McElroy Controls springs from a time-tested foundation in mechanical contracting. We understand how building systems work, separately and together – HVAC, energy metering, lighting, industrial controls, backup power and more.

Our wide-ranging expertise and innovative approach help us bring building-controls designs to life through exacting installation skills and craftsmanship. We know how to set systems up for success – whether the designs originated with us, or when working from provided plans.

Count on McElroy Controls to install your building controls to the demanding standards that will ensure optimal function. As needed, we provide UL Listing through McElroy Electric.
