Furnace short cycling in South San Francisco, turning on and off every few minutes, wears out parts fast and leaves the house cold. We find the cause, whether it is airflow, a flame sensor, an oversized furnace or a thermostat, and fix it for good.
Call (855) 459-5498Short cycling has two main families of causes. Overheating: a clogged filter, closed vents, a failing blower or a dirty coil makes the furnace hit its high limit and shut down. Flame loss: a dirty or cracked flame sensor, weak igniter or unstable gas pressure makes the control board cut the burners early. Less often the furnace is simply oversized for the home, or the thermostat is placed badly. We test airflow, temperature rise, flame signal and gas pressure to find which one it is.

Our AC quit during the hottest week of the year and they had a technician at our South San Francisco home the same afternoon. Fixed a capacitor, charged exactly what was quoted. Cold air within an hour.
Maria G., South San FranciscoFast response, clear explanation, and the price matched the quote to the dollar. This is who I call for furnace short cycling repair now.
Kevin O., South San FranciscoHad them out for an AC tune-up before summer. Thorough inspection, cleaned the coils, and they found a weak capacitor that would have failed in July. Smart move.
James W., South San FranciscoYes. Each start puts stress on the igniter, blower and control board, and the furnace never reaches efficient operating temperature. Fix it early and you avoid bigger repairs.
Absolutely. It is the first thing we check. A clogged filter restricts airflow and overheats the heat exchanger, tripping the limit switch.
