Our Air Conditioning Services
AC Maintenance & Tune-Ups
Spring maintenance (April–May, before peak cooling) keeps your system running all summer efficiently.
Our technicians clean coils, check refrigerant levels, inspect electrical connections, test thermostats, and replace filters. Join our Maintenance Plan for seasonal check-ups, priority scheduling, 24/7 emergency service, and exclusive repair discounts.
AC Installation & System Upgrades
Your AC is over 10 years old, costing more to run each month. We assess your cooling needs and recommend the right system—central air for whole-home cooling, or ductless mini-splits for homes without ductwork.
Our certified technicians install to manufacturer specs, protecting your warranty and ensuring peak efficiency. A new high-efficiency AC system pays for itself through energy savings.
AC Repair & Emergency Service
Your AC won't turn on, blows warm air instead of cold, or shuts down on the hottest days.
Call us for same-day service—we diagnose the problem, explain what went wrong, and fix it fast. We handle refrigerant leaks, compressor failures, thermostat issues, and capacitor problems. Most repairs finish the same day because we keep parts locally stocked. Small repairs today prevent catastrophic failures mid-summer when every contractor is swamped.
