Energy-Efficient Heating and Cooling Equipment

A high-performance and properly-sized heating and cooling system is an important feature of a high-performance home. HERS Raters work with high-performance homebuilders to ensure the proper sizing of your heating, ventilating, and air conditioning (HVAC) system. Bigger is not always better with HVAC equipment. Your house may not require a big unit because the home is energy-efficient.

 
Benefits of Properly Sized HVAC Systems: Properly sized systems require less maintenance and last longer. This is especially important for your air conditioner (cooling) units, where a properly sized system works much more efficiently and helps to control humidity better.  By combining an energy-efficient HVAC system with appropriate insulation, air sealing, and windows, you can reduce your energy bills, increase the durability of your HVAC equipment, and reduce the greenhouse gases in the air we breathe.
