SuperB! 12/24/2010

I hired Sandium to replace my 20 year old furnace, air conditioner, and ducting. The guys did a tremendous job. The were very neat and professional. The new system is quiet and heats/cools the house evenly (which was not the case the last 20years!). more

Great company for heating and cooling systems 3/12/2010

We just had a new heating and cooling system installed. Sandium was competitively priced and delivered an outstanding product. Our PGE bill dropped more then 50%! The installation is clean and we don't even notice when the system is on - while your home is comfortable at all times. Pros: best in town more

I got 7 quotes 10/14/2009

- none was as detailed and complete as Sandium's. The system was reasonable priced. The installation was great. Had a little problem after a few weeks which got fixed the same day. Thats the way to do business! more

We had a very positive experience with Sandium 8/22/2009

We had a very positive experience with Sandium. From the beginning of the bid process through the entire installation, all employees of Sandium took the time to answer our questions in a manner we could understand. In addition, the installation crew did a top notch professional job and went the extra mile on the fine details of the installation. Working with Michael and the crew head Hector was a pleasure, and I have already recommended Sandium to a co-worker. Pros: professional, clean, detailed more

""Outstanding service!"" 12/16/2008

It was 10pm and I was freezing. Called Sandium - they sent a technician within an hour. He diagnosed the problem and explained the options. I was already considering a new furnace and chose a new Trane high efficient model. They installers came out the next morning and replaced the heater. The way this company operates is really impressive. All the technicians I met were clean cut, knowledgable, friendly. I am very happy with the service received. Pros: On time, knowledgable, professional, good follow up more

Shockingly good 12/5/2008

I read other people's reviews before calling Sandium to take a look at my flaky furnace. They seemed to be well liked so I gave them a call.\r They were quick to schedule an appointment and showed up exactly on time, the even called me 1/2 and hour before the appointment so I could meet them at my house rather then the standard 4 hour wait window other vendors make you sit through. The technician was super knowledgeable and quickly fixed the problem, he even explained the whole situation to me in terms that I could understand. The cost to make the fix seemed very fair and they were very thorough in documenting everything that they did.\r I would totally call Sandium again if I have any HVAC issues and totally recommend them more

I would like to express my appreciation for a job exceptionally well done 3/26/2008

Sandium recently replaced my furnace, air conditioner, and ductwork. \r \r I would like to express my appreciation for a job exceptionally well done. The estimate was detailed and fair, the work was efficient and on time, the advice was factual and professional. The expertise, especially providing a detailed load calculation, duct design for the project, and the professional integrity are impeccable.\r \r It is not normally my habit to write such reviews, as I expect that jobs I contract for are well done. This case, however, deserves special recognition.\r more

""A great company!"" 2/13/2008

A great company! My furnace broke. They had someone out within 1h. The service man was very knowledgeable and courteous (he even put shoe covers on to protect my carpet!). He found the problem rather quickly and fixed it. The next day I received a call from the service manager to check if I my furnace is working properly and if I am happy with the service provided. And YES I am. I will definitely use Sandium again. more

Problem was diagnosed quickly 2/8/2008

""Quick initial response. Problem was diagnosed quickly. Replacement part arrived and installed in a timely manner. Very good follow-up as well. I will use Sandium again in the future. Thanks."" more

I was surprised how fast and effective there technician was 1/30/2008

Sandium came to my house to troubleshoot a wine cooler. I was surprised how fast and effective there technician was. He found that the controller was bad. I was surprised again when he told me the repairs would be more than a new unit. In the past the technician always want to do the whole repair and charge a lot for it. But Sandium told me it would be more cost effective to buy a new one and explained how i could install it myself. They were very honest. and Finally he did not charge me for the temporary repairs to my cooler to save my wine collection. Thank you Sandium! more

""Sandium is the best contractor I ever did business with"" 1/24/2008

""Sandium is the best contractor I ever did business with. I did numerous home improvement projects over the last years. I always selected very good, reputable companies. Sandium stood out from that pool of excellent service providers. The quality of work was great and the level of service outstanding. Sandium provided a great combination of craftsmanship, product knowledge and professionalism. I will definitely recommend them to family and friends."" more

""The guys at Sandium were very professional.."" 1/21/2008

""The guys at Sandium were very professional, did a great job and kept me informed every step of the way. They were very up front about the pricing and were quite competitive compared with our other 3 offers. I would definitely recommend Sandium."" more

I've got to tell you, you saved our Christmas! 1/17/2008

I've got to tell you, you saved our Christmas! Me and my family are very greatful to you and Sandium. I called your company on the morning of 12/24, as my furnace wasn't working. I thought that we would have to go to find warmth at a friend's house for Christmas, how can you expect to get a new furnace installed on the day before Christmas? I was afraid that I would have to spend $2K for a new furnace, and probably any other company would have made me buy a new furnace. Not Sandium, though, you guys are honest and straightforward. Your technician, Jacob came out and was able to fix the furnace, though it took him almost two hours, it really wasn't easy. Jacob is a very experienced and professional technician. Again, I was ready to pay for a new furnace, but you saved me the expense this time. \r I'll definitely have you guys replace my furnace in a few months, and thank you again!\r Mac I.\r more

""Excellent Job !!!"" 1/15/2008

""Excellent Job !!!: I wanted to repair my old duct work and was also looking into replacing furnace and A/C.. I started with four quotes. Three were very short - Sandium's very detailed. At the initial consultation I was told that I am buying a finished product (equipment and professional design/installation) and not just some pieces of equipment. At the time I was confused what the estimator was talking about but when they started the work I quickly understood. A team of three excellent professionals worked diligently for several days. The final product: A great comfort system. Even the inspector was impressed! I highly recommend Sandium!"" Pros: They kept my house really clean. more

Highly recommend. Polite, knowledgable, customer oriented! 1/10/2008

I am very pleased with Sandium. My heater broke. A service man was at my home within 1h of my call. I was told by another contractor that I needed to replace my furnace. Sandium's tech fixed the problem. Instead of paying 2k for a new furnace I paid $130 for the repair. Thank you Sandium for a job well done. Pros: Excellent communication. I appreciated the follow up call from the office more

Outstanding! - In every aspect! 1/4/2008

What a great experience! Courteous, knowledgable, clean, on-time, detail oriented - I can go on and on. I normally don't take the time to write reviews but these guys are worth mentioning. Sandium is my kind of company! Pros: Great value, excellent workmanship more

Best contractor I ever worked with 12/23/2007

I had my new heating and cooling system installed by Sandium. I am very happy with the result. We worked with several contractors over the years - not one was even close to the level of professionalism, quality and service Sandium offers. I highly recommend doing business with Sanidum. more

One of the few which make 1 + 1 = 3 8/10/2007

We were very satisfied with every aspect of the project. Very professional, very detail oriented, very friendly and knowledgable. We strongly recommend Sandium. Pros: Great company to do business with more
