The people I was with and I just built a family room addition onto our beach apartment as area of a apartment renovation project myself and others and wifey did, then everything is pretty much done except getting heating plus A/C into the family room that every one of us had built onto the house.
The people I was with and I had thought about getting a ductless mini split air conditioning idea and then having it converted into a full on ductless heating and cooling unit.
However, that would prove to be more high-priced than just having additional HVAC duct laid and created. So that was what every one of us decided to do. It was pretty straight-forward surprisingly. All I had to do was call the local heating plus A/C 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 HVAC duct. That way every one of us would not have to invest in any additional heating plus A/C equipment. The people I was with and I could just have our proper central heating plus A/C idea work for the current family room as well. The people I was with and I had the HVAC duct built and laid within 2 weeks of making the decision and making the iphone call to the local heating plus A/C business. I was pretty ecstatic with the overall results, our family room now has the same wonderful and most powerful heating plus A/C as every one of us do throughout the rest of our home. It helps that every one of us recently bought a brand current and current central heating plus A/C unit.
