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!).

Great company for heating and cooling systems

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.

I got 7 quotes

- 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!

We had a very positive experience with Sandium

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.

""Outstanding service!""

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.

Shockingly good

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.
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.
I would totally call Sandium again if I have any HVAC issues and totally recommend them

I would like to express my appreciation for a job exceptionally well done

Sandium recently replaced my furnace, air conditioner, and ductwork.

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.

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.

""A great company!""

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.

Problem was diagnosed quickly

""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.""

I was surprised how fast and effective there technician was

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!
