COMMON HEATING PROBLEMS
When Your Furnace or Heater Isn't Working Right
Heating problems can come from ignition, airflow, thermostat, electrical, gas-control, safety-control or equipment issues. A proper diagnosis helps determine what actually needs attention.
No Heat
The system may run without producing enough heat, or the furnace may fail to start at all.
Furnace Won't Ignite
Ignition problems may involve the igniter, gas valve, pressure switch, safety circuit or control system.
Starts Then Shuts Off
Short run times can be related to flame-proving, overheating, airflow restrictions or safety controls.
Thermostat Problems
Incorrect settings, wiring, control faults or thermostat failure can interrupt normal heating operation.
Blower Problems
A blower that does not start, runs continuously or provides weak airflow can affect comfort and safety.
Pressure Switch Issues
Draft and pressure-switch faults can stop the furnace sequence before ignition is allowed.
Flame Sensor Issues
If burners ignite and then shut off after a few seconds, the flame-proving circuit may need attention.
Safety Control Faults
Limit, rollout and other safety devices can shut the system down when unsafe operating conditions are detected.
DIAGNOSE BEFORE REPAIR
We Check the Heating Sequence Before We Recommend Repairs.
A heating problem does not automatically mean you need a new furnace. We inspect the sequence of operation, electrical components, safety controls, ignition system and heating performance to identify the cause before discussing your options.
Ignition & Flame Proving
Evaluate the igniter, flame sensor, gas ignition sequence and related controls.
Safety Controls
Check pressure-switch, limit, rollout and other safety circuits related to the reported problem.
Airflow & Heating Performance
Evaluate blower operation, airflow and how the system is delivering heat to the space.

The technician evaluates the furnace or heating system based on the symptoms and operating conditions found.

06
Know What Was Done
We want customers to understand what was found and what work was performed on the system.
REPAIR OR REPLACEMENT?
Diagnosis Comes First.
A no-heat call does not automatically mean the furnace needs to be replaced. We first identify the actual failure and then discuss the practical repair or replacement options.
STRAIGHTFORWARD RECOMMENDATIONS
Know What Your Heating System Needs Before Making a Decision.
If a repair makes sense, we can discuss the repair. If the equipment condition, age or repair cost makes replacement worth considering, we can explain that option separately.
