AC Maintenance & Tune-Up Services in Santa Clarita, CA

Our Comprehensive 21-Point AC Tune-Up

When you schedule a tune-up with us, we perform a thorough inspection and servicing of your entire air conditioning system. Our technicians follow a detailed checklist ensuring nothing is missed.

Thermostat Testing and Calibration

We verify your thermostat reads temperature accurately, test all functions including cooling, fan, and programming, replace batteries if needed, ensure proper placement away from heat sources, and calibrate settings for optimal efficiency. Even a thermostat reading 2-3 degrees off can significantly impact comfort and energy use.

Electrical System Inspection

We thoroughly test electrical components including measuring voltage and amperage to verify proper power supply, testing capacitors with specialized meters to identify weak components before they fail, inspecting contactors for pitting, burning, or corrosion, checking all wiring connections for tightness and corrosion, and testing the condensate pump (if equipped) to ensure proper drainage.

Refrigerant Level Check

Proper refrigerant charge is critical for efficient cooling. We measure refrigerant pressure and temperature, calculate superheat and subcooling to verify correct charge, check for signs of leaks, and add refrigerant if needed (additional charge applies). Systems should never need refrigerant added unless there’s a leak, so if we find low refrigerant, we locate and repair the leak.

Coil Cleaning and Inspection

Dirty coils are a primary cause of efficiency loss. We clean condenser coils (outdoor unit) removing dirt, leaves, and debris, inspect evaporator coils (indoor unit) for dirt and mold, apply coil cleaner to remove stubborn deposits, check fin condition and straighten if bent, and verify proper airflow across coils.

Air Filter Replacement

We install a new, high-quality air filter (included in tune-up price), recommend the appropriate MERV rating for your needs, check filter fit to prevent air bypass, and provide guidance on filter change frequency based on your specific situation. Most homes need filter changes every 1-3 months depending on factors like pets, allergies, and system runtime.

Condensate Drain Cleaning

Clogged drain lines cause water damage and system shutoffs. We flush drain lines with appropriate solutions, clear blockages from algae or debris, verify proper slope for drainage, test safety shutoff switches, and add algae treatment tablets to prevent future growth.

Blower Motor Service

The blower motor circulates air throughout your home. We lubricate motor bearings (if applicable), clean blower wheel of accumulated dirt, check motor mounts and belts, measure amp draw to identify motor wear, and verify proper airflow (CFM) at registers.

Ductwork Inspection

We perform a visual inspection of accessible ductwork, check for disconnected or loose sections, identify major leakage points, verify register airflow balance, and recommend duct sealing if significant leakage is found. Duct leakage can waste 20-30% of cooled air.

Safety Controls Testing

We test all safety devices including high-pressure switches, low-pressure switches, float switches on drain pans, and emergency shutoffs. These critical safety features protect your system from damage and your home from water leaks.
