What Customers Say
What Bay Area homeowners and businesses say about Air Synergy
With 181 Google reviews, our commitment to quality and honest service speaks for itself.
“We recently had mini-split heat/air-conditioning installed in our Eichler home in Palo Alto by Alberto Mendez and his team at Air Synergy. They did an exceptional job! Alberto designed solutions to install units that three other bidding vendors said could not be done. During the actual installation, their work was meticulous. Every member of the crew was friendly and answered any questions that arose. At the end of each day the house was completely cleaned with no trace of their work. We would unequivocally recommend Alberto and Air Synergy to anyone planning to install a mini split system. We highly recommend them without any reservations!”
“Everyone was polite and professional. They worked non-stop to complete the installation in five days. Given that they installed the complex Harvest Thermal system, and had to remove our old heating and hot water system, it is amazing that they were able to do it in such a short time. When we had problems with the system (getting hot water in a timely fashion and operating the complex thermostat) they made two visits, added more equipment, and gave us a tutorial on the thermostat. We could not be happier with Air Synergy and are pleased that they enabled us to completely electrify our home. We would never hesitate to recommend this company to neighbors and friends.”
“Luis was fantastic! Two other providers gave opinions/estimates to repair our system, one of which recommended replacement for $90K+. Luis' solution? By far the most economical solution. And problem fixed!”
“I recently had my furnace and water heater replaced along with air ducts and a new thermostat. Alberto was very responsive, and he took the time to understand the heating issues in my house. I had a couple of meetings with him and was satisfied with his various proposals. I am satisfied with the service provided and would recommend Air Synergy.”
About Our Service Area
Local HVAC, built for San Francisco Bay Area homes
Air Synergy is proud to call Pittsburg home. From our East Bay base we deliver reliable HVAC and water-heating service across Contra Costa & Alameda counties — from Pittsburg, Antioch, Brentwood and Concord out east, to Oakland, Berkeley, and Alameda along the bay, and the hill towns of Orinda, Lafayette, and Walnut Creek in between.
The San Francisco Bay Area is really two climates in one. Inland East Bay homes run a genuine cooling season while the coast leans on the marine layer — and both sit under some of the highest power prices in the country. We size every system to your specific microclimate, not a regional average.
As a family-owned Ruud Pro Partner and Mitsubishi Diamond Elite contractor with decades of combined technician experience in the Bay Area, we specialize in luxury and architecturally unique homes — including mid-century Eichlers — where real comfort takes more than a one-size-fits-all box.
40+cities
Bay Area cities and communities served across Contra Costa & Alameda counties, all from our Pittsburg home base — with the same family-owned care on every call.

Sky-high power bills
PG&E's residential electricity runs about $0.40+ per kWh — among the highest rates in the country. A right-sized, high-efficiency system is the best way to cut what you pay. (est.)
~6-month cooling season
Inland East Bay homes run the AC from roughly May–October — far longer than the fog-cooled coast, so your system has to work harder here. (est.)
~25° hotter inland
On the same summer afternoon, inland neighborhoods can run about 25°F warmer than the coast — so the right amount of cooling changes block to block. (est.)
One tune-up a year
One yearly professional tune-up — ideally in spring, before the inland heat — keeps your system efficient and your manufacturer's warranty valid.
Bay Area comfort, answered
It depends which side of the hills you're on. Inland East Bay homes — like Pittsburg, Antioch, Brentwood and Concord — run a real cooling season of roughly May–October (about 6 months), while coastal areas lean on the marine layer and need far less air conditioning. We size equipment for your specific microclimate, not a regional average.
San Francisco Bay Area homes pay some of the highest electricity rates in the country, and PG&E residential rates have climbed sharply in recent years. Because heating and cooling are usually the largest electric loads in a home, right-sized high-efficiency equipment — especially modern heat pumps — is one of the most effective ways to keep monthly bills under control.
Near the coast, often — the fog does a lot of the cooling. But inland East Bay summers regularly climb far above the coast on the same day, so most homes here benefit from cooling. The right answer comes from a load calculation for your home and microclimate, not a one-size-fits-all rule.
At least once a year — a thorough professional tune-up, ideally in spring before the inland heat arrives. A year-round heat pump benefits from that same annual tune-up to protect efficiency and warranty coverage. Booking ahead of the May–October cooling season avoids the peak-season rush.
