San Fernando Valley AC Tune-Ups & Maintenance

Our tune-ups go beyond a quick look. We inspect, clean, and calibrate every part of your AC system to keep it running smoothly and efficiently all season long.

Cooling Performance & Efficiency

✅ Thermostat Calibration – We make sure your thermostat reads correctly and communicates properly with your system.

✅ Evaporator and Condenser Coil Cleaning – Dust and grime on the coils can restrict airflow and reduce cooling power. We clean them thoroughly to restore efficiency and keep your system running smoothly.

✅ Refrigerant Level Check & Pressure Testing – We ensure your system has the proper refrigerant charge and inspect for any signs of a leak or imbalance.

✅ Temperature Split Measurement – We check the difference between return and supply air to confirm that your system is cooling as it should.

✅ Smart Thermostat or Zoning System Calibration – If your system includes smart controls or zoning, we test and calibrate them to ensure accuracy and functionality.

✅ Fan Blade Inspection – We check blades on both the indoor and outdoor units for cracks, warping, or imbalance.

✅ Compressor Performance Check – We verify that your compressor is operating efficiently and not overworking, which could lead to system failure.

✅ Refrigerant Line Insulation Inspection – We inspect insulation for cracks or damage that can affect performance and increase energy use.

Airflow & Circulation

✅ Air Filter Replacement or Cleaning – Clean filters improve air quality, prevent strain on the system, and ensure proper airflow.

✅ Blower Motor Inspection – We evaluate the blower motor to ensure it’s delivering consistent airflow and not showing signs of wear.

✅ Ductwork Visual Inspection – We visually inspect accessible ducts for disconnections, blockages, or visible damage.

✅ Fan Belt Condition (if applicable) – In systems with belts, we check for signs of fraying, tension loss, or misalignment.

Electrical & Safety Systems

✅ Electrical Connection Tightening – Loose connections are a major cause of breakdowns. We inspect and tighten all key terminals and wiring.

✅ Capacitor & Contactor Testing – We test these components to ensure your system starts and runs reliably without electrical issues.

✅ Voltage & Amperage Checks on All Motors – We measure motor loads to catch early warning signs of stress or failure.

✅ System Controls & Safety Check – We inspect the control board, relays, and safety systems to ensure reliable operation.

✅ Surge Protection Check (if installed) – We confirm that your system’s surge protector (if installed) is in place and functioning.

✅ Secure All Panels & Covers – We reseal access panels after service to prevent air leaks, vibration, or damage.

✅ Noise & Vibration Evaluation – Unusual sounds or vibrations often point to loose parts or developing problems—we catch them early.

✅ System Startup & Shutdown Test – We run a full system cycle to confirm smooth, reliable operation from start to stop.

Drainage & Moisture Control

✅ Condensate Drain Line Cleaning – We flush the drain line to prevent clogs that could cause water damage or mold growth.

✅ Safety Shut-Off Switch Testing (if applicable) – We test any safety shut-offs to ensure they’ll trigger properly in case of a leak or overflow.

Preventive Maintenance & Documentation

✅ Lubrication of Moving Parts – We lubricate motors and other components to reduce friction and extend system life.

✅ Document System Age, Model, and General Condition – We note your system’s specs and condition so you have a clear service history and replacement roadmap.
