Services Offered by Furnace Repair Companies

Furnace repair companies offer various services to ensure your furnace works efficiently and effectively. We’ve outlined the most common ones below.

Repair and Maintenance

Timely professional repairs will restore your furnace's function, extend its life span, and optimize energy efficiency. Furnace repair experts are trained to handle broken blower motors, malfunctioning thermostats, clogged air filters, and more. Your technician can diagnose and repair problems like these to keep your furnace running efficiently. A qualified HVAC technician can also help with issues like damaged heat exchangers, possible gas leaks, faulty ignitions, or malfunctioning thermostats. Furnace repair technicians can also complete a routine HVAC system tune-up to avoid unnecessary breakdowns. This can involve inspecting and cleaning your furnace, lubricating moving parts, replacing air filters, and ensuring all components function properly.


HVAC providers can help mount a new furnace if yours is past repair. An expert can also help you upgrade 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 right furnace model for your budget and home requirements. Professional HVAC technicians are trained in industry standards and safety protocols for proper installation of a new furnace and connection. They can integrate a new system with your existing thermostat and air ducts. They'll complete a final inspection after installation to ensure your furnace runs optimally.


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

Emergency Services

Emergency furnace repair services will restore heat to your home if your furnace breaks down in the middle of winter. Many companies offer 24/7 services to help get your furnace up and running as soon as possible. These services help with unexpected breakdowns, malfunctions, and other safety concerns. Emergency services might be more expensive than a scheduled service, but it's worth it to protect your health. If your furnace fails during extreme weather conditions, and you're unable to open windows for fresh air, it can lead to discomfort and serious health risks from decreased indoor air quality.

Factors To Consider When Choosing a Local Castle Rock Furnace Repair Service

You should consider a number of factors when choosing a local Castle Rock furnace repair provider. We go over some important considerations below.

  • Cost: Compare pricing from several Castle Rock furnace repair companies. Look for transparent and competitive pricing, considering the scope of services offered. Beware of extremely low-cost options, which might compromise workmanship quality or involve subpar replacement parts.
  • Guarantees: Ask your furnace repair company about any guarantees or warranties it offers. Reputable service providers offer these guarantees to protect customers in case of any issues post-repair. Guarantees may cover both workmanship and replacement parts.
  • Licensing: Confirm that your furnace repair servicer holds all necessary licenses and certifications. This ensures that the technicians are qualified to handle furnace repairs safely and effectively. In Colorado, your HVAC contractor must obtain certification from your local city or municipal government.
  • Qualifications: Check a furnace repair company's qualifications and experience. Ideally, technicians should be well-trained and have expertise in various furnace makes and models. Ask about ongoing training programs to ensure a provider is up to date with the latest repair techniques.
  • Reputation and reviews: Online reviews and customer testimonials can give you an idea of a company's reputation and focus on customer satisfaction. Look for overall positive reviews and experiences, and pay attention to the way it addresses complaints and negative feedback.

How Much Does a Furnace Repair Cost?

The price of furnace repair varies depending on a number of factors, such as the HVAC unit type, the extent of the damage, and the price of replacement parts. Furnace repair costs an average of $461, but your total price depends on the situation. Below are some common furnace repairs and their average costs.

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