I was hired to install an attic heat pump in a home. The heat pump was a high-efficiency unit that provided both heating and cooling for the entire house. The installation process involved removing the old furnace and ductwork, installing the heat pump, and connecting it to the existing electrical and plumbing systems. I also installed a thermostat and a programmable controller to allow the homeowner to control the temperature of the house. The installation took several days, but the homeowner was very pleased with the results.
