When Michael and Jessica Wolf bought their 1911-built Craftsman home in the South Park area of San Diego, it came with the original furnace and a lot of air leakage. "The house was very drafty with air coming in through the windows and floors," recalls Michael.
To make the home more comfortable, the couple incorporated energy upgrades into their remodel plans. Improvements included new ducts, air sealing, attic and wall insulation and a tankless water heater. They also had dual-pane windows and ENERGY STAR appliances installed.
