NAPA — As California building code standards continue to advance, many older homes are falling further behind in terms of energy efficiency, which is why more homeowners are taking a “whole-home” approach to making improvements. Rather than addressing a single aspect (replacing single pane windows with double pane windows, for example), the whole-home approach takes into account multiple areas that affect energy efficiency.
One such area is furnace duct systems. Over time, ductwork can start to deteriorate, whether due to ongoing usage or more active sources such as rodents. Additionally, the duct systems in many California homes can be up to 50 years old—long past their operating lifespans. Since leaky or poorly insulated ductwork can negatively affect furnace efficiency, it’s a good idea to have yours inspected and, if needed, repaired or replaced.
Another important aspect of home energy efficiency is air sealing. While windows represent a major source of air transmission, there are several other conduits for air to enter and exit by, particularly in homes built before modern building code legislation. One example is light switches and circuit plugs that aren’t properly sealed—they can provide a direct channel to an attic or crawlspace and bring cold, unfiltered air into the home. Another example is baseboards, which, even when covered with a piece of trim or molding, can be a surreptitious source of air transmission.
While replacing your windows will certainly have a positive impact, taking a whole-home approach and addressing areas like ductwork and air gaps will enable you to maximize the energy efficiency of your home.
