Frequently Asked Questions

What is a flame sensor and why does it fail?
A flame sensor is a small rod that confirms the burner has ignited before allowing gas to continue flowing. It accumulates oxidation over time and must be cleaned or replaced periodically. A failed sensor causes the furnace to start and immediately shut off.
We prioritize same-day service for emergency calls throughout Kane County. Contact us early in the day for the best chance of same-day service. Urgent situations — especially in households with young children or elderly residents — are always given priority.
Yes. We service high-efficiency condensing furnaces including diagnosis and repair of pressure switches, inducer motors, condensate systems, and modulating gas valves. We work on all efficiency ratings and major system types.

Pressure switch faults are often caused by a clogged condensate drain line, a blocked flue or intake pipe, a failed inducer motor, or a cracked pressure switch hose. Each cause requires a different fix, which is why accurate diagnosis matters.

Call a technician if your furnace short-cycles, blows cold air, makes new or unusual sounds, or if your energy bills have risen without a change in usage. Early service prevents small problems from becoming expensive failures during the coldest weeks.
