Gross Heating & Air Conditioning

Gross Heating & Air Conditioning has kept Brookfield and Menomonee Falls homes comfortable since 1925, making it nearly a century of continuous operation in southeastern Wisconsin. The company holds Carrier Factory Authorized Dealer status, backed by NATE-certified technicians and recognition as a 2026 President Award recipient. With 383 reviews averaging 4.9 stars and 24/7 emergency availability, the company serves residential and commercial customers across the greater Brookfield area. Their location at 3260 N. 126th St. positions them to respond quickly to calls from surrounding neighborhoods.

What distinguishes Gross Heating is their exclusive partnership with Carrier and their commitment to factory-authorized expertise. As a distinguished Carrier dealer, they install and service the full line of Carrier Infinity, performance, and comfort systems with manufacturer-backed warranties. The company offers financing options for new system purchases, making equipment replacement more accessible. Their maintenance agreement program provides priority scheduling, 15% parts discounts, and reminders for seasonal tune-ups, helping homeowners avoid unexpected breakdowns and potentially reduce energy costs by 10-30%.

Customer reviews reveal the human side of this multigenerational business. One reviewer described technician John G as a superstar who diagnosed and repaired their furnace quickly on the coldest day in years. Another specifically requests Randy for any furnace work, praising his thorough explanations of every step and his dedication to confirming everything works properly before leaving. Co-owner Jerry personally installed a Carrier Infinity furnace for a customer the same day they called, while his wife Cari handled scheduling with responsiveness and care. These named technicians reflect the company's investment in long-term employees who treat customers like family.
