I was able to easily schedule them. They came out and serviced my air conditioning and heating unit for my home. They explained everything that they did very thoroughly explained how to bring everything up to the latest code and the pros and cons of those improvements if I chose them moving forward, and my service technician was very professional and kind. He was very easy to talk to. I would recommend them hands-down, no reservations.

Worked with Noe today from Sandium. Just have to say a big thank you again. I’m a first time homeowner learning about my homes HVAC system. I found Noe to be patient and thoughtful as he took time to give thorough explanations regarding our home heating system. He was able to diagnose potential hazards and provide feedback. I felt taken care of without any hassle or pressure. I will be hiring Sandium 🙂

Christopher did my maintenance and I could not be any happier. He is professional, courteous, efficient, on time and very respectful of my home. My system had a few technical difficulties; Christopher worked through the problems methodically and never rushed and solved the issues. In addition to his professionalism he is an absolute pleasure to talk with.

Very professional! Installed central air and heating into my home for a reasonable price. Obviously, an expert in their field. Responded promptly to a few warranty repairs and resolved them quickly.
