Furnaces are necessary for any household that experiences extreme winter conditions, depending on its geographic location. If your furnace is not working properly, then the first thing to do is call an HVAC technician who is experienced in handling these problems. There are a lot of DIY enthusiast homeowners who prefer to repair furnaces on their own, but furnace companies strictly disapprove of this. Experts can repair faults quickly and provide you with tips that will help maintain the furnace’s condition over time.

The gas valve is considered the heart of the machine as it controls the amount of fuel fed into the furnace. This valve can open or close periodically to control the fuel input. However, this is a small component and can be easily damaged if not maintained properly. Two different types of valves are commonly used in a furnace, namely the chain valves and the combination valves. The pilot light in a gas valve should always be on; if it is not on, it has to light externally. An average furnace runs for around 20 years, so knowing such troubleshooting methods can come in handy.

The repairing cost of a furnace depends on a wide variety of factors like the age of the furnace, the kind of damage that has occurred, and the importance of the repair. For example, the repair cost will go up if the furnace is old and replacement parts are hard to find. The cost is also likely to increase if there is significant damage and the furnace’s vital parts require replacement to make it work. Considering all these factors, the cost of emergency repair of a furnace is around $350 to $1000.

A homeowner’s insurance covers furnace repairs. However, there are a lot of terms and conditions that decide which type of damage gets covered under homeowners insurance. For instance, you will get reimbursement if your furnace gets damaged in a house fire. But it will not be covered by the insurance if it gets damaged due to improper usage. Also, damages caused by faulty installations or due to improper repairs will not be covered by these insurances.

The average repair and cleaning cost is somewhere around $300. There can be variations from this price point due to the kind of repair job that is required. If the task is complex or any costly parts require a replacement, the cost can increase. Regular maintenance and checkups by a technician are essential to ensure your furnace’s long life.

Many people think of carrying out repairs and checkups on their furnaces to cut costs and quicken the repairing process. While common tasks like cleaning and dusting can be done by anyone, a little complicated task like replacing a lamp or a valve is something that only an expert should do. Proper knowledge about how the internals of a furnace works and what to do when a particular problem occurs is essential if you are thinking of doing repairs on your own. The benefit of hiring a technician is that they will provide guaranteed results in the best possible way.

The furnace blower motor is an essential component of the furnace responsible for moving the hot air out into the ducts. Usually, the cost of a furnace motor is around $400, but the labor charges are the ones that can vary depending on a lot of factors. For example, the blower is hard to reach in some furnaces due to its position. The replacement charges in such cases can go as high up as $2000.

Annual furnace repair and maintenance cost mainly depends on the amount of maintenance work that has been done and the number of people involved in that task, apart from the complexity of the task. Sometimes carrying out regular maintenance without facing any problems is a good way of improving the performance of a furnace. The average cost per unit is around $400 to $1200. Oil furnace repairs are comparatively costlier than gas furnaces because they have more parts resulting in higher chances of faults.

A gas furnace usually runs for about 20 years on average. However, like all other things, this life span also depends on many factors like using conditions, regular maintenances, and timely repairs. If the owner takes proper care of the furnace, it can easily live for more than 20 years. Gas furnaces start giving out signals before it stops working in the form of faulty parts that are pivotal for the working of the furnace.

Furnace repair and maintenance is a systematic check of the entire heating system to ensure that it can run smoothly at optimal conditions without fail. A regular furnace repair includes:

  • Checking the vent and air intake systems
  • Checking the heat exchanger
  • Cleaning the blowers
  • Checking the current draw and electrical connections
  • Examining belts connected to the motor and fans

Special devices are used to measure the purity and oxygen level of the air delivered by the ducts. These are some of the best checks that are done regularly.


Furnace repairs, on average, take around 3 to 5 hours. If there are no specific problems with the functioning of the furnace, then the regular maintenance and cleaning procedure can be finished by a technician in 3.5 hours. However, if some significant problems require replacing some part, it will take more time depending on the part being replaced. Complex parts can even require more than one technician, significantly increasing the repairing cost.

A perfectly operating furnace results from intricate machine parts working in synchronization with each other. Any problem with the parts can negatively affect the performance of the furnace. Some reasons why a furnace stops working are loose circuit connection, damaged fuses, thermostat not turned on, blocked air filter, or cracked heat exchanger. More critical faults that can cause a furnace to stop working are a damaged blower motor, faulty thermostat, or collapsed duct system. All these problems can be avoided with regular maintenance by professionals.

Running a furnace with no heat is mainly due to clogged duct vents. This means that the hot air is getting produced by the furnace, but due to the trapped passage, the air cannot enter the room and is going out through the exhaust. This issue occurs commonly and, if not repaired, can lead to more significant problems in the form of damaged blower motors which can lead to fire and are very costly to repair. Clogged ducts can also lead to dust getting mixed with the air in a room, harming the occupants with respiratory problems.

First, check if the electrical connections are loose or not, be careful as the motors run on high AC voltage. Then check the ducts to see if there is a blockage due to a bird’s nest or other debris. If you find a blockage, then clear this with a broom. If the issue is something else, you will require a technician’s assistance. Call an expert for help and leave the furnace as it is.

A steady airflow and the furnace’s ability to maintain the temperature continuously is a signal that the furnace is working correctly. This is the way a layman user can understand if the device is working correctly or not. If you have any doubts about the performance, hire a professional who can carry out an in-depth search of the furnace to check if anything is wrong with it. The professionals will also check the air quality in the ducts to determine the performance of the furnace filters.

One of the most common furnace problems is related to a malfunctioning thermostat. The thermostat is usually out of battery without any prior signal, but you will be able to identify this if you hear the blower fan rotating continuously without any stops.
