Company Overview

In 1948, we launched Superior Mechanical Services, Inc. as a family-owned business. The company transitioned in 2005 when long-time employees Jerry Williams and Joe Enos acquired it to uphold Superior's legacy as a top-notch mechanical contractor. We operate as a union shop, the majority of our technicians and staff have extensive tenure with us. We take pride in our craftsmanship and strive to deliver value-driven service with a straightforward approach.

Since 2000, Jerry has been involved with Superior Mechanical Services, Inc. He grew up immersed in the mechanical trades, as the child of a plumbing and heating contractor, having finished a union apprenticeship in plumbing and pipefitting. Jerry is a CPA and obtained his bachelor's degree in accounting from Temple University as well as an MBA in taxation from Cal State Hayward.

YES - This One - Complete Furnace and AC Replacement - Top of the line Goodman products - Took a lot of research to find a Trustworthy, Best Price by far, Goes over Above service expectations Company....

Dano who quoted, George and his Install Crew. You Guys Rock !

Seriously- Save Money while dealing with a Great Company. I have almost a religious fervor here with this recommendation. No BS.

Hard pass.

Had them do a diagnostic for $99 on HVAC system since a/c wasn't working for. They did come on time and all while letting us know the issues. However, the quote they provided to fix the issue was insane. I was very skeptical that the repairs cost even close to that much so I went and got a 2nd opinion...which ended up being less than a 1/3 of what Superior quoted. I don't want to go into too much details but I always recommend getting a 2nd opinion. What Superior quoted was not even close to market rate, it was way inflated.

I've been a happy client since 2017! Something that really impressed me right off - they always answer the phone during business hours, unlike a lot of companies where you just get voicemail, which is the worst when you have an emergency and have to wait for a call back.

When I moved into my new home, my HVAC needed attention, so it was a relief to be able to get a real person on the phone right away.

Superior helped me with repairs and upgrades, and their service reps are professional, on time, and always courteous. They go out of their way to explain exactly what they are doing so I understand.

In 2018 I started taking advantage of their customer care plan. I pay $14.95/month. Here's what it covers - In the winter, they come out to service my furnace, and in the spring, my AC. They replace filters and make sure everything is working properly. More important, I get priority with urgent issues since I'm a VIP client.

I have referred Superior to my friends many times, from service and repairs to AC unit replacement, and they are all very happy!

I highly recommend Superior has been around since 1957 and they are THE Bay Area experts!

Superior is amazing and on the ball! I wanted to see if I could make my heating more efficient. They scheduled me easily, the technician was prompt, friendly, and informative.

Even though they're in Livermore, I've had Dano at Superior come to Oakland to replace several wall gravity heaters as well as a forced air unit. It's never been a problem to schedule. They've also installed dryer duct booster fans (Tjernlund). Price is always very competitive, they pull permits and are consistently communicative. I highly recommend you give them a shot.

I would call someone else. They installed new AC for me and subsequently got busted for working without a permit. Then they billed me for maintenance when they never showed up. After a couple heated phone calls they got the message and fired themselves. Good riddance!

After moving into our house, we quickly realized that our heating system worked very poorly in many parts of our house, with little to no airflow. It became apparent to use that we needed a full update and revamp of our system. The job called for replacing basically all of our ductwork, installing air conditioning, replacing an old furnace, and putting in a three zone system to allow for greater efficiency.

We got several bids for the job, and despite the fact that Superior was located in Livermore (and we're in Redwood City), we went with them as they had done work for my family before and gave a very competitive estimate and timeline. They handled the permitting, Title 24 process, the inspections, and we were happy with our ability to communicate with them. The work itself took 5 full days, and they did a good job cleaning up, treated our house with care, and generally gave us a positive experience. With the heat we've experienced lately, having a well functioning HVAC system is a great investment and a real lifesaver.

Would highly recommend Superior Mechanical!

Last week I had a brand new water heater installed by superior mechanical services out of Livermore, CA. This company was very efficient and did an exceptional job with the new installation. My new water heater passed inspection & The installer was very kind, efficient and very easy to talk to. Nothing in my garage was disturbed, no mess was left. I would highly recommend this company for any other needs. Thank you again to Milton.
