The owner Michael personally came out to review our project and provided excellent recommendations. Everyone at Sandium was extremely professional, courteous, and responsive. Eric and his assistant who were assigned to perform our installation were awesome and did a fantastic job going above & beyond our expectations! We've already recommended Michael's company to fellow associates.

The guy from Sandium Inc. came to our home, though it was very late for him (8:00pm) and fixed the issue. Also, suggested that for future what could potentially could happen with the heater. I would strongly recommend Sandium to other users of Service Magic

Nick is really helpful. He tried hard to make customer convenient. He came to my home for estimation at 9pm, replied my email at 6am... He's very knowledgeable, not only educated us about furnace, also gave us suggestion how to insulate our 50 years of house. The best I like him is he never suggests extra spending, if he thinks the result of adding one thing is marginal, he lets you know, not sells to you for no good reason. The installation is also went very smooth, very clean. Their price is also very competitive. highly recommend.

Michael called me within minutes of recieving my request. The tech (Jake) that came out was helpful, knowledgeable and took the time to explain everything he was doing to me. If I need to upgrade my heat pump later this summer, I will definitely call them again.

This company called me on a Sunday to set up the appointment. We were delighted that they did that. They came out the very next day and got the work done. They did an excellent job.

Everyone I spoke with in this company have been very straight forward giving unfailing information that I could understand. They showed concern, patience, and honesty in their communication and work performed. Price was very reasonable and well earned. It is hard to find service and customer satisfaction like this these days.
