Professional Heating Solutions For Your Home & Business
From furnace breakdowns on Saturday night to high-efficiency system upgrades, Hollister keeps Western Illinois warm.
80 Years of Heating Macomb & Western Illinois
Our grandparents started this business in 1944, right here in Macomb. Back then, most homes had coal furnaces. Now we install high-efficiency heat pumps and smart thermostats. But one thing hasn't changed—when your heat goes out, we show up. Same day if you need us. Middle of the night if that's when it happens.
