I called and spoke with Ron. He was responsive and answered my questions in a clear way. Their work was quick and they kept me posted with updates. read more

Marty refused to come look at our AC unit, which stopped working a year after install because it was mentioned it could be a mouse. It is a dangerously hot week, 84 at night here, and I have a one year old baby. Marty did not care. She would not send help. We currently have no AC and baby is sleeping next to box fan. read more

I highly recommend North Bay Air! What a pleasure and relief to find such a honest, hardworking, professional company to work with! Excellent communication and response. I had to have four ducts under my house replaced. A great price and excellent service- what more could you ask for?! read more

Ron and his team have been taking care of our two-zone hvac system since the original install 17 years ago. They have always been reliable, professional and skilled in their work, major and minor. The fan in our upstairs Trane unit failed, causing a cascade of issues. Other places just wanted to sell a new unit. He replaced the motor, burned controller, limit switch, and we're all good. read more

We had a tech come out today to switch out the thermostat which wasn't reading the temperature in the house correctly, so the a/c never turned off. He got the thermostat switched out, checked out the ducts and the freon level. Friendly and efficient read more

My initial tech called in sick so the appointment got canceled. When I called to reschedule the office let me know the owner was out running around to pick up the slack and could come preform the service. The owner was great! Super simple fix of my AC unit. He did let me know my unit was past it's prime and would need to be replaced soon but showed me a couple things I could do to prolong its life. There was no push for new equipment or a big bill at the end of my service. These guys won my business from here on out!!! read more

The service level we just received was outstanding. These guys really know their stuff and get it done fast! They just pulled off a diagnosis and repair of a 25 year old residential unit to get me past this heat wave, and did it faster than I think I've ever received a professional service. Ever! Which may have literally saved my life because its supposed to be 111 degrees today in Fairfield. read more

I TRIED for weeks to deal with my home warranty company re a furnace failure that left me without heat since mid-Nov. After a dear friend recommended North Bay Air Systems, I called and they immediately scheduled an appt with Ron. He provided a written estimate the same day as the appt. I also asked for and received an estimate to have a dryer vent installed. Once I ACCEPTED both estimates, I was scheduled for the following day (HOW LUCKY WAS I ???). Work was completed within 2 days last week by Anthony, Luis and Dustin. A minor electrical glitch was addressed the following day by Ryan, who went above and beyond. Every one of them were exceptionally professional, knowledgeable, neat, and friendly. I would highly recommend and use them again in a heartbeat! Carolynn read more

Ron has gone out of his way to help fix our broken A/C during a recent heat wave. He helped troubleshoot over the phone and made time to get it up and running asap. Thank Ron! read more

Ron is great! Prompt, affordable and trustworthy. I've called North Bay 3 times over the years to help me keep my 30+ year heater going and they've always done a good job. No gimmicks or shady salesmanship. read more

It's been over 5 years since I had North Bay Air Systems install a new Trane AC/Heating system in my home, but every time I have to clean the filter, I think bad things about them. Basically, I spent extra money for something I didn't get. It started out fine, and the first rep was very friendly and informative. We decided on a variable-speed system with high efficiency filters at two intakes, to provide good air cleaning to help keep the dust down in the house. But then, when the people came to do the installation, they acted like the first rep was an idiot, and they wanted to change things at the last minute, such as putting the new intake close to the 2nd intake. This would have made their job easier in installing ducts, but didn't sound like the best idea overall. The installed a new thermostat, but took away my existing almost new, expensive electronic thermostat without saying anything, and refused to return it, saying they threw it away. Then, I found out that one of the filters they installed was not at all what I paid for, but was the type you see in a stove exhaust fan, made of metal. A tech that came out later for a maintenance call mentioned that it was no good, and said he would talk to them about it, but I never heard back from them (it's been a few years now, so I don't think they will be calling). They haven't even called for any more maintenance, so I guess they avoid problems rather than solving them. Someone who came out to replace some pipes under the house told me that the AC installers had cut through part of a support under the floor, but I don't really know exactly what the details were, as I don't like going under there. I don't know if they've improved since then, but I wouldn't recommend them to anyone based on my experience. read more

