Boosting your building’s energy efficiency isn’t about making one big change—it’s about making the right combination of upgrades that work together. Johnson Construction Company of Aiken, Inc. focuses on practical, long-lasting installations that reduce wasted energy and create more stable interior comfort.
We install energy-efficient windows that keep treated air indoors and block out outside heat and cold.
