Sandium Heating and Air

We hired a top rated Engineering firm to design our HVAC system with mini-​split systems and radiant heat. After we received the building permits and started framing the house, we called in a couple of top notch AC firms to bid the job, only to find out the plans we had paid for were impossible to implement. Nik at Sandium made several visits and worked with us to find a solution to what seemed at first like an impossible installation. I am very happy to say that we came up with a very good plan and the units have been installed successfully. On top of it, we saved a significant amount of money by using a different design, but still have the same great system and energy efficiency. I am on site almost every day and all of their workers have been polite, hardworking, and professional. I am very please with our experience with Sandium and highly recommend them.

Michael didn’t take our situation and plug in his solution.
He took our situation and sculpted a solution to best meet our needs.
We wanted to install air conditioning. We got quotes from 4 suppliers, and selected Sandium because Michael listened to our needs and then put together a solution that met them.
He provided us with alternatives, their costs and benefits, and then let us decide.
The installation crew were very efficient, courteous, and clean. Hymay in particular displayed expertise in a broad range of skills.
Now we can’t wait for July to see how this air conditioning system really works!

Info: I had the following installed: Furnace, A/​C, ducting and whole house fan.
Very professional experience from beginning to end. Tyler is helpful, informative and made me feel comfortable through the entire experience. He answered all my questions and worked with me to get exactly what I wanted.
Final verdict: The system works better than expected, quality of the work is excellent (passed inspection easily) and the staff was a pleasure to work with

Top notch heating contractor and the best in the south bay area.

We used Sandium to replace all our duct work under our newly purchased house. They were great! They showed up on time; did excellent work; and cleaned up their mess. They even played with my pug. Huge thumbs up. I will gladly work with them when I replace our old heater and AC in the Spring.

I made an appointment on a Friday for an estimate. The estimator called back in an hour and made an appointment for next Tuesday. He was on time and gave me a great estimate for a new furnace. He scheduled the installation for the next Monday. The crew was on time and did a great job installing. Before they left, they carefully cleaned after themselves. Great experience!

I was referred to this company by a sales rep for heating and AC components. He said they were very good and I could trust them. I had the exact opposite experience! Their sales/​estimate guy Tyler is an absolute mess! He breaks appointments, gives time lines he can’t keep, and strings you along. What was supposed to be an estimate that he said would take 2 days to send has taken a week and still no estimate! Called him multiple times and always has a excuse. Never lived up to what he promised to do. I would be aware of dealing with this company. I called and talked to Mike the owner and he did seem very nice and wanted to try and help, I just had such a bad experience with Tyler I was not going to use them not matter what.
Update: Tyler sent an email to me explaining all of the confusion on his end… upgrade to two stars for at least taking responsibility for dropping the ball.

I know it’s been awhile, but I never got a chance to provide an additional follow-​up to this string. Michael Lee, one of the executives at Sandium, reached out to me personally a few months after the events with Sandium transpired. We were able to meet in person and talk about my experience.
He expressed his concern regarding some of my issues, and I came away from our talk knowing that he took the matter seriously and was to address the concerns accordingly. I appreciated him taking the time to meet with me, and just knowing his passion and care regarding his company impressed me helped me restore some faith towards their service.

I am not sure what I can say about Sandium. They have been fantastic. This is the second house and 4^th project they have done for me and always excellent. This most recent project has been– a bit more difficult then most– and I will update on it when its fully done, but they have been stellar and have gone above and beyond the call of duty to handle it. The difficulty for this project is nothing to do with them but with another company as this work spans multiple companies. I will update fully when the project is done, but I wanted to give them their stellar review now.
Be sure to ask for Tyler. He is awesome.

