What furnace repair involves
A gas furnace runs a fixed sequence: thermostat call, inducer fan, pressure switch, ignition, flame sensing, then the blower. A failure at any step stops the heat, and many furnaces blink an error code that points to the step.
Oil furnaces work similarly but use an oil burner with a pump, nozzle and ignition transformer, and need regular nozzle and filter changes.
The technician follows the sequence, tests each part and repairs the failure, then checks venting, gas pressure or oil burner operation and carbon monoxide.

Furnace repair in Marlborough: local context
Marlborough sits where Route 20 meets I-495, with a historic downtown, older neighborhoods of capes and colonials, and newer subdivisions and condo complexes built as the city grew along the highway.
Forced-air furnaces are common in the city's mid-century and newer homes, fueled by natural gas or oil, and many homes add central air through the same ductwork. Older homes may still have boilers, and more owners are adding cold-climate heat pumps.

Furnace Repair: common questions
What does the blinking light on my furnace mean?
Most furnaces have a code chart inside the door. The blink pattern points to the part of the sequence that failed. Tell the technician the code when you call.
Can a furnace be repaired the same day?
Often. Igniters, flame sensors, pressure switches and some boards are commonly carried. Some parts must be ordered.
