I have been working on building a family room in my house. It is an extension so there is a lot of construction work going on that I have hired people to do. Me and my wife paid a lot of money on this so far and it is almost done. The only thing we have not figured out yet is what we are doing for heating and air conditioning. We have 2 choices. We can either have the local heating and air conditioning company send out some certified heating and air conditioning specialists to extend the ductwork of our central heating and cooling unit to reach the new family room and add some air vents. Or, we can invest in a ductless mini split air conditioning system and then call the local heating and air conditioning company to send out 1 single certified heat and a/c specialist to convert the ductless mini split air conditioning system into a full on ductless mini split heating and air conditioning system. Both are going to be an investment and pricey, but the real question is which will be the less expensive of the 2. This is something we are going to have to do some research on the internet on. This will be a task but well worth it because we want to spend the cheapest possible that is going to do the job. Because after all, we just dumped thousands into the construction of the extension of the brand new family room that is nearly done.
