Avoid Oversizing Your HVAC System

My friend has been having a tough time buying a house.

She is too picky with her decision.

I told her at this point she needs to write the houses she wants the most on a card and put it in a hat. She told me it is a serious decision (which I do agree) but she has becoming very indecisive with this whole process. After a week of deciding she finally made her pick. She chose a smaller house off of a side street. She got a very good deal on it however there were some things that she needed to buy and update. I got a call from her the other day. She told me that she had an appointment with an HVAC technician. He told her that she definitely needed a replacement with her HVAC system. She was a little upset hearing this because it would cost her a few thousand dollars. She told me that the first thing that the technician did was do a manual and commercial load calculation. This would allow my friend to have the proper size for her new HVAC system. If this calculation didn’t occur, she could have the wrong HVAC system size. If a unit is oversized and is too big for a home, it can increase the capital cost at the time of installation and extra costs to when the HVAC system runs. I was curious to know all of this because I didn’t realize that an HVAC system had to be sized. Now I know for when I own my home someday.
