Open 24/7 for emergencies
A York furnace or AC repair starts with the $99 diagnostic, and most York furnace, AC and heat pump repairs run $95 to $1,500, priced in writing before anything is touched. Coleman and Luxaire too, since they’re the same family. When one is past fixing, we’ll show you why we’d put in a Trane.

Read your own York
The things people describe on the phone, what they turn out to be on a York, and what the fix costs.
The burners lit and went out, or never lit. On a York that’s usually a sooted flame sensor ($95 to $180 to clean) or a cracked igniter ($240 to $410). The board’s light will be flashing a code; the table below says which. On a York, 7 red flashes means it couldn’t light in three tries and will try again in an hour. A continuous amber light on a TM9V means the flame signal is weak: the flame sensor needs cleaning.
A furnace that keeps restarting is protecting itself: a dirty flame sensor, a clogged filter tripping the high limit, or a pressure switch that can’t prove the venting. Start with the filter. Then count the flashes.
Most of the time it’s the run capacitor ($240 to $370). Turn it off at the thermostat: a compressor that keeps trying to start against a dead capacitor can burn itself out.
In summer, ice means the coil isn’t getting enough air (a filter, a dirty blower wheel at $300 to $440) or it’s low on refrigerant, which means a leak. On a heat pump in winter, some frost is normal; a solid block of ice that never clears points at the defrost board ($450 to $1,150).
A high-efficiency furnace and every AC coil make water, and it has to drain. A clogged trap or drain line ($175 to $420 to clear, with a float switch added) is the usual answer. Water from the tank beside it is a water heater call. On a condensing York, the pressure switches also watch the condensate drain, so a clogged or frozen drain line shuts the furnace down on purpose. York’s furnace warranty doesn’t cover damage from frozen or badly drained condensate, which makes the drain worth keeping clear.
A squeal or whine is usually the inducer or the blower motor’s bearings on the way out (a blower motor runs $670 to $2,400, standard against variable speed). A bang at startup is delayed ignition: gas building up before it lights. That one needs a look soon, not next month.
A system that never shuts off is short on capacity: low refrigerant, a dirty outdoor coil, a blower wheel packed with dust, or a heat pump leaning on its backup electric heat. Each one is a price, not a guess.
Leave the house, then call the gas company from outside. Once it’s safe, call us: (703) 997-9757, 24/7.
The codes on the board
Count the red flashes through the window in the blower door; each one is on and off a third of a second. A light that stays on means the board failed, and York’s boards aren’t field-repairable. The modulating YP9C adds amber codes: four amber flashes means the airflow is restricted (a dirty filter or closed registers), five a blocked vent or a clogged condensate drain (YP9C manual).
A slow green flash is normal standby and a slow amber flash is a normal call for heat. The board keeps the last five codes, and its LAST ERROR button plays them back.
| Red flashes | What it means | What it usually takes |
|---|---|---|
| 1 | Flame sensed with no call for heat | Call: a leaking or slow-closing gas valve |
| 2 | Pressure switch closed when it should be open | The pressure switch or its wiring |
| 3 | Pressure switch open when it should be closed | The inducer, a blocked vent pipe, the pressure switch hose or the switch |
| 4 | Main limit switch opened | A dirty filter first, then the ducts, blower speed or blower motor |
| 5 | Rollout switch open (it resets by hand) | Call: combustion air, the inducer, the burners or the heat exchanger |
| 6 | Pressure switch opened four times in one call; one-hour lockout | The inducer, a blocked vent or the switch |
| 7 | No flame after three tries; one-hour lockout | Gas valve switch, gas pressure, igniter or flame sensor |
| 8 | Flame lost five times; one-hour lockout | Gas pressure, the flame sensor or the gas valve |
| 11 | Limit open more than five minutes | Usually a failed blower motor or blower wheel |
| On steady | Control failure | Cycle the power; if it comes back, a new board (it isn’t field-repairable) |

