Furnace Tune-Up & Maintenance in Chicago

The best time to service your furnace is before the first cold snap. ABC's Ultimate Heating System Tune-Up cleans, tests and safety-checks your furnace so it runs efficiently all winter. 

Chicago winters are hard on heating systems. Most no-heat calls we get in January trace back to problems a tune-up would have caught in the fall: a dirty flame sensor, a worn igniter, a clogged filter or a weak capacitor. An annual tune-up finds those issues while they're cheap to fix and before they leave you in the cold.

What's Included in ABC's Furnace Tune-Up

Every Ultimate Heating System Tune-Up includes:

• Cleaning of the furnace and burners so it runs efficiently

• Inspection and replacement of the system air filter

• Flame sensor and igniter inspection

• Safety checks for carbon monoxide leaks, including the heat exchanger and venting

• Air delivery analysis to confirm every room gets proper airflow

• Inspection and lubrication of moving parts

• Electrical connection and control inspection

• Thermostat testing and calibration

• A written report of your furnace's condition and any recommended repairs

Why Annual Furnace Maintenance Pays Off

• Fewer breakdowns. Most failures start as small problems a technician can spot early.

• Lower heating bills. A clean, tuned furnace uses less gas to heat the same home.

• Safer operation. A carbon monoxide check is part of every visit.

• Longer furnace life. Maintained furnaces last longer, which delays a costly replacement.

• Protected warranty. Many manufacturers require annual professional maintenance to keep the warranty valid. Check your paperwork, or ask your technician.

How Much Does a Furnace Tune-Up Cost?

ABC's furnace tune-up can change. Call for current pricing and fall specials. Ultimate Advantage Club members get their heating tune-up included with membership, along with an AC, plumbing and electrical tune-up each year.

The cost is small next to a mid-winter emergency repair, and any problems found during the visit get an upfront, by-the-job price before work begins.

When to Schedule Furnace Maintenance

Schedule your tune-up in late summer or early fall, before you need heat every day. Appointments fill up fast once temperatures drop, so booking early gets you the time slot you want.

Missed the fall window? It's never too late. A mid-season tune-up still improves efficiency and safety for the rest of winter.

Furnace Maintenance FAQs

How often should my furnace be serviced? Once a year, ideally in late summer or fall. Homes with pets, allergies or heavy use may benefit from more frequent filter changes between visits.

Can I maintain my furnace myself? You can and should change your filter regularly. A professional tune-up covers safety checks, combustion and electrical testing that need specialized tools and training.

What's the difference between a tune-up and a cleaning? Cleaning is one step of a tune-up. A full tune-up also includes safety, electrical, airflow and thermostat checks.

Do you service boilers too? Yes. See our boiler maintenance service.
