Preventive HVAC Maintenance That Actually Pays For Itself

Commercial HVAC equipment rarely fails without warning. It fails after months of small, ignored symptoms.

The quarterly checklist

- Replace or clean filters and check static pressure - Inspect and clean condenser and evaporator coils - Verify refrigerant charge and superheat - Tighten electrical connections and check amp draw - Clear condensate drains and pans - Confirm economizer operation and damper linkage

Why it pays

Clean coils alone can restore 10-15% of lost efficiency. Catching a failing capacitor during a scheduled visit costs a fraction of an emergency call in August.
