What a Full Tune-Up Actually Covers
There's a lot of variation in what HVAC companies call a "tune-up". Some show up, change the filter, and hand you a bill. We don't do that. Here's what a Full Time maintenance visit includes:
- Combustion analysis to verify the burner is burning clean and efficiently - Heat exchanger inspection for cracks that can allow carbon monoxide into living space - Burner cleaning and flame sensor test - Flue pipe and draft test to confirm exhaust is venting properly - Blower motor amp draw check and belt inspection if applicable - Electrical connection tightening on contactors, terminals, and control boards - Limit switch and safety control verification - Filter inspection and replacement recommendation - Full carbon monoxide safety check
If we find something during the inspection, we tell you what it is in plain language before we touch anything. You decide what to do next. That's how it should work.

Why Skipping Annual Service Costs More
We hear it every season. A homeowner put off the tune-up, the furnace ran fine all fall, and then December hits and the heat exchanger finally cracks or the inducer motor seizes. Now it's an emergency heating repair call in the middle of a cold snap instead of a scheduled maintenance visit in October. Emergency calls cost more. Parts take longer to source in peak season. And if the heat exchanger has been cracked for months, you've been running a carbon monoxide risk the whole time without knowing it.
A dirty furnace filter alone can increase your energy bill by 15 percent or more. It also overworks the blower motor and shortens the life of the heat exchanger. Changing the filter every 1 to 3 months is something you can do yourself. Everything else on the list above is worth having a technician handle once a year. It's not upselling. It's just how furnaces work.

What Drives the Cost of a Furnace Tune-Up
Most homeowners across the Twin Cities metro pay somewhere between $80 and $250 for a furnace tune-up, depending on system age, manufacturer, and what's actually needed. An older, single-stage furnace that hasn't been serviced in three years is going to take longer than a two-year-old variable-speed unit that was maintained last fall. If we find a part that needs cleaning or adjustment during the visit, we let you know the cost before we proceed.
We don't bundle maintenance into high-pressure service plans. If a plan makes sense for your situation, we'll tell you. If it doesn't, we won't pitch it. Every job is different. Contact Full Time Heating and Cooling for an accurate estimate. You can also reach us at (952) 847-3387 if you want to talk through what your system might need before booking.

The Right Time to Schedule Your Tune-Up
The short answer is September or early October, before the first cold snap. We get backed up fast once temperatures drop below freezing and the calls shift from tune-ups to no-heat repairs. Schedule in the fall and you get a faster appointment, a less stressed technician, and any needed parts ordered before they're back-ordered.
That said, if it's January and you haven't had your furnace serviced in two or three years, schedule it now anyway. A winter tune-up is still better than no tune-up. We serve homeowners throughout the Southwest Metro including Chaska, Rockford, and surrounding communities. If you're unsure whether your furnace is due, a quick call tells us more than a form ever will.
We also handle thermostat upgrades during maintenance visits if your current stat is giving you trouble. And if your home runs dry in winter, ask about humidifier installation and service. It's a natural add-on when we're already in the mechanical room.

FAQ Common questions
Frequently Asked Questions
Answers below
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, overheats the heat exchanger, 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? +
Yes, in a real and measurable way. A dirty burner runs at lower combustion efficiency. A clogged filter makes the blower run longer to move the same amount of heat. Worn contacts and failing capacitors cause the system to cycle inefficiently. A full tune-up addresses all of those. Over a full heating season the difference in runtime efficiency adds up. For older systems in poor condition, the savings can be significant.
How much should a new furnace cost? +
A furnace replacement in the Twin Cities metro is priced by the efficiency rating (80% AFUE vs. 96% AFUE), the size of your home, whether any ductwork modifications are needed, and which brand and model you choose. High-efficiency variable-speed systems cost more upfront but recover some of that difference in monthly heating bills. Every job is different. Contact Full Time Heating and Cooling for an accurate estimate before you commit to anything.
What is a furnace? +
A furnace is a forced-air heating system that burns natural gas, propane, or oil to produce heat, then distributes that heat through your home's ductwork via a blower motor. Most Minnesota homes run gas furnaces. The key components are the burners, heat exchanger, blower motor, control board, and flue system. During annual maintenance, each of those components gets checked, cleaned, and tested so the system runs safely and efficiently through the heating season.
Which brand of furnace is the most reliable? +
Honestly, brand matters less than installation quality and how consistently the system gets maintained. A well-installed, well-maintained mid-tier furnace will outlast a premium brand that was rushed in and never serviced. Full Time is an AirQuest Elite Dealer, and we recommend AirQuest equipment partly because it delivers dependable performance without the brand-name markup. Qualifying AirQuest installations also include a No Hassle Replacement warranty, plus two additional years of coverage through Full Time's Elite Dealer status.
What is better, a heat pump or a furnace? +
In Minnesota, the honest answer is: it depends. Heat pumps are highly efficient down to about 0 to -5 degrees Fahrenheit, but they struggle in extended deep-cold stretches. A dual-fuel system that pairs a heat pump with a gas furnace as backup gets you the best of both for Minnesota winters. Straight gas furnaces are still the practical choice for many homes here, especially older construction with existing ductwork. We'll tell you what actually makes sense for your situation, not what generates the bigger ticket.
