Professional Floor Furnace Services in Norwalk & La Mirada
Floor furnaces are gravity-fed gas heating units installed beneath the floor with a decorative grate at floor level. They were standard in homes built in the 1940s through 1960s across Norwalk and La Mirada, and many are still in service today. While they're mechanically simple — no blower motor, no ductwork, no electrical requirement on millivolt models — they do require periodic service to operate safely.
Our technicians have decades of experience servicing floor furnaces from manufacturers like Williams, Empire, O'Keefe & Merritt, and Wedgewood. We handle thermocouple replacement, pilot and burner cleaning, gas valve testing, and full floor furnace replacement when a unit is beyond economical repair. We also stock common thermocouples and pilot assemblies so most repairs happen in a single visit.
One important safety consideration with floor furnaces: the grate surface gets extremely hot during operation. We check for proper clearances and make sure heat deflectors are intact on every service call, particularly in homes with children or elderly residents.
Our Floor Furnace Service Process
Access & Initial Inspection
We remove the floor grate and access the furnace from above, inspecting the pilot, burner, thermocouple, and heat exchanger for damage, corrosion, and debris.
Cleaning & Safety Check
We vacuum out the combustion chamber, clean burner ports, check the flue connection below the unit, and test for gas leaks at all connections with a combustion gas detector.
Pilot & Thermocouple Service
We clean the pilot orifice, test thermocouple output, and replace the thermocouple if output is below spec. We test the main gas valve for proper opening and closing.
Replacement When Needed
When a floor furnace is beyond repair or parts are unavailable, we provide replacement options and handle the complete swap including gas line disconnect, new unit installation, and floor grate fitting.
