Robert M. Silverlake, CA
I bought my silver lake home in 1996. It had an old furnace and wall ducts with some insulation. No central air. As the years passed and the climate changed my home became less and less comfortable.

For some years we had been paying through the nose to heat our home in the winter, and finding it impossible to cool our home in the summer.
