Furnace Maintenance & Seasonal Tune-Ups in Gering, NE

We start by asking about your furnace’s performance over the past year. Did it run smoothly all winter or did you notice problems? Have you changed the filter regularly? Is the thermostat accurate? Have you noticed any sounds or smells? This conversation guides our inspection toward systems that are showing early wear while confirming that trouble-free systems are truly healthy.

• Interview about heating performance, comfort complaints, and any unusual sounds or smells
• Review maintenance history and prior service records
• Assess filter replacement frequency and schedule recommendations
• Discuss thermostat accuracy and programming optimization opportunities
• Document baseline system condition

Before running diagnostics, we visually inspect the furnace, ductwork, venting, and gas connections. We look for: corroded piping, loose connections, damaged insulation on ductwork, visible cracks in the heat exchanger (using a flashlight), debris or corrosion around the burners, and proper clearance around the furnace.

• Inspect furnace exterior for corrosion, cracks, or damage
• Check gas piping for leaks, corrosion, or loose connections
• Verify venting is clear and properly sealed
• Inspect ductwork for leaks, gaps, and proper insulation
• Confirm combustion air intake is unobstructed
• Look for signs of moisture, debris, or pests inside furnace cabinet

We measure gas pressure at the furnace inlet using a manometer and compare it against the nameplate specifications. If pressure has drifted from the last inspection, we adjust the furnace’s regulator to restore proper operation. Incorrect pressure affects flame size, burner performance, and heating output.

• Measure inlet gas pressure with precision manometer
• Compare against furnace nameplate specifications
• Adjust pressure regulator if needed
• Check all connections for leaks using detection equipment and soap solution
• Verify manual shutoff valve operates smoothly

We test the ignition system (electronic igniter or standing pilot), verify control board function, measure voltage at key circuits, and inspect for corroded or loose electrical connections. For electronic ignition furnaces, we test igniter continuity and confirm it’s producing spark. For pilot-lit systems, we verify the pilot lights reliably and the thermocouple generates proper voltage.

• Test electronic igniter continuity and voltage
• Inspect igniter for damage or carbon buildup
• Test flame sensor operation and cleanliness
• Verify control board is sending proper signals
• Measure voltage at all critical circuits
• Check all electrical connections for corrosion or looseness

Using a video scope, we inspect the heat exchanger for corrosion, rust, cracks, or internal damage. The heat exchanger is the most critical component — damage here creates carbon monoxide hazards and loss of efficiency. Video inspection lets us document any developing issues while they’re still minor.

• Use video scope to inspect heat exchanger thoroughly
• Document any corrosion, rust, or developing cracks
• Measure heat exchanger temperature rise
• Inspect burner assemblies for debris and corrosion
• Clean burner orifices and ensure proper alignment
• Photograph findings for your records

We test every safety control: the high-temperature limit switch (prevents overheating), the pressure switch (confirms airflow before ignition), the rollout switch (prevents external heat damage), and sequence controls. We verify each responds properly to system conditions and won’t cause nuisance shutoffs.

• Test limit switch response to high temperature
• Verify pressure switch detects airflow correctly
• Check rollout switch operation
• Measure thermostat accuracy and response time
• Confirm blower motor speed and noise levels
• Test temperature rise to verify efficient heat transfer
• Run system through multiple heating cycles to confirm reliability

You’ll leave with a detailed inspection report showing what we found, what we cleaned or adjusted, what safety tests passed, and baseline readings for next year’s comparison. We’ll discuss any developing issues and recommend specific maintenance or repairs.

• Provide written inspection report with findings and photos
• Discuss any developing issues and recommend solutions
• Show before-and-after measurements documenting adjustments
• Explain what we found and why each component matters
• Answer questions about heating efficiency and thermostat programming
• Discuss Superhero Club membership benefits and schedule next year’s appointment
• Provide our direct contact information and seasonal heating tips