Cann’t really say enough good things about Sandium. I had my HVAC replaced by Sandium in 2009. No issues since then. Had a recent problem with my AC. Sandium came out and had to work with Carrier since it was under warranty to diagnose and remedy the problem, Sandium had to come out 4 times to rectify the issue working with Carrier. While it took longer than I would have liked, the service, professionalism and follow-​up was outstanding! I called my sales rep Nik who sold us the unit in 2009 and it got resolved promptly. I am a customer for life! Usually most places sell the original unit and after service is not great. Sandium is in a class by itself! Next time I need a HVAC or someone needs a HVAC, I will be recommending and endorsing Sandium with high praise!
I wish my other service vendors like Plumbers etc. were as good as Sandium. Hope…

For replacing my HVAC system, I got 5 bids. Two of them just estimated the size of the units based on square footage, one of them did detailed calculations on the size of the set up needed but none of them talked about PG&E rebate for energy efficiency. Michael Lee was recommended by another friend who used Sandium and he was very happy with the work they did. So I asked Michael Lee to give me a quote. He recommended Carrier Heater and AC units, replaced ducts and added attic insulation and we are getting $ 3100 rebates from PG&E and $ 1250 rebate from Carrier. He also recommended a much smaller size heater 60 000 btu than 100 000 btu heater. Hector and his crew did the installation and we are very happy with their professionalism, every day cleaning and overall quality of work they have done.
We recommend Sandium highly.

I’ve hired Sandium to relocate the AC unit! Their technicians were on time, on schedule, clean and very polite! I am impressed and would recommend to everyone I know!

I can’t say enough good things about these guys. One of the most professional, knowledgable, and courteous contractors I’ve ever worked with. Installation was done on time, clean, and never had a problem for ~5 years. What impressed me the most is that Nik remembered me after all these years, and he went out of his way to help me with a bit of situation I have with my remodeling contractors regarding the HVAC system. It is very comforting when you have someone you can trust on things like HVAC, auto repair, etc. I can count on these guys.

We needed to replace a 45+ year old furnace and non-​functioning air conditioner. We were pursuing rebates through the Energy Upgrade California Program, who provides a list of contractors participating in the program. My wife and I received four bids. Our experience in the bid process ranged from horrible (can’t believe we let that guy in the house) to excellent (hope they give a reasonable price because we would like to work with them). We were fortunate that the excellent was Sandium.
Sandium really stood out from the rest the moment they came to the house. Our estimator, Tyler Lewis, was knowledgeable, provided the most thorough estimate and was just generally a great guy. He listened to our needs and translated that into a system that fit our needs and our budget. He did not try to up-​sell, add additional projects, or pressure us in any way. He went into the attic, looked at the electrical panel, water heater and existing gas lines and took thermal readings of the walls to get a sense of our home energy challenges. Finally, he provided an itemized WRITTEN estimate that identified each project component and the cost for each thing. This was one of the main decision points for us as the other estimators would give a general estimate with few to no specifics. Also, Sandium provided the lowest bid and even negotiated a little to fit our budget.
Shortly after signing our contract we scheduled the work to be completed. We had some challenges, like removing asbestos ducting, that Sandium was able to accommodate. The work involved moving the furnace into the attic, from a hall closet. relocating the AC, replacing the gas line, running dedicated electric and putting in insulation. We couldn’t be happier with the team Tyler put together to help us. Jesus (Chava), the team lead, was really a skilled installer and took great care in managing the work. He went above and beyond to finish the job and provided thoughtful guidance about how to operate our new system.
The work took a week to complete. They were able to work around obstacles like pets and toddlers. They contained their mess and always cleaned up after themselves. All inspections passed the first time. Sandium submitted all paperwork necessary to receive our EUC rebate ($ 3600 for the project). We now have a comfortable, more energy efficient system just in time for summer.
To all interested, I would highly recommend Sandium. Beginning with Tyler Lewis as their Representative, to their installers, Chava and crew, they did quality work for a very reasonable price. I respect their professionalism and attention to detail. I know my family and I appreciate the job well done!

We had a dinosaur era heater in our 1930’s home that we wanted to replace with a HVAC system complete with medical grade air filtration unit. Sandium came highly recommended and they didn’t disappoint. Their quote was in the running with 2 others. They arrived as scheduled, kept to the agreed timeline and were the cleanest, most conscientious team we have ever seen. They listened to our concerns regarding duct placement and made adjustments to provide the maximum amount of access to our under house storage while keeping the air flow efficient.
We highly recommend them to anyone replacing their HVAC system. They are one of the most professional implementation teams we have ever used. Good work guys!
Thank you!

