D. Silvestri Sons, Inc.

Why Choose A Certified Contractor?

 You can count on D.Silvestri Sons to do your diagnostic and repair work efficiently because our technicians are NCI (National Comfort Institute) certified.

Why chose a NCI certified contractor?
For the same reasons most of us choose:

• A certified public accountant to do our taxes
• A certified realtor to sell our houses
• An AMA-certified doctor to examine and treat us
• A bar-certified lawyer to represent us in court

In all of these professions, the designations come to people who have studied, tested and achieved a level of competence that resulted in receiving a professional designation.

As an NCI certified contractor in air diagnostics and balancing, or certified in carbon monoxide and combustion is no different.   NCI certified contractors have attended classes, used specialized equipment and are constantly up-to-date on the latest diagnostic and repair techniques in these fields.

An NCI certified technician at D.Silvestri Sons has passed a recognized testing process which validates his or her understanding of the technology and procedures used in this field. In addition NCI monitors their certified contractors and requires recertification every 2 years.
