01Heating & furnace repair
Expert heating & furnace repair in Sacramento — Cold house.
Hot answer.
When a Sacramento cold snap drops the house into the 50s indoors, you don’t want a two-week wait or a hard sell. We diagnose, quote, and fix on the spot — most repairs finish in a single visit.
We regularly repair systems other companies tried to sell. If a fix is the right call, that’s what we recommend.
02When to call
Common heating problems and warning signs — Don’t wait — these mean call now.
Heating problems get worse fast, and a few of them are actual safety issues. If your system does any of this, pick up the phone.
Won’t turn on
Thermostat shows heat-on, the unit doesn’t respond. Usually ignition control, blower, or a tripped safety.
CO detector triggered
Carbon monoxide alarm? Stop using the system and call. This is a safety call, not a comfort call.
Runs but blows cold
Burner ignition issue, gas valve, or flame sensor. The system is trying — it just can’t finish the cycle.
Odd noises
Banging, rumbling, or whining usually points to a delayed ignition, a cracked heat exchanger, or a failing inducer.
House never warms up
Thermostat set high, system runs constantly, rooms stay cold. Often duct loss, blower speed, or undersized equipment.
Gas or burning smell
Faint dust on first burn is normal. Gas, sulfur, or persistent burning is not — call before running again.
