We’ve been building an in-law suite onto our house for the past several months.
As we were working with the builder, he hired an HVAC contractor to help out with putting in the additional ductwork and air vents and air registers in the addition.
It was confusing to me when they started asking if we wanted to tie in the addition to our existing HVAC system or not. I really have no idea about what makes the most sense when it comes to heating and cooling in my home. The only thing I know is that if I turn the thermostat up in the winter, I want the furnace to come on. And if I turn the thermostat down in the summer, I want the air conditioning to come on and start cooling the house down! So as you can imagine, I didn’t have much of an opinion as to what would be the best way to set up our addition for our heating and cooling system. Apparently, the HVAC contractor thought that we needed to put in a new HVAC unit to support the added load that we would be putting on the system with all of the new space in the addition. And while that made sense to me, I really didn’t want to spend a ton of money on an additional HVAC system! We were already over budget with the addition as it was! We ended up doing what the HVAC contractor suggested, though. He said it would cost even more if we ended up having to do it later once the rest of the work was already done.
