A primary goal of an HVAC professional is to ensure a customer’s comfort. Let’s say you have designed and installed an HVAC system that is absolutely perfect. The equipment is operating right on the manufacturer’s specifications and sized properly according to load calculations and equipment selection procedures.
Your duct system is installed correctly, free of duct leakage, insulated with the highest R-value insulation you can buy, and is delivering the proper amounts of airflow to each room. Sounds like a great HVAC system, doesn’t it? There’s only one problem: The customer is complaining he isn’t comfortable.
