Filter Check & Replace
We check your air filter and replace it as needed so airflow, efficiency, and indoor air quality stay where they should be.
Burner & Ignition Test
We test the burners, igniter, and flame sensor and clean as needed for a strong, clean, reliable light every heating cycle.
Blower & Airflow Cleaning
We clean the blower assembly and check airflow so your furnace heats evenly and doesn't have to work harder than it should.
Thermostat Calibration
We verify and calibrate your thermostat so the temperature you set is the temperature you actually get, room to room.

Furnace Maintenance Questions, Answered
How often should I service or tune up my furnace?
At least once a year, ideally in fall before heating season. An annual tune-up keeps your furnace efficient and safe, lowers bills, prevents breakdowns, checks for carbon monoxide, and helps keep your warranty valid. Club Zen members get annual inspections and priority scheduling.
What's included in a furnace tune-up?
A safety and heat-exchanger inspection, a carbon-monoxide and gas-connection check, a filter check or replacement, burner and ignition testing, blower and airflow cleaning, thermostat calibration, and an efficiency and performance check — then we walk you through anything we found.
Can I schedule maintenance in the off-season?
Absolutely. Late summer and early fall are ideal — you beat the pre-winter rush and head into heating season ready. That said, we tune up furnaces any time of year, and Club Zen members get priority scheduling.
Does maintenance keep my warranty valid?
Usually, yes. Most manufacturers require documented annual maintenance to keep the parts warranty valid — skipping it can void coverage. A yearly tune-up protects both your comfort and your investment.
How often should I change my furnace filter?
Every one to three months during heating season, depending on usage, pets, and dust. A clean filter improves airflow, efficiency, and air quality, and protects the blower and heat exchanger between professional tune-ups.
What are the signs my furnace needs maintenance?
Rising energy bills, weak or uneven airflow, short cycling, unusual noises, dusty air, or simply not having it serviced in over a year. A tune-up catches small issues early, before they turn into a cold-night breakdown.
Is furnace maintenance really worth it?
Yes. It lowers your energy bills, prevents most surprise breakdowns, extends the life of your system, keeps it running safely, and protects your warranty — one of the highest-value things you can do for your home comfort. Club Zen makes it effortless.
