2 System replacement - Questions from a newbie homeowner
New homeowner here looking to replace 2 units, 1st time HVAC customer (feeling a little in over my head). I love to learn and read, Can someone direct me to a new system purchasing checklist or an FAQ's page that I can use to help navigate this process of finding a reputable HVAC company, and how to choose what systems we should be considering. I am thinkning that this is going to be a $-$$ job and I want to do my part to make the right choices in contractor and system for my home (not just take someones word for it). Thank you in advance Guys!
