Services Offered by Furnace Repair Companies

Your local furnace repair provider offers a number of services to help your system work effectively. We’ve outlined the most common ones below.

Repair and Maintenance

A timely repair restores the furnace's function, extends its life span, and optimizes energy efficiency. Furnace repair companies can diagnose and repair any issues with your furnace, including a malfunctioning thermostat, clogged air filter, or broken blower motor. Qualified HVAC technicians examine and fix individual problems such as malfunctioning thermostats, damaged heat exchangers, faulty ignitions, or possible gas leaks. Furnace repair professionals can also provide routine HVAC maintenance to avoid unnecessary breakdowns. This can include jobs such as inspecting and cleaning your furnace, lubricating moving parts, replacing air filters, and ensuring that all components work correctly.


HVAC companies can help install a new furnace if yours is past repair. An expert can also help with upgrading to a more energy-efficient model, like 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 you based on your budget and home requirements. HVAC technicians follow industry standards and safety protocols to ensure safe furnace replacement and connection. They also integrate the new system with existing thermostats and air ducts. After installation, the company performs a final inspection to ensure the 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 causes. Inspections typically include testing the thermostat's accuracy, inspecting the burner and ignition system, checking for any gas or fuel leaks, cleaning and replacing air filters, and examining the heat exchanger for cracks or damage. Your technician will look at the heating system's efficiency and safety and make any necessary adjustments or repairs. Annual furnace tune-ups encourage optimal performance and help prevent potential breakdowns, promoting a safe living environment during chilly winters.

Emergency Services

If your furnace breaks down on a cold winter night, some furnace repair companies offer emergency repair services to get your system up and running as quickly as possible. These services are available 24/7 for unexpected breakdowns, malfunctions, and other safety concerns. When a furnace fails in extreme weather conditions, and it's not possible to open windows for fresh air, it can lead to serious discomfort and health risks due to decreased indoor air quality. Emergency services cost more than scheduled services, but protecting your health is worth it.

Factors To Consider When Choosing a Local Leesburg Furnace Repair Service

There are multiple factors to consider when hiring a local Leesburg furnace repair provider. We go over some important considerations below.

  • Cost: Compare multiple Leesburg furnace repair companies to find the best service offerings and prices. Look for transparent and competitive pricing, but be wary of companies that quote extremely low rates. These providers may make up the difference with low-quality workmanship or subpar replacement parts.
  • Guarantees: Look into the guarantees or warranties offered by your furnace repair service. A reliable company should back its work with guarantees on parts and repair work. This gives you peace of mind knowing you can depend on the service provider if any issues arise after repairs.
  • Licensing: Confirm that your furnace repair servicer holds all required licenses and certifications. This ensures that the technicians are qualified and trained to safely handle furnace repairs. HVAC contractors in Virginia may have either a journeyman or full contractor's license from the Virginia Board for Contractors.
  • Qualifications: You can inquire about a company's training policies as well as the experience of its technicians. Companies that provide ongoing training are more likely to have technicians that are up to date on the latest repair techniques. You want a company that employs well-trained technicians who are experienced in working with various furnace makes and models.
  • Reputation and reviews: Check online testimonials and reviews from previous customers 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 reviews and complaints. This can reveal a great deal about a company's commitment to customer service.

How Much Does a Furnace Repair Cost?

Several factors affect the cost of furnace repair. These include the type of HVAC unit, extent of the damage, and price of replacement parts. On average, furnace repair costs $468, although the prices can vary depending on the details. Below are some common furnace repairs and their average costs.

  • Broken thermostat: $84–$421
  • Cleaning: $51–$67
