AC Maintenance in Des Plaines

Why Annual AC Maintenance Matters in Des Plaines

• Reliable Cooling on Day One: Des Plaines summers often top 90 °F by May. A pre-season tune-up catches worn belts, low refrigerant, or failing capacitors before you swelter through the first heat wave.
• Energy-Bill Savings: Dirty condenser or evaporator coils force your AC to work 15–25 % harder. Regular cleaning and calibration translate directly into lower cooling costs in our rising-rate energy market.
• Extended Equipment Life: Loose wiring, worn bearings, or minor refrigerant leaks escalate into major failures if unchecked. Proactive maintenance delays costly compressor or coil replacements—saving thousands on a new system.
• Improved Indoor Air Quality: Clean filters and coils remove dust, pollen, and allergens—essential for families near Forest Preserve Elementary who track in seasonal debris.
• Fewer Emergency Repairs: Catching small refrigerant leaks or motor wear in spring avoids breakdowns during peak season—when same-day parts may be scarce and repair costs surge.
• Warranty Compliance: Many manufacturers require proof of annual professional service to honor warranties. Skipping maintenance risks voiding coverage for major components right when you need it most.

Our 12-Point AC Maintenance Checklist

At DTSOL, we leave no bolt unturned. Here's our thorough spring tune-up protocol:

1. Safety Shut-Off & Visual Inspection - Kill power at the outdoor disconnect and breaker. Clear debris, leaves, grass clippings, and nests from around the condenser—maintain at least 2 ft of clearance.
2. Filter Replacement & Blower Cleaning - Install a new MERV-rated filter; demonstrate monthly checks. Vacuum the air handler's blower housing and return-air grille to remove built-up dust.
3. Coil Cleaning & Fin Straightening - Remove surface grime from condenser and evaporator coils with a no-rinse coil cleaner. Straighten bent fins using a fin comb to restore optimal airflow.
4. Electrical Connection Tightening - Torque all contactor, relay, and terminal connections to manufacturer specs—loose wires cause arcing and premature failures.
5. Capacitor & Contactor Testing - Meter-test start and run capacitors; replace any more than 10 % out of spec. Inspect the contactor for pitted or welded contacts; replace if necessary.
6. Lubrication of Moving Parts - Oil condenser and blower motor bearings (where service ports exist) to reduce friction and noise.
7. Refrigerant Pressure & Leak Detection - Attach manifold gauges; compare high and low-side pressures to manufacturer specifications (e.g., R-410A: 400/150 PSI). Introduce UV dye or electronic leak detector; repair any leaks via precision brazing.
8. Drain Line & Pan Service - Flush the condensate drain with a bleach-vinegar solution to clear slime and algae. Treat the drain pan with an antimicrobial tablet to inhibit mold growth.
9. Blower Motor & Airflow Verification - Balance and clean the blower wheel; clamp-meter blower motor amps against nameplate ratings. Measure airflow at registers—aim for 400–450 CFM per ton of cooling capacity.
10. Thermostat Calibration & Sensor Check - Compare thermostat readings to a calibrated room thermometer; recalibrate or replace batteries. Inspect sensor placement and wiring for accurate temperature control.
11. Startup & Performance Testing - Restore power; run several full cooling cycles. Measure supply vs. return air ΔT (should be 16–20 °F) and verify stable pressures, amperages, and temperatures.
12. Customer Walk-Through & Service Report - Deliver a detailed checklist documenting all tasks, findings, and recommended repairs. Demonstrate filter changes, thermostat programming, and answer any homeowner questions.
