DEAR BARRY: I don't understand how a home inspector who is not an electrician can evaluate an electrical system; who is not a plumber can evaluate a plumbing system; who is not an HVAC (heating, ventilation and air conditioning) contractor can evaluate a furnace. Can you explain? --John
DEAR JOHN: This is a great question, and there is an analogous question that answers it clearly. How can a family doctor who is not a cardiologist diagnose your heart; who is not an orthopedist determine the condition of your joints; who is not a gastroenterologist evaluate your digestive system?
