Pre-Winter Furnace Tune-Ups Done the Right Way
A real furnace tune-up is part inspection, part safety check. Skipping it doesn't save money — it just trades a $150 service call for a $400 emergency repair on the coldest night of the year, or worse, a CO scare you don't want.
What an Honest Furnace Tune-Up Includes
A full BakerHouse furnace tune-up covers safety, efficiency, and reliability — in that order. We're looking for what could fail this winter, what could become a safety issue, and what could be running better than it is.
- Combustion analysis — actually measuring CO, O₂, and flue temperature, not just eyeballing the flame
- Heat exchanger inspection — visual and instrumented check for cracks (this is the safety one)
- Burner cleaning and inspection — soot, alignment, flame pattern
- Ignitor and flame sensor check — ohms reading on the ignitor, cleaning the flame sensor
- Gas pressure verification — measuring incoming and manifold pressure, adjusting to spec
- Pressure switch and limit switch testing — the safeties that keep you safe
- Blower motor amperage — comparing draw to nameplate to catch worn bearings
- Filter replacement — and a real conversation about the right filter for your system
- Thermostat calibration — verifying the temperature it's reading matches reality
- Venting inspection — checking for blockage, draft, condensate flow on high-efficiency units
Why Pre-Winter Maintenance Matters in New Mexico
Cold snaps in Albuquerque metro and the East Mountains hit hard and fast — sometimes 70°F in the afternoon, 18°F by morning. A furnace that's been sitting unused since March will reveal every weak component within the first 48 hours of cold weather. Maintenance in October catches the marginal ignitor, the soot-clogged burner, the slow gas leak before they leave you in the cold.
Carbon Monoxide Safety
Combustion analysis isn't a luxury checklist item — it's the only way to actually verify your furnace isn't producing dangerous levels of CO. We measure it on every tune-up and won't leave a unit operating outside safe combustion parameters. If you don't have working CO detectors in your home, mention it during your appointment.
Maintenance Plans
For homeowners who want it handled, simple seasonal plans cover spring AC tune-up plus fall furnace tune-up, priority scheduling, and reduced labor rates. Ask about it during your call.

Common Questions, Straight Answers
When should I schedule my furnace tune-up?
Mid-September through November is ideal — early enough to get on the schedule without rushing, late enough that any repairs we recommend will be tested when it gets cold. Don't wait until the first cold snap; that's when the no-heat calls fill the schedule.
How much does a furnace tune-up cost?
Standard residential tune-ups are flat-rate and we confirm the price when you schedule. Maintenance plan members get a discount plus priority scheduling.
Do I need a tune-up every year?
Yes. Combustion drift, soot buildup, and component wear happen gradually. The point of annual maintenance is to catch the changes before they become failures or safety issues. The tune-up cost pays for itself the first time it catches a $20 part before it strands you.
What if my furnace is working fine?
That's the goal — and the time to catch the components that are about to fail is while everything still works. Combustion analysis and heat exchanger inspection are not visible to you; they require instruments to verify.
Should I be worried about carbon monoxide?
Healthy furnaces in good repair produce minimal CO. Cracked heat exchangers, soot-clogged burners, or improperly drafting flues can produce dangerous levels. We measure on every tune-up call. If you don't already have CO detectors on every floor, install them.
