1. Comprehensive System Diagnostics & Troubleshooting

We begin every service with thorough system analysis to pinpoint the exact cause of cooling failure. Our technicians utilize advanced diagnostic equipment including digital manifolds, multi meters, and refrigerant leak detection to assess system health.

What We Check:

• Refrigerant pressures and superheat/subcooling values

• Compressor operation and amperage draw

• Evaporator and condenser coil conditions

• Airflow across evaporator and supply diffusers

• Thermostat calibration and control wiring

• Electrical connections and component operation

Outcome: Accurate identification of issues ensures we repair the root cause—not just the symptoms—preventing recurring failures.

2. Refrigerant Leak Detection & Recharging

Low refrigerant is a leading cause of poor cooling performance and system damage. Our technicians specialize in pinpointing and sealing leaks, then recharging the system to manufacturer specifications for optimal cooling capacity.

Our Process:

• Electronic leak detection and ultraviolet (UV) dye injection for precise leak location

• Professional repair of leaks in coils, tubing, or fittings

• Proper evacuation and dehydration of the system

• Precision recharging based on manufacturer specifications and ambient conditions

• Verification of subcooling and superheat for optimal performance

Why It Matters: Proper refrigerant charge ensures efficient cooling, protects the compressor from damage, and reduces energy consumption.

3. Compressor & Mechanical Component Repair

The compressor is the heart of your AC system. When it fails, cooling stops. We provide expert diagnosis and repair of compressor issues and all associated mechanical components.

Services Include:

• Compressor electrical testing (winding resistance, insulation, connactor condition)

• Start capacitor and relay replacement

• Compressor hard start kit installation

• Fan motor repair and replacement (condenser and blower motors)

• Bearing and belt replacement for air handlers

Our Commitment: We use only quality, manufacturer-approved replacement parts to ensure longevity and reliable operation.

4. Electrical & Control System Troubleshooting

Modern AC systems rely on complex electrical and control circuits. When electrical components fail, the system may not start, short cycle, or operate erratically. Our technicians are trained to diagnose and repair all electrical issues safely.

What We Repair:

• Failed connectors, relays, and circuit boards

• Thermostat wiring and calibration errors

• Capacitor and starting component failure

• High voltage and low voltage wiring issues

• Sensor and safety switch malfunctions

• Control communication errors in smart and zoning systems

Safety First: All electrical repairs are performed with power safely isolated and in strict compliance with National Electrical Code (NEC) requirements.

5. Preventive Maintenance & Performance Optimization

The best repair is the one you never need. Our preventive maintenance programs keep your AC system running efficiently, reducing the likelihood of unexpected breakdowns and extending equipment lifespan.

Maintenance Includes:

• Seasonal startup and shutdown inspections

• Coil cleaning and air filter replacement

• Refrigerant charge verification and adjustment

• Electrical connection tightening and connector inspection

• Drain line clearing and condensate pan treatment

• System performance testing and efficiency verification

Benefits of Preventive Care:

• Reduced emergency repair costs

• Lower energy bills through maintained efficiency

• Extended equipment service life

• Improved indoor air quality

• Consistent comfort with fewer temperature swings
