What size Gas pack unit is needed for 1300 square feet mobile home?

To determine the appropriate size of a gas pack unit for a 1,300 square foot mobile home, a common rule of thumb is to use 30 to 60 BTUs per square foot, depending on factors like climate, insulation, and the home's layout. This means you would typically need a unit with a capacity of approximately 39,000 to 78,000 BTUs. It's advisable to consult with an HVAC professional who can perform a load calculation for more accurate sizing based on specific conditions.
