How Much Does Furnace Maintenance Cost?

A single-system furnace tune-up runs $80 to $200 here. What changes the number is what is actually included — and whether anyone opens the burner compartment.

The short answer

$80–$200

A straight tune-up sits at the low end. Combining it with your AC visit, or a furnace that has gone years without service, moves it up.

Typical industry ranges for Western Washington — not a quote. Your exact price comes upfront, before any work starts, and you approve it first.

What moves the price

1

What is actually included

A real tune-up pulls and cleans the flame sensor, checks the igniter, inspects the burners and heat exchanger, tests gas pressure and reads combustion. A "filter and a glance" is cheaper and worth less.

2

One visit or both systems

Doing the furnace alone costs less than a visit; having the AC done in the same trip costs less than two separate visits.

3

Age and how long since the last one

A furnace serviced every fall is quick. One that has not been opened in six years takes longer and often finds something.

4

When you book it

September and October are the rush. Booking before the first cold snap gets you a normal appointment instead of an emergency one.

Book it before the first cold night.

Furnace maintenance in September catches the parts that fail in December. Exact price upfront.

Quick answers

Is furnace maintenance actually worth it?

The parts that fail in a cold snap — flame sensors, igniters, pressure switches — are the ones a tune-up finds while they are still cheap. One prevented no-heat call pays for several years of it.

How often should a furnace be serviced?

Once a year, before the heating season. If the furnace is also your AC air handler, it gets airflow attention twice a year.

Do you have to be the one who installed it?

No. We service every major brand at any age, whoever put it in.