This furnace has three pressure switches, watching the combustion air, the vent piping and the condensate drain.
| Flashes | What it means | What it usually takes |
|---|---|---|
| Continuous amber | Flame signal below 1.5 microamps | Clean the flame sensor and check the gas flow |
| 3 red | Pressure switch open when it should be closed | The inducer, a blocked vent, a pressure switch hose or the drain |
| 4 red | Main limit switch open | A dirty filter, the ductwork or the blower speed |
| 5 red | Limit circuit open over 15 minutes, usually a hand-reset rollout switch | Call: combustion air, the inducer, the burners or the heat exchanger |
| 7 red | No flame after three tries; one-hour lockout | Gas supply, igniter, gas valve or flame sensor |
| 8 red | Flame lost five times in one call for heat | Gas pressure, the flame sensor or the gas valve |
| 9 red | Reversed polarity, a grounding problem or reversed transformer wires | A wiring fix |
| 11 red | Limit open 5 to 15 minutes | Usually the blower motor or the blower wheel |
| 12 red | Loose or missing model ID plug | Reseat or replace the plug on the board |
| 13 red | High-fire pressure switch open | A partly blocked vent or a loose wire, before the switch |

What it costs
Our own repair prices, the same on a York as on anything else. Tap a system to narrow the list.
Flame sensor cleaned
The thin rod that proves the burners lit. Coated in soot, it tells the board the flame went out, and the gas shuts off a few seconds after the burners light.
$95 to $180
Condensate drain cleared, trap and switch added
High-efficiency furnaces and every AC coil make water. When the drain or trap clogs, a float switch stops the system on purpose so the water doesn’t end up in the ceiling.
$175 to $420
Refrigerant topped up
One to three pounds. If it needs it again next season it’s leaking, and topping it up every year is the expensive way to lose.
$190 to $740
Run capacitor replaced
The part that kicks the compressor and fan motors into turning. The single most common reason an outdoor unit hums and never starts.
$240 to $370
Igniter or flame sensor replaced
A cracked hot surface igniter glows weakly or not at all, so the burners never light. Usually on the van.
$240 to $410
Contactor replaced
The relay that sends power to the outdoor unit. Burnt or stuck points mean it sits silent while the thermostat calls, or runs when it shouldn’t.
$290 to $425
Blower wheel pulled and cleaned
A wheel caked in dust moves a fraction of the air it should: weak airflow, a frozen coil, a furnace tripping its limit.
$300 to $440
Thermostat replaced
Standard through smart, wired and set up for the system it runs.
$300 to $640
Defrost board replaced
Heat pumps only: the board that decides when to melt the ice off the outdoor coil.
$450 to $1,150
Control board replaced
The brain in the furnace or air handler. When it goes, nothing downstream of it does what it’s told.
$550 to $1,180
Blower motor replaced
The indoor fan motor. The spread is a standard motor against a variable-speed one.
$670 to $2,400
Condenser fan motor replaced
The fan on top of the outdoor unit. If it stops while the compressor runs, the repair gets more expensive by the minute.
$1,100 to $1,500
Refrigerant leak found and repaired
Finding it, fixing it, then recharging the system.
$1,850 to $2,700
or $31/mo at 0% APR for 60 months
Compressor replaced, part under warranty
Labor and refrigerant, when the manufacturer still covers the compressor.
$1,900 to $2,500
or $32/mo at 0% APR for 60 months
Compressor replaced, out of warranty
The big one, and usually the point where replacing the system wins. You get both numbers.
$2,200 to $5,100
or $37/mo at 0% APR for 60 months
Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works
York parts come only through Source 1 Parts, York’s own parts channel, sold through distributors to contractors rather than homeowners (York). Comfort+ members get the $99 diagnostic included in the visit, 15% off any service, and 50% of each repair bill banked toward replacing that system, up to $1,500. How Comfort+ works.
Fix it or replace it
The serial number on the rating plate gives the year it was built. Here’s how to read it.
York doesn’t publish its serial key. Two independent HVAC age guides agree on it, so read it as a good guide rather than York’s word (PickHVAC, Building Intelligence Center). On York, Coleman and Luxaire units built since late 2004, the serial is a letter, a digit, a letter, then seven digits: the 2nd and 4th characters together are the year and the 3rd is the month, A for January through N for December, skipping I and J. N0D6653823 was built in April 2006.
Older serials start with four letters, the 2nd the month and the 3rd the year. A 2001 CPSC recall of furnaces built from May to July 2001 listed serials starting WFKM and WGKM, which fits: F is June, G July, K 2001.
Consumer Reports members expect a gas furnace to last a median of 20 years and central air about 15 (gas furnaces, 2024; central air, 2025). What shortens that: how long a furnace lasts.
Gas furnace alone
$4,285 to $14,040
or $71/mo at 0% APR for 60 months
Keeping the AC you have. By size and efficiency, installed.
Furnace and AC together
$8,898 to $23,000
or $148/mo at 0% APR for 60 months
2 to 5 ton, matched, installed with the permit.
Heat pump system
$8,499 to $21,650
or $142/mo at 0% APR for 60 months
Heat pump and air handler, 2 to 5 ton, installed.
Monthly figures: 60mo @ 0% APR on each starting price, the whole price financed, on approved credit. Longer plans lower the payment and cost more in total. The lender sets the final terms. How financing works

