Heating maintenance
Why heating system maintenance matters before winter
A furnace that sat idle all summer is asked to work on the first cold night. A maintenance visit catches the small stuff before it becomes a no-heat call.
Regular heating maintenance keeps airflow clear, confirms safe ignition and venting, and gives you a plain-English look at the condition of your system. At Thomson AC, every visit is documented with photos and video so you can see what we see.
Heater already broken? Start with furnace repair. Looking for pricing on seasonal visits? See our $99 tune-up and $159 maintenance visit.

Benefits
What regular heating maintenance actually does
The goals are simple: safer operation, steadier comfort, and fewer surprise breakdowns.
Clearer airflow and efficiency
Dirty filters and restricted coils make the system work harder. Cleaning and filter service help heat move through the house the way it should.
Safer ignition and venting
We check burners, ignition, safety controls, and venting that applies to your equipment so the system starts cleanly and exhausts properly.
Problems caught early
Loose wiring, a weak flame sensor, or a failing blower show up on a quiet maintenance visit more often than on a freezing night.
A documented record
Photos and short videos of readings and findings give you a clear record for your home, not just a verbal summary.

On the visit
What we check on a heating maintenance visit
Exact steps depend on your equipment. On a typical gas furnace visit we cover:
- Filter condition and replacement when needed
- Burners, ignition, flame sensor, and safety controls
- Heat exchanger visual condition
- Flue and vent operation when it applies
- Blower assembly, airflow, and thermostat operation
- Temperature rise and overall system operation
- Photos and video of findings, reviewed with you before any extra work
Heat pumps and electric systems get the heating checks that apply to those designs. We confirm scope before work begins.

Maintenance vs. repair vs. replacement
Book maintenance when the system still heats and you want it ready for winter. Call for repair when it will not start, blows cold, cycles oddly, or makes new noises.
If a repair quote lands over about $1,000 on an out-of-warranty furnace, we will also show you replacement numbers side by side. Most furnace replacements we install run $4,500 to $5,700, about $5,100 typical. The replacement estimate is free, and Goodleap financing is available for homeowners who qualify.

FAQ
Heating maintenance questions
What does a heating maintenance visit include?
We check filters, burners or heating elements, ignition and safety controls, the heat exchanger when it applies, venting, the blower, thermostat operation, and airflow. We document the visit with photos and video and review findings with you before any extra work.
How much does a furnace tune-up cost?
Our $99 tune-up is a quick, inspection-based visit with a filter change and visual check. The $159 maintenance visit is more detailed: outdoor coil rinse when it applies, drain line flush, readings, and video of the system. See our residential maintenance plan page for details.
Is a diagnostic visit the same as maintenance?
No. If your heater is already broken, that starts as a paid diagnostic visit. We find the cause, show you photos and video, and give you the price before any repair work. Maintenance is for systems that still run and need a seasonal check.
When should I schedule heating maintenance?
Before the first cold stretch is best, usually in fall. If your system also cools your home, many homeowners also book a cooling maintenance visit before summer.
Do you offer free estimates on repairs?
Diagnosis is paid. Replacement estimates are free. If a repair quote is over about $1,000 on an out-of-warranty furnace, we will also talk through whether replacement makes more sense, with a free replacement estimate.
