Cornerstone Services

Cornerstone Services serves Norwood, New York, as a heating and cooling contractor with a 4.9-star average drawn from 488 customer reviews. The company maintains 24-hour availability Monday through Friday, responding to emergency heating calls throughout the region. Multiple reviewers specifically mentioned technicians arriving the same day during heating failures, and several praised the team's willingness to provide temporary heating solutions while awaiting permanent repairs. The contractor works on residential furnaces, air conditioning units, and advanced climate control systems including zoning configurations.

The contractor partners with Amana for furnace and cooling equipment, and reviewers mentioned installation of WiFi thermostats as part of system replacements. One customer described a complex heating imbalance scenario where bedroom temperatures reached 80 degrees while the rest of the home remained at 68 degrees. The technicians resolved this by installing a two-zone heating system, addressing temperature disparities that previous service calls had not solved. This type of system customization appears repeatedly in customer feedback as a distinguishing capability.

Customers consistently named individual technicians across multiple reviews. Luke performed diagnostic work on a furnace with multiple failing components, presenting the homeowner with repair options at different price points. Bill and Thaddeus handled a full system replacement, with one reviewer noting their cleanup left the home appearing untouched. The sales manager, Tom Sochia, guided customers through replacement decisions, including selection of complementary outdoor AC units. These named technicians appeared across separate reviews describing different jobs, suggesting a consistent team handling varied HVAC challenges.
