Cost to Repair a Furnace in Minnesota
Wondering how much it costs to fix a furnace?
Homeowners in Minnesota pay around $350 on average for a furnace repair. Most pay between $150 and $550, but the price can be as low as $75 or over $2,000 depending on the type of furnace problem and other factors.
In this article, we’ll explain:
- Furnace repair cost factors
- Common furnace repairs in Minnesota
- How you can prevent furnace problems
Let’s start with the factors that determine furnace repair cost.
Furnace repair cost factors
The cost of a furnace repair depends on these factors:
- Service call charge: HVAC contractors charge a standard service call charge fee, which can range from $50 to $200 depending on the company. Sometimes a contractor will waive the fee if they can fix the repair in the same visit.
- Hourly repair rate vs. fixed rate: Every contractor charges differently. Some contractors charge $75 to $150 per hour. Some charge a fixed rate, that is, based on what needs repairing, regardless of how long the repair takes
- Warranties: Some furnace parts are covered under manufacturer's warranty. Also, though less likely, some labor cost could be covered by the HVAC contractor who installed your furnace. You’ll want to contact them to see if anything is covered under warranty.
- Furnace age and condition: If your furnace is old, in a hard-to-reach space or in very poor condition, it is going to be more expensive to repair.
- Replacement parts: Furnace parts cost range from inexpensive (less than $30) like a belt replacement to very expensive like a heat exchanger ($1,000 - $2,000).
- Periods of high demand: During the first freeze or extended cold fronts, service rates can increase because of the high-demand. So if you suspect there’s a problem with your furnace, it’s best to get it taken care of before winter.
Common furnace repairs
Since we repair hundreds of furnaces a year, we’ve noticed these common furnace problems:
- Bad limit switches: If you have a bad limit switch, your furnace’s blower will run constantly, which will shorten the lifespan of the blower. An HVAC technician can quickly fix this problem.
- Faulty ignitions: If you have an electrical problem or a problem with the thermocouple, your furnace is not able to properly heat the home. It could also be potentially dangerous, so make sure to have your HVAC person check your ignition system during your annual furnace inspection.
- Bad thermostat: A thermostat problem can make the temperatures in your home fluctuate. Try replacing the batteries in your thermostat, but if temperatures still fluctuate, contact a heating specialist.
- Flame sensors not working: Flame sensors detect heat from the burners, telling the furnace to continue releasing fuel. If your flame sensors are faulty, your system will shut down or cause fuel to be burned in an unsafe way. That’s a potential hazard for your family, so you’ll want to replace the flame sensors as soon as possible. They cost anywhere from $80 to $250.
- Cracked heat exchanger: A heat exchanger is very costly to fix or replace. It may be worth considering buying a new furnace if that is the case. Learn more about what to do if you think you have a heat exchanger problem.
How to prevent some furnace problems
To prevent serious furnace problems, follow these 3 easy steps:
- Change your furnace filters often: We recommend changing your filters every month during the winter.
- Keep supply vents open (even in rooms your don’t use): Supply vents are the metal grates where heated air is delivered into your home. If you close too many of these vents, air pressure builds up in the duct system, causing the duct system leak more air, which runs up your energy bills. Extra pressure also causes the blower can slow down. And low airflow over the heat exchanger can cause it to crack.
- Schedule an annual inspection: During an annual inspection, an HVAC professional can catch furnace issues before they become serious problems. It’s also essential in to keep your furnace warranty valid.
