What to Expect On Your Installation Day

Our goal is to provide an enjoyable installation experience. The first step to a safe and sound installation is keeping you informed. Here is an overview of what you can expect on installation day.

  • We Call You: On your installation day, our team will notify you 30-60 minutes prior to their arrival.
  • Pre-Install Review: Before the installation begins, our team lead will provide an overview of the job and answer any questions or concerns you may have.
  • Installation Preparation: To keep the installation space clean and tidy, our team will cover the work area with drop cloths. We’ll also relocate any obstacles for the safety of you and our installation team. (Preparations may be completed prior to the installation day in the case of asbestos or hazardous materials.)
  • Turn Off the Power: Electrical breakers that power any existing HVAC systems are shut off.
  • Refrigerant Removal: When installing air conditioning equipment, we act in accordance with state and EPA guidelines and remove refrigerant in your current cooling system. We then dispose of it appropriately.
  • Equipment Removal: After safety precautions are completed, old equipment is disconnected and removed.
  • Site Preparation: The site is cleaned and prepared for installation.
  • Equipment Installation: After safely moving the new equipment to the appropriate location, we will set it in place, connect it to existing ductwork and wire it accordingly. To ensure load capacity, emergency disconnect boxes will be installed at each unit and electrical fuses are upgraded.
  • Equipment Pressurization: The system is pressurized and various functions are tested. This ensures that your system works correctly and there are no leaks.
  • Refrigerant Charging: If an air conditioner was installed and the equipment passes the pressurization test, it will be charged with environmentally-friendly refrigerant.
  • Thermostat Installation: We will mount and calibrate your chosen thermostat to ensure it works correctly.
  • Accessory Installation: Any accessories for your new system, like a whole-house humidifier or whole-house air cleaner, will be installed and tested.
  • System Startup: We will run the new system for a period of time to confirm that the equipment is operating correctly. Our team will also check that appropriate compressor amps are drawing and that the refrigerant is correctly charged.
  • Installation is Complete: After a successful system start-up, installation is complete. We will clean up the workspace, clear away drop cloths and make sure the area around the new system is tidy.
  • Post-Install Review: Our lead installer will give you a walkthrough to demonstrate how to operate your new cooling or heating system and answer any questions you may have about the installation process and your new equipment.
  • Final Paperwork: After all your questions have been answered and you are confident operating your new system, our lead installer will review all associated paperwork and warranty information.
  • Installation Inspection: After all paperwork is completed, the lead installer will request a date to schedule an inspection with your local jurisdiction. The inspectors will review our work and confirm that everything meets local and state codes.
