Unexpectedly high utility costs mean your furnace is running inefficiently.
The furnace turns on and off too frequently without heating the house completely.
Little to no air is coming out of the vents.
Grinding, squealing, banging, or rumbling sounds coming from the unit.
Persistent dusty smells or, critically, a sulfuric or "rotten egg" smell (call the gas company immediately!).
If your pilot flame is yellow or flickering (instead of steady blue), it indicates incomplete combustion, which can be a serious safety hazard.
Pooling water or excessive condensation around the furnace cabinet.

The $5,000 Rule (or $5K Rule) is a simple guideline to help homeowners decide whether to repair or replace their furnace. You multiply the age of your furnace by the estimated cost of the repair.
If the total is more than $5,000, it is usually smarter to replace the entire unit than to repair it. For example: A 15-year-old furnace with a $400 repair bill ($15 \times \$400 = \$6,000$) suggests replacement is the wiser, long-term choice.
The most common cause of furnace failure is usually a dirty or clogged air filter. This restricts airflow, which causes the system to overheat and shut down (short-cycle). Other very common issues include a faulty igniter or a failed blower motor.
The cost of service starts with a diagnostic fee (usually between $90 and $150), which covers the technician identifying the problem. Once diagnosed, the repair cost is based on the specific part needed (e.g., a simple igniter replacement costs less than replacing a major heat exchanger).
We provide a transparent, written quote before any repair work begins.
