JW Hanson Heating and Air - North Bay Area HVAC, Santa Rosa CA

We have had issues with our instant heat boiler for years. JW Hanson sent out their most experienced boiler technician. He resolved the issue within 15 min. He then inspected the entire system and told us what issues we should remedy so that the boiler would be more efficient.
I highly recommend this company to anyone with a boiler or for any heat issue.

The people on the phone were nice. We had a Nest thermostat installed. Fair price. On time. Nice neat job.

JW Hanson Heating and Air is the best of the best, I have been using them for 15 years now and I highly recomend them.

We've had 3 homes in Marin in 34 years and plenty of HVAC experiences. Hands down Hanson's provided the most professional, timely, and valuable assistance we've ever had servicing and installing heating systems here. Quality team, managed by a calm, reassuring detail freak- Will Hanson. You can't go wrong with these people.

Exceedingly competent and responsive to your needs. They keep up on new technology and give valuable advice. I have had an ongoing relationship with this company and have never had a less than outstanding experience.

As a manager of a small complex of buildings I appreciate the skill and knowledge Will and his crew bring to challenging heating installations and service. They are my first choice when I need service or repairs.

One time, On budget, clean work, good personality, fair price. One happy camper. I tried several other companies and had from no-show to rude and one guy was downright insulting. I would do business with Hanson anytime.

I've had quite a lot of experience with the building trades, though not as much as my fictitious birth date would indicate), and I can't recall ever having a more pleasant and productive relationship with a company and its workers than with JW Hanson. I would recommend them with confidence to anyone.

In the winter our heater would quit working on cold days. Hanson did an outstanding job of analyzing our heater problems and recommending an upgrade. Hanson did a very professional installation and tutorial on the use of the new system. I highly recommend this company for all HVAC work.

Hanson replaced one furnace and serviced our other one. What a improvement! More air moving and much more efficient unit. Additionally, their staff was knowledgeable and excellent with clean up. Recommend highly.

My entire experience with Hanson Heating & Air has been exceptional. From my first phone call to schedule a boiler maintenance to the actual service call. The office staff was friendly, returned calls promptly and confirmed the service time and date. Will showed up on-time, quickly diagnosed a maintenance issue and fixed it. A service call doesn't get any better. I highly recommend Hanson Heating & Air.

First used them in my previous house which had hydronic heating. They (unlike other heating contractors) said my boiler could last another 25 years, longer than most new ones. They replaced the pump with a quieter more efficient one, as well as one of the valves, and a couple minor parts. It has run flawlessly since. When I moved to a house with forced air and AC, they just had to inspect the system. Price was VERY reasonable.
