GMB & Sons Heating & Cooling

GMB & Sons Heating & Cooling is a family owned and operated HVAC contractor based in Livonia, Michigan. With a flawless 5-star rating across 9 verified client reviews, this team has built a reputation for responsive, no-nonsense furnace and air conditioning service throughout Southeast Michigan, including nearby communities such as Dearborn Heights and Farmington Hills. The company maintains weekday hours from 9 AM to 7 PM and weekend availability from 9 AM to 5 PM, ensuring homeowners can reach a live technician when heating or cooling systems fail outside typical business hours.

What distinguishes this contractor is a commitment to high efficiency systems and tankless water heater technology, as demonstrated in a recent full-day installation of a combined boiler and domestic hot water system. Dana Greene's review highlights 24-hour turnaround on an emergency blower motor replacement that other companies estimated would take 7 to 10 days, while Michael Cretu notes the crew completed a large project in a single day. These scenarios illustrate a willingness to tackle urgent jobs without inflated emergency pricing.

James Powers has relied on GMB & Sons for three consecutive system upgrades, including furnace replacement, AC unit swap, and tankless water heater conversion, praising owners Glenn and Eric as experienced, hardworking, and honest. Savannah Midgette experienced a same Thursday-to-Friday turnaround when her combined AC and furnace system failed right before a 90-degree forecast, with the crew completing the repair and thoroughly cleaning the workspace before departure. Ellen Simonetti received a same next-day response after calling late evening during an extreme heat event, underscoring the company's availability when Michigan residents need relief most.
