Founded in 1951 by Truman and Evelyn McCarty, McCarty's Heating & Welding has served the Greater Grand Forks area for over 70 years. What began as a small boat engine and plumbing service soon evolved into a reputable heating, welding, and boiler repair company. The business grew rapidly through the decades, taking on major industrial and municipal projects such as the Simplot plant remodel and water tower welding at the Grand Forks Air Force Base.

In 2015, the company expanded its offerings with the creation of Mac’s Pool Pros, specializing in swimming pool and hot tub services for residential and commercial clients. Led by CEO Mike McCarty and COO Connor McCarty, the business remains family-operated and committed to delivering top-tier customer service and professional results. Mac’s Pool Pros is now a trusted name in the region for pool care, continuing the McCarty tradition of excellence with plans for future growth and innovation.
