What Is Included in a Furnace Repair?

Furnace repair includes a wide range of services, from diagnosing the problem to replacing parts and performing routine maintenance. Our expert heating repair technicians will inspect your furnace to determine the best course of action and make any necessary repairs or adjustments. This could include cleaning the system, checking for proper airflow, replacing old or broken parts, and more depending on your furnace's specific problem. We also provide furnace tune-up services that can help ensure your furnace is running as efficiently as possible.

Signs You Need Furnace Repairs

If your furnace is not working efficiently or consistently, it may be time for a repair. Watch out for these common warning signs:

  • Loud noises – banging, rattling, or screeching can indicate mechanical issues.
  • Strange odors – musty or burning smells may point to dirty components or electrical problems.
  • Frequent cycling on and off – often a sign of a malfunctioning thermostat or airflow problem.
  • Uneven heating – some rooms warmer than others can mean blocked vents or failing parts.
  • Increased energy bills – a sudden spike in costs can indicate your furnace is working harder than it should.

If you're experiencing any of these signs, contact our team of experts at Allen Service to inspect and repair your furnace promptly. Acting early can prevent more costly breakdowns later.

Common Furnace Problems

Several issues can affect furnace performance. Some of the most common include:

  • Dirty or clogged filters – reducing airflow and efficiency.
  • Pilot light or ignition control issues – preventing the furnace from starting properly.
  • Clogged burners – lowering heat output and increasing strain on the system.
  • Thermostat malfunctions – causing inaccurate temperature readings or irregular cycling.
  • Blower or motor wear – reducing airflow and leading to uneven heating.

Our expert technicians at Allen Service are equipped to handle any furnace repair job, from small fixes to major repairs.

Frequently Asked Questions

Have questions? We are here to help. Still have questions or can't find the answer you need? Give us a call at 970-431-6574 today!

  • The most common furnace problem is a dirty or clogged air filter, which restricts airflow and forces your system to work harder. This leads to inefficient operation, higher energy bills, and potential overheating. Other frequent issues include faulty ignition systems, malfunctioning thermostats, and worn-out blower motors. Regular maintenance can prevent most of these problems and extend your furnace's lifespan.
  • The average cost of furnace repair in Fort Collins ranges from $150 to $450, depending on the specific issue and parts required. Simple fixes like replacing ignitors or flame sensors tend to be on the lower end, while more complex electrical or mechanical repairs cost more. At Allen Service, we provide upfront, transparent pricing before any work begins, and we offer financing options for larger repairs to make unexpected heating expenses more manageable.
  • The most expensive furnace repair is typically replacing the heat exchanger, which can cost between $1,500 and $3,500 depending on your furnace model. Heat exchanger cracks often indicate a furnace nearing the end of its useful life. Other costly repairs include replacing the blower motor assembly ($800-$1,500) or control board ($500-$1,100). When facing expensive repairs on older units, our technicians will honestly advise whether repair or furnace installation offers better long-term value.
  • A furnace can stop working due to several issues, including electrical problems (tripped circuit breakers, blown fuses), thermostat malfunctions, ignition or pilot light failures, broken blower motors, or safety switch activations. Gas furnaces may stop due to gas supply interruptions or valve issues. Preventative maintenance can identify potential problems before they cause complete system failure. If your furnace stops working, our Allen Service technicians are available for prompt diagnosis and repair to restore your home's comfort quickly.
