If your furnace keeps shutting off before the house is warm, it is short cycling. Our Pasadena technicians diagnose overheating limit switches, dirty flame sensors, clogged filters, blocked flues and thermostat faults, and repair the real problem rather than resetting the unit.
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.

Linda T., PasadenaTwo other companies told me I needed a whole new system. These guys found a refrigerant leak, repaired it and my 8-year-old unit is cooling like new. Honest people.
Jennifer L., PasadenaThe technician was on time, wore shoe covers, showed me the failed part and explained the repair versus replace math. Fair price and no pressure.
Susan K., PasadenaYes. 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.
