Call to Claim the $49 Furnace Tune-Up Fall Special · Residential homes · Price is per furnace · Offer ends 11/15 · *Guarantee requires completing any recommended repairs · Offer detailsABC's Ultimate Tune-Up is a 360-degree evaluation of your home's heating system, focusing on your furnace and all of its components. A trained technician performs a thorough clean and check — a genuine multi-point service, not a quick look — so your furnace runs efficiently and safely all winter. Here's what's actually done:
The one that matters most. A cracked heat exchanger can leak carbon monoxide into your home, so your technician inspects it closely before anything else.
Burners are cleaned and the flame is inspected. A dirty burner or a yellow, lazy flame means incomplete combustion — wasted gas and a safety concern.
We test combustion and inspect the flue and venting for blockages, corrosion or leaks, so exhaust goes outside your home instead of into it.
Limit switches, the flame sensor and safety controls are tested, and gas pressure and connections are checked for leaks and correct operation.
Connections are tightened, amp draw is measured on the motors, and the thermostat is checked for correct calibration and cycling.
The blower is inspected and moving parts lubricated, then we measure temperature rise and airflow to confirm the furnace is heating efficiently, not straining.
From tune-ups to full system replacements, ABC keeps Chicagoland homes comfortable — whatever the temperature outside.

Fast diagnosis and repair on any make or model — often same day, so your home is comfortable again quickly.

"Jose Patino gave me excellent service. He walked through everything he was doing and even offered to come back the next day to ensure everything was working proper. This guy is an amazing technician. Highly recommend!"
"Carlos is wonderful! He is very knowledgeable and detailed and explained our unit's issues and any corrective actions moving forward. Highly recommend!"
"Ricardo and Ruben were FABULOUS. Ricardo talked me through the entire process and provided detailed explanations for someone who is far from expert. I'd avoided A/C service for years after a bad experience with another company — now my faith is restored thanks to these two."
"Luis L was wonderful. Very knowledgeable and helpful with the process of getting our new system!"
"Richard was great. He was on time and very friendly and knowledgeable about everything. He provided thorough explanations about every service he would be performing today."
"Nico was very knowledgeable and did a good job on explaining everything in detail."
