Adding HVAC to a house
My current house does not have central heat or air. Currently it has baseboard heat and a pellet stove(which I mainly use). However when they built the house they put in some ducting and hooked up a stationary swamp cooler outside. I want to get rid of the swamp cooler and put in an HVAC system. Currently there is only about 1 vent per room which i'm sure isn't nearly enough and I understand I would have to add more venting. Would it be feasible to even use the current duct work that is there? What options/alternatives are there? This house was built in about 1989.
