If you have ever purchased your own house, you know it can be both thrilling and scary. There are lots of things to think about, and some of those things can cost a pretty penny. The roof is a potential area for problems. The flooring can be a substantial cost if it needs to be changed. The biggest concern most people have, though, is the HVAC system. Nothing can make you more miserable in your home than having inadequate heating and cooling because you just can’t get comfortable in your own space. Most people don’t know anything about air conditioning, though, so they turn to the home inspectors to tell them how the HVAC “looks to them.” I am here to tell you, the typical home inspector doesn’t necessarily know all that much about heating and cooling and the potential hazards or pitfalls. You are better off paying attention to the heating and cooling when you tour the house. Is the cooling the same in every room, or are some rooms much colder than others? If there is uneven cooling, this could be a signal that there is a problem with the a/c. What about the a/c air vents? Put your hand up against them. Is there good air flow through the vents? Is the amount of force pretty much the same at each air vent? Differences could mean blocked ductwork, or worse, broken or cracked ducts. If you notice differences, that is potentially problematic. Is the HVAC system just plain old? Most people can tell you how old the a/c is; if they can’t remember, an a/c technician can find a model number and possibly the year it was manufactured.
