Reviews of local pros in Cotati, California

Signed up for annual HVAC maintenance. Matt was professional and performed maintenance on my heater, change my filters, took pictures and provided a service report with recommendations. I would highly recommend Next Day Air and like that they are local.

Great customer service! I am very happy with their work, very thorough and documented everything for me. From start to finish they have been wonderful!!

The tech arrived quickly and determined both the reason why the furnace wasn’t functioning and the additional maintenence it should have for a longer and more efficient lifetime in service. He patched things up so the furnace will work until we receive the parts needed for a full repair. Since I was interested, he explained what he was testing and the meaning of the results he was finding. An A+ experience.

I had an emergency AC issue on a weekend and Eric at Next Day Heating and Air was the only person that actually picked up my call. Amazing! Rohan showed up within 3 hours and fixed our AC issue same day. Didnt have to wait for parts, their truck was well stocked. With the temperature at 104 that prompt response and repair was greatly appreciated. Thank you so much Eric and Rohan. Highly recommend !

The Technician showed up on time and he diagnosed the issue perfectly. A fair cost was given to us and the appointment for troubleshooting was very reasonable. Other companies i have used charge much more just to stand on your doorstep, but not Next Day. We gave the green light to fix it and are confident the job will be done correctly. I was shown the problem and i agreed because the man who installed it did a crappy job. The Technician gave us all the information we needed to decide the best option. Everything went really smooth for us. Try this company. I believe you’ll like their knowledge, informative content and politeness. Good price yes, but so is reliability. 5 Stars….

Eric and team are great to work with. They have helped us with HVAC replacement in two houses. Happy to work with them again highly recommend.

Next Day installed a new heat pump at our home. Everything went very smoothly and it was amazing to have central air over the summer months. They had really great pricing compared to other HVAC companies too.

If your not sure who to call to fix your heating issues this is the place. Our heater stopped working on what felt like the coldest day of the year. It happened to be a Friday evening and I was afraid we would be freezing all weekend. I called Next Day Air and Heating and Joseph was there within a few hours. He came through at 7pm and had the heat working by 8. He took pictures and videos and explained every issue so we could understand. From the receptionist, to the cost, to the friendly service this place is the best!

I had a fantastic experience with Next Day and Air AC Service. They were fast, professional, and incredibly efficient. My AC issue was fixed the very next day, just as promised. Eric was knowledgeable and friendly, and the whole process was smooth from start to finish. Highly recommend them for anyone needing quick and reliable!

Our service tech Matt was ontime, very knowledgeable about our heat pump HVAC & air system, performed routine maintenance & uncovered critical faults in installation of our 5 yr old system. We are very satisfied with our service.

Next day heating and cooling are an amazing business to work with, end of August 2025 my Dad passed away a few days later the air conditioning went out! Hottest days of the summer, (one of my siblings joked that dad was trying to let us know how hot it was where he was) well anyway Next Day hurried to get air conditioning unit replaced so my mom was comfortable.
So grateful for good people. K Stoney

We've been incredibly impressed with Next Day Air Conditioning. The team is not only professional and knowledgeable but also extremely flexible. Running a dog boarding facility in Sonoma means we have unique and often unpredictable schedules/situations, and they have always been willing to accommodate us, getting the job done quickly and efficiently every time. Their communication is great, rates are reasonable, and they offer service plans with discounts. We highly recommend them!

Greg, Craig, and Rohan teamed up to diagnose and repair my tankless water heater within a very tight timeframe. They succeeded despite a slow manufacturer who was holding up the necessary parts. In order to finish on time, they drove to Sacramento to get the parts themselves and orchestrated a "just in time" completion. This is exactly the kind of team you want supporting your critical systems at home. Thanks again.

Replaced my 15 year old HVAC with Daikin/Goodman dual fuel heat pump system. I got estimates from 4 HVAC companies and decided to go with Next Day Air and Heating for different reasons. I was satisfied with my encounter with their personnel, from the day I made appointment for estimates until the completion of the job. Professional, straight forward and the price was right. Eric came for the estimate , I was sold with his knowledge on my needs not like the other 3 companies where I felt that they’re not familiar with their products.

Today we had Next Day Air and Heating here to fix heating and thermostat issues.
They were very professional, courteous and personable. Rhoan was absolutely hands-on and willing to answer all my questions. They earned a five star ratings without a doubt. I highly recommend this business to all of AMERICAN CANYON residents.

Our heater stopped working on a Friday morning, they sent Rohan out the same day to see what was going on. Rohan was thorough and professional during his diagnostic tests. He explained the problems with the furnace clearly. Craig made sure to get the parts needed for the repair ordered ASAP. Next Day Air & Heating had our broken furnace back in working order first thing on Monday. They did the backend work to make sure our furnace was still under warranty, so the parts were covered by the manufacturer and took great care of us! This company takes pride in their work and their customer service, and it shows in their personal interactions with customers. We will continue to use them for our heating and air, and will refer our family/friends to them.

What a great experience with Next Day Heating & Air! Thank you so much for everyyyyything!!! Great customer service, skilled technicians, competitive fair pricing and all with a smile and a team approach! Give them a call, you won’t regret it!

Actually picked up phone on a Federal Holiday and was able to schedule a next day service. Selling my mother's home due to death and needed someone asap since i live 4 hours away and was only going to be in town next day. Technician showed up on time and was very knowledgeable and explained the whole process. My moms Unit was the original from 1984 and tech was able to point out a couple issues that I could fix myself to save money ( since it was going to be listed for sale as is) and explained how good the unit was and should have many years left. Past technicians have recommended replacing without testing due to age,
Really appreciate the honesty and integrity of this company and will recommend to anyone needing HVAC help.

They did an exceptional job. They were able to help my grandma get her pellet stove running again. They were able to get to her quickly which is huge since this was her only source of heat. She said they were friendly and went above and beyond helping her. Highly recommend this company

Awesome job! I had trouble getting anyone to work on my Daikin mini-split units that would not turn on. The weather was cold and the house wouldn’t heat. It was a weekend and service is hard to arrange in Oakhurst under those conditions. I called Next Day Air and Joseph was able to identify the problem the same day (a Sunday). Joseph had arranged for the parts and repaired the units within 24 hours. I can’t say enough good things about Next Day Air and Joseph. 5 stars!

Craig was super fast in scheduling our service. We just moved into our manufactured home. I didn’t know if it was our thermostat or furnace that wasn’t working right. Rohan had time today and was able to ascertain that our furnace had never been “fired” up. He turned it on. And got everything working. I can’t tell you how relieved I am! Believe me, no one wants to move to a new place and have something go wrong. I highly recommend Next Day Air & Heating.
