This is the fourth HVAC company we have had come out to take a look and they were the only ones to be able to truly figure out the problem. Eli was able to quickly diagnose the issue, Jason was very communicative and friendly and made sure that we got text updates and phone calls for every appointment. We needed a whole new system due to an evaporator coil manufacture defect issue and they gave us several options to choose from in order to accommodate our budget. Chris and Paris came out to install our new system and they worked quickly, were able to get our new air-conditioning unit and evaporator coil installed in less than a day, and they did great work; it has been running amazing ever since. Jason made sure to get us a system that could accommodate the size of our Home as the one that came with the house was too small for the size of our house. I cannot say enough great things about this team, I very highly recommend calling them for your HVAC needs!

Thank you so much for the quick service and for your good advice. It was definitely worth the $165 diagnostic fee.

It made me very happy to hear that our 10 year old furnace and AC are still in perfect shape.

Matt, the owner, answered the phone immediately and took excellent care of us from the very beginning. He was responsive, professional, and made sure we understood our options. Romell was the technician who came out the following day. He thoroughly evaluated our system and determined that our AC was no longer working. Later that same day, Matt came out personally, went over everything with us, and explained the options and costs for replacing our system, including both a new AC and heater. Within just three days, Cesar and Jesse came out and professionally installed our new heating and AC system. They were efficient, courteous, and extremely respectful of our home. They completed the installation in a timely manner and, incredibly, left our house cleaner than when they started! A huge thank-you to Matt, Romeo, Cesar, and Jesse and Jackie for making what could have been a stressful situation such a smooth and positive experience. Their professionalism, responsiveness, and quality of work really stood out. I would absolutely recommend Prime Air to anyone who needs HVAC service or a new heating and AC system. Five stars all the way!

I had shopped around and found them to be very competitive and they had a solid reputation. The unit has been working flawlessly ever since the installation but though it was time for a maintenance/checkup. I called for an appointment and was quoted $95 for a checkup... I thought that was reasonable considering it had been over 5 years since the installation. The owner, Barsin stopped by and did a thorough inspection, checked the refrigerant, condenser, inspected the main unit, filter etc. all was well which I suspected but just wanted to be sure. He even popped his head into the attic to look at some of the duct work which is the original to the house but still functioning. When he completed the inspection I asked him how he would prefer to be paid and he said "No Charge", everything is working as it should so you are go to go... I thought that was pretty swell:). Anyway, just thought I would pass along a very good HVAC service/ company in the South bay for those looking for a competitive price, quality products and great service... Even after sale service!

Both Nahira and Rolando handled the removal of the old unit and the installation of the new one smoothly. After the job was done, they clearly explained how to use and maintain the new system.

Our older unit was too big and pushed heat/air-co through the home with too much force and was far too loud. They knew exactly how to resolve the problem, and within a day, they had a new unit on order and began the work in a few more after that. Install team were tidy, did quality work, and were very helpful. Nice and friendly, too. 24 hours after install, it was clear something was wrong with the new furnace. Angel had his tech George out the very next day he and diagnosed the problem quickly. The new part arrived the next day and it was installed that morning. Very responsive and professional!

Jr's service was recommended to us on a very short notice and he was able to make it the same day after hour. He was super on time and had great communication letting us now when he was on the way. We have worked with several AC companies, many high review ones you see on the internet in bay area region. The quality of the work Jr delivered and high volume of cool air coming from AC reminded me today to come and write this review. We expected just a consultation but he had the parts on spot and changed the burned unit right in the first 10 minute of showing up. This is not what you expect usually from AC guys, they quote you for some parts that are not even broken and delay is the tactic. He even washed the filter of our AC recommended changing its type, and even when we asked about protecting our AC from rodent he provided the taping on the piping to reduce chance of damage. There were so many things that were addressed in a short 30 minute visit that need three other AC ppl to address it if we called other companies. Above all he was beyond fair, the quality of his work with the value and price he offers is unmatched. Trust this guy, he is a good family man that fixes your AC promptly with no gimmick.

I got a quote shortly after which was competitive with the others received. Aside from price, what sold me was the confidence and expertise I felt from talking with Pablo. He called out a few safety concerns that other HVAC technicians did not and that ultimately helped me make the right call. Once I accepted the quote, Pablo ordered the equipment and came by the next day with his crew to start the installation process. After an aggregate of three days in a week's span, the job was completed. Later on when I needed Pablo to assist me in permitting and inspections, he helped me without hesitation and made sure everything was wrapped up with the city inspectors. He's a man of integrity and honest work that will get the job done and support you end-to-end. Would recommend Pablo to anyone looking for HVAC or mini split needs. He has your back and you want him on your team. 5/5

Anyone who's done a permitted HVAC job knows the paperwork is where contractors go quiet. Not here.