Nick did a really outstanding job on my 3 bedroom, 2 bath house in menlo park. He stalled heating, air conditioning, ducting, and a NEST 2.0 thermostat. Everything works perfectly, passed the HERS testing with flying colors, and is so quiet. The house is so comfortable now. 5 stars and would definitely recommend.

Our house was always too hot upstairs and too cold downstairs (heat goes up) because we had a single zone AC/​furnace system. I asked other companies how to solve the problem. One just said to close the upstairs vents, which I had tried but could still hear the air pressure pushing at it all night. Another said it was too difficult in such a small house. However, Sandium came up with a great 2-​zone system for a reasonable price. Downstairs and upstairs can now be set to the exact temperatures we want. Thanks so much Sandium. They also did a great job fixing leaks in the attic duct work.

Have had these guys come out in the years since installation for cleanups/​updates. I’m lazy like that. Nothing as above and beyond the installation experience; sometimes the guys are a little reticent and they sort of go out there, check a couple of things, and at my insistence, they come inside and check on the thermostat. But no one ever goes up to the attic to look at anything any more and they’re sorta in and out of there. Pricing for that is $ 85, FYI.

We moved into an old home. The furnace and air conditioning system had to be overhauled completely, as the house was built in 1965.
I used Unilocal and called 3 heating/​airconditioning companies with the highest Unilocal ratings and chose Sandium.
Nik, knows so much about heating and air conditioning and keeps up with the latest trends. I think he actually has a degree in physics but is quite shy about it. He was the only company of the 3, that knew about the energy rebate that was available. He came and tested our air quality before putting in the new heating/​aircon (and new ductwork) and then came afterwards and did the test again. The improvement was so drastic, that we are getting back a couple thousand for upgrading our system.
We also have horrible allergies and all see an allergist. Nik made sure that he installed a special medical filter in the attic and all air goes through it. The system has been flawless.
Since I bought the furnace and ducts from them, my service is free for 3 years. They are never late with an appointment, they have the BEST and most honest service people who come.
They were not the cheapest, but their units and service is well worth the piece of mind. They have since come back and installed another unit in my home for an addition. I then recommended them to friends who were doing an addition and those friends are thrilled!
I wish all the contractors that work on my house were like Sandium!

Sigh. Time to replace the furnace and AC. Sigh again.
Do you ever wonder if any company really cares about the work they do without question? Do you ever wonder if someone is going to actually follow up with you before during and after the work they’ve done? Did you ever wonder why it’s so hard to find a company that will design with your needs in mind and not take shortcuts? Do you ever wonder why they never seem to show up on time, leave your house a complete disaster or quote you one thing and charge another?
Don’t wonder anymore. Sandium performed 5+ stars across the board.
Tyler, who initially came out to quote the job, did far more than a cursory look around. He didn’t jot down some number that seemed too low for the job we needed done, as the six other companies we invited to give us a quote. Tyler spent over an hour with us, actually went up in the attic to look and see what the heck was going on, then sat down and LISTENED TO US prior to providing us SOUND advice — he’s got a ton of expertise in environmental consults and clearly knew what we were experiencing.
While the quote was 2x of the three out of the other six who actually decided to send us a quote, it was because our job was not an easy one. We opted for a Carrier system — and Tyler was not intent on pitching the most expensive system but the units that met (and exceeded) our needs.
Hector and the crew are extremely continuous: neat, clean, efficient, on time, on task. They never made me feel intruded upon in any way at all. I played music while they were here for them and each day they thanked me for it — cool guys.
Our house went from sounding like we lived at the airport under construction on a hot day to a cool, efficient, quiet, comfortable place. Our bedroom is not a breeding ground for dust bunnies nor can you cook an egg on the floor when the sun is coming in our window anymore. THANK YOU Sandium. AND DO NOT HESITATE to ask for a reference. We love these guys.
