A furnace that will not light, blows cold air, or keeps shutting off on its own needs a real diagnosis, not a guess, whether it is heating a century-old Craftsman or a postwar tract home. Our licensed technicians find the actual cause and get most Pasadena heating repairs done the same visit.
A furnace that has not run since last spring can develop problems that only show up the first cold night you switch it back on. These are the signs worth acting on before you are stuck without heat in Pasadena.
A repeated clicking sound with no flame usually points to a failing ignitor. Ignitors typically last around seven years and are one of the most common furnace parts to fail, especially in a system that only runs a few months a year.
Century-old Craftsman homes near the Arroyo Seco often have ductwork added decades after construction, routed around original plaster and woodwork, which can leave a furnace unable to distribute heat evenly through a distribution system that was never original to the home.
A furnace that turns on and off every few minutes instead of running a full cycle is often overheating internally, sometimes from a dirty filter, a blocked vent, or a failing flame sensor. Left alone, it wears down other parts faster.
A healthy gas flame burns blue and steady. A yellow, orange, or flickering flame can mean incomplete combustion, which is a genuine safety concern and should be looked at right away, not scheduled for later in the week.
Some rooms warm, others cold, regardless of the thermostat setting, often points to a thermostat calibration issue, a duct problem, or a blower struggling to move air through the whole system evenly.
A brief dusty smell on the season's first run is normal. A persistent burning smell, or anything resembling rotten eggs, is not. Turn the system off and call for service immediately rather than waiting it out.
Pasadena's housing spans more architectural eras than almost anywhere else we serve. The city was founded in 1874, and Craftsman bungalows near the Arroyo Seco, Old Pasadena commercial buildings from the late 1800s, and postwar tract homes all sit within a few miles of each other. A century-old Craftsman with a furnace and ductwork added long after construction fails differently than a postwar home built with heating in mind from the start, and treating a century-plus of architecture as one uniform housing stock is how repairs get misdiagnosed.
The same mild-until-it-isn't pattern that affects furnaces elsewhere in LA applies here too. A system that sat idle since spring has to work correctly the first time it gets called on, and ignitors that were already wearing down often fail exactly then. A cracked heat exchanger is a genuine safety issue regardless of a home's age or era, and it is exactly the kind of problem a pre-winter tune-up is designed to catch before the system runs through a real cold snap.
Before anything else, we check for gas leaks, verify flame color, and inspect the heat exchanger, since heating repair involves combustion safety that AC repair does not.
You get a clear price before any repair starts, based on what we actually find, not a guess made over the phone.
Most common repairs, ignitors, flame sensors, thermostats, are completed in the same visit with parts we carry on the truck.
We run the furnace through a complete heating cycle and confirm proper airflow and even temperature before we leave.
Every repair gets a written estimate before work starts. These are typical ranges for the most common heating repairs we perform in Pasadena, not a final quote.
