Furnace Repair & Service in Ralls, TX

The most common causes are a cracked hot surface igniter, a dirty flame sensor, a blocked pressure switch hose, or a failed inducer motor. Modern furnaces store fault codes that point directly at the failure, which is where our technicians start.

It means the furnace heats up too fast, hits the high limit, and shuts off before satisfying the thermostat. It is nearly always an airflow restriction. Fixing the limit switch without correcting airflow just delays the next failure.

Yes. A cracked exchanger can allow combustion gases into the supply air. If we find one in a Ralls home we will show you the evidence and recommend shutting the furnace down until it is replaced.

Fifteen to twenty years is typical in Ralls, since Texas furnaces run relatively few hours compared with the air conditioning side. Neglected units and units in hot attics tend to fall at the lower end of that range.

Yes, along with dual-fuel systems that pair a heat pump with a gas furnace. Each type has a different failure profile and our technicians carry the common parts for all of them.

Yes, and no-heat calls in Ralls are treated as priority work during cold weather. Call (833) 435-6611 and describe the situation, especially if there are children, older adults, or exposed plumbing in the home. See heating repair in Ralls.

Ice on the coil means either airflow is restricted or refrigerant charge is low. A clogged filter, a dirty blower wheel, closed vents, or a collapsed duct will do it. So will a refrigerant leak. Repeatedly thawing and restarting the system without finding the cause puts the compressor at risk.
