Frequently Asked Questions About Furnace Repair in Castro Valley, CA

The draft inducer is a small motorized fan that turns on before the burners ignite. Its purpose is to pull combustion air through the heat exchanger and expel toxic exhaust gases safely out the flue vent. A pressure switch verifies that this draft is established; if the inducer motor fails or the vent is blocked, the furnace will lock out as a safety precaution.
Yes. The flame sensor sits directly in the burner flame and generates a micro-amp electrical current when heated to prove to the control board that fire is present. Over time, silica and carbon coat the metal rod, preventing flame detection and causing the furnace to shut off its gas valve after 3 to 5 seconds. Cleaning or replacing this sensor is a routine, fast repair for our Castro Valley, California specialists.
Cold air discharge usually points to an extinguished pilot flame, an oxidized flame sensor rod that shuts down the gas valve after a few seconds, an overheated heat exchanger tripping the high-limit switch, or an ignition lock-out. Our certified technicians in Castro Valley, California utilize digital multimeters and combustion testers to pinpoint the exact failure point and restore comfortable heat.

What Homeowners Say About Our Service in Castro Valley
"We had an annoying buzzing sound coming from our furnace control board whenever heat was called. The technician diagnosed a failing 24V transformer and relay contactor in our Castro Valley, California home. Replaced both parts quickly at a very fair rate. Couldn't ask for a smoother experience."
"We have an older oil-to-gas converted furnace that many companies refuse to touch. The senior tech from Local Furnace Repair Pro in Castro Valley, California knew exactly how the system was configured, adjusted the gas manifold pressure, and tuned the air-fuel mixture to perfection. Truly knowledgeable pros."
"Another heating contractor told us our twelve-year-old gas furnace had a cracked heat exchanger and quoted over seven thousand dollars for a replacement. We called Local Furnace Repair Pro for a second opinion here in Castro Valley, California. Their tech performed a thorough camera inspection, showed us the heat exchanger was completely sound, and fixed a stuck pressure switch for a modest fee. Honest contractors are rare gems!"
