Local considerations
A furnace that has sat idle through the Fresno cooling season accumulates dust on the flame sensor. The resulting lockout after three ignition attempts reads like a failure but is far more often a cleaning job.
Mild coastal winters understate heating demand inland and at elevation, where overnight lows drop well below freezing. In Fresno that makes the heating season a test of whatever deferred maintenance the summer covered up. Equipment that held on through a mild spell often cannot manage a sustained cold stretch.

Furnace Repair in Fresno

02 Furnace Installation and Replacement in Fresno
Rising fuel bills combined with longer run times are the quiet signal that a furnace is losing efficiency and the replacement clock is running.
Details
03 Heat Pump Repair in Fresno
Ice on the outdoor unit in heating mode is expected briefly during defrost, but continuous icing means the defrost cycle has failed.
Details
04 Boiler Repair in Fresno
Circulator pump failure stops the heated water from reaching the radiators. The boiler may fire and reach temperature while every room stays cold.

05 Thermostat Installation and Repair in Fresno
Short cycling in heating mode stresses the heat exchanger through repeated thermal shock, making thermostat problems worth addressing promptly.

06 HVAC Maintenance and Tune-Up in Fresno
Heat exchanger inspection during a tune-up is the one check that cannot wait until a fault appears, because cracks create carbon monoxide risk before the system stops heating.

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.

- Likely cause band
- Cooling capacity loss: dirty coil, low refrigerant charge from a leak, or a failing capacitor.

- Call today
- Read next
- AC not cooling
What to do while you wait
- Shut the thermostat off so repeated failed ignition cycles stop.
- Note any error code flashing at the furnace control board. It shortens the diagnosis.
- Fit a clean filter if the current one is visibly dirty.
- Protect pipework in unheated spaces if the temperature is near freezing.

Set the thermostat to off rather than leaving it calling for heat against a locked-out system, then call. Repeated failed ignition cycles do no good and occasionally do harm.

Fresno HVAC questions
My furnace locks out after three tries. What is that?
Three failed ignition attempts followed by a lockout usually means the flame sensor is dirty, the igniter is weak or gas pressure is wrong. After a long idle summer, cleaning resolves it more often than replacing parts does.
Is a cracked heat exchanger repairable?
No. A cracked heat exchanger is a carbon monoxide risk rather than a comfort fault, and the correct response is replacement of the furnace. Any provider suggesting a patch on one is giving you poor advice.
Can I run a space heater meanwhile?
Portable heaters carry their own fire risk and should never be left running unattended or near fabric. Never use a gas range or an outdoor appliance to heat a room, which is a direct carbon monoxide hazard.
Do I need a carbon monoxide alarm?
If any gas appliance runs in the home, yes. Carbon monoxide is colourless and odourless, and a working alarm near sleeping areas is the only reliable warning. If one sounds, leave the building and call 911 from outside.
Do you work on boilers in Fresno?
Yes, where a provider covering your ZIP code handles them. Boiler faults run to pressure loss, circulator pumps, expansion tanks and zone valves, which is a different skill set from forced-air work. Say so when you call.
