The Cost Ranges Of Common Furnace Repairs

Your home’s heating equipment is beyond doubt, one of the biggest investments you have. When something goes wrong with, say your gas or electric furnace at one point or another it needs to be repaired as soon as possible to ensure they work efficiently and continue providing your home with the comfort it deserves. Proper knowledge for the cost of repairing different parts of a furnace may help plan a budget to help at the expense of fixing a damaged furnace.

A furnace contains many and different parts hence it is difficult to exactly pinpoint the average cost of repairing the heating implement. In some cases, some parts need more attention and servicing compared to others. Below are some of the parts that frequently need repairs, just to give you a rough idea on the cost of furnace repair.

Flame Sensors and Igniters

Statistics show that on average, eighty percent of repairs are due to bad igniters. Most replacements occur on emergency service pushing the price of igniters to three hundred to four hundred dollars plus an additional fee for after hours. If new igniters are replaced on routine service, they may cost half only. Igniters can be kept clean on a regular maintenance. If they become extremely dirty and are not cleaned on time, they can cause a lot of unwanted issues. Failure of igniters can cause the circuit board to short out creating more problems. Flame sensors malfunction often when they become dirty. Unlike igniters,                                                                                           flame sensors return to normal once they are cleaned thoroughly.


The thermostat may stop working due to various reasons. Some of the common causes may include faulty wiring or the thermostat calibration is not correct. Still, a thermostat may blow a fuse or trips its circuit breaker. On a cost perspective, it is cheaper and easier to replace a thermostat compared to other furnace parts. A basic non-programmable model ranges from as low as $200-$300 installed, while more advanced thermostats prices range from $400 to over $1,000.

Blower Motors

Every air system in a home, electric or gas-powered, has to use a blower motor. The blower motor comprises a fan and electric motor. The work of the fan is to circulate air evenly in the fan. When a blower motor stops working, hot air needed to warm the house will not be distributed evenly in the furnace leading to repairs. Depending on the damage to the blower motor, repair prices range from a low of $350 for removal and cleaning of the blower up to as much as $2,000 to replace the motor, depending on the type of furnace and which furnace brand you have.

Heat Exchangers

A heat exchanger main work is to heat air pushed by the blower motor via the furnace. Main components of a heat exchanger include a chamber where heat energy from propane gases or natural gases is mixed with forced air. A vent is also a component of a heat exchanger where gases are safely removed from its unit and this air enters the home. These gases can cause problems to the inhibitors of the home and this problem has to be dealt with fast. When dealing with potential heat exchanger problems, it’s critical to find a reputable furnace repair service company to do a thorough inspection of the unit.

Problems with the heat exchanger can cause leaks of carbon monoxide which is fatal if inhaled. The cost of repairing a heat exchanger varies and may cost as low as $2,000, but whenever possible you should replace the furnace instead of repairing the heat exchanger.
