Too hot? Too cold?

Heating matters a lot. According to the US Department of Energy, space heating is the largest energy expense in the average US home, accounting for about 45% of energy bills. When it comes to efficiency, it's important to consider not just the efficiency rating of your furnace, but also proper sizing. Putting in an over-sized furnace will reduce the efficiency, comfort and indoor air quality in your home. 

Heat Pumps

During the heating season, heat pumps move heat from the cool outdoors into your warm house, and during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can provide equivalent space conditioning at as little as one quarter of the cost of operating conventional heating or cooling appliances. 

Air Conditioners

Air conditioning is becoming a necessity in the Pacific Northwest: 15 of the 16 hottest years on record have occurred since 2001. The warming will continue, but you can stay cool without breaking the bank. The US Department of Energy estimates that homeowners can reduce cooling costs by 20-50% by switching to a high-efficiency air conditioner and taking other actions to keep costs down. 





According to the US Department of Energy, single-pane windows are impractical in heating-dominated climates like the Pacific Northwest. "Multiple-pane, low-E, and gas-filled window configurations are advisable."

Attic Insulation

“One of the most cost-effective ways to make your home more comfortable year-round is to add insulation to your attic.”
- US Department of Energy

Wall Insulation

Wall insulation is the single biggest opportunity you have to increase comfort and save energy in your home. In a home without wall insulation, about 35% of heat loss occurs through wall cavities.

For a typical crawlspace, the best approach is to completely fill each cavity with fiberglass batts. The batts must be properly secured to the floor joists so that they do not droop or fall. Any air gaps significantly diminish the effectiveness of the insulation. 

In addition to insulating your crawlspace, it is critical to install a vapor barrier for moisture control and indoor air quality.
