Dual Temp

Dual Temp is a leader in mechanical engineering specializing in design, build and service of HVAC/R, Plumbing and Automated Building Control Systems in Eastern Pennsylvania. We are a privately owned, full service mechanical contractor, not a division of any utility company or consolidator, and have been since 1970. Our top leaders are also the shareholders, and come to work here daily. You can expect our personal attention, treating your project or maintenance need as if it were our own. Our value system has persisted over the years, allowing us to survive and prosper through many of the very same outside challenges that have systematically removed many past competitors from the market.
