For more than one hundred years, Hooper Corporation has been your full-service electric power and mechanical contractor. We are proud of what we have built and those we have partnered with.

Since 1913, Hooper has focused on building strong, long-standing relationships to connect people to the resources they need, from heating and cooling to plumbing and electric power. You may not see our work behind the drywall or buried underground, but our reputation for honest, high quality work has earned the respect of our contracting partners, customers and clients. Our employees are dedicated to providing outstanding craftsmanship, rising to the challenge, and ensuring safety both on and off the job site.

Strong growth over the last decade has recently propelled our expansion into a new headquarters and fabrication facility in DeForest, Wisconsin. Hooper and its long-time subsidiary, General Heating and Air Conditioning, are now joined together as one company, under one name, and on a state-of-the-art campus. Electric power, plumbing, HVAC, fire protection, process piping, custom metals and sheet metal fabrication are unified to better serve our clients and community.