These guys are the best. I've never had a bad experience from them, from the folks who answer the phone (Chris and April) to the insanely nice guys who do the work. We've been using North Bay Air ever since we moved into our place in Benicia a couple of years ago and they have handled all our HVAC needs. Our heater went out and Jose was nice enough to squeeze us into his schedule. He is the best. Super nice and totally competent. It turned out we needed to replace the entire furnace, which sucked because it was costly, but the guys at North Bay Air made it a very pleasant experience. Three guys came out and all of them were completely professional and accommodating. A really great crew of guys who do a great job. I wouldn't use anyone else. read more

North Bay Air Systems is as good as it gets! Our air conditioning unit went out and another company came our a took 5 minutes to come back with a recommendation to buy a new unit ($8000+). I called North Bay and they came right out and diagnosed the problem - a small part was all that was needed to repair the system! Then my heater unit went out - same thing - Ron at North Bay Air Systems said we had a choice of either buying a new unit or repairing the one that we have! He found the part and we are back in business! Efficient, honest, reasonable and without a doubt, the customer comes first! read more

The people on the fone are always nice and polite , the workers sent out to do the work is a different story. Had to have heater replaced and the three guys were nice and it took 8 hours to put in new heater. When city came out to inspect it did not pass because it was not connected properly. It took them weeks to have someone come out and change a cord. After they left from fixing cord ( nice guys, bit talkative) lights not working in 2 rooms, had to get and electrician out to reconnect lights. Next time sent three workers out to fix heater, wish they would speak English so I knew what they are saying about work being done in my home and one guy had bad cough and was hacking everywhere. When I asked he said it was the dust, the other guys were having problems. My property management company recommends them read more

They've done two repairs on my home -- excellent, both times. Last year, they cleaned out the furnace ducts under the house and repaired where needed, put in a new dryer vent, and cleaned out the bathroom vent. This year, they repaired the Air Conditioner. Both times fast, honest, professional -- just great -- exactly what you'd hope for. Thank you! read more

Our furnace wasn't working and after a call to North Bay Air Systems, Mike showed up several hours later and diagnosed the problem. The communication with he and the office was great and kept us informed re arrival time, etc. The next day, after a minor replacement part was installed, the furnace was up and running. Thank you! I would not hesitate contacting them if you have heating or AC needs. read more

Always great service from these guys! Jose and Jose (2 different guys) are awesome and so respectful. They explain everything well and I have always been pleased with the service for our heater units. read more

I've used North Bay at both my business and residence. They've replaced HVAC units and ductwork during a recent house remodel. I've found them to be responseive, competent and very fairly priced. Ron is great to work with. read more

It's hard to find someone you can trust to come and do work at your home. I completely trust North Bay Air Systems. We have many issues with our Air Conditioner due to our dogs and North Bay Air Systems is who I trust to come and help fix any issues. read more

Just have to tell you what wonderful service you receive for calling this company. I have never been treated so fairly and with respect to my time and condition -- today it must be 100 out and the air conditioner had a glitch. Prompt service. We love you! And wish you the best in all your endeavors. read more

North Bay Air Systems is the best! We have used them both residentially and commercially and each time, the service, response times, and prices have been right on point. Keep up the great work North Bay Air Systems!! read more

I called when my heater died and received great response, cooperation with my schedule and a competent, informative technician. Plus, the final cost was significantly lower than I had planned. Good job! read more

Terrible experience. Had a new furnace and 3 new registers installed. The furnace sounded like a freight train. Only 1 of the 3 new registers worked. Many of the ducts leaked. 5 years after the installation I found fiberglass insulation in the air return to the furnace, which had been introducing fiberglass into my home air for 5-years. I just hope none of my family suffers from a respiratory problem later in life. We recently had our entire HVAC system replaced by a qualified contractor at great expense. I DO NOT recommend North Bay Air Systems. read more

How about hooking up the wiring on a commercial air conditioning unit incorrectly? Seriously? I wouldn't recommend them to put in a ceiling fan. read more
