Services Offered by Furnace Repair Companies

Your local furnace repair provider will offer various services to keep your furnace running efficiently. We outline some common offerings below.

Repair and Maintenance

Timely repairs restore furnace function, extend its life span, and optimize energy efficiency. Furnace repair experts can diagnose and fix a number of common furnace issues. These include malfunctioning thermostats, clogged air filters, or broken blower motors. Qualified HVAC technicians can also handle problems such as malfunctioning thermostats, damaged heat exchangers, faulty ignitions, and possible gas leaks. Furnace repair experts can also complete routine HVAC system servicing to avoid unnecessary breakdowns. This can include jobs such as inspecting and cleaning your furnace, lubricating moving parts, replacing air filters, and generally making sure all components work correctly.


HVAC providers can help mount a new furnace if yours is beyond repair. An expert can also help with upgrading 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 you based on your budget and home requirements. Your HVAC technician can integrate a new system with existing thermostats and air ducts. They're trained to follow industry safety protocols and standards to ensure proper furnace replacement and connection. To be sure everything is running optimally, your technician will perform a final inspection after installation.


You should schedule an inspection through a furnace repair company if you notice your furnace failing to turn on. During the inspection, a technician will look at every component of your furnace to identify potential issues. Inspections usually include checking for any gas or fuel leaks, testing the thermostat's accuracy, examining the heat exchanger for cracks or damage, cleaning and replacing air filters, and inspecting the burner and ignition system. Yearly inspections of this type encourage optimal heating system performance, help prevent potential breakdowns, and promote safe living during cold winters. A technician will verify your system's safety and efficiency and make the necessary repairs.

Emergency Services

If your furnace breaks down on a cold winter night, some furnace repair companies provide emergency repair services to get your system up and running quickly. These services are available around the clock for unexpected malfunctions, breakdowns, and other safety concerns. Emergency services might be more expensive than scheduled services, but protecting your health is worth it. If your furnace fails during extreme weather, and it's not possible to open windows for fresh air, it can cause discomfort and serious health risks due to the decreased indoor air quality.

Factors To Consider When Choosing a Local Littleton Furnace Repair Service

You should consider a number of factors when hiring a local Littleton furnace repair service. We go over some of the most important below.

  • Cost: Compare pricing and services offered by several Littleton furnace repair providers. Look for competitive and transparent pricing, but avoid extremely low-cost options. Abnormally low prices may indicate that a company is making up the difference by compromising the quality of work or materials.
  • Guarantees: Look into the guarantees or warranties provided by the furnace repair provider. A reliable company should back its work with guarantees on repairs and replacement parts. This assurance provides peace of mind knowing you can rely on your service provider if any issues arise after repairs.
  • Licensing: Verify that the furnace repair company holds the licenses and certifications required by local and state authorities. Proper licensing ensures technicians are qualified to handle furnace repairs safely. In Colorado, your HVAC contractor must obtain certification from your local city or municipal government.
  • Qualifications: Learn about the qualifications and experience 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 up to date on current industry standards for repairs.
  • Reputation and reviews: Read online reviews and customer testimonials to get a feel for a company's reputation. Mostly positive reviews are indicative of quality services. You can also verify a company's commitment to customer satisfaction by seeing how it addresses complaints and other negative feedback.

How Much Does a Furnace Repair Cost?

Certain factors affect the price of repairing your furnace. These include the type of HVAC unit, extent of the damage, and cost of replacement parts. On average, furnace repair costs $461, though this varies depending on the details. The following are some common furnace repairs, as well as their average costs.

  • Broken thermostat: $83–$417
  • Cleaning: $50–$67
  • Cracked heat exchanger: $1,667–$2,918
  • Damaged blower bearings: $25–$125
