The $105 Tune-Up Scope

What's Included in a $105 Furnace Tune-Up

Details below
An inspection, measurement, or cleaning item below doesn't automatically include a replacement part, and flame-sensor and burner cleaning are only done when necessary. Anything beyond this scope, a failed part, for example, is priced and explained before we do the work. You'll also get an emailed copy of the completed checklist after the visit.

Thermostat and Controls

Heating mode and fan settings, temperature setting, programming, batteries where applicable, and calibration.

Air Filter and Blower

Inspect the air filter and blower wheel, inspect the blower motor including checking for oil residue, inspect the blower motor capacitor where applicable and measure motor capacitance, and measure blower motor amperage.

Ignition, Burners, and Heat Exchanger

Inspect and clean the flame sensor, inspect the igniter, inspect burner operation and verify the flame pattern, clean burners when necessary, and inspect the heat exchanger for cracks, damage, or other defects.

Gas Supply and Venting

Inspect gas piping for leaks, check gas pressure and adjust if necessary, and inspect the flue pipe and venting system, including intake and exhaust piping where applicable.

Condensate Drainage

Inspect condensate drain tubing and lines, including drainage on high-efficiency furnaces, and inspect the condensate pump where applicable.

Electrical Components and Safety Controls

Inspect wiring connections and the control board, inspect and test applicable safety switches including safety limit switches, and test overall furnace operation and safety controls.

Operating Readings and Performance

Record the return-air and supply-air temperatures and the temperature rise between them, record a carbon monoxide reading in parts per million, and check for abnormal sounds and vibrations.

Furnace Tune-Up Cost: $105

The standard furnace tune-up is a flat $105, and that covers the full inspection, cleaning, and testing scope above. The price doesn't change based on brand or age, so you don't need a custom estimate just to find out what a tune-up costs. If the technician finds a part that needs repair or replacement during the visit, a failing capacitor or a cracked heat exchanger, for example, that work is priced and explained separately, and nothing beyond the tune-up happens without your approval.

Why Annual Maintenance Is Worth It

Regular maintenance gives a technician the chance to catch a developing problem, a dirty flame sensor, a weak capacitor, early heat-exchanger damage, while it's still something to monitor instead of a no-heat call in the middle of winter. It doesn't guarantee your furnace won't break down, and it isn't a substitute for repairing a part that's already failed, but a furnace that's inspected and tested annually tends to run the way it's supposed to more consistently than one that isn't. Changing the air filter every 1 to 3 months is something you can do yourself between visits. The rest of the list above is worth having a technician handle once a year.

The Right Time to Schedule Your Tune-Up

September or early October, before the first real cold snap, is the easiest time to get a tune-up on the schedule. That said, if it's already winter and your furnace hasn't been serviced in a couple of years, it's still worth booking rather than waiting for next fall. We serve Watertown and surrounding areas, including Delano, Waconia, and St. Bonifacius. You're welcome to book online or call or text (952) 847-3387, whichever is easier.

If your system includes more than a furnace, a humidifier, air exchanger, or zone system, for example, our HVAC maintenance program covers those services together, with its own program pricing and benefits.

FAQ Common questions

Frequently Asked Questions

Answers below
Is a furnace tune-up the same as a furnace safety check or inspection? +
Yes. Some homeowners call this a furnace safety check, others call it a furnace inspection, and we call it a tune-up, but it's the same $105 appointment: a safety and operating check of the thermostat, burners, heat exchanger, venting, and electrical controls, plus cleaning where it's needed. Whatever you call it, the scope and price are the same.
What does a furnace tune-up include? +
The $105 tune-up covers the thermostat and controls, the air filter and blower, ignition and burners, the heat exchanger, gas supply and venting, condensate drainage, and the electrical and safety controls, plus a set of operating readings like temperature rise and a carbon monoxide check. It's an inspection, cleaning, and testing scope, not a parts-replacement visit: if something needs repair or replacement, that's priced separately and explained before we do the work.
How long does a furnace tune-up take? +
Most appointments take about 30 to 120 minutes. The exact time depends on the furnace's age, condition, and how accessible it is, a furnace that's been well maintained generally goes faster than one that hasn't been serviced in a few years.
What happens if my furnace needs a repair during the tune-up? +
The technician explains what was found in plain language, what it means, and what it costs to fix, before any repair work happens. You decide whether to move forward. There's no pressure and no surprise charge added to the $105 tune-up. For more on how we handle repairs specifically, see our furnace repair page.
Do I get a record of what was checked? +
Yes. After the appointment, you'll receive an email with the completed technician checklist, showing what was checked and what was found. It's a written record you can keep, not just a verbal summary.
How do I know if my furnace filter needs to be changed? +
Pull it out and hold it up to a light. If you can't see light through it, it's overdue. Most 1-inch filters need changing every 4 to 6 weeks during heavy heating season. Thicker media filters, 4 to 5 inches, can last 6 to 12 months. A clogged filter restricts airflow and forces the blower to work harder than it's designed to. It's the easiest maintenance item on the list, and it's the one most people forget.
Can a furnace tune-up improve my energy bill? +
It can help. A dirty burner or a clogged filter makes the system work harder to produce the same amount of heat, and a tune-up addresses both. How much that shows up on a given bill depends on the furnace's age, condition, and how long it's gone between services, so we can't promise a specific number, but keeping the system clean and properly adjusted is one of the more practical things you can do.
