This video shows the kind of effect poor duct design has on airflow. It also shows what dirty or highly restrictive air-filters do to conditioned air. Just think, the slower the air moves the longer it takes your system to satisfy the thermostat. This eqautes to higher operating expenses (your energy bill) due to longer run time.
These videos will allow you to understand the importance of maintaining your hvac equipment and the negative effects of a neglected heating/air-conditioning system. Learn such things as, what does a dirty evaporator coil look like and how does it happen? How does a restrictive filter affect my efficiency? And, what happens to a compressor on neglected systems?
Here are some videos displaying the operations of properly and improperly performing distribution systems. Note: A distribution system is that part of the system in which the heat is delivered into the conditioned space for the occupants.
Learn what effects a poorly installed unit has on manufacturer's rated efficiency. See what happens to room comfort, your energy cost and equipment performance. Pay close attention to the difference in equipment performance between a good and bad installation.
