Efficiency tips for manufactured homes 

More than 22 million Americans live in manufactured homes, according to the National Association of State Energy Officials. Manufactured homes represent 15% of housing in rural areas, and only 3% in urban areas. 

ENERGY STAR-certified manufactured homes are 30% more energy efficient than standard models, with a variety of options that increase the home’s energy efficiency. 

If you already live in a manufactured home, you likely know they are constructed in sections. One section is a single wide home, two are combined to make a double wide home and three make a triple wide home. 

Check the ductwork 

Typically, the biggest issues are in the duct systems, which deliver heating and cooling throughout the home. The ductwork is usually in the cavity between the floor and the transport barrier, which protects the underside of the home while it is transported from a factory to the site for setup. Typically, one long duct runs the length of each section, with the registers or vents cut into it. 

First, make sure all registers are accessible, open and not covered by furniture, rugs, dog beds or anything else. 

Next, check your ductwork by removing the registers and looking inside. Anything inside will restrict airflow, so check that it is clear. Use a mirror and flashlight to look in the duct or take a picture by sticking a camera or phone inside and snapping some shots with flash in each direction. 

If you have a double wide or triple wide, you likely have a crossover duct, which joins the ducts in each section. Damaged or disconnected crossover ducts allow the air you pay to heat to escape under the home. An inspection of the crossover duct requires crawling under the home. That’s a dirty job and often a tight spot, so you might choose to hire a professional.

Caulk and insulation

Another place to check in your manufactured home is the joint connecting the sections together. This is often covered by trim when the home is placed. You can caulk around the trim or remove it and caulk underneath to reduce air leakage. 

Weatherstripping doors and windows to make sure they seal tightly will also reduce drafts and save energy. Some homes can benefit from additional insulation in the attic or under the floor. Those projects typically require specialized equipment or help from a professional.
