Expert Heating Repair in Temple City, CA

A furnace that won't ignite, a heater that cycles on and off repeatedly, or cold rooms that refuse to warm up - these are fixable problems, not reasons to replace your whole system. Our Temple City heating repair technicians diagnose the real root cause and repair it precisely.

Common Heating Failures We See in Temple City

  • Hot Surface Igniter Failure: The most frequent furnace repair in modern gas systems. The igniter glows red-hot to light the burners - when it cracks from thermal cycling, you get no heat at all. We carry universal and OEM igniters on every service van.
  • Dirty Flame Sensor: Carbon deposits on the sensor rod cause the furnace to light and then immediately shut off within seconds. A simple cleaning often resolves this completely in one visit.
  • Inducer Motor Failure: The draft inducer motor pulls combustion gases out of the heat exchanger. When it fails, the pressure switch trips and locks the furnace out - no heating until it's repaired.
  • Bad Control Board: The circuit board governs the entire ignition sequence. Failed boards cause random shutdowns, failure to ignite, or continuous blower operation with no heat.
  • Cracked Heat Exchanger: A safety-critical failure that can allow carbon monoxide to enter your living space. Always requires immediate system shutdown and replacement of the heat exchanger or full unit.

What You Can Try Before Calling

A few quick checks before calling for heating repair: make sure your thermostat is set to HEAT and the temperature is set above the current room temperature, check that the furnace power switch (looks like a light switch on the wall near the unit) is in the ON position, verify the circuit breaker for the furnace hasn't tripped, and replace your air filter if it's visibly clogged - a completely blocked filter can cause the furnace to overheat and shut off on its safety limit. If all of these are normal and the problem persists, call us.

Honest Diagnostics, Not Guesswork

Our technicians use combustion analyzers, manometers, and digital multimeters to identify the exact root cause of your heating failure - not just the first component that looks questionable. We check the entire control sequence from the thermostat signal all the way through ignition, burner operation, and heat exchanger integrity before making any recommendation. If we suspect a cracked heat exchanger, we'll show you with an inspection camera. We believe in transparency - you see exactly what we see.

Our Heating Repair Process

We diagnose thoroughly and repair precisely on every Temple City heating call:

  • 1. Full Control Sequence Test: We verify the thermostat signal, draft inducer operation, pressure switch continuity, igniter resistance, flame sensor microamp reading, and all rollout/limit switches.
  • 2. Gas Pressure Verification: We connect a digital manometer at the manifold to confirm the gas valve is supplying the correct pressure to the burner assembly.
  • 3. Heat Exchanger Inspection: We use a flexible inspection camera and combustion analyzer to check for cracks or signs of incomplete combustion.
  • 4. Written Flat-Rate Quote: Every repair price is provided in writing before the work begins. No exceptions.
  • 5. Post-Repair CO Test: We test for ambient carbon monoxide after every gas heating repair before considering the job complete.
