When it’s time to complete your installation, the contractor will handle the job. You’ll need to schedule the installation. Make sure your contractor has access to the installation area. Most furnaces are installed in the home. You should be home on installation day to allow the contractor into your home. When installing air conditioner or heat pump exterior units, ensure your contractor has access to the area. Unlock gates and clear away brush and debris.
Really, that’s all you need to do. Your contractor will handle the actual installation of equipment. They will make sure the new system is connected correctly to perform as you expect.
