Understanding Furnace Repair Needs in Windsor, CO
When your furnace stops working during a Colorado winter, you need reliable heating repair services immediately. At Northern Air, we understand the urgency of restoring warmth to your home. Since our founding in 1992, we’ve responded to thousands of furnace repair calls throughout Windsor and the entire Front Range. Our family-operated approach means we treat every home as if it were our own, ensuring your heating system receives the meticulous attention it deserves.
Winter temperatures in Windsor regularly drop below freezing, with January averages hovering around 15°F at night. These harsh conditions put tremendous strain on residential heating systems, particularly aging furnaces that haven’t received regular maintenance. Our more than 40 years of experience in heating and air conditioning repair has taught us that most furnace failures occur during the first major cold snap of the season, when systems suddenly shift from moderate to heavy use. We’re available 24/7 because we know heating emergencies don’t follow business hours.
Common Furnace Problems We Diagnose and Repair
The majority of furnace repair calls we receive in Windsor involve predictable mechanical and electrical issues. Ignition system failures account for approximately 35% of winter service calls, often caused by dirty flame sensors or faulty ignitor components. These critical parts ensure your furnace lights properly and maintains consistent combustion. When flame sensors accumulate carbon deposits, they can’t accurately detect the presence of flames, causing the system to shut down as a safety precaution.
Blower motor problems represent another significant category of repairs we handle. The blower motor circulates heated air throughout your home’s ductwork, and when bearings wear out or capacitors fail, you’ll notice reduced airflow or complete system failure. Heat exchanger cracks, while less common, pose serious safety risks including carbon monoxide leaks. Our technicians use specialized equipment to inspect heat exchangers thoroughly, as visual detection alone often misses hairline cracks that develop from years of thermal expansion and contraction.
How Northern Air Approaches Furnace Repair
When you call Northern Air for furnace repair, our systematic approach ensures accurate diagnosis and lasting solutions. We begin with a complete system evaluation, checking electrical connections, measuring gas pressure, testing safety controls, and analyzing combustion efficiency. This thorough inspection often reveals underlying issues that might not be immediately apparent but could cause future breakdowns if left unaddressed.
Our diagnostic process includes:
- Thermostat calibration testing: ensuring accurate temperature readings and proper communication with the furnace
- Air filter inspection: checking for restrictions that reduce efficiency and strain components
- Ductwork evaluation: identifying leaks or blockages affecting heat distribution
- Safety control verification: testing limit switches and rollout sensors that prevent dangerous operating conditions
- Combustion analysis: measuring carbon monoxide levels and adjusting gas pressure for optimal efficiency
