  2. Arrival & Preparation: Our team arrives on time, checks in, and protects your floors and furniture. We walk you through the installation plan so everyone is on the same page.
  3. Old System Removal: If we’re replacing your existing unit, we safely remove it and handle disposal, so you don’t need to coordinate multiple services.
  4. System Setup & Installation: We inspect the installation area, prepare electrical connections, and ensure outdoor and indoor components are level and properly aligned. Then we install, connect, and charge your new system.
  5. Testing & Quality Check: Once installed, we test airflow, temperature consistency, and system operation to ensure optimal performance.
  6. Walkthrough & Support: We show you how to operate your thermostat, explain filter maintenance, and review your system’s warranty.
  7. Ongoing Care: We offer maintenance programs to keep your AC running efficiently for years. Our goal is to provide long-term comfort and peace of mind.
