Central Valley winters bring cold, foggy mornings and nights that dip well below what most people expect from California — and an unreliable furnace makes it worse.
Many older Exeter homes also still run original ductwork, the same ducts that carry cool air in summer — so a leak or blockage there can just as easily leave rooms cold and uneven in winter.
A furnace that's sat unused all summer is exactly the kind of system that fails on the first genuinely cold night — and Central Valley fog season tends to arrive quickly. Scheduling a tune-up before then is the easiest way to catch a small issue before it becomes a no-heat emergency.
The best time to do this is before the cold actually arrives, not after a night without heat.
Common causes include a tripped breaker, a pilot light or ignition problem, a thermostat malfunction, or a safety switch that's been triggered. A technician can diagnose the exact cause.
This can point to an ignition problem, a clogged filter restricting airflow, or a thermostat set incorrectly. It's worth having it looked at rather than waiting, especially overnight.
A yearly tune-up before the cold season helps catch small issues before they turn into a no-heat emergency.
The short version: schedule a tune-up before the first cold snap, not after. A technician checks ignition components, filters, thermostat accuracy, and ductwork, so small issues get caught while the weather still gives you time to fix them.
A tune-up typically covers a check of ignition and pilot components, air filter inspection and replacement, thermostat testing, and a look at ductwork for leaks or blockages — the same components most likely to cause a no-heat call once winter sets in.
It depends on the age and condition of your current system. A furnace repair is usually the faster, lower-cost fix for an isolated issue. A heat pump is worth discussing if your system is older and you're thinking about replacement anyway, since it handles both heating and cooling in one unit. We can talk through which makes more sense for your specific situation.
