3+ months to arrive. Now I'm being told this can't be installed till June or July because they're too busy. Given the system is likely to fail when under load this means there's a pretty good chance I'll lose cooling during a heat wave before they can get the new unit in. I'm by no means excited to get this new unit in as it'll be very disruptive and require removing our existing closet built ins but it has to be done. This whole situation is incredibly unacceptable. To take 6-7 months to fix a brand new system is crazy to me. I've really tried to be patient on this and it pains me to leave this review but hopefully anyone who reads this can see how unacceptable this situation is. I'm not even going to get into the back and forth with Samsung and the supply company since I made the check out to sandium and so they should be responsible for the system. When you hire an hvac company, turn around time for fixing things matters. I totally get that things can go wrong but the response to things going wrong matters. Sandium is too busy with new work to bother with that. It's not like fixing this is a favor to me. It's getting my system into the condition it should have been in on day 1.
