GRAND RAPIDS, Mich. – December 10, 2025 – Rua Associates is pleased to announce the successful sale of ProTemp, Inc., of Holland, Mich., to a West Michigan couple. 

ProTemp, founded in 1986, is a commercial and light industrial heating, ventilation, air conditioning and refrigeration business with a nearly 40-year service record of refrigeration repair, equipment replacement, and sales and installation of new equipment. It serves primarily restaurants, bars, grocery stores, gas station/convenience stores, and agricultural operations of all types in the southwestern portion of Michigan’s Lower Peninsula. 

New ProTemp owners Sara and Danny Glemby said they plan to maintain the current staff and add more while building on ProTemp’s track record of quality, honesty and dependability. Their main goal is steady, thoughtful growth – expanding production and capabilities while keeping the close-knit, family-owned feel that makes the Company special. 

Danny Glemby, who has 15 years of experience in the HVAC-R industry, has been a ProTemp employee since 2019. Sara Glemby has extensive experience in administrative roles. 

“Ever since entering the HVAC-R industry in 2010, Danny had aspired to one day own his own company,” Sara Glemby said. “After he began working at ProTemp in 2019, it didn’t take long to see how special this company was.” 

She said the previous owners, Jeff and Karen Koger, “created a great family atmosphere, with strong values, and a great reputation in the community which made it clear that ProTemp was exactly what we had been looking for.” 

“Taking ownership of ProTemp has been such a blessing for our family,” Sara Glemby said. “It’s given us the opportunity to work together toward something meaningful – serving our community while building a future for our children. It also allows us to combine our values, our work ethic, and our faith in a way that we hope will strengthen both our business and our family.” 

The Glembys and Kogers were assisted in the transaction by Rua Associates, a West Michigan mergers and acquisitions company. The Rua team ran a broad process, and ultimately, Jeff and Karen decided that the best buyers to take the company to the next level were Danny and Sara. “We’ve facilitated a number of successful transactions in the mechanical contracting space in the last few years, and the market demand for ProTemp was as strong” said Nick Good, Transaction Advisor for Rua Associates. “Our team’s primary objective in any process is to achieve the expectations of our clients, both from an economic and a legacy perspective. It was fun to see that come together with Danny and Sara.”
