Four Walls Home Energy Efficiency performs energy audits on existing homes, including diagnostic testing. We are an integrated company, using the audit as a basis for creating and implementing a weatherization proposal. This allows us to take full advantage of the audit findings to very effectively improve the comfort level and energy efficiency of your home, both summer and winter.
Our audits and evaluations are backed by over 40 years of hands on experience in residential construction. We can consult with designers and architects on plans for both remodels and new homes. We also offer PTCS heat pump commissioning and duct testing in partnership with selected HVAC contractors.
We are thorough, friendly, trusted and effective. We work in the Portland-Salem area, as well as McMinnville, and on request will accept projects in Black Butte, the coast north of Newport and elsewhere in Western Oregon. We are a top rated Energy Trust Trade Ally and a McMinnville Water and Light Recommended Contractor.
We are also Third Party Verifiers and Building Performance Specialists for the Northwest Energy Star New Home program, registered in both Oregon and Washington. In this capacity we work closely with builders, owners, architects and designers to maximize energy efficiency in new homes while minimizing the investment.
Any questions or inquiries, please call us directly at 503-547-7139 or by email at email@example.com. Looking forward to hearing from you.
