Maintenance help in Granite City

The cheapest furnace repair is the one you catch in October, before the first hard freeze turns it into an emergency. That goes double in Granite City, where a lot of the equipment we see has plenty of winters behind it. A seasonal tune-up catches worn parts early, keeps your system running efficiently, and stretches more life out of a unit you're not ready to replace yet. We do them spring and fall, heating and cooling both.

WHAT WE SEE IN GRANITE CITY

Older systems in Granite City homes will usually give you a warning, a rattle at start-up, longer run times, a creeping utility bill, before they quit. Tune-ups are where we catch that early, while it's still a small fix.

Questions from Granite City

How often should a furnace be serviced?

Once a year, fall for the furnace, spring for the AC. On older equipment it matters more, since one worn part makes the rest work harder.

Do you do furnace and AC tune-ups in Granite City?

Yes, all over Granite City and the rest of the Metro East. We book seven days a week, 8 to 8, so you don't have to burn a vacation day to get on the schedule.

"Dan was fantastic to work with, down to earth, honest, and hardworking. I had a full install done, and as a first-time homeowner he made me feel included and comfortable with all of it."

Phillip Wahby
★★★★★

"Dan was smart, efficient, super helpful, and super reasonable on price. He had my system up and running in a matter of minutes and was at my house the next day. We have a new HVAC guy for life."

Don Myatt
★★★★★

"Dan was extremely responsive. Even though I'm a good distance from his business, he agreed to come out for a very fair travel fee, and he even offered to FaceTime first to help diagnose the problem."
