What to Expect During an HVAC Maintenance Visit
A seasonal tune-up is a detailed review of the equipment that heats or cools your property. We assess its condition and efficiency, then discuss our findings before recommending any additional service.
Depending on the equipment and its condition, a maintenance visit may include:
- Filter Replacement: We replace the system filter as part of the maintenance plan.
- Thermostat Calibration: We confirm that the thermostat is calibrated correctly.
- Coil Inspection: We check coil cleanliness and address buildup that can affect performance.
- Refrigerant Level Checks: We evaluate refrigerant levels in applicable cooling systems.
- Condensate Drainage: We inspect the system that carries moisture away from cooling equipment.
- Efficiency Evaluation: We check for operating conditions that may cause unnecessary energy consumption.
Thorough maintenance can improve equipment performance, reduce energy use, and help control utility costs. If we uncover a developing problem, we’ll explain what we found and whether it needs attention now.
