What matters for ignition repair in Marlborough
Idle summers
Dust and residue build up while the furnace sits unused. The first start of the season reveals weak igniters and dirty sensors.
Humidity in basements
Damp basements can corrode electrical connections and grounds that flame sensing depends on.
Older furnaces
Some older furnaces still use standing pilots or older ignition modules that need specific parts.

Ignition repair in Marlborough: questions
How do I know it's the flame sensor?
If the burners light for a few seconds and then go out, and this repeats, a dirty flame sensor is the most likely cause.
Why does a flame sensor get dirty?
Combustion leaves a thin film on the rod over time. Annual service usually prevents the problem.
