We just built a family room addition onto our home as part of a house renovation project me and wife did.
Everything is pretty much done except getting heating and air conditioning into the family room that we had built onto the house.
We had thought about getting a ductless mini split air conditioning system and then having it converted into a full on ductless heating and cooling unit. However, that would prove to be more expensive than just having additional ductwork laid and created. So that was what we decided to do. It was pretty easy surprisingly. All I had to do was call the local heating and air conditioning company to order the work. Then it was a matter of scheduling a few days in advance to have them send out a crew of certified heating and cooling specialists to come and both build the add on needed and then lay the additional ductwork. That way we would not have to invest in any additional heating and air conditioning equipment. We could just have our regular central heating and air conditioning system work for the new family room as well. We had the ductwork built and laid within 2 weeks of making the decision and making the phone call to the local heating and air conditioning company. I was pretty happy with the overall results. Our family room now has the same great and most powerful heating and air conditioning as we do throughout the rest of our home. It helps that we recently bought a brand new and up to date central heating and air conditioning unit.
