Services Offered by Furnace Repair Companies

Local furnace repair providers offer a number of services to ensure your furnace runs efficiently. We outline some common offerings below.

Repair and Maintenance

Timely repairs help extend your furnace's life span and optimize its energy efficiency, on top of restoring function. Furnace repair professionals are trained to deal with broken blower motors, malfunctioning thermostats, clogged air filters, and more. Your technician can help diagnose and repair these and other issues to keep your furnace running efficiently. A qualified HVAC technician can also handle issues like faulty ignitions, possible gas leaks, malfunctioning thermostats, or damaged heat exchangers. Furnace repair professionals can also handle routine HVAC maintenance to avoid unnecessary breakdowns. This can include jobs such as inspecting and cleaning your furnace, replacing air filters, lubricating moving parts, and generally making sure all components work correctly.


HVAC providers can help install a new furnace if yours is past repair. An expert can also help you upgrade to a more energy-efficient model, such as a heat pump. First, a skilled technician will assess your heating needs and home’s layout. Then, the tech will recommend the best furnace model for your budget and home requirements. Professional HVAC technicians are trained in industry standards and safety protocols for proper furnace replacement and connection. They can integrate your new system with your existing air ducts and thermostats. Your provider will complete a final inspection after installation to ensure your furnace runs optimally.


If your furnace isn’t turning on, you want to schedule a thorough inspection with a furnace repair provider. A technician will examine each component of your furnace to identify potential issues. Inspections usually include checking for any gas or fuel leaks, examining the heat exchanger for cracks or damage, testing the thermostat's accuracy, inspecting the burner and ignition system, and cleaning and replacing air filters. Yearly inspections of this type facilitate optimal heating system performance, help avoid possible breakdowns, and promote safe living during cold winters. Your technician will verify your system's safety and efficiency and make any needed repairs.

Emergency Services

If your furnace breaks down on a cold winter night, some furnace repair companies have emergency repair services to get your system up and running promptly. These services are available 24/7 for unexpected malfunctions, breakdowns, and other safety concerns. When a furnace fails in extreme weather conditions, and you're unable to open windows for fresh air, it can lead to serious discomfort and health risks from decreased indoor air quality. Though emergency services will cost more than scheduled services, it’s worth it to protect your health.

Factors To Consider When Choosing a Local Ashburn Furnace Repair Service

There are a number of important considerations for selecting a local Ashburn furnace repair provider. We go over some important factors below.

  • Cost: We recommend comparing multiple Ashburn furnace repair companies to look for the best service offerings and prices. Look for transparent and competitive pricing, but avoid companies with extremely low rates. These providers often make up the difference with low-quality workmanship or subpar replacement parts.
  • Guarantees: Reliable furnace repair companies should provide warranties or guarantees on their parts and workmanship. Companies that stand behind their work offer you peace of mind should something go wrong post-repair.
  • Licensing: Verify that your furnace repair provider holds the licenses and certifications required by local and state authorities. Proper licensing ensures technicians are qualified and trained to handle furnace repairs safely and effectively. HVAC contractors in Virginia may have either a journeyman or full contractor's license from the Virginia Board for Contractors.
  • Qualifications: Ask about the experience and qualifications of a furnace repair company. You want technicians that are well-trained and experienced at working with various furnace makes and models. Inquire about a company's training programs to confirm that technicians are educated on the latest industry standards.
  • Reputation and reviews: You can read online reviews and testimonials to get a sense of a company's reputation. Look for a provider with overall positive reviews, but also be mindful of how it addresses negative feedback. This can tell you a great deal about a company's commitment to customer service.

How Much Does a Furnace Repair Cost?

The cost of furnace repair depends on multiple factors, such as the HVAC unit type, the extent of the damage, and the price of replacement parts. Furnace repair costs an average of $468, but the final price depends on the details. The following are some common furnace repairs, as well as their average costs.

  • Broken thermostat: $84–$421
  • Cleaning: $51–$67
  • Cracked heat exchanger: $1,684–$2,947
  • Damaged blower bearings: $25–$126
  • Damaged blower belt: $25–$93
