Before you upgrade

Check your ducts first.

Thinking about upgrading your heating or cooling system? Leaky or inefficient ducts can cause major energy loss, and that means higher utility bills every month.

Aeroseal is a non-toxic, aerosol-based technology that seals leaks and gaps from inside your ductwork, so heated and cooled air stays where it belongs.

As Pacific Gas and Electric puts it, “It doesn’t make sense to install a new energy-efficient heating or cooling unit unless your duct system is also energy efficient.”
