Seasonal tune-ups that head off the breakdowns.

Maintenance help in Alton
Older equipment can run a long time if somebody keeps an eye on it, and Alton has plenty of equipment worth keeping an eye on. This climate works a system hard at both ends, muggy summers, hard winter freezes, so a spring and fall check earns its keep. We look at what matters, catch small problems while they're cheap, and tell you plainly what can wait. No inspection theater, no scare tactics.
Older equipment is common in Alton, and it's exactly what a seasonal tune-up helps most, weak capacitors, dirty burners, and clogged drain lines are cheap to catch and expensive to ignore. We also find plenty of filters that haven't been touched since the last service call.
Questions from Alton
Cooling in spring, heating in fall, before the season leans on the system. Fall calendars fill up fast once the first cold night hits, so booking early is easier on everyone. A tune-up costs a lot less than the breakdown it heads off.
Call us. Most repair calls get fixed the same day since we stock common parts on the truck, and tune-up customers get priority on the schedule. Tune-ups make breakdowns rarer, but nothing makes them impossible.
What Metro East neighbors say
5.0★ Google · 95+ reviews"We had Dan out to replace our old system. We'd gotten a few other quotes, but once Dan inspected our system we knew the search was over. Knowledgeable, friendly, honest, and he gave us a few options to fit our budget."
"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."
