I recently completed a job installing two 2 18-year-old carrier split systems in a home in Alaska. The systems were installed on the roof and included a condenser, evaporator, and air handler. The job required careful planning and execution to ensure that the systems were installed correctly and efficiently. I worked closely with the homeowner to choose the right equipment for their needs and to ensure that the installation was done in a way that would minimize the impact on their home and their energy bills. The job also required careful attention to detail, including ensuring that the electrical connections were properly made and that the systems were properly sealed and insulated. Overall, the job was a success, and the homeowner was very pleased with the results.
