Professional Furnace Maintenance & Inspections

Routine furnace maintenance and inspections are the key to efficiency, safety, and system longevity. During a professional tune-up, our technicians carefully inspect, clean, and adjust your furnace to prevent breakdowns, lower energy bills, and keep your system running at peak performance.

Beware of “low-cost furnace check-ups.” Many advertised specials only provide a quick glance at your system. That is not a real tune-up or inspection.

Our maintenance services are comprehensive — checking safety controls, airflow, burners, electrical components, and more. This attention to detail protects your home and ensures your furnace operates at maximum efficiency.

Furnace Repair, Maintenance & Inspection FAQs

How often should I schedule a furnace tune-up or inspection?

We recommend a professional furnace tune-up and inspection once a year — ideally before the heating season begins. Annual service ensures your system runs safely, efficiently, and helps prevent costly breakdowns when you need heat most.

At Fort Collins Heating & Air Conditioning, our Heating Season Ultimate Tune-Up is a comprehensive inspection and service, not just a quick check-up. During your appointment, our technician will:

  • Replace or clean the air filter

  • Test overall system operation

  • Check the thermostat for accuracy and fault codes

  • Clean the furnace cabinet inside and out

  • Clean burners and the pilot assembly

  • Inspect heat exchangers for safety

  • Inspect the blower wheel and motor for cleanliness

  • Record amp draw on blower and draft motors

  • Inspect and tighten electrical connections

  • Inspect all safety controls

  • Test for proper drafting of the vent and inspect vent condition

  • Test for gas leaks

  • Perform carbon monoxide sampling in both the airstream and exhaust flue, recording all readings

  • Record entering and leaving air temperatures

  • Check gas manifold pressure

  • Run defrost cycle and test auxiliary heat (for heat pumps)

  • Inspect and clean the condensate drain

  • Inspect the water heater for proper draft, leaks, and age

This detailed process ensures your furnace is tuned for maximum efficiency, safety, and reliability.

No — a low-cost furnace check-up is usually just a quick visual inspection. It won’t include a full cleaning, safety testing, or performance measurements.

A true tune-up, like our Ultimate Heating Season Tune-Up, involves a complete inspection, adjustments, and safety testing to protect your home and maximize your furnace’s lifespan.
