Cortec Group, a private equity firm, completed the investment in Four Seasons Heating & Air Conditioning, a mechanical contractor. Financial terms were not disclosed. “Dave and his team have achieved tremendous growth, all organically, by consistently providing high-quality service and value to their customers. Our familiarity and success with residential services businesses, including our investments in Window Nation, Groundworks and Goettl, allowed us to appreciate the strength of Four Seasons’ brand and growth potential. We’re excited about what the future holds for this partnership,” Doug Kruep, Cortec Partner.
