Furnace Service
Furnace Service & Tune-Up
Annual maintenance keeps your furnace running safely and efficiently — and helps you avoid costly mid-winter breakdowns.
Preventive Maintenance That Pays for Itself
Most furnace breakdowns are preventable. An annual tune-up catches worn parts, dirty burners, cracked heat exchangers, and safety issues before they become expensive emergencies — or worse, a carbon monoxide hazard. Our comprehensive service includes a full inspection, cleaning, and performance test so you head into heating season with confidence. Customers on our annual service plan also receive priority scheduling and qualify for our lifetime labor warranty on repairs.

Frequently Asked Questions
How often should I have my furnace serviced?
We recommend annual maintenance — ideally in the fall before heating season. Regular service keeps your system efficient, extends its lifespan, and catches small issues before they become costly repairs.
What does a furnace tune-up include?
Our tune-up covers a full inspection of the heat exchanger, igniter, burners, blower motor, filters, flue, and all safety controls. You receive a written summary of findings and any recommended repairs.
Will skipping maintenance void my warranty?
Most manufacturers require annual professional maintenance to keep the warranty valid. We document every service visit so you have proof if needed.
How much does a furnace tune-up cost?
Call us at 425-610-6635 for current pricing. We offer competitive rates and service plan options that include annual maintenance plus priority scheduling.
Can you service my furnace if it's a brand I don't see listed?
Yes — we service all major makes and models. If you have a less common brand, call us and we'll confirm availability.
What is a heat exchanger and why does it matter?
The heat exchanger is the component that separates combustion gases from the air circulating through your home. A cracked heat exchanger can allow carbon monoxide to enter your living space — which is why annual inspection is so important.
