Common furnace repair issues we solve in Whittier

Furnace won't ignite

Flame sensor fouling (80% of calls), failed ignitor, or gas valve lockout. We clean + test sensor output with meter first.

Short-cycling every 2-3 minutes

Dirty flame sensor, restricted return airflow, or failing pressure switch. We verify all three on the first visit.

Pilot light won't stay lit

Thermocouple failure or pilot orifice blockage. On 20+ year-old units, we also walk through replacement pricing.

Strange smells during operation

Dust burn-off (normal first use of season), gas leak (emergency), or overheated wiring (fire risk). We test gas pressure + sniff for mercaptan.

Blower runs but no heat

Sequencer failure on electric furnaces, gas valve issue on gas, or failed igniter/flame sensor. All diagnosed with multimeter readings.

Frequently asked — furnace repair in Whittier

Why is my furnace short-cycling?

The usual causes: dirty flame sensor, failing pressure switch, restricted return airflow, or oversized equipment. We verify all four on the first diagnostic visit.

Can you service my furnace this week in Whittier?

Same-day service for emergencies (no heat, gas smell). Routine service typically within 48 hours.

Do you test for carbon monoxide?

Yes — every furnace call gets a calibrated CO meter test. If we find unsafe levels, we red-tag the unit, inform the gas utility, and won't put it back in service until it's fixed.

What SEER2 rating should I buy in Whittier?

14.3 SEER2 (the 2023 federal minimum) saves vs. a 10+ year old unit. Going to 17 SEER2 pays back in 6-8 years on Whittier's cooling hours. Above 20 SEER2 only pays back if you stay in the home 12+ years.

What is the best thermostat setting for energy savings?

Set your thermostat to 68°F in winter and 78°F in summer when home. A programmable or smart thermostat can automatically adjust temperatures when you're away or sleeping, saving 10–15% on energy costs. {company} installs and configures smart thermostats.
