Why Sandium is a different kind of HVAC contractor

Every contractor says “we are different”… Let us explain why we really are …

We are here for YOU

One of Sandium’s management staff is responsible for your project. We will be there to get your job started, and we will be there for you if there are any questions along the way.

NATE Certification is your assurance to Technical Expertise

Our lead technicians are NATE certified.  This means that our technical staff are tested, trained,  and certified to be among the best professional technician in North America.  Read about NATE.

We offer a complete, customized Whole-House approach

Our whole-house approach makes us a different kind of contractor.  When you schedule a home consultation, you will get an honest, custom appraisal of your needs. Every home and  every homeowner has different needs and requirements.  We don’t offer a “cookie cutter”, one-size-fits-all solution. Only after we visit your home to get to know you and get a feel for you home, do we sit down an develop a custom proposal for you.

Satisfied clients our our No. 1 source of new business

The majority of our work comes from client referrals, from people just like you.  We want you to be 100% satisfied.  If so you refer us to your friends and family members.

Our customers are our treasures. 

We offer long-term maintenance agreements and 24×7 access to an on-call staff person who will be ready to assist you.
