Pre-Installation Preparations - Setting the Stage for Success

Before you roll up your sleeves and start installing your AC, it’s crucial to set the stage for success. This step lays the foundation for a smooth process, so let’s begin by:


  • Evaluating Your Needs: Consider your cooling requirements, the size of your space, and your budget. This step is critical in selecting the right system for your home.
  • Permits and Regulations: Check local regulations and obtain any necessary permits. Compliance is essential to avoid legal complications.
  • Selecting the Right Unit: Choose an energy-efficient AC system that suits your needs and budget. An oversized unit can waste energy and money, while an undersized one won’t effectively cool your space.

Gathering Tools and Materials - The Building Blocks of AC Installation

We recommend you use the appropriate tools and materials for your successful AC installation in Suwanee, GA. Here’s what you’ll require:

Disconnecting Existing Systems - A Safe Start

A safe start is a successful start. Before you can proceed with your new AC unit, you must first safely disconnect the old one. Here’s how:

  • Power Off: Turn off the power to your existing AC system at the circuit breaker.
  • Disconnect Wiring: Unhook the wiring connections from the old system.
  • Refrigerant Handling: Safely remove and dispose of the refrigerant from the old system. It’s essential to adhere to environmental regulations in this step.

Now comes the exciting part – installing your new AC system. This step is where the pieces start coming together, so let’s proceed by:

  • Mounting the Unit: Carefully secure the new unit on its mounting brackets.
  • Connecting Wiring: Attach the electrical wires following the manufacturer’s instructions.
  • Refrigerant Lines: Connect the refrigerant lines, ensuring they’re properly insulated.
  • Drainage Setup: Establish a proper drainage system to channel condensation away from your home.
