When it comes to home performance, many homeowners blame the heating and air conditioning system when they have a room that is hot in the summer and cold in the winter. The poor HVAC system might have nothing to do with this problem, which might, in fact, be a duct issue, insulation problem, or construction error.
Poor Airflow
Before blaming your hardworking HVAC system for hot or cool spots in your home, check the airflow. In some cases, poor home performance, like hot spots, is actually due to improper airflow. Properly heating or cooling a room requires a certain volume of airflow. Air volume is expressed in cubic feet per minute, and several factors can affect this measurement, including:

- Room size
- Purpose of the room
- Number of windows
- Amount of insulation
- Location within the home
