Annual Furnace Tune-Ups & Maintenance Plans
The cheapest furnace repair is the one you never need. Tech On Call's annual fall tune-up catches cracked heat exchangers, weak ignitors, dirty burners, and gas leaks before they turn into mid-January no-heat calls or — worse — a carbon monoxide event. Most manufacturer warranties require documented annual service to stay valid, so the tune-up isn't just about reliability, it's about protecting the warranty on a $6,000+ system.
Every tune-up includes a full combustion analysis with a calibrated combustion analyzer, heat exchanger crack inspection, burner and flame sensor cleaning, gas pressure verification against manufacturer spec, CO testing at the supply registers, blower amp draw, and temperature rise measurement. We document everything in writing — you keep the record for the warranty and for resale.
Plan members get priority dispatch when you do call for repair, no after-hours overtime, and 15% off parts and labor. The plan typically pays for itself the first repair call. Pair with our same-day repair service for full coverage, and ask about adding AC maintenance for full HVAC coverage.

Why Maintenance Matters
What A Skipped Tune-Up Costs You
Diagnose · Repair · Restore
01
Cracked Heat Exchanger
The CO safety hazard. Annual inspection catches it before the CO detector does — or worse.
02
Dirty Burners & Flame Sensor
Causes incomplete combustion and short-cycling. 20-minute cleaning prevents it.
03
Voided Warranty
Most manufacturers require documented annual service to honor parts warranty. Skipping it is expensive.
04
Restricted Airflow
Dirty filter or blower wheel overheats the heat exchanger and shortens its life dramatically.
05
CO Leak Risk
We test CO at the supply registers — the only way to confirm combustion gases aren't entering living space.
06
Weak Ignitor / Sensor
Caught early, they're cheap. Caught when they fail in January, they're an emergency call.

Maintenance FAQ
Maintenance Questions
01
How often should I service my furnace?
Annually, in early fall before the first cold snap. Most manufacturer warranties require documented annual service to stay valid.
02
What does a furnace tune-up include?
Heat exchanger inspection, burner and flame sensor cleaning, gas pressure verification, combustion test, CO check at supply registers, blower amp draw, filter inspection, and thermostat calibration.
03
Do you offer maintenance plans?
Yes — from $19/mo for heating-only, $29/mo for full HVAC. Includes annual tune-up, priority dispatch, and 15% off parts and labor.
04
What's the difference between a tune-up and a maintenance plan?
A one-time tune-up runs $129. A plan adds priority dispatch, no after-hours overtime, and parts/labor discounts — the plan pays for itself the first repair.
05
Does maintenance keep my warranty valid?
Yes — most manufacturers require documented annual service to honor parts warranty. We keep the records on file.
06
Could my furnace be leaking carbon monoxide?
A cracked heat exchanger is the most common source of CO leaks from a furnace. Warning signs: soot around the burner area, a yellow (not blue) flame, headaches or dizziness when the furnace runs, and a CO detector alarm. If you suspect a leak, shut the furnace off at the breaker, open windows, and call us — we test combustion and inspect the heat exchanger as part of every diagnostic.
07
What cities do you serve for heating repair?
Every city in Riverside and San Bernardino County — Riverside, San Bernardino, Fontana, Rancho Cucamonga, Ontario, Corona, Moreno Valley, Temecula, Murrieta, Redlands, Hesperia, Victorville, and the Coachella Valley. Cold-snap nights in Hesperia, Victorville, and Yucaipa drive the most no-heat calls — we triage those first.
08
Do you offer financing on furnace replacement?
Yes — financing is available on qualifying furnace and heat pump installs. We'll walk through monthly payment options and California rebate eligibility (SoCalGas, SCE, federal IRA tax credits) before you commit.
