How does your home and HVAC system perform?

Most California homes are leaky, improperly insulated, and have terrible HVAC systems. Your home is gaining too much heat in the summer and losing too much in the winter because it isn’t properly air-sealed or insulated. The HVAC system is oversized, with ducts that are too small and very leaky. You should expect more from your home and its HVAC system.
