Spring HVAC Maintenance

Spring maintenance readies your cooling system for summer while properly shutting down your heating system after winter. Our spring service includes cleaning cooling coils, checking refrigerant levels, calibrating thermostats, and inspecting electrical components. We also clean or replace air filters, lubricate moving parts, and check condensate drains to avoid clogs that might cause water damage. This seasonal care helps avoid system failures during hot summer months and extends equipment life while maintaining energy efficiency.

Winter HVAC Maintenance

Winter maintenance focuses on reliable heating system performance during cold months. Our technicians inspect heat exchangers for damage, test ignition systems, examine flue pipes for ventilation, and verify gas or oil connections for safety. We also check airflow, test safety controls, inspect ductwork for leaks, and calibrate your thermostat for winter operation. Regular winter maintenance prevents unexpected breakdowns in freezing weather and identifies potential carbon monoxide risks, keeping your family safe and comfortable all season.
