Our team has completed hundreds of air conditioning projects across Fresno and the Central Valley. From AC repair in Fresno to full system replacements and advanced diagnostics, every project reflects our system-based approach to HVAC.
Complete System Overhaul & Clean Install
North Fresno, CA This homeowner’s aging AC was struggling to cool the upstairs bedrooms and driving up energy bills. We removed the old unit and installed a new, high-efficiency system with perfectly sealed duct connections and clean wiring. The home now cools evenly in minutes, and the system runs whisper-quiet.
Split System to Package Unit Conversion Fresno, CA
The Problem: The homeowner was dealing with severe, persistent humidity buildup inside an interior closet. Upon inspecting their existing split system, we uncovered a disastrous installation by a previous contractor. They were attempting to pump condensation out of the attic and had improperly crammed the electrical wiring, Freon lines, and condensation drains through a single, overcrowded roof jack.
The Solution: To permanently eliminate the indoor moisture and correct the hazardous roof penetrations, we recommended transitioning to a streamlined rooftop package unit. We completely removed the problematic indoor equipment, installed the new package system, cleanly reconnected the ductwork, and performed a comprehensive air balance across the entire home.
The Result: The closet humidity issue is completely gone, the roof is safely and correctly sealed, and the homeowner now enjoys highly efficient, perfectly balanced airflow in every room. View Project Folder
The Complete HVAC Scan Catch & Coil Restoration Madera, CA
The Problem: The homeowner was struggling with poor airflow and inconsistent cooling. Our Complete HVAC Scan uncovered several hidden dangers behind the panels: loose insulation actively blocking the indoor coil, a filthy outdoor coil, burned electrical contacts, and a failing blower motor pulling dangerously high amps.
The Solution: We executed a full system restoration. We permanently secured the insulation, deep-cleaned the coils to restore heat transfer, and replaced the degraded electrical components. We also designed a custom mini-split system to cool their garage and second living space.
The Result: We completely restored the airflow, achieving a perfect 59-degree supply air temperature. By catching the failing motor and overheating board early, we saved the expensive compressor and brought the entire system back to peak efficiency.
