- Testing thermostat function.
- Checking electrical connections and components.
- Lubricating moving parts.

Routine maintenance helps identify minor issues before they turn into costly repairs, improves air quality by ensuring clean components, and keeps your system running efficiently, which can help lower your energy bills.
