Anyone who is skilled with their hands likes to think they can tackle just about any type of project around the house themselves. In some cases they’re right. After all, installing a granite top on your kitchen island or track lighting, or wallpaper or tiles in the bathroom are all projects that are well within the abilities of your average do it yourselfer. But the true test of a good DIYer whether in Rapid City, SD, Piedmont, SD or anywhere else isn’t knowing what they can do, but in knowing what they should leave to the professionals, and HVAC work is one of those things. After all, if the bathroom tiles are not square you may have to redo them. But if the furnace or ductwork isn’t installed properly someone could die from carbon monoxide poisoning.
