We have a 0% loan through a CT org to make some insulation/heating duct improvements. BUT we can't afford to do more than $2,500 of work this year. This means we can EITHER get the ducts in the house sealed (ecs-aeroseal.com is a company that seals the ducts in the walls - which is a big problem area for us) OR we can spray foam the floor of the family room, which is the largest room in the house (35X20 ish) and where the wood stove is located. The MBR is above. There is currently no insulation under the floor. The ducts are also not sealed and there are definitely leaks in the walls (cold a/c air blowing through electrical outlets and llight switches etc., poor air circulation/little/no heat to 2nd floor). So there's no doubt both need to be done - but which should be done first?
