Twenty years ago, Mike Linarez was working construction in Nevada when his company began offering weatherization services. Weatherization makes homes safer, healthier, and more energy efficient by sealing leaks, improving insulation and fixing systems that waste energy or put residents at risk. On the job, he began meeting homeowners whose lives were transformed by lower utility bills. “When you start talking to folks, you realize how much of a difference it makes for them to have those extra dollars each month,” Mike says.
