The size of a gas furnace for a 3,800 square foot house generally depends on factors like climate, insulation, and the home's layout. However, a rough estimate for heating capacity is around 30 to 35 BTU (British Thermal Units) per square foot. This would suggest a furnace with a capacity of approximately 110,000 to 133,000 BTUs. It's best to consult with a professional HVAC contractor for a precise calculation tailored to your specific home conditions.
