Furnace Maintenance Spring & Fall Tune-Ups
A furnace that ran fine last winter does not always start fine this winter. Twelve months of dust, spider activity, and minor wear adds up. A pre-season tune-up takes about an hour and dramatically reduces the chance of a no-heat emergency on the first cold night of November.
What we handle
- Full combustion analysis — gas pressure, flame quality, draft, CO levels
- Heat exchanger inspection (visual and with combustion analyzer)
- Blower motor amp draw, bearings, and belt check
- Ignition system service — hot surface igniter, flame sensor, control board
- Filter replacement and a check on filter rack adequacy
- Thermostat calibration verification
- Written report on any concerns — no pressure to fix on the spot
Common signs you might need this
- No professional service in over 12 months
- Furnace was hard to get going at the end of last winter
- You just moved into the home and do not know the maintenance history
- Heating bills climbed last winter without a usage change
- Whistling, banging, or other new noises from the unit

Frequently asked
When should I schedule the tune-up?
Best window is September through October — before peak heating demand. We get booked up by mid-November once the cold snaps start.
Do I really need this every year?
Manufacturers require annual maintenance to keep most parts warranties valid. From a practical standpoint, the carbon monoxide and combustion safety check alone is worth the cost — that is not something you want to skip.
What is included in a tune-up?
Combustion analysis, heat exchanger inspection, blower service, ignition system service, filter replacement, thermostat check, and a written report. About 60 to 90 minutes on most residential systems.
What is the maintenance plan and is it worth it?
Our service membership includes spring AC and fall furnace tune-ups, priority scheduling during peak season, and a discount on any repairs. Most members save more on the discount than they pay for the membership.
