Installation just finished on a four-unit Quilt mini-split system. Very new product and I'm excited…read moreabout the aesthetics, usability and efficiency. 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!

I received exceptional service from Air Flow Pros during what could have been a very dangerous…read moresituation. On the coldest night of the winter, my carbon monoxide alarm went off. 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.

The new refrigerant line install looks very clean and inconspicuous against the side of the house (I couldn't even tell it was there without Jose sending me photos later on of where it was placed). The AC works like new, and the quote was very reasonable for the amount of work that was involved. Will definitely contact Air Flow Pros in the future for other jobs. Thanks Jose!

One big tip skip the promo emails. The deals you get by contacting them directly are much better than what's advertised in those marketing blasts. Booking and pricing experience Communication was easy and transparent. No aggressive upselling, no pressure to add unnecessary services. They also offer solid incentives if you schedule on a weekend and are flexible with payment options, which I appreciated. Service experience The crew showed up on time and finished everything efficiently in about two hours. They did not show up with flashy uniforms or branded trucks, but honestly that mattered far less than the quality of the work. They clearly knew what they were doing and moved with purpose. They went the extra mile by pulling out the dryer and cleaning it thoroughly from the inside, not just the vent line. Bathroom exhaust fans were cleaned properly as well, which is something a lot of companies rush through. Results This is a relatively newer house so there wasn't a ton of buildup, but the work was done cleanly and professionally. No mess left behind and no shortcuts taken. Final verdict If you want honest work, fair pricing, and zero sales nonsense, Duct Pros is an easy recommendation. I would book them again without hesitation.
