HVAC reviews in San Francisco, California

Called Laporte & Sons for an appointment to repair our (2) master bathroom showers. Carl showed up on time, did the repairs, gave us advice about our current home and the one we're building. From a company that's been around since 1959, you can tell your in good hands. Thank you so much for your help, advice and repairs. - Shawn

They've been to my home twice to fix two different plumbing issues. They answer calls quickly and both times were out to my home quickly. Their work is fast and efficient, very friendly, reasonable prices.

Quick, informative, and multi-talented. We had a weekend emergency at our house with no running water, and so we called them for help. It turns out that our issue is with the power coming into the house (something we never would have guessed). So even though they don't advertise being electricians, they know enough to debug a (previously) misdiagnosed issue. I recommend Laporte & Sons for their skill and response time.

Home mascerator pump failed. They came down, checked it all out, confirmed the failure. Got a brand new unit installed in under 48 hours. Amazingly professional, very kind, fantastic service! Strongly recommend!

Humble beginnings like theis lead to great developments. Watching this company closely.

Managed to get my old system running as new just from one visit! Will definitely keep their business card around.

Came across this company on Google Maps. Called the number and learned that Mitch & Sons HVAC was available. They serviced my ventilation unit and left me with a guide for proper maintenance and some spare parts just in case.

Asked them to replace a unit while I was gone. Came back to a neat install, no damage or stolen things noticed. More than happy choosing Mitch & Sons for my reno. Cheers!

These courageous people helped me put out a fire in my HVAC system, which got ignited from dust buildup and a smolder that happened right when they came. They literally saved my system and repaired it the same day. Great, just Great imo!

Question for Mitch or Carl: I've been analyzing the SF HVAC market trends for 2026 and noticed a massive spike in Heat Pump inquiries in the Sunset/Mission districts. I've prepared a growth audit for Mitch & Sons showing how to capture this. What’s the best email to send this report to? — Shoaib, Devtimize

When you feel like doing business with a family owned business that cares about their customers, then you need not go far! The entire crew including Mitch and Drew, is concerned about their community and customers. Service and quality first is their priority! I would suggest them to any body that would like heating, air and refrigeration service! You will not regret taking a shot at them!

In the first place, the airflow was horrible when I completed the basement and made a very little extension. The firm arrived in, installed new ducts in those sections, and connected them with the already in place system in a smooth manner. They checked the measurements, insulated, and tested air circulation. The new spaces have become as comfortable as the rest of the house.

They handled it all efficiently. Truly appreciate the team’s effort.

Their furnace tune-up is a great one that I would strongly recommend. They are fast and effective. My furnace is humming now and it is prepared to the cold. Thank you so much.

I have been a customer of this company for a long time, and the service is always responsive and quick. I recently had them for an emergency furnace repair. He explains in detail what is wrong and what is needed for the fix. He is a very courteous and knowledgeable technician. I will surely recommend them to everyone I know!

EXCELLENT company and service! No heat from our 12 year old HVAC system Called, and a tech was on-site in about 30 minutes. Tech was EXCELLENT and able to perform the repair with a very small bill. Back up and running in a few hours. HIGHLY recommended!!!

I like San Francisco Heating & Air Conditioning Services, and believe you folks will too.
Their inspectors we've previously called and used are courteous and knowledgeable. For a new furnace installation done today, two gentlemen showed up at 9 today to do the furnace install, and were done by 11. They were friendly, knew what they were doing, were efficient and worked as a team, and the teardown of the old unit, installation of the new, and the cleanup were all smoothly done.
