Local considerations
A furnace that has sat idle through the Cambridge cooling season accumulates dust on the flame sensor. The resulting lockout after three ignition attempts reads like a failure but is far more often a cleaning job.
Long cold winters and widespread boiler heating make pressure, circulator and zone valve faults frequent. For Cambridge that means the first genuinely cold night of the season produces a cluster of calls from systems that were fine in October.

Furnace Repair in Cambridge
Freeze risk makes a furnace failure urgent rather than inconvenient, and a burner that has sat idle all summer fouls its flame sensor before the first cold snap.

02 Furnace Installation and Replacement in Cambridge
Rising fuel bills combined with longer run times are the quiet signal that a furnace is losing efficiency and the replacement clock is running.
Details
03 Heat Pump Repair in Cambridge
Auxiliary heat covers the shortfall when outdoor temperatures drop far enough that the heat pump cannot keep up alone, which is by design, not a failure.
Details
04 Boiler Repair in Cambridge
Pressure that drops overnight means there is a leak somewhere in the loop, and finding it before the pipes freeze is a different category of urgency than a summer repair.

What is your thermostat reading?
Drag the dial to the temperature your thermostat shows now. The readout names the likely cause band, how urgent it is, and which page to read next.

- Likely cause band
- Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.
- Urgency
- Call today
- Read next
- AC not cooling
What to do while you wait
- Switch the thermostat off so the system stops attempting ignition over and over.
- Confirm the gas supply valve is open and that a service switch has not been knocked off.
- Check the filter. A blocked one makes the furnace overheat and shut itself down.
- Keep interior doors open so the warmth remaining in the house distributes evenly.

Cambridge HVAC questions
How many ZIP codes do you cover in Cambridge?
We list 6 ZIP code areas across Cambridge for heating work. Each routes to independent providers covering Middlesex County. If yours is missing, calling still works because the operator can check provider coverage directly.
Can someone come out tonight?
The line is answered 24/7 in ET. Whether a provider can reach Cambridge overnight depends on participation, technician availability and demand, which spikes during cold snaps. The operator tells you the realistic window rather than guessing.
Is there a charge to call?
No. There is no charge to call and no obligation to proceed. We may be compensated by providers or partners when you call, which does not affect what you pay. The provider quotes their own price before any work starts.
What heating systems do you cover in Cambridge?
Gas and electric furnaces, boilers, heat pumps running in heating mode, and the controls that operate them. Mention which you have when you call, because combustion work and refrigerant-cycle work need different parts on the truck.
Why is my heat pump running constantly?
A heat pump that never cycles off is usually low on charge, iced on the outdoor coil, or leaning on auxiliary resistance heat because the reversing valve is not completing the switch into heating mode.
