HVAC Services in St. Louis | Trane Dealer & Repair | Nick Dolinic Heating & Cooling

Not at all. While we are proud certified Trane dealers and experts in their installations, our over 20 years of experience means we service and repair all makes and models of HVAC equipment. Our goal is to provide the right solution for your St. Louis home, regardless of brand.

Our maintenance service, often called a Clean and Check, is designed to keep your system running efficiently and catch small issues before they become big problems. We perform a thorough inspection, clean essential components, check refrigerant levels, and ensure your system is safe and ready for the demanding St. Louis seasons, whether it's a furnace or air conditioner.

This is a common issue in our area, often an evaporator coil freeze-up. It's typically caused by restricted airflow from a dirty filter, low refrigerant levels, or a failing blower motor. We recommend turning the system off to let it thaw and calling us. Our technicians will diagnose the root cause—whether it's a leak needing a Freon charge or another repair—to restore cool, efficient airflow to your home.
