Your building depends on more than comfortable air.
Heating and cooling problems can affect employees, customers, inventory, equipment and day-to-day operations.
Nick Dolinic Heating & Cooling provides commercial HVAC service for businesses throughout the St. Louis area. We work with owners, managers and facilities teams to diagnose problems, maintain equipment and plan replacements with as little disruption as practical.

From rooftop units to split systems and other commercial equipment, we provide practical service based on the needs of the building.

Airflow & controls

Commercial HVAC problems do not wait for a convenient time.
Unexpected downtime can disrupt staff, customers and normal operations.
When a commercial system is not operating correctly, our goal is to help you understand the issue quickly and determine a practical path forward.
