Short Story: These guys are awesome. Showed up as they said they would. Diagnosed the issue with my…read morefurnace and came back the next day to repair it at the price they quoted. No BS, just an honest helpful team. Long Story: I got home late on a Tuesday from a business trip to have my wife tell me our heater isn't working. I spend an hour or two messing with it with no luck. I pull out the one space heater we have and put it in my 10 month old daughters room. Christmas Day is Saturday and it's been rainy and colder then usual all week. I start calling around early Wednesday morning. I call anyone that seems like they have a website and a storefront if someone sort. Most tell me they are booked out till January. Earliest appointment I can get is Dec 27th. One guy warns me to be careful because the "reputable" companies are all crazy busy that people are getting scammed with high prices and shoddy work. Now I'm starting to feel a bit more desperate so I call anyone that seems to have decent reviews. I come across SF Bay Air on yelp. Can't find a google listing, a website or an address for them but they seem to be very close. I call, no one answers and I leave a voicemail. Nabil calls back an hour or two later and says it's a crazy day but he will find a way to get out to take a look by the end of the day.Can't promise a time or even a rough window but they will be there. I ask him about cost and he tells me it's $125 to come out and diagnose the issue. Late that afternoon Ali from his team calls me to say he's on his way. He shows up and within an hour is able to find that a motor is acting up. He tells me he can get the part in the morning and then come install it for $800 all in. He also said we would only charge me The $125 if I wanted to order the part and install the part myself. I tell him to go ahead. Again no promises on when they would arrive but he ends up back at 10AM the next day gets the part swapped and everything working. Makes sure to have me test turning the thermostat on and off to make sure all is good. Ali even mentioned he saw the diapers form my daughter in the basement so he knew he needed to get this fixed ASAP. Nice to know someone cares these days. Would highly recommend to anyone.

He's the only…read moreHVAC contractor I know who does proper heat load calculations for the home to size the system correctly. Many companies will over size a system and the client will never be the wiser; only knowing that the heater/AC works, but not that energy and money is being wasted.

His prices are quite reasonable, especially knowing you are receiving the highest quality workmanship.

From start to finish, the team was professional, experienced and helpful. They were so respectful of my home, and I really appreciated their attention to keeping the space clean along the way. I am very satisfied with the result. I would highly recommend Rivera's Heating and Air Conditioning to anyone! Thank you Marcos and Team!

Elliott Air Systems did a phenomenal job with the installation of a new Carrier heat pump system in…read moreour home. They carefully removed the 80 year old gas furnace from the crawl space and patched all holes. They installed the air handler in the attic and carefully cut in all new vents in the ceiling. Duct runs in the tight attic space are installed with the highest level of care and craftsmanship. They were extremely diligent about managing dust and mess; the only sign that they had been in the house were the new vents in the ceiling. As an architect, I have the opportunity to work with a lot of different contractors. Based on the great experience I had working with them in my home, I highly recommend Elliot Air Systems to all of my clients. Great value, phenomenal work; EAS earned my highest recommendation.

This thing is like a rocket ship compared to our old heater and the guys busted their butts to get it right. From the start Alberto was super accommodating, straight forward, honest and nice. He's just a really nice guy! He took the time to listen to my objectives and had great recommendations for the right system that would work for our goals, our home and our budget. Once the proposal was approved, communication was good about calendaring and as the install date drew nearer they had all the equipment and hardware delivered to the house. No delays on account of supply chain issues, yay! Jorge and the installation team showed up when they said they would. They were pleasant to have around and communicated very well. Not only did they fearlessly crawl around in my basement and crawl space, they took the time to try and run the ducting in the cleanest way that would take up the fewest cubic feet of our precious's storage. Totally impressed. Good work!

TL;DR, If you are interested in getting a heat pump for heating and cooling and happen to live in…read moreVayu's service area, you should definitely hit up Shreyas. He solves for each home individually with technical rigor and a keen sense of pragmatism, maximizing both comfort and value-for-money and leaving you (the customer) with a solid grasp of the sticky issues around HVAC. Great choice if you want to 1) modernize your heating and cooling 2) install quality equipment without overpaying 3) collect some nice rebates 4) deal with minimal hassle 5) decarbonize your home. I had a terrific experience working with Shreyas and his team at Vayu to replace my existing A/C and furnace with a new heat pump for our central ducted setup. I was floored by his technical expertise and relentless focus on customer value, ultimately leaving us with an excellent deal on a properly sized installation as well as a wealth of insight on heating and cooling our home properly. I came across Vayu by way of their excellent blog and podcast, where I incidentally learned quite a bit about both the pros and complications of going electric for heating and cooling in California. Shreyas conducted several different analyses to determine the required load and ideal equipment, incorporating our historical energy bills as well as our current comfort level during summer and winter. Since we had already spent quite a bit on home upgrades this season, he also recommended a value-priced brand which offered the same benefits as (or rather happens to be physically identical to) premium-branded hardware. Paperwork and installation were a breeze. Vayu's subcontractor Tommy was swift and professional, leaving a clean install with no mess. Shreyas quickly took care of permits, rebates, and applying for the $10k interest-free loan through Peninsula Clean Energy, while dispensing pages upon pages of bespoke advice over email. He really went above and beyond to ensure that we got the best heat pump solution within our parameters, rather than trying to upsell us on fancy equipment or extra services. The only complication arose when the system failed the 3rd party HERS test, meaning the previously existing ducts were found to be very leaky. Although the problems were not of Vayu's making, the team worked with the testing company to make the necessary mitigations to clear the install for final inspection. Shreyas also helped me come up with an action plan to improve the leaky ductwork situation in the future, rather than pushing through expensive repair work in the short term. We're now well into a chilly December and I'm pretty confident in saying that our heat pump system is an upgrade on the previous A/C + furnace setup. It does a better job in terms of steadily keeping our home warm (cool), rather than sending blasts of hot air out of the registers and producing big swings in perceived room temperature. Basically, we're less aware of the HVAC system battling the elements to the point where it's hard to know when it's particularly cold/hot outdoors. Energy electricity costs seem more or less in line with what we had been spending on gas previously.

From the very beginning, it was clear that Shreyas is not just a highly skilled professional, but someone who genuinely puts his customers' best interests first. He stands with his customer. Instead of just selling me a standard package, he spent a significant amount of time understanding my specific needs to find the most efficient and cost-effective solution as well as the incentives I could get. His expertise is evident, but what truly sets him apart is his dedication. A few highlights of my experience: True Professionalism: The HVAC installation was flawless, and the attention to detail was impressive. Going Above and Beyond: When I ran into major issues with a separate water heater contractor, Shreyas didn't hesitate to step in. He helped me troubleshoot the situation and provided expert advice as if it were his own project. Incentive & Rebate Expert: He proactively helped me re-plan and navigate the complex incentive application process to ensure I maximized my savings. It is rare to find a contractor who is this reliable, transparent, and genuinely helpful. If you are looking for an HVAC company that you can trust 100%, look no further than Shreyas at Vayu.
