The improvement of this house was remarkable. The electric bill was reduced to ½ compared to an equivalent period of time before applying the improvements. Now the house is comfortable in every corner due to a balanced air distribution system, with air returns in each bedroom, even the room under vaulted ceiling shows the same comfort than any other place of the house.
