A Charlotte repair call

Not a cracked heat exchanger. A $400 igniter.

A homeowner in Wake Forest called us last December about a furnace that wouldn't stay on, runs for a few minutes, shuts down, then fails to relight. Another company had already been out and recommended replacement with a "cracked heat exchanger" diagnosis. The quote was just under $7,500.

We came out with a $77 diagnostic. Heat exchanger inspected with a borescope camera, flame characteristics observed, combustion analyzed, gas pressure verified at the manifold. The heat exchanger was intact, no crack, no soot pattern, no flame rollover.

What was actually wrong: the hot-surface igniter was on its last legs, lighting some cycles and failing others. The flame sensor was also coated with combustion residue, which can mimic a "system shutting down for safety" pattern.

Igniter replacement plus flame sensor cleaning came in just under $400, the $77 diagnostic credited toward the work. The furnace ran through the rest of the winter without an issue.

Cracked heat exchanger is the most common upsell in residential HVAC.

If we ever tell you the heat exchanger is cracked, we'll show you the picture.

If we can't see a crack, we don't condemn the part.

The standard, every job

We don't guess. We test.

Every furnace call starts with the gauges, the borescope, and the combustion analyzer. We don't condemn parts we haven't inspected. The truth, in writing, before any work begins.

Common furnace questions

Furnace service, plain answers.

The questions Charlotte homeowners ask most often before booking furnace repair, replacement, or seasonal care.

See all FAQs →

My furnace won't ignite. What's the most common cause?

A few common ones, in rough order of frequency: dirty flame sensor (lights and then shuts down within seconds), aging hot-surface igniter (intermittent ignition), thermostat or wiring issue, gas pressure problem, and rarer faults like a closed limit switch or a control board failure. The $77 diagnostic identifies which one and quotes the repair flat-rate before any work begins.

Will you tell me I need a new furnace if I don't?

No. The "cracked heat exchanger" diagnosis is the most common HVAC industry upsell pattern. If we ever say the heat exchanger is cracked, we'll show you the photo from the borescope, in person or emailed. If we can't see a crack, we don't condemn the part. Repair stays the recommendation as long as the math works.

What brands do you work on?

We service every major brand, Carrier, Trane, Lennox, Rheem, Goodman, Amana, Daikin, York, Bryant, American Standard, Heil, and more. For new furnace installs, we primarily install Daikin and Goodman. Repair work covers the full market regardless of brand.

When should I get a furnace tune-up?

October is ideal. The first cold snap in the Triangle usually arrives mid-November, and finding a problem in October beats finding it at 7 a.m. on the first 22-degree morning when every other HVAC company is also slammed. Cardinal Club members get the pre-winter tune-up as one of their two annual visits.

Do you offer financing on new furnace installs?

Yes. We finance through GreenSky. Most install customers are pre-approved before the install date. Pricing is quoted in writing after a free in-home consultation that includes a Manual J load calculation, sizing the furnace to your home's actual heat load, not a sales target.

Heat that holds, done right.
