Furnace Repair & Heating in Collinsville
Furnaces, heat pumps, and fast repairs, so nobody rides out a cold night.

Heating help in Collinsville
A furnace that quits during a January cold snap is not something to sit on. We're DMAK'S HVAC, a family-owned shop based just up the road in Edwardsville, and we handle furnace and heat pump repairs for homeowners across Collinsville. Most repair calls get done the same day because we stock the common parts on the truck, and when you call you get Dan, not a call center.
Around the older parts of Collinsville we see plenty of furnaces running well past their expected life, and houses that have been added onto over the years often have ductwork that never kept up. Both are fixable without starting from scratch.
Questions from Collinsville
Usually the same day. Our hours run seven days a week, 8am to 8pm, and Collinsville is a short trip from our Edwardsville shop. Most heating repairs get finished in one visit because we keep common furnace parts stocked on the truck.
It depends on the age of the unit and what failed. We give you an honest read and a free quote either way, and we don't push new equipment when a repair will hold. If replacement makes sense, we walk you through options sized for your house, with financing available.
What Metro East neighbors say
5.0★ Google · 95+ reviews"Our coil went out right as it got hot out. Another large company tried to give me the runaround, so I called DMAK for a second opinion. They were quick to show, gave a fair price, and replaced the coil same day."
"Dan came soon after I called. Our furnace was old and not working and it was freezing. He installed a new furnace as fast as possible, his price was fair, and he fixed a problem with our air conditioner while he was here."
"Dan came to my house and set up my new unit, and he was very kind and informative about his procedures. He got the job done and kept us protected from the heat. I'll use his services again for sure."
