Without adequate duct insulation, there can be significant heat loss or heat gain as conditioned air travels through the comfort delivery system. This is especially true where ducts are located in an uninsulated attic or crawlspace. Insulation significantly reduces this energy loss and helps ensure...

Air needs to flow from the central heating and cooling comfort system to living spaces and back again. Comfort crossover vents allow air to flow from each bedroom to the central return ducts, often located in hallways. The vents are typically built into the ceiling on either side of the adjoining...

Conditioned air is often lost in transition from comfort equipment to living spaces because of poorly designed duct layouts and poor installation practices, which cause homeowners to pay for conditioned air that never reaches the living spaces of their home. Poor duct layouts with overly long duct...

As conditioned air flows through the ducts from heating and cooling equipment to the spaces where people live, excessive length, sharp bends, crimps, and crushed or disconnected ducts can compromise air flow, reducing comfort and causing the HVAC system to work harder than necessary. Professionally...

Comfort systems installed in vented attics work much better when they are buried in insulation. Vented attics can reach extreme temperatures. Deeply burying the ducts in the attic's insulation provides significant protection from these harsh conditions. The ducts need to be tightly sealed to ensure...

Traditional vented attics can reach extreme temperatures compared to living spaces and are inhospitable to heating and cooling equipment and ducts. Comfort systems work much better when they are inside conditioned space. That’s why unvented attics that are fully insulated provide a more efficient...

In addition to the savings that come with being an efficient heat pump, ductless heat pumps save energy and money by avoiding the use of ducts or using much more compact duct layouts inside the conditioned space. That’s because ducts are often sources of heat loss where not properly insulated and...

A home energy rater will conduct an in-depth energy performance assessment of a home using diagnostic testing equipment, such as a blower door test, a duct leakage tester, a combustion analyzer, and infrared camera to determine the amount and location of air leaks in the building envelope, the...

Poorly air-sealed homes are less comfortable and cost more to maintain because they provide a pathway for drafts, cold spots, moisture, and insects into the home. Comprehensive draft protection includes a continuous air barrier around the whole house along with caulking and sealing in all holes and...
