How Much Does It Cost To Repair A Furnace?

As a homeowner, I understand how important it is to keep your furnace in good working order. Not only is a malfunctioning furnace uncomfortable, but it can also be dangerous. However, when your furnace does break down, the cost of repair can be a major concern.

In this article, We will discuss the factors that affect furnace repair cost, the average cost of furnace repair, common furnace problems, and their costs, DIY vs professional furnace repair – which is more cost-effective, tips for reducing furnace repair costs, choosing the right furnace repair service, furnace repair cost vs replacement cost – which is the better option, and furnace maintenance tips to avoid costly repairs.

The Average Cost of Furnace Repair

The average cost of furnace repair is approximately $300 to $500. However, more extensive repairs can cost much more. For example, replacing a blower motor can cost anywhere from $400 to $1,500, while replacing a heat exchanger can cost anywhere from $1,500 to $4,000.

Factors that Affect Furnace Repair Cost

The cost of furnace repair can vary depending on several factors. One of the most significant factors is the type of repair needed. For example, a simple repair like replacing a thermostat or a filter will cost less than a major repair like replacing a blower motor or a heat exchanger. The age of the furnace can also affect the cost of repair. Older furnaces that require more extensive repairs may be more expensive to fix. The location of the furnace can also affect the cost of repair. If the furnace is in a hard-to-reach location or requires special equipment to access, the cost of repair may be higher.

Another factor that can affect the cost of furnace repair is the time of year. During the busy season, which is typically the winter months, furnace repair companies may charge more for their services due to increased demand. Finally, the cost of labor can also affect the cost of furnace repair. Some companies charge more for labor than others, so it’s important to get quotes from several different companies before making a decision.

Common Furnace Repair Problems and Their Costs

There are several common furnace problems that homeowners may experience. One of the most common problems is a malfunctioning thermostat. The cost of repairing a thermostat can vary depending on the type of thermostat and the extent of the repair needed. On average, repairing a thermostat can cost between $100 and $300.

Another common problem is a dirty or clogged filter. The cost of replacing a filter can vary depending on the type of filter needed. On average, replacing a filter can cost between $20 and $50. Other common problems include a malfunctioning blower motor, a faulty ignition system, and a damaged heat exchanger. The cost of repairing these problems can vary widely depending on the extent of the repair needed.

Tips for Reducing Furnace Repair Costs

While furnace repairs may be unavoidable, there are several tips homeowners can follow to reduce the cost of repairs. One of the most important tips is to schedule regular maintenance for your furnace. Regular maintenance can help identify potential problems early on, which can prevent more extensive and expensive repairs down the line.

Another tip is to replace your furnace filter regularly. A dirty or clogged filter can cause your furnace to work harder, which can lead to more frequent breakdowns and repairs. Additionally, homeowners can save money on repairs by choosing a reputable furnace repair service and getting multiple quotes before making a decision.

Choosing the Right Furnace Repair Service

Choosing the right furnace service can make all the difference when it comes to the cost and quality of repairs. When choosing a furnace repair service, it’s important to look for a company with experience and a good reputation. Additionally, homeowners should look for a company that offers warranties and guarantees on their work.

Another important consideration is the cost of repairs. While cost should not be the only consideration, it’s important to get multiple quotes from different companies before making a decision. Finally, homeowners should look for a company that offers emergency repair services, as furnace breakdowns can happen at any time.

Furnace Repair Cost vs Replacement Cost

When faced with a major repair, homeowners may wonder if it’s more cost-effective to service or replace their furnace. While repairs may be cheaper in the short term, they may not be the best long-term solution. Older furnaces may require more frequent repairs, which can add up over time. Additionally, older furnaces may be less energy-efficient, which can result in higher utility bills.

Replacing an old furnace with a new, energy-efficient model can save homeowners money on utility bills and reduce the need for frequent repairs. While the upfront cost of a new furnace may be higher than the cost of repairs, it can be a worthwhile investment in the long run.

Furnace Maintenance Tips to Avoid Costly Repairs

Regular furnace maintenance is the key to avoiding costly repairs. Homeowners can perform some maintenance tasks themselves, such as replacing the furnace filter and cleaning the furnace blower. However, it’s also important to schedule regular maintenance with a professional furnace repair service.

During a maintenance appointment, a professional technician will inspect and clean the furnace, identify potential problems, and make any necessary repairs. Regular maintenance can help extend the life of your furnace and prevent costly breakdowns and repairs.


Understanding the cost is an important part of being a homeowner. By knowing the factors that affect repair costs, common furnace problems and their costs, and the benefits of professional repair services, homeowners can make informed decisions about furnace repair and maintenance. Additionally, by following tips for reducing furnace repair costs and choosing the right furnace repair service, homeowners can save money on repairs and keep their furnaces running smoothly for years to come.
