AC Maintenance in Glenview

Why Annual AC Maintenance Matters in Glenview

• Reliable Cooling on Day One: Glenview highs can soar into the 90s by May. Seasonal tune-ups catch worn belts, low refrigerant, or failing capacitors before you swelter.
• Energy-Bill Savings: Dirty coils force your AC to work 15–25% harder. Regular cleaning and calibration translate directly into lower utility bills in our rising-rate energy market.
• Extended Equipment Life: Loose wiring, rusted bearings, or minor refrigerant leaks escalate into major failures if unchecked. Proactive maintenance delays costly compressor or coil replacements—saving thousands in Glenview's premium home market.
• Improved Indoor Air Quality: Clean filters and coils remove dust, pollen, and allergens—vital for families near Gallery Park who contend with seasonal pollen and active-wear allergens.
• Warranty Compliance: Many manufacturers require annual professional service to honor warranties. Skipping tune-ups risks voiding coverage just when you need it most.
• Fewer Emergency Repairs: Identifying small refrigerant leaks or motor wear in spring avoids breakdowns during peak cooling season—when same-day parts may be scarce.

Our 12-Point AC Maintenance Checklist

1. Safety Shut-Off & Visual Inspection - Turn off electrical power at the breaker and close the gas valve. Check for proper clearance around the furnace, rust, leaks, or signs of rodent activity.
2. Filter Replacement - Install a new high-efficiency MERV-rated filter; demonstrate monthly checks and replacements.
3. Burner & Heat Exchanger Cleaning - Remove and scrub burners to clear soot and debris. Vacuum the heat exchanger to promote even combustion and prevent hot-spot corrosion.
4. Ignition System & Flame Sensor Service - Measure hot-surface ignitor resistance (~40 Ω) or assess pilot-flame quality. Polish the flame sensor tip with fine steel wool to prevent nuisance lockouts.
5. Blower Assembly Maintenance - Remove the blower wheel; clean and lubricate bearings. Measure motor amperage against the nameplate; tighten mounting screws.
6. Gas Pressure & Leak Check - Use a manometer to verify manifold pressure (3.5–5 in W.C.). Apply soapy water to all gas fittings; ensure zero leaks before restoring service.
7. Draft & Vent Inspection - Test draft pressure in the flue or PVC vent (–0.02 to –0.05 in W.C.). Clean vent paths of debris, nests, or soot that can block exhaust.
8. Thermostat Calibration & Cycle Testing - Compare thermostat readings to a calibrated thermometer; adjust or replace misreading stats. Run multiple heat cycles to confirm accurate responses and proper staging.
9. Electrical Connection Tightening - Inspect and torque all wiring connections, contactor coils, and control terminals.
10. Safety Controls Audit - Test high-limit switches, rollout sensors, and pressure switches for proper operation.
11. System Performance Testing - Measure temperature rise across the furnace (30–40 °F ΔT). Verify stable operation over multiple cycles without unusual sounds or odors.
12. Customer Walk-Through & Report - Provide a detailed checklist of all services performed, parts replaced, and recommended next steps. Demonstrate filter changes, thermostat programming, and answer any homeowner questions.
