It made me very happy to hear that our 10 year old furnace and AC are still in perfect shape. He did pitch an optional bypass unit to us; while he was very nice about it and made sure to mention it wasn't mandatory, it felt a little unnecessary since everything is already working so well. Still, Billy's customer service was excellent and the quality of his inspection was top notch!

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! Furnace now runs like a dream, keeping our home comfortable, with balanced heat between rooms and just as important, significantly quieter operation. We nearly forget it is running. Fantastic.

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

They offered partial refund and service to show that they want to fix the wrong and prove that they are a great service company. ------ Original review: I had a very negative experience with air shark technician. My issue was needing the capacitor replaced. The fix was quick and I was clearly over charged. When I asked about this, the technician just said it's just business. He exaggerated the price of the part needed which is a capacitor saying it's like $200-$300. It's at most $50. It took him like 10 minutes to replace the part and said you either accept the charge and pay or I just take it out. It felt very predatory, like I already fixed it you might as well pay. He proceeds to measure temps and other various things just to pass time while he waits for me to decide if I want to pay or have him unfix it. I can accept being over charged but something about how this situation transpired left a bad taste for me. For example, why wouldn't you say you need to replace this and it cost this much for the fix instead of fixing it first then say pay or I take it off.

The quoting process was straightforward -- no pressure, no mystery line items, and they actually explained the equipment options instead of just pushing the most expensive thing.

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

Turns out, Jazz not only fixed a huge backup of sewage, fixing the immediate issue; they did it with such professionalism that I was really impressed. Monty and Isaiah were a great team. Special shout out to their non-pushy approach. I really appreciated the speed, efficiency, professionalism and honesty that these associates demonstrated. The folks on the phone, such as Mario and Adrian/AJ, are also fantastic and really made the process easy end-to-end. Well done, Jazz. That was excellent overall value and the highest-quality service I could ever ask for.
