What We Check During a Furnace Service Visit
A furnace tune-up from D's Air & Heating covers the components that matter most to safe, efficient operation. Our technicians don't run a cursory visual — they work through the system methodically so nothing gets missed.
Every furnace service visit includes:
- Inspection and cleaning of the heat exchanger
- Burner cleaning and combustion analysis
- Flue and venting inspection for blockages or deterioration
- Filter check and replacement guidance
- Blower motor and belt inspection
- Thermostat calibration and controls check
- Safety switch and limit control testing
- Lubrication of moving components
- Overall system performance assessment
If we find something that needs attention — a worn part, a calibration issue, a safety concern — we'll tell you clearly what it is and what your options are before any additional work is done.
Your furnace works harder than almost any system in your home — and Chicago winters don't leave much room for error. A furnace tune-up once a year is the single most effective thing you can do to avoid a breakdown on the coldest night of the season. At D's Air & Heating, our EPA-certified technicians run through a thorough inspection and service of your system so you head into winter knowing it's ready.
We've been serving Chicago homeowners since 2009, and the pattern we see most often is straightforward: the furnaces that get serviced regularly run longer, break down less, and cost less to operate over time. The ones that don't tend to fail at the worst possible moment.
One Annual Visit Keeps Your Furnace Ready for a Chicago Winter
How Often Should a Furnace Be Serviced?
Once a year is the standard, and fall is the right time to do it. Scheduling furnace maintenance before heating season starts means your system gets inspected while there's still time to address anything that comes up — not after it's already failed on a January night.
Most manufacturers, including Lennox, recommend annual professional service as a condition of maintaining your equipment warranty. As an authorized Lennox dealer, we're qualified to perform that service and document it properly. If your furnace is still under warranty, keeping up with annual service isn't just good practice — it's what keeps that coverage intact.
Maintenance Agreement Members Get 15% Off Every Visit
If you want to stop thinking about whether you've scheduled your annual furnace service, a D's Air & Heating maintenance agreement handles it for you. Members receive priority scheduling — so when the busy season hits and appointment slots fill up fast, you're not waiting — plus 15% off furnace service and related repairs.
For most households, the discount alone offsets a meaningful portion of the service cost. Add in the peace of mind that comes with knowing your system is on a regular schedule, and a maintenance agreement is one of the easier decisions a homeowner can make before winter.

Once per year is the recommended interval for most residential furnaces. Fall is the ideal time — before heating season begins — so any issues can be addressed before you're depending on the system daily. Annual service also satisfies most manufacturer warranty requirements, including Lennox.Once per year is the recommended interval for most residential furnaces.

Dust and debris accumulate on burners and heat exchangers, airflow becomes restricted, and small mechanical issues go undetected until they become larger failures. Skipping maintenance doesn't save money — it defers costs and increases the likelihood of an emergency repair during peak season.Dust and debris accumulate on burners and heat exchangers, airflow becomes restricted, and small mechanical issues go undetected until they become larger failures.

Yes. A clean, properly calibrated furnace runs more efficiently than a neglected one. Dirty burners, restricted airflow, and an out-of-calibration thermostat all force your system to work harder to deliver the same amount of heat — which shows up on your energy bills over the course of a season.Yes.
