When winter rolls down the Front Range, a dependable, efficient furnace means cozy nights—not cold-weather stress. Endurance HVAC provides preventive furnace maintenance that keeps heat steady, bills predictable, and safety non-negotiable. We’re a family-owned crew that treats customers like neighbors, combining local care with certified know-how so your system gets exactly what it needs—no upsells, no shortcuts. Thinking about a seasonal furnace tune-up before the freeze? Here’s what we do, why it matters, and how to book in minutes with a company you can trust.
Book a furnace inspection you can trust
A comprehensive furnace inspection isn’t a pitch—it’s clarity. Our certified HVAC technicians document your system’s condition, verify safe operation, and record performance benchmarks you can keep. We follow manufacturer guidance and Colorado best practices for annual furnace inspection and home furnace inspection, so you know where you stand before the first hard freeze. If your home runs on gas, we also offer a focused gas furnace inspection that reviews combustion quality, venting, and gas train integrity. Bottom line: straight answers, honest diagnostics, and peace of mind for your family. If the report shows your system is near end of life, consider furnace installation for a smooth, hassle-free upgrade.
What our furnace safety inspection includes
Our furnace safety inspection is built on transparency and E-E-A-T. We examine the heat exchanger for cracks or corrosion; verify combustion air and burner condition; measure gas pressure and check for leaks; test ignition systems and all safety controls; confirm electrical connections and control boards; evaluate filter condition, static pressure, and airflow at return and supply; verify thermostat calibration and proper cycling; and visually assess ductwork and cabinet seals. Every step aligns with manufacturer-recommended maintenance, and every finding is documented so you can decide with confidence—no pressure.
Carbon monoxide & venting checks
Safety starts with clean combustion and correct venting. Our carbon monoxide check includes a carbon monoxide test and full combustion analysis to assess CO levels, oxygen/CO₂ balance, and stack temperature under real operating conditions. We pair it with a flue and vent inspection to confirm proper draft, ensuring exhaust gases leave the home reliably—even in windy or low-pressure weather. It’s combustion safety you can count on, because your family deserves certainty, not guesses.
Full-service furnace tune-up: what’s included
Schedule a furnace tune-up and we move beyond inspection to optimize performance. Expect a seasonal tune-up that targets small inefficiencies before they become big energy costs. We perform deep internal cleaning to remove soot and debris that restrict airflow, apply targeted lubrication to cut friction and noise, and calibrate ignition, flame sensor, and blower so starts are crisp and cycles smooth. Burners are realigned for even flame patterns; temperature rise and draft are checked against nameplate specs; filters are replaced as applicable, and airflow imbalances are flagged with plain-English recommendations. Result: steadier heat, fewer mid-season surprises, and longer life from the parts you rely on most. If we uncover an issue that needs prompt attention, schedule furnace repair for fast, precise fixes.
Benefits: efficiency, safety, and lower energy costs
Routine service is the simplest way to improve furnace efficiency while protecting your home. A tuned furnace burns cleaner, moves air more freely, and reduces strain on motors and heat exchangers—helping extend furnace lifespan and lowering the risk of emergency breakdowns on the coldest nights. You’ll feel more even room-to-room temperatures, hear quieter operation, and often see utility bills drop as energy efficiency improves. Equally important, our safety checks guard against carbon monoxide exposure and venting issues most homeowners can’t spot on their own.
Pricing & straightforward scheduling
We keep it simple with flat-rate furnace maintenance and upfront pricing, so you know the cost before we arrive. Booking takes moments with easy online scheduling for furnace service, followed by clear confirmations and reminders. Want the best value? Our tiered maintenance plans—Silver, Gold, and Platinum—bundle seasonal inspections, filter changes, combustion analysis, and thorough cleanings into one predictable plan. Plans help you skip peak-season rushes and keep warranty-friendly service on schedule year-round.

Frequently Asked Questions
How often should I get a furnace inspection?
Most homes benefit from annual service, ideally before the first deep cold. The recommended frequency for furnace maintenance is once per year because components like flame sensors, burners, and filters degrade with use and dust buildup. The best time of year for a furnace tune-up is late summer through early fall, giving you scheduling flexibility and time to handle minor fixes before demand spikes. Homes with pets, allergy concerns, or high-efficiency equipment may benefit from a mid-season filter check to keep the maintenance schedule on track.
What’s the difference between an inspection and a tune-up?
Think of an inspection as a status report and a tune-up as performance optimization. In the inspection vs tune-up: what’s included conversation, the inspection verifies safety controls, code compliance, and overall health—documenting findings so you can plan ahead. The tune-up adds cleaning & calibration, including precise adjustments to ignition, flame sensing, and blower operation, plus performance testing to confirm proper temperature rise and draft. Both strengthen safety checks, but the tune-up typically boosts efficiency and quiets operation by addressing buildup and alignment issues an inspection alone won’t fix.
