Our AC Installation Process
We take an entirely different approach to air conditioning installation than standard condenser swaps. Our white-glove installation process focuses on custom system design and seamless home integration from start to finish.
Detailed Consultation and Load Calculation
We begin by consulting extensively with you to understand your home’s unique cooling needs. Our comfort advisors carefully evaluate square footage, sun exposure, insulation ratings, and air tightness. Using specialized calculation software, we pinpoint exact cooling load requirements and spec out a premium-matched system designed for optimized airflow and efficiency.
Strategic Site Preparation
Our installation technicians construct a proper concrete pad for your outdoor condenser, positioned for maximum airflow, accessibility, and aesthetic appeal. We complete all necessary electrical, drainage, and landscaping accommodations to ensure proper system function.
Indoor Integration and Ductwork Optimization
Inside your home, our specialists surgically position your new air handler to leverage existing ductwork and enhance whole-home airflow dynamics. We’re experts at modifying duct runouts, fabricating transitions, and sealing air leaks to eliminate turbulence and restrictive bottlenecks that could reduce cooling efficiency.
Comprehensive Quality Verification
Throughout the process, we rigorously quality check every installation detail. Our team meticulously verifies refrigerant charge levels, electrical functions, thermostat programming, and system cycling. Only after our comprehensive commissioning process is complete can we confidently certify your new installation is optimized for maximum efficiency, comfort, and longevity.
