Full-Service HVAC Repair: From Diagnostics to Complete Fixes

Effective repairs require a comprehensive strategy that addresses both symptoms and root causes. Our process ensures every component functions harmoniously, delivering reliable performance.

Detailed System Assessment

We start by evaluating thermostat settings, electrical connections, and airflow patterns. Thermal imaging helps detect insulation gaps or blocked vents, while refrigerant pressure tests reveal leaks that compromise cooling capacity.

Component-Specific Repairs

We focus on precision, from replacing worn-out fan belts to sealing cracked heat exchangers. For example, dirty evaporator coils are cleaned using eco-friendly solutions to restore heat absorption, while malfunctioning capacitors are swapped to prevent compressor strain.

Post-Repair Performance Testing

After repairs, we conduct stress tests by running the system at maximum capacity. Real-time data logging ensures temperatures stabilize correctly and airflow meets manufacturer specifications, guaranteeing your unit operates as intended.

Tailored Maintenance Recommendations

Post-service, we provide actionable tips, such as replacing air filters monthly or scheduling biannual tune-ups. These practices reduce dust buildup and mechanical wear, keeping your system resilient against Fenton’s climate demands.
