The main services involved in HVAC (Heating, Ventilation, and Air Conditioning) system maintenance include:

1. Inspection and Cleaning

• Air Filters: Regularly replacing or cleaning filters to improve air quality and system efficiency.
• Coils (Evaporator and Condenser): Cleaning the coils ensures that the system can absorb and dissipate heat effectively.
• Blower Motor and Fan: Inspecting and cleaning blower components to ensure air moves freely and efficiently.
• Ductwork Inspection: Checking for leaks, blockages, or contamination (dust, mold) in the ducts.

2. Checking Refrigerant Levels

• Refrigerant Leak Detection: Ensuring there are no refrigerant leaks, which can affect the system&rsquos cooling capacity.
• Recharging Refrigerant: Refilling the system if the refrigerant levels are low, optimizing cooling performance.

3. Thermostat Calibration

• Testing and adjusting the thermostat to ensure it's reading accurately and maintaining the desired temperature.

4. Electrical Component Inspection

• Wiring and Connections: Ensuring all electrical connections are secure to avoid malfunctions or hazards.
• Capacitors and Contactors: Checking for signs of wear or failure, which can disrupt system operations.

5. Lubricating Moving Parts

• Lubricating components such as motors, fans, and belts to reduce friction and prevent wear.

6. Checking System Controls

• Verifying that the start cycle, operation, and shutdown sequence are functioning properly.

7. Condensate Drain Cleaning

• Drain Pan & Drain Line: Cleaning and inspecting to prevent water damage and improve efficiency.

8. Airflow and Ventilation Assessment

• Testing for proper airflow through the vents to ensure consistent heating and cooling.

9. Energy Efficiency Checks

• Evaluating the system's overall performance to identify any inefficiencies or potential upgrades to save energy.

10. Performance Testing

• Running the HVAC system to assess how efficiently it&rsquos heating or cooling the space, and if there are any abnormal noises or vibrations.

11. System Tune-Up

• Fine-tuning the system to ensure optimal operation and to extend the life of the equipment.

Regular maintenance helps in improving system efficiency, lowering energy costs, and extending the life of the HVAC system.
