A minor ignition fix costs far less than a failed blower motor or heat exchanger issue, and the diagnosis itself is what determines everything else. Older homes near the Historic Roswell District, some running original furnaces well past 15 years old, tend to see higher repair costs simply because replacement parts for older systems can be harder to source.
Common Furnace Repairs and What Affects Their Cost
Ignition or Pilot Assembly Repair
Usually one of the more affordable fixes when the furnace won’t stay lit.
Blower Motor Replacement
A mid-range repair, needed when the furnace heats but doesn’t circulate air properly.
Thermostat or Control Board Issues
Cost depends on whether it’s a wiring fix or a full control board replacement.
Heat Exchanger Repair
One of the more expensive repairs, and a cracked heat exchanger is also a safety concern that can allow carbon monoxide into the home, according to the CDC, so it’s worth addressing immediately.
Heat exchanger issue or won’t stop cycling? Don’t wait on a safety-related repair.

Most companies charge a diagnostic fee that’s applied toward the repair if you move forward. This should reflect an actual inspection, not a guess based on symptoms described over the phone. If you need service outside normal hours, ask upfront about after-hours availability when you book your furnace repair.
Repair vs. Replacement Cost Comparison
If a repair estimate approaches half the cost of a new system and the furnace is already 15+ years old, replacement is usually the better long-term value. A trustworthy technician will walk you through both options honestly rather than pushing whichever is more profitable.

Quick Questions
Is a cracked heat exchanger always a replace situation?
Not always, but given the safety implications and typical repair cost, replacement is often the more sensible choice depending on furnace age.
Does furnace age affect repair cost?
Yes, parts for older or discontinued models can be harder to source, which sometimes raises the cost or timeline for repair.
Is emergency furnace repair more expensive?
After-hours or cold-snap emergency calls sometimes carry a premium. Ask upfront if urgency applies to your situation.
Do I have to pay the diagnostic fee if I don’t move forward with the repair?
Policies vary by company. Ask upfront whether the diagnostic fee is waived or applied toward the repair, and get it in writing before the technician starts.
