No heat after a long idle stretch
Dust and soot settle in the burner area, the flame sensor gets a film and the ignitor ages unseen. The first cold night finds the weak part.

Examples of our work
Safety first
Turn the furnace off and get help right away if you smell gas, a carbon monoxide alarm sounds, you smell burning that does not fade, or you hear loud banging. Leave the house and call 911 or your gas utility from outside.
The CPSC carbon monoxide guide explains what to do.
Common furnace problems here
Furnace lights, then shuts off
A dirty flame sensor is the usual cause. A weak ignitor is next.
Short cycling
A clogged filter or blocked registers.
A blower that will not run
A failed capacitor or motor.
Uneven heat in a split level
The warm air rises, so the upstairs overheats while the lower level stays cool.
What to know about homes here
Spring Valley has many mid century ranch homes from the 1950s through the 1970s, split levels and newer stucco and tile tract homes. In ranch homes the furnace is often in a closet or attic with original ducts, and in split levels, layout can matter more than the furnace.
If heat is uneven, we look at duct design and returns before we blame the equipment.

Repair or replace?
If the furnace is 15 or more years old, a heat exchanger is cracked or repairs are piling up, price a replacement. In a mild climate a heat pump or ductless system is also worth considering.
See furnace installation in Spring Valley and heat pump installation in Spring Valley.
Before you call, three checks that sometimes save a visit
- Confirm the thermostat is set to heat and its batteries are fresh.
- Check the filter. A clogged one can shut a furnace down.
- Make sure supply registers are open and not covered.
If none of that works, call. Tell us what you hear and smell, and we will arrive with the likely parts.
Why a furnace that sat idle fails first
A San Diego furnace may run only a few weeks a year. Between uses, dust settles in the burner area and the flame sensor builds a film, so the first cold night finds the weak spot.
A quick checkup in fall costs less than a night without heat, and it is the cheapest repair you will ever make.

Why does my furnace shut off after lighting?
A dirty flame sensor is the most common cause. Call us if a new filter does not help.
Why is my upstairs hotter than downstairs in winter?
