Furnace Repair Service Commerce City

Is your furnace making strange noises in the middle of the night while temperatures drop below freezing outside? You're not alone. Over 30% of Commerce City homeowners will face an unexpected heating emergency this winter. Finding a reliable heating repair service can be the difference between a quick fix and days of discomfort for your family.

At Allen Service, with over 60 years of experience, we've been helping Commerce City families stay warm by fixing furnace problems big and small. Our local technicians know how Colorado's unique climate puts extra strain on heating systems, and we're ready to respond quickly when you need us most. From strange noises and cold spots to complete system failures, we fix it right the first time.

Signs You Need Furnace Repairs

Your furnace often sends warning signals before it fails completely. Recognizing these signs early can save you from uncomfortable cold nights and more expensive repairs later. Here are the key indicators that it's time to call for professional help:

  • Strange noises - Banging, whistling, grinding, or rattling sounds that weren't there before
  • Uneven heating - Cold spots throughout your home or rooms that never seem to get warm enough
  • Higher energy bills - Sudden increases in your utility costs without increased usage
  • Short cycling - Furnace turns on and off frequently without completing a full heating cycle
  • Pilot light problems - Yellow pilot light instead of blue (could indicate dangerous carbon monoxide)
  • Unusual odors - Smells like burning dust, plastic, or metallic scents when your furnace runs
  • Failure to start - System won't turn on or stays on but doesn't produce heat
  • Aging system issues - Furnaces over 15 years old experiencing any of these symptoms need immediate attention

Don't ignore these warning signs, especially during cold winter months when a minor issue today can become a comfort emergency tomorrow.

Common Furnace Problems

Understanding the most frequent furnace issues can help you identify problems early and know when to call for professional help. Commerce City homeowners often face similar general heating challenges, especially during our coldest months:

  • Dirty or clogged filters - The most common and easily fixed problem. Restricted airflow makes your furnace work harder, increases energy bills, and shortens system life.
  • Faulty ignition or pilot control - When your furnace doesn't light properly, it can't produce heat. This might be due to drafts, clogged components, or electronic ignition problems.
  • Thermostat malfunctions - Sometimes the issue isn't your furnace at all, but the device controlling it. Incorrect calibration or wiring problems can prevent proper heating.
  • Mechanical wear and tear - Belt and bearing issues cause unusual noises and reduced efficiency. These parts naturally wear out over time.
  • Lack of maintenance - Regular furnace tune-ups prevent many common problems. Dust buildup and loose connections often cause failures during the coldest weather.
  • Heat exchanger cracks - A serious safety issue that can release carbon monoxide into your home. Often happens in older units or poorly maintained systems.

Many of these problems start small but grow worse over time. Our technicians are trained to catch these issues early, saving you money and preventing mid-winter emergencies.
