William Stewart

I was very happy with your technician who came yesterday. His name was Don, and he answered all of my questions with extreme patience and thoroughness. He explained Co2 and installed an alarm. My neighbor is looking for a new furnace, and I will definitely recommend your company!

We have been using Stewart ever since we bought our home, as did the previous owners who lived here for over 40 years. Great customer service and timely repairs if needed. Their scheduled maintenance program is a good way to make sure our systems are operating up to snuff. Service Technician Jamie J. is wonderful. He is knowledgeable, courteous and personable. We are sticking with Stewart HVAC.

I called Stewart heating and air per recommendation from Asure Extended Warranty. Don came on time and was very friendly and professional. He was very thorough with his inspection and found the problem quickly which was a capacitor failure. He replaced said capacitor and sure enough, the HVAC was working again! Don was a savior and Stewart Heating and Air a definite keeper! We decided to dump the other warranties we have with other companies and signed a maintenance agreement with Stewart's. Thanks so much, Don! Blessings to you and yours!

Jamie was thoughtful, explained everything and he was kind to my dog! Most importantly, on a hot day like today, he got the system pumping cold air in the house again. Seriously, you can tell good, honest people who work hard and do good work. Great experience all around! Thanks Jamie! Services: Repair HVAC, HVAC system repair, HVAC system maintenance

I had an upper lateral blockage in the evening and they were able to come out the next morning. The service person, Terry, showed up right on time 1st thing in the morning. After fixing my problem and cleaning up all the messy overflow, he advised me to watch for potential problems. He then offered a discounted rate to add an earthquake gas turn off valve since he was already out on the service call.

I had some other issues and took the opportunity to have him fix 3 other items. I have used Stewart Heating and Air for installation of my A/C last year and was very impressed with their workmanship. They are professional, flexible and do not gouge on pricing. I will use them for most of my HVAC and plumbing needs in the future.

I actually think it is disgraceful that Stewart charges $110 to do a 21 point inspection of each heater in a home. This is the equivalent of a mechanic checking your oil fluid level, transmission fluid level, tire air pressure, etc. and calling that a service. It took all of 15 mins for your rep to "check" two heaters. What a waste of my money! Don't worry about not posting this feedback. I won't be hiring you to do this ever again. What a rip off.

Don arrived today, on time. He maintained the two different furnaces we have, explained why I didn't need a third filter (yay!) and left a brochure with me (after explaining it) regarding PlasmaAir. He was professional, efficient and very knowledgeable. He answered all my questions, and generally, this was a wonderful experience! Service: HVAC system maintenance

Huge thumbs up for Stewart HVAC! Yancy, Brian and Aaron did a great job installing our new furnace and A/C and their bid was very reasonable. They also coordinated removal and reinstallation of some fencing and railing to get the old unit out. Thanks so much to Justin and team! Recommend them highly.

Heat pump stopped working. Angelo trouble shot the problem. Replaced fuse but still not working. Then tracked the short to a broken wire in the thermostat. Arrived on time. Methodically solved the problem. Pleasant demeanor. Stewart Heating seems to hire smart and reliable people. Always 5 star service. Service: Heating system repair

Contractor did not obtain a proper permit. Online permit that they got was for "like replacement". The Walnut Creek City permit office inspector concluded that the scope of the project that they started is not covered by "like replacement" permit as their project is complete overhaul of the HVAC system and is not "like for like" (see attached inspection report). Contractor is a big company claiming a lot of experience in the industry. Contractor's salesperson sold us (at the premium price) the technical solution that does not fit to our house.

When their workers faced the most challenging part - connection of downstairs ductwork to air handler in the attic - work slowed to a halt and contractor started inventing reasons to upsell additional work and cover for unworkable solution with delays. During the sales process we asked the salesperson repeatedly if they need to bring a more technical person to verify the solution.

They had two weeks before the work started to re-evaluate and propose us something more suitable. Instead, they pressed on with the faulty design. The Walnut Creek city engineer has concluded that had contractor adhered to the proper permitting process, the inadequacy of their solution would have been for sure discovered by city inspectors and this project would have been rejected. Instead, they cheated and got the online permit for "like replacement" that doesn't require a review.

Their trying to blame shift their faulty design on trusting unexperienced homeowners is only showing their lack of integrity. Since the initiation of this project Justin Stewart and the team working on the project did not have any idea of what they are doing. Before starting the project Justin Stewart knew that they don't have a proper permit which was fraud by itself, however it did not stop him from taking from us $11,000, bringing to our house unprofessional workers who worked under influence of either drugs or alcohol, neither wearing masks nor vaccinated.

As a result, unethical and fraudulent actions of Stewart Heating and Air: during the project, we called PG&E regarding gas leak, and uncapped exhaust leak and electrical wiring. As of today, our house doesn't have the HVAC, since the old one was destroyed by the fraudulent and negligent action of Stewart Heating and Air, Inc. Besides, Stewart Heating and Air, Inc. is trying to put some additional pressure on our family by blackmailing us with the second letter regarding lean on our house and trespassing on our property (the case # 21- 22149 with the WCPD).

We already mailed the Stop Work Order to the Contractor, and we demanded our $11,000 back, due to fraudulent permit, lack of integrity, severity of negligence, and blackmailing actions. Besides, Stewart Heating and Air, Inc. must not only return the money that we have paid but reimburse us for all damages that were done to the ceiling in the house and the garages.

We regard all lien letters as the blackmailing actions from the Contractor that is acting from the day one in the bad faith, pursuing monetary gain, instead of following all appropriate steps and procedures to get the work done and being paid accordingly. The project is currently frozen, all evidence is preserved for the CSLB investigation. We expect to process with different contactors, only after the investigation is finished, and monetary reimbursement from by the Stewart Heating and Air, Inc.
