About Drysdale Energy


Our company was founded as Drysdale & Associates in 1964 by George H. Drysdale.  The company originally sold & serviced infrared temperature measurement sensors as well as vacuum measurement, mass gas flow tools and a variety of related process variable tools. After years of serving as a manufacturer’s representative for industrial instrumentation, Drysdale transitioned into a consulting engineering services provider, offering training in infrared temperature measurement, moisture, spectral analysis, and industrial and commercial energy audits, providing related instrumentation and equipment and expert services, as well as serving as a BPI Gold Accredited Contractor and BPI Training Provider.  Since its founding, Drysdale & Associates has continually added products and services to take advantage of technological breakthroughs to support the energy challenges faced by its customers. As word of its success in solving commercial energy issues spread, demand for its specialty services steadily increased in the residential market.  Drysdale Energy was created in response to the needs of the residential energy efficiency market, and was created to provide a comprehensive approach to home energy efficiency. Our engineering based approach takes advantage of building science principles & advanced testing equipment to solve challenging energy concerns, supported by its fully accredited team of energy efficiency advocates. For the future, Drysdale Energy intends to not only provide industry leading expertise, but will continue to take advantage of scientific approaches to energy efficiency and sustainable approaches to improve residential & commercial buildings.
