AC Maintenance in Libertyville

Why Annual AC Maintenance Matters in Libertyville

• Ensure Reliable Cooling on the First 80 °F Day - Libertyville summers can hit 90 °F by late May. Neglected systems seize mid-season, leaving you sweltering on the hottest days.
• Maximize Energy Efficiency - A dirty coil or clogged filter forces your unit to work 15–25 % harder. Regular cleaning and calibration save on utility bills in Libertyville's rising energy market.
• Extend Equipment Lifespan - Small issues—loose wiring, low refrigerant, worn bearings—escalate into major failures. Proactive maintenance delays costly compressor or coil replacements.
• Protect Indoor Air Quality - Clean filters and coils remove dust, pollen, and allergens before they circulate—vital for families near the Des Plaines River Trail who track in seasonal pollen.
• Preserve Manufacturer Warranties - Most HVAC warranties require annual professional tune-ups. Skipping them can void coverage just when you need it most.
• Prevent Emergency Repairs - Catching minor refrigerant leaks or motor wear during spring avoids breakdowns in peak cooling season—when same-day parts are scarce.

Our 12-Point AC Maintenance Checklist

At DTSOL, we leave no bolt unturned. Here's our comprehensive pre-season protocol:

• Safety Shut-Off & Visual Inspection - Kill power at the outdoor disconnect and breaker. Walk the perimeter: check for debris, plants, and nests blocking airflow around the condenser.
• Filter Replacement & System Cleaning - Swap in a new MERV-rated filter; demonstrate monthly filter checks. Clean blower housing and return-air grill to remove dust buildup.
• Coil Cleaning & Fin Straightening - Remove debris from condenser and evaporator coils; apply coil cleaner to dissolve grime. Straighten bent fins with a fin comb to restore optimal heat exchange.
• Electrical Connection Tightening - Inspect and torque all contactor, relay, and terminal connections to factory specs—loose connections cause arcing and failures.
• Capacitor & Contactor Tests - Meter-test start/run capacitors; replace any more than 10 % off rating. Verify contactor operation; replace worn contacts.
• Lubrication of Moving Parts - Oil condenser and blower motor bearings where applicable; reduce friction and noise.
• Refrigerant Pressure & Leak Detection - Gauge high/low pressures; adjust charge if within 2 oz of spec. Introduce UV dye to catch slow leaks; repair brazed fittings as needed.
• Drain Line & Pan Service - Flush condensate drain with a bleach-vinegar solution; clear algae and clogs. Treat drain pan with an antimicrobial tablet to prevent mold.
• Blower Motor & Wheel Inspection - Measure blower wheel for dust accumulation; clean and rebalance if wobbly. Clamp-meter blower motor amps against nameplate ratings.
• Thermostat Calibration & Sensor Check - Verify thermostat setpoint vs. actual room temp; recalibrate or replace batteries. Inspect wired and wireless sensor placements for accurate readings.
• Startup & Performance Testing - Restore power; run cooling cycles. Measure supply vs. return air ΔT (should be 16–20 °F) and airflow (400–450 CFM per ton).
• Customer Walk-Through & Report - Provide a detailed service report of findings, cleaned components, and recommended future repairs. Demonstrate filter changes, thermostat programming, and report on system health.
