What's Included in This Service?

The process begins with an in-home assessment where the team evaluates your existing ductwork, electrical capacity, and square footage to determine the ideal system size and configuration. You'll receive clear recommendations that balance upfront investment with long-term energy savings, factoring in California's strict efficiency mandates and available utility rebates.

During installation, A-Z Techs Mechanical uses high-quality tools and tuned-in installation practices to maximize airflow and long-term reliability. Each connection is tested for refrigerant integrity, every duct joint sealed to prevent loss, and thermostats calibrated to deliver precise temperature control. If your home presents access challenges—narrow hallways, low ceilings, or minimal crawl space—the crew adapts routing and equipment placement without compromising performance.

After the system is live, you'll walk through operation basics, filter maintenance schedules, and warranty details so you feel confident managing your new cooling investment.
