By following these preventive maintenance steps, you can help to ensure that HVAC systems operate efficiently, reliably, safely, and with minimal downtime
Check and replace air filters: Dirty air filters can cause poor indoor air quality and reduce system efficiency, check and replace air filters regularly.
Inspect and clean coils: Dirty coils can reduce system efficiency and cause breakdowns, inspect and clean coils regularly.
Lubricate moving parts: Moving parts such as motors, bearings, and fans need regular lubrication to prevent wear and tear.
Check electrical connections: Loose or damaged electrical connections can cause system failure or even fire hazards, check electrical connections regularly.
Test safety controls: Safety controls such as pressure switches, limit switches, and flame sensors need regular testing to ensure they are functioning properly.
Check refrigerant levels: Low refrigerant levels can cause poor system performance and damage to the compressor, check refrigerant levels regularly.
Clean condensate drains: Clogged condensate drains can cause water damage to the building or even mold growth, clean condensate drains regularly.
Inspect belts and pulleys: Worn belts or pulleys can cause system failure or reduce efficiency, inspect belts and pulleys regularly.
Calibrate thermostats: Incorrect thermostat calibration can cause poor temperature control or even system failure, calibrate thermostats regularly.
Conduct a general inspection: A general inspection of the entire HVAC system, including ductwork, insulation, and ventilation components, to identify any potential issues that may require attention.
