Most furnace failures happen on the coldest night of the year. An annual tune-up catches worn parts, dirty burners, and safety issues before they leave you without heat.
Furnace Tune-Up Report
System Health: Ready for Winter
All checks passed
One tune-up can prevent the most common winter breakdowns.
Your furnace works hardest on the coldest days. Without maintenance, that's when it fails.
Every tune-up follows a comprehensive checklist. Nothing gets skipped.
Inspected for cracks and corrosion. A compromised heat exchanger is the leading cause of carbon monoxide leaks in homes.
Cleaned and flame pattern checked. Dirty or misaligned burners waste gas and can produce dangerous combustion byproducts.
Tested and cleaned. A dirty flame sensor is the number one cause of "furnace won't stay lit" calls every winter.
Checked for blockages, proper draft, and tight connections. Venting issues put combustion gases back into your living space.
Measured with a manometer at the manifold. Incorrect gas pressure reduces efficiency and shortens heat exchanger life.
Amp draw tested and bearings inspected. A failing blower motor overheats the system and triggers limit switch shutdowns.
Checked for accuracy. A thermostat off by even 2 degrees causes unnecessary cycling and wasted energy all season.
Inspected and replaced if needed. A clogged filter restricts airflow, overheats the furnace, and drives up your gas bill.
Fall is the ideal time for furnace maintenance. Book before the first cold snap and avoid the holiday rush.
Before heating season begins. This is when most manufacturers recommend service. Catch issues while it's still warm enough to schedule comfortably.
If you notice any of these, don't wait for fall. Schedule a tune-up now to prevent a mid-winter failure.
"Had our furnace tuned up in October. The tech found a cracked flame sensor that would have left us without heat by December. Replaced it on the spot. Thorough and honest service."
"Six years of annual tune-ups with Next Phase. Our Lennox furnace runs perfectly every winter. Gas bills have stayed flat even as rates went up. Maintenance pays for itself."
"The technician checked the heat exchanger, cleaned the burners, tested the gas pressure, and showed me everything he found. First company that actually walked me through the inspection."
"Our furnace is 18 years old and still going strong. Annual maintenance is the only reason. Next Phase has been servicing it for the last four years. Highly recommend their tune-up service."
"Scheduled a fall tune-up after moving into our new home. They found the previous owner hadn't changed the filter in over a year. Everything cleaned, adjusted, and running perfectly now."

Once a year, ideally in early fall before you need heat. Annual service keeps the system efficient, catches worn parts early, and satisfies manufacturer warranty requirements. If your furnace is over 15 years old, a twice-yearly check is worth considering.
In most cases, yes. Carrier, Trane, Lennox, Goodman, and Rheem all require proof of annual professional maintenance to honor warranty claims. If a heat exchanger fails and you have no service records, the claim will likely be denied.
We inspect the heat exchanger, clean the burner assembly, test the ignitor and flame sensor, check flue draft and venting, measure gas pressure, test the blower motor, verify thermostat calibration, and replace or inspect the air filter. The full visit takes about 60–90 minutes.
Yes. Most furnace problems — cracked heat exchangers, dirty flame sensors, gas pressure drift — produce no obvious symptoms until the system fails completely. A tune-up catches these issues while they're still minor and inexpensive to fix.
With annual professional maintenance, 20–25 years is typical. Without it, most furnaces start having major issues between 10–15 years. Regular service is the single biggest factor in how long your furnace lasts.
Book your annual furnace tune-up. We'll inspect every component, catch anything that's wearing, and make sure your system is safe and ready for winter.
