Local considerations
Heating equipment replacement in Princeton normally needs a permit from the local building department, and venting is usually the part that gets inspected. The provider typically handles the permit as part of the job.
Boiler systems in older Princeton homes frequently carry mineral scale inside the heat exchanger, degrading efficiency without a fault code. A descaling visit addresses it before the efficiency loss becomes a comfort complaint.

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.

- AC not cooling
What to do while you wait
- Shut the thermostat off so repeated failed ignition cycles stop.
- Note any error code flashing at the furnace control board. It shortens the diagnosis.
- Fit a clean filter if the current one is visibly dirty.
- Protect pipework in unheated spaces if the temperature is near freezing.

Princeton HVAC questions
What heating systems do you cover in Princeton?
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.
Do I have to be home?
Yes. The technician needs access to the thermostat and the equipment itself, and someone has to approve the quoted price before work begins. For combustion appliances they may also want to check alarms.
What does heating repair cost in Princeton?
We do not quote prices. The provider who attends confirms the price on site before work begins. Boiler and heat pump work generally takes longer to diagnose than a straightforward furnace fault.
What should I do before the provider arrives?
Set the thermostat to off rather than leaving it calling for heat against a locked-out system, replace a loaded filter, and close off unused rooms. Keep anyone vulnerable in the warmest part of the house.
