AC Maintenance in Northbrook: Fast, Friendly, and Local

Common Northbrook Warning Signs

Spot these red flags and call us before your system quits:

• Uneven Cooling - Rooms near Meadowhill Road stay frigid while others feel lukewarm.
• Weak Airflow - Sputtering vents by the Metra station signal a clogged blower or filter.
• Strange Noises - Squeaks or rattles from your outdoor unit near Cherry Lane often mean loose parts or failing bearings.
• Frost or Ice on Coils - Dirty evaporator coils freeze up, shutting down your system.
• Spike in Energy Bills - A sudden 20 % jump usually ties back to efficiency losses from dirt buildup or failing components.

Ignoring these leads to late-night emergency calls—nobody wants that in Northbrook's summer storms.

Our 10-Point Maintenance Checklist

We go beyond filter swaps—here's our full tune-up:

• Safety Shut-Off & Visual Inspection - Kill power at the disconnect; clear debris, leaves, and yard waste from the condenser.
• Filter Replacement - Swap in MERV-rated filters; show you how to check monthly.
• Coil Cleaning - Apply foam cleaner to condenser and evaporator coils; rinse gently to avoid damage.
• Refrigerant Level Check - Gauge pressures; top off to manufacturer specs and seal minor leaks with UV dye.
• Electrical Connections - Tighten all lugs, inspect capacitors and contactors for wear.
• Blower Assembly Service - Clean wheel, measure motor amps, lubricate bearings where applicable.
• Condensate Drain Flush - Blow out and treat drain line to prevent clogs and basement overflows.
• Thermostat Calibration - Verify stat accuracy against a handheld gauge; adjust as needed.
• Lubrication of Moving Parts - Oil fan motor bearings on older units for quiet operation.
• Final Safety & Performance Audit - Run full cooling cycle; confirm 16–20 °F temp drop and listen for any abnormal sounds.
