Another San Francisco home upgraded with a new 95% efficient Payne furnace.
This upgrade included a new supply plenum, return duct, filter box, fresh air intake, condensate management, insulated metal surfaces, and a complete airflow balance. Before finishing, we verified safe operation with a carbon monoxide test — 0 ppm. Reliable heat, cleaner airflow, and peace of mind for years to come.
