Furnace · Raleigh & Triangle
Gas, electric and dual-fuel furnace repair, installation, replacement and pre-winter tune-ups. $72 diagnostic on repairs. Free in-home consultation on new systems. Every major brand serviced.
After-hours, you reach our team. Not a voicemail.
Repair, install, replace or seasonal care. We route you to the right answer and the right appointment.
When the system won't ignite, short-cycles, throws a flame-sensor code, or just isn't keeping up. Flat-rate repair on every major brand. The $72 diagnostic credits toward the repair.
For new construction, additions, or converting electric resistance to gas. We size the system to the actual load — Manual J on every quote. Financing through GreenSky. Free in-home consultation.
When the unit is past its useful life or the repair math no longer works. We measure, recommend and quote in writing. No pressure to upgrade if the existing system has years left. Free in-home consultation.
Catch the January no-heat call before it happens. The pre-winter tune-up covers combustion analysis, heat exchanger inspection, flame sensor cleaning and ignition timing — the things generalists skip. Covered by Tru Comfort, $14.99 a month.
A few patterns we hear most in the winter. Any one of them is reason enough to schedule a diagnostic.
The thermostat is set, but nothing fires up, or it starts and quits right away.
Same usage, same thermostat, noticeably higher utility statement.
Heat blasts for a minute, shuts off, starts again. The house never quite settles.
A bedroom, a finished basement, a bonus room over the garage.
Something is preventing a clean start. Often a sensor, an igniter, or a gas-pressure issue.
Leave the house and call 911 first. Then call us so we can diagnose properly.
We diagnose properly, write the price before any work begins, and tell the truth about whether it's repair or replacement.
Same-day or next-day, most days. $72 to come out on a repair, credited toward the work. Free in-home consultation on new installs. Scheduling online takes about 90 seconds.
Every furnace call starts with the gauges, the borescope and the combustion analyzer. Here is what each one tells us, in plain language.
With a borescope camera, looking for a crack, a soot pattern or flame rollover — rather than condemning the part from the driveway.
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.
What it means: Cracked heat exchanger is the most common upsell in residential HVAC. A photograph is how you tell a diagnosis from a sales pitch.
Gas pressure verified at the manifold, flame characteristics observed, combustion analyzed on every call.
What it means: A furnace that lights and then quits is usually telling you about a sensor or an igniter, not about a system that has to be replaced.
Static pressure and airflow across the system. Undersized returns and leaking ducts cause the same cold back bedroom that a failing furnace does, and cost a great deal less to fix.
What it means: Sometimes the answer isn't a new system. If your system has years left in it, we'll say so.
A Raleigh-area repair call, last December.
A homeowner in Wake Forest called us 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 $72 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.
The igniter was replaced and the flame sensor cleaned on the same visit, the $72 diagnostic credited toward the work. The furnace ran through the rest of the winter without an issue.
What it means: Cracked heat exchanger is the most common upsell in residential HVAC. If we can't see a crack, we don't condemn the part.
| What is being compared | A typical call | A Tru72 call |
|---|---|---|
| Diagnosis | Guess first. Swap the part that usually fails and see whether it holds. | Measure first. Combustion, gas pressure and electrical draw read before anything is quoted. |
| The heat exchanger | Condemned on sight, and the visit becomes a replacement quote. | Inspected with a borescope. No photo of a crack, no condemned part. |
| Repair or replace | Replace first. A repair on an older system becomes a replacement quote. | Diagnose first. If your system has years left in it, we'll say so. |
| Sizing a replacement | Same size as the old one, right or wrong. | Manual J load calculation against your actual home — square footage, ceiling heights, windows, insulation. |
| The price | A number at the end of the visit, after the work. | Flat-rate, in writing, before a wrench turns. The $72 diagnostic credits toward it. |
What it means: An oversized furnace short-cycles and wears out in half the time. Measuring is how you avoid buying one.
Five steps, every time, whether it's a flame sensor or a heat exchanger.
Online or by phone. Same-day and next-day appointments are usually available, and after hours you reach our team.
$72 flat to come out and find the actual fault. Combustion analyzed, heat exchanger inspected with a borescope, gas pressure verified at the manifold.
The repair price in plain terms, in writing, before any work begins. The $72 credits toward it if you go ahead.
The fault gets fixed — not the part next to it. Every major brand of gas, electric and dual-fuel furnace.
We re-measure after the repair, so you know the system is performing before we leave.
We service every major brand — Carrier, Trane, Lennox, Rheem, Goodman, Amana, Daikin, York, Bryant, American Standard, Heil and more. When a furnace does need replacing, these are the two we install.
Inverter-driven, ultra-quiet, high-efficiency
Daikin is the global leader in heat pump technology, and its furnace and dual-fuel pairings carry the same engineering. Variable-speed operation matches output to demand minute by minute, so you get tighter temperature control and lower operating noise.
Solid efficiency, strong warranty, accessible price
Goodman is the workhorse of the Daikin family in North America. Systems that hit modern efficiency targets at an approachable price point, with a warranty among the strongest in the industry — which matters when the system needs to last 15 to 20 years.
What it means: AFUE is the efficiency rating on a furnace label. A higher number means more of the gas you buy ends up as heat in the house.
Most no-heat January calls are issues we'd have caught in October. Tru Comfort members get a pre-winter furnace tune-up as one of their two annual visits, plus 10% off any repair and 5% off new equipment. $14.99 a month or $180 a year, per system. Free for first responders, teachers, and military through the Mission Ready Plan.
If the diagnostic points at replacement rather than repair, this is the money that is already on the table. We check it before you commit to anything.

One system, two Carolina seasons — and the dual-fuel option that pairs with a furnace.
The same standard, the same $72 diagnostic, on the Charlotte side.
The questions Raleigh and Triangle homeowners ask most often before booking furnace repair, replacement or seasonal care.
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 $72 diagnostic identifies which one and quotes the repair flat-rate before any work begins.
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.
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.
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. Tru Comfort members get the pre-winter tune-up as one of their two annual visits.
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.
Same diagnostic discipline the family has carried since 1972. $72 to come out on a repair, credited toward the work. Free in-home consultation on new systems.
