Reviews of local pros in Cotati, California

Professional, knowledgeable and thorough from owner to team. Really great experience with Next Day Air. Their commitment to quality work shows. Our furnace went out, and after I called, they stopped by the next day! We were quoted a fair price, and also they offer 0% financing which was a no brainer.
We need up having both a water heater and furnace replaced by them, and are very happy with everything from the diagnostic, the quote to scheduling and install. They warranty their labor as well as equipment so it says a lot about the level of quality they stand behind.

Rohan was our technician. He was very communicative, professional and helpful with suggestions. I highly recommend. We are going to have more work done. I hope it goes there way.

I called for a second estimate on a heat pump. An appointment was set up for a few days later. Dustin did an excellent job describing what would happen, the advantages of a heat pump, which I had asked, and a comparison with a new furnace and air conditioning. He also suggested I compare products through the AHRI numbers of the two manufactures. While the reviews recommended the other manufacture over Bryant, the third part comparisons indicated that Bryant was more efficient and had the same or higher overall ratings. Once I chose the Bryant equipment, installation was set up a few days later. Jose walked me through the process and explained what he was doing with each question. I am thoroughly satisfied with the company, the equipment, and their service. I also liked that they offered not only a 10 year guarantee on parts, but also on labor. I highly recommend Next Day Air & Heating.

Prompt, efficient, and affordable service.
My radiant heater stopped working. I called two other services . One. gave me a high bid and said I needed a new valve. Next door confirmed I did not need a new valve , but an electric board.
They made sure one would be available the next day. They came early in there rain and fixed it .i am so grateful; my house is warm again.
I highly recommend Next Day Heating.

I’m so impressed with the customer care from this company. My initial phone call led to a next day appointment to check out my pellet stove. The technician, Joe was very knowledgeable and explained the workings of my stove. I’m definitely recommending them. They absolutely live up to their name!

We had an outstanding experience with Next Day Air & Heating. Our home is 70 years old and posed many challenges for installing a modern heating and air conditioning system. Aaron, Ky and Eric were absolutely incredible—professional, highly skilled, and impressively creative in problem-solving every obstacle that came up.

They were responsive with timing, clear in communication, and their workmanship was top-notch. What impressed us most was their ability to navigate the complexity of our older home and still deliver a seamless, efficient installation. And, they were very price-competitive!

It’s rare these days to find a team so dedicated, capable, and solution-oriented. We couldn’t be happier with the results and can’t recommend Next Day Air & Heating, especially Eric and Aaron, highly enough!

Every person we spoke to or worked with along the way was very friendly and professional. The service was prompt and was the best pricing we found when comparing with other companies. They were honest and didn’t try to up-sell us on anything. We will happily work with them again!

Thank you Next Day Air. These guys and gals were amazing. Their office staff was friendly and informative, technicians were professional and not at all pushy and pricing was fair. They got our heater up and running and were meeting in a few months to discuss replacement in the spring time.

Wow, Next Day Air & Heating? More like Same Day Air & Heating! Jose did a great job and was very professional and efficient. They have also cleaned/replaced our home air ducting system, installed a heat pump and installed a 4 filter home water purification system. They are prompt about maintenance for filter replacements. Can't ask for much better. They are experts and our go to for HVAC/AC/Heating needs.

I had an excellent experience with this HVAC company! Jose and Stefan installed my mini split system, and the whole process was smooth from start to finish. The installation was completed in just one day, and they worked efficiently while keeping me informed every step of the way. They were professional, knowledgeable, and took the time to explain each part of the process. I really appreciated how they kept the work area clean during and after the installation. At the end, they walked me through the system’s operation with clear, step-by-step instructions. I’m very happy with the results and would highly recommend this company to anyone looking for quality HVAC service.

I’ve been living in a freezing cold house for years and finally decided to deal with it. I found Next Day on Nextdoor. It had great reviews. Dustin came next day, walked around and recommended a heat pump. He was so friendly and knowledgeable. They contacted me after I signed the contract and within the week, Kai and Jesse, who did the installation, arrived, and within 2 days my house is perfectly warm. Kai and Jesse were fantastic. They were very respectful, greeting me with a genuine smile and handshake introductions. They were very friendly, worked hard, and didn’t need me at all during the installation. They left the place perfect, no trash left behind and the work looks great. I highly recommend these professionals.

Responsive & professional. I needed all my ducts replaced due to mice. They came out quickly, mapped my system and suggested ways to get better heating and air flow in my system. Very fair pricing and options. They explained everything in detail before the work began. I love their feature that texts you where the technician is on route to service. The installers were very professional and quick. Would highly recommend them.

I am writing this review, to express my profound appreciation for the exceptional work recently completed by Kailen and their dedicated installation team. They undertook the comprehensive task of removing our outdated heating and ducting system and seamlessly installing a sophisticated new climate control solution.

The entire process was handled with remarkable professionalism and efficiency. Every member of the team consistently demonstrated a high degree of skill, conscientiousness, and unwavering courtesy. Their commitment to ensuring our complete satisfaction was evident throughout the project.

We were particularly impressed by their impeccable punctuality and meticulous attention to maintaining a pristine work environment. They adhered strictly to the schedule, arriving promptly each day, and diligently ensured that the premises were left immaculately clean at the close of every workday, minimizing any disruption. Furthermore, the comprehensive training session provided on the final day was incredibly valuable, empowering us with all the necessary knowledge to confidently operate our advanced new heating and air conditioning system.

We are absolutely delighted with the enhanced efficiency and comfort now provided by our new system. This entire experience has left us immensely satisfied with both the superior quality of the equipment and the outstanding service delivered by your company.

Next Day Air & Heating did a great job of installing my new furnace. Aaron & Stefan were both hard working, professional, instructive on my operation of the furnace, lastly very nice & friendly!
