My experience with Bellows has been an interesting one. TLDR; highly recommended and check out the Quilt system! - - - I had originally scheduled an estimator to come out an give a price on replacing a whole house gas furnace with a heat pump system but was also considering a multi-head mini-split system. The technician who came out was knowledgable and introduced me to the Quilt system. He was not pushy at all, simply said that it was a new system that showed a lot of promise. After reading a bit more about it, I was sold! The promise of efficiency was intriguing and the usability and aesthetics sealed the deal. It took about a month to really get things going, but once they started, the installation team was great! Very professional, efficient and tidy. On the third day of installation, I had inquired about the condenser unit location. It was placed in a prominent and highly visible location at the front of the house and I thought there was a good alternate location - moving it back about 5' and rotating it 90 degrees. I definitely missed the window of time when this should have been asked, and to move it would require some additional work. The initial response was not empathetic or customer satisfaction- minded, the quote for the change order was prohibitively high and I ended the phone call feeling very frustrated. Within minutes, one of the owners, was on the phone. Chelsea put on a MASTERCLASS in conflict resolution. She made a personal connection, approached the situation with humility and grace, quickly establishing empathy in both directions. Chelsea found a delicate balance between defending her business and wanting to help find a solution by sharing more detailed information about the systems and installation process, and asking questions about why I wanted to change the location. Like most customer-service facing professionals, she articulated that she wanted me to be happy with the product and service and that the company would make it right. But unlike the majority of those people, it did not come across as condescending - she was genuine, willing to explore options, and ultimately took the time to gather more information and see what options were actually available. The installation manager, Del, came out the next morning, worked with the installers to find an efficient solution to move the unit, and the system was completed within the original schedule. The two-man installation team ended up working a little later, and even on a Friday afternoon before a long weekend, showed professionalism and patience in testing the system, cleaning up, and making sure all of my questions were answered before calling the job complete. Ultimately, I am very satisfied with my Bellow's experience and would recommend. I am very impressed with Chelsea and her handling of the situation. The company, her partners and anyone working for her should be grateful for the leadership she provides. Thank you Chelsea, Del, Joed and Julian!

The Bellows service staff are competent and courteous. The office staff are also polite and…read morecourteous. The 1-Star Review reflects my assessment of an unbending schedule of fees charged by Bellows for its services. 1) The Fixed Schedule of Fees for Services is extremely expensive. How expensive?? Well, a few years ago, Bellows came out to our home to install a replacement part in the wall plate of a Toto wall-hung toilet. We provided the plumber with the correct replacement part. The actual repair required perhaps 10--15 minutes. The fee: $547 (including a service call fee of $149 plus $398 for the repair). In 2026, it surely costs more. The current service call fee is $189. At the time, Bellows HVAC was installing a ductless mini-split unit in our home, so I off-handedly requested this plumbing repair without determining the costs upfront. And indeed, I am responsible for my ignorance about plumbing charges; I should have known this minor toilet repair could cost as much as $547. That's on me. After much haggling, the fee was reduced to $400 - presumably because of the coexisting, and far more expensive HVAC installation. Still, wouldn't you have thought that a plumbing company might feel discomforted to ask for $547 for a trivial toilet repair? I learned a hard lesson about fees for plumbing services. 2) We once had an annual maintenance contract with Bellows for a reasonable fee of $300. Then Bellows informed us that only one of our three ductless A/C units was covered by the contract. Mind you, the units were actually installed by Bellows (cost: $15,500), with an average annual use of about 7 days. Did not matter. The new contract cost was $418. We should have read the small print on the contract. We paid the annual fee as there appeared to be no other option. However, I informed Bellows that I regarded the new fees as both excessive and unreasonable - and a genuine discourtesy to a long-time customer. Despite the complaint, Bellows somehow concluded that, given our previous use of their maintenance services, we had signed on for an annual subscription. And a few weeks ago, I discovered that Bellows had previously charged my credit card - unbeknownst to me - for a (now) more costly fee of $516 for a recurring maintenance contract. In effect, Bellows charged my credit card without any notification in advance or afterward. (This practice is expressly forbidden in California.) After two telephone calls to Bellows and a complaint to the BBB, (over a span of 14 days), the fee was finally removed. Bellows seemingly believes that with a refund of the unjustifiable fees, the company is absolved of any further accountability. In effect, 'We refunded the $516 charge, what more do you want?' Well, as always, Caveat Emptor! Get price quotes in advance, and be vigilant about recurring subscriptions. Do not expect a company like Bellows to accept responsibility for their contribution to any dispute, or to apologize for any inconvenience and distress experienced by the customer.

They not only did a professional and careful installation of top quality materials, they also improved existing rigid duct work with insulation, and upgraded certain areas with new significant rigid ductwork and connectors and no additional cost.

Later that evening, PG&E confirmed that our furnace had failed and was releasing carbon monoxide into our home. The next morning, I began calling HVAC contractors. None of the nine companies I contacted could help for at least a week. Fortunately, a friend from my daughter's school referred me to Jose. He answered on the second ring, immediately understood the issue, and told me his Vice President would be at my house within the hour. Just 30 minutes later, Rudy arrived and quickly confirmed the diagnosis with his equipment. Jose immediately recognized the urgency of the situation. Not only were we without heat in freezing temperatures, but our family was also at risk of further carbon monoxide exposure. By 5:00 p.m. that same day, Air Flow Pros had sourced and delivered a new furnace, assembled a six-person crew, and begun removing the old unit. By 8:00 p.m., the new furnace was professionally installed, the work area was spotless, and our home was once again warm and safe. The service was truly outstanding. Air Flow Pros delivered a high-quality product at a fair price and completed the entire job within eight hours of my initial call. I couldn't be happier and would recommend them without hesitation.
