What Happens During a Professional AC Tune-Up: Complete 8-Step Checklist
What Happens During a Professional AC Tune-Up: Complete 8-Step Checklist
Professional AC tune-up process performed by Intelligent Design's certified technicians during every maintenance visit in Tucson.
Complete System Inspection & Safety Check
Our technician begins with a comprehensive visual and operational inspection of your entire AC system. We examine the outdoor condenser unit for physical damage, corrosion, or debris accumulation; inspect the indoor air handler or furnace cabinet for rust, leaks, or component deterioration; check condensate drain lines for clogs or improper drainage that could cause water damage; verify thermostat operation and calibration accuracy; examine all visible ductwork for leaks, disconnections, or insulation damage; test safety controls including high-pressure cutouts and low-pressure switches; and inspect electrical disconnect boxes for proper fusing and connections. This initial assessment identifies immediate safety concerns and provides a baseline for performance testing.
Electrical Component Testing & Tightening
Electrical problems are the leading cause of AC failures in Tucson's heat. Our technicians use precision testing equipment to measure voltage and amperage at the outdoor condenser unit, verifying power supply is within manufacturer specifications; test capacitors with specialized meters checking microfarad ratings against factory specs (failing capacitors cause 34% of compressor failures); inspect and tighten all electrical connections including contactor terminals, compressor wiring, and fan motor connections; check contactor condition for pitting or burning that indicates replacement needs; verify proper ground connections for safety; test low-voltage control wiring for shorts or breaks; and measure amp draw on compressor and fan motors to detect mechanical problems before catastrophic failure. Loose connections cause resistance, generate heat, and can lead to component failure or even electrical fires.
Refrigerant Level Verification & Leak Detection
Proper refrigerant charge is critical for cooling efficiency and compressor protection. Our technicians connect professional manifold gauges to measure operating pressures; calculate superheat and subcooling to determine if refrigerant charge is precisely correct; use electronic leak detectors to scan all refrigerant connections, coil joints, and service ports for leaks; check for oil stains indicating previous or active refrigerant leaks; verify system is not overcharged (which damages compressor) or undercharged (which reduces cooling capacity 15-30%); and document exact refrigerant type and charge for future service reference. Low refrigerant never results from normal operation—it always indicates a leak requiring repair. We identify leak sources, provide repair estimates, and add refrigerant only after repairing leaks to prevent recurring problems.
Professional Coil Cleaning & Debris Removal
Clean coils are essential for efficient heat transfer and optimal cooling performance. Our technicians thoroughly clean outdoor condenser coils using specialized coil cleaning solutions and low-pressure washing that removes Tucson's cottonwood seeds, dust, pollen, and mineral deposits without damaging delicate aluminum fins; straighten bent fins with professional fin combs to restore proper airflow; remove all debris, leaves, and vegetation from around the outdoor unit; clean indoor evaporator coils using foaming coil cleaner that reaches deep between coil fins to remove dust, biological growth, and buildup; inspect coils for corrosion or leaks requiring attention; and verify proper drainage from evaporator coil drain pan. Dirty coils reduce cooling efficiency by 20-40%, force your compressor to work harder consuming more energy, and can lead to frozen evaporator coils or compressor overheating.
Air Filter Replacement & Airflow Optimization
Proper airflow is critical for AC performance, efficiency, and longevity. Our technicians replace your air filter with the correct size and MERV rating for your specific system; verify filter fits properly with no bypass gaps allowing unfiltered air; inspect blower wheel and motor for dirt accumulation or mechanical problems; measure temperature differential across evaporator coil (should be 15-25°F for optimal performance); check static pressure in duct system to identify airflow restrictions; verify all supply and return vents are open and unblocked; lubricate blower motor bearings if applicable to your system; and adjust blower speed if needed for proper airflow volume. In Tucson's dusty environment, we recommend filter changes every 30-60 days versus the standard 90-day interval—dirty filters are the #1 cause of AC system failures in Southern Arizona.
Condensate Drain System Cleaning & Testing
Tucson's low humidity means condensate systems see less use than humid climates, but monsoon season and high-efficiency systems still produce significant moisture requiring proper drainage. Our technicians flush condensate drain lines with specialized cleaning solution or compressed air to remove algae, mineral buildup, and debris; clean condensate drain pans removing slime, biological growth, and sediment; verify proper drain line slope and connection to household drainage; test condensate safety switch operation to ensure it shuts off AC if drain backs up preventing water damage; inspect drain line insulation to prevent condensation on cold pipes; and add algae prevention tablets to drain pan if recommended for your system. Clogged condensate drains cause water damage, promote mold growth, and trigger safety shutoffs leaving you without cooling.
Thermostat Calibration & System Performance Testing
Your thermostat controls when and how your AC operates—accuracy is essential for comfort and efficiency. Our technicians verify thermostat is level and securely mounted; clean dust from inside thermostat housing; check batteries in wireless thermostats or battery-backup models; calibrate temperature sensors using precision thermometers; verify thermostat cycles system on and off at proper temperature differentials; test all operating modes (cooling, fan-only, auto/on settings); check smart thermostat WiFi connectivity and app functionality; verify programmable schedules are set correctly; and adjust anticipator settings on older thermostats for optimal cycling. We also educate homeowners on efficient thermostat settings for Tucson climate: 78-80°F when home, 82-85°F when away, and using programmable features to pre-cool before returning home rather than overcooling to compensate.
Comprehensive System Testing & Performance Documentation
Final testing verifies your AC is operating at peak efficiency and safety. Our technicians run complete cooling cycles while monitoring system performance; measure supply and return air temperatures to calculate actual cooling capacity; verify proper system cycling times (should run 15-20 minutes per cycle, not short-cycling); listen for unusual noises indicating mechanical problems; check for proper outdoor fan operation and direction; verify refrigerant temperatures and pressures under load match manufacturer specifications; test all safety controls and limit switches; photograph any conditions requiring attention; and provide you with a detailed written report documenting all findings, measurements, and recommendations. This documentation proves maintenance was performed for warranty purposes, helps track system performance over time, and gives you clear information about your AC's condition and any developing issues to address before they become expensive failures.