Why we recommend Trane
We fix York the same as anything else, and when one is done, here’s why we’d put in a Trane.

The system we put in first
Built to take a beating. Put in by our crew.
Heat lamps, snow and rain on one outdoor unit: that’s Trane’s own film. We’re a Trane Comfort Specialist, on Trane’s own dealer locator, and when you pick a Trane, our crew puts it in.

The warranty
Maybe, if you’re the one who bought it. Here’s how York’s warranty works.
York’s own terms: York’s warranty page. A manufacturer’s warranty pays for the part, not the labor; we look up your serial number before ordering anything.
Where we work
Out of Chantilly and Ashburn, across six counties from Fairfax to Stafford. Pick your town for its own furnace repair page: the houses there, the county’s permit rules, and the same prices.

Asked on the phone
The diagnostic is $99. Most York repairs run $95 to $1,500: a flame sensor cleaned is $95 to $180, an igniter $240 to $410, a capacitor $240 to $370, a control board $550 to $1,180. If it’s past fixing, a new Trane furnace is $4,285 to $14,040 installed and a furnace with an AC is $8,898 to $23,000. From about $71 a month at 0% APR for 60 months, the whole price financed, on approved credit. How financing works
Count them through the window in the blower door. On most York furnaces, 3 red flashes means the pressure switch never closed (the inducer, a blocked vent or a hose), 4 means the high limit opened (often a dirty filter or poor airflow), 7 means it failed to light three times, and 11 means the blower likely failed. A light that stays on means the board failed, and York’s boards aren’t field-repairable. Both tables are on this page.
Bosch. York’s home heating and cooling business has belonged to Bosch since July 31, 2025, and Johnson Controls still owns the York name and licenses it. Coleman HVAC and Luxaire are Bosch Home Comfort’s regional brands from the same family: a 2001 recall covered York-built furnaces sold under all three names.
York builds a full line, from entry models to the Affinity series. In Consumer Reports’ 2022 central air survey, York, Coleman and Luxaire got a Fair reliability rating (no brand got Poor), and CR found their evaporator coils had a 10 percent problem rate against a 5 percent average. A York in good shape is worth fixing. When one is done, we’d put in a Trane, the only brand in that survey rated Excellent for both reliability and owner satisfaction.
Yes. A York furnace lights, proves its flame and moves air the same way any furnace does, and its codes are printed in York’s own manuals. York parts come only through Source 1 Parts, sold through distributors to contractors, so a York repair goes through a contractor either way.
Not according to York’s 2024 warranty booklets: the warranty covers only the original buyer and doesn’t transfer to the next homeowner. We’ll still look up the serial number, and the repair price is the same either way.
