No surprise costs. We give you a free estimate before we start and build service plans around your comfort goals and your budget.
Warranties You Can Count On
All work comes backed by secure warranties, and flexible financing options are available if you need them.
Costless Comfort Protection Plans
Our Costless Comfort Protection Plans give you a straightforward way to stay ahead of maintenance without having to remember to call every season. Each plan includes two professional tune-ups per year, one before the cooling season and one before the heating season, plus filter replacement. You also get priority booking so you’re less likely to get stuck waiting when demand peaks. A recurring plan keeps your furnace maintenance documented, which many manufacturers require to keep the equipment warranty valid.
Plan members receive discounts that add up throughout the year:
- 20% off non-warranty repairs and parts
- 5% off new equipment and indoor air quality products
- 10% off duct cleaning

What We Do During a Professional Furnace Tune-Up
Our licensed and insured technicians work on all makes and models. A thorough maintenance visit covers the mechanical, electrical, and safety components that determine how reliably and safely your system runs through the heating season.
Inspection & Cleaning
Heat Exchanger Inspection
We check the heat exchanger for cracks or corrosion. A compromised exchanger can allow combustion gases, including carbon monoxide, to enter your living space, making this one of the most important steps in the process.
Burner & Flame Sensor Cleaning
Dirty burners and a fouled flame sensor are common causes of ignition problems and incomplete combustion. Cleaning both supports reliable startup and cleaner fuel use.
Blower, Motor & Mechanical Components
We inspect the blower motor and belt, lubricate moving parts, and verify that airflow is moving through the system as designed.
Safety & Calibration Checks
Electrical & Safety Checks
We check all electrical connections, run a carbon monoxide and gas leak safety check, and verify the system shuts down safely when it should.
Filter Inspection & Thermostat Calibration
We inspect and replace the filter as needed, then calibrate the thermostat to confirm the system activates and deactivates at the correct temperatures.
The Benefits of Annual Heating Maintenance
Skipping a year of furnace maintenance rarely causes an immediate problem. The consequences tend to show up later, during the coldest stretch of the season or as a gradual rise in your monthly heating bill.
A clean, well-calibrated furnace can use less fuel to hold the target temperature, which can mean lower heating costs. Regular maintenance also gives a technician the chance to catch worn components, dirty sensors, or restricted airflow before they become a breakdown, which can help keep repair costs down over time. Systems that receive consistent professional care typically last longer than neglected ones, which can push back the timeline on replacement. And because dust and debris inside the furnace circulate through your home’s air supply, cleaning the system also supports better indoor air quality throughout the heating season.
Same-day and weekend appointments are available, and free diagnostics and estimates are included. Call us at (510) 974-7107 to schedule your furnace maintenance in San Jose or learn more about the Costless Comfort Protection Plans.
