There is nothing worse than waking up on a frigid winter morning to a heater that is on the fritz, or worse, has completely died! You may be nervous about the potential cost of repairing a furnace. Here are a few factors that will affect the price of your furnace repair

What caused the issue?

Although most furnaces and forced air heating systems are reliable and perform for many years without major problems, system break downs can and do occur. Many problems that occur in furnaces and forced air heating systems result from cleaning and maintenance issues, while other causes of a malfunction involve problems with the mechanical or electrical components of the system.
If your furnace malfunction is caused by improper cleaning and maintenance, you may be able to fix the system by simply cleaning it out. If this is the case your repair will be relatively inexpensive.
If your problem is diagnosed as an electrical issue. The problem could be associated with something other than the furnace. Make sure to check all your circuits and breakers for an electrical malfunction elsewhere in the home. If this is the issue, you may also get through your repair inexpensive.
However, if the malfunctioning furnace is due to the breakdown of parts or components that need to be replaced the costs and labor may be a lot higher.

Cleaning Your System

Dirt is the biggest enemy of your furnace. It can waste fuel and drastically lower efficiency. In some cases, it can even cause the furnace to overheat. Dirt affects all the basic components of your furnace, so cleaning is the most important part of regular maintenance. The three parts of the furnace that should be cleaned are the filter system, the blower and the motor. If you have a furnace issue and have diagnosed that it is a cleaning problem, have your furnace professionally cleaned, and then schedule regular maintenance and cleaning. This is the best way to avoid a costly furnace repair in the future!

When to Repair or Replace

The average furnace lasts 10-15 years, so if your furnace is in that age range, it may be financially a better decision to consider furnace replacement than to get into a cycle of fixing regular problems as they arise with age.
Occasionally, the problem with your forced air heating system may be complex, such as a blown motor or a bent fan blade. In this case, a more involved repair is necessary. If your furnace or forced air heating system requires an extensive repair or if the repair approaches the cost of installing a new furnace, it may be in your best interest to go ahead and replace your forced air heating system.

Will a new system lower my bills?

Today's high-efficiency furnaces not only heat your home better, but they can save you on your energy bills. Many homeowners experience up to a 30% decrease in energy bills with a new efficient furnace or heating system. If you do end up having to pay for a new furnace it may be much more cost effective than your old furnace ever was.
