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
- Set the thermostat to off rather than leaving it calling for heat against a locked-out system.
- If you smell gas, leave the building first and call the gas utility or 911 from outside.
- Replace a loaded filter. Restricted airflow trips high-limit switches on furnaces.
- Close off unused rooms and keep anyone vulnerable in the warmest part of the house.

San Francisco HVAC questions
What heating systems do you cover in San Francisco?
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 San Francisco?
We do not quote prices.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.
