Furnace repair in Carrollton typically runs $150 – $700, with most jobs completed the same day by a technician who knows this city’s homes well. Whether your furnace quit on the first cold morning off Josey Lane or you’re hearing a rattle from an aging blower motor in a 1980s slab home near Hebron Parkway, we can get it diagnosed and fixed. Call (430) 213-5796 for a free estimate and a straight answer about what’s wrong and what it costs.
Carrollton’s split between Dallas and Denton counties means furnace repair isn’t just about the mechanical fix. The permit on one side of the street isn’t always the same on the other. We carry both county code books. The technician who shows up knows which forms to pull before touching a gas valve or heat exchanger. That kind of local detail matters when you need heat back on and you don’t have time to wait three days for paperwork.
Why Cold Harbour Heating and Air Dallas Is Carrollton’s Preferred Furnace Repair Company
Carrollton homeowners have called us since 2003 for one simple reason: we write down our promises before the work starts. Every repair gets a written price handed to you before a tool comes out. Every repair also gets the 365-Day Done Right Promise in writing. If a repair fails within a full year, we come back and correct it at no charge. Not “may we suggest.” No argument. It’s on paper.

They’re uniformed, background-checked, and they won’t leave your crawlspace or attic messier than they found it. The five values of Furnace Repair at Coldharbour are the same every time: say the price, show up in the window, leave it clean, put the guarantee in writing, and come back if it fails.
We dispatch to Carrollton from our Dallas-Fort Worth metro office, and a live person answers our phones 24 hours a day, 7 days a week. No voicemail trees, no “leave a message and we’ll call you tomorrow.” When your furnace won’t light on a 35-degree February night, you talk to a human who can get a truck rolling.
Styles & brands we work with






Furnace Tune Up in Carrollton
A Furnace Tune Up in Carrollton runs $80 – $200 and is the cheapest way to avoid a middle-of-January repair call. We inspect the heat exchanger for cracks, test the ignitor and flame sensor, check gas pressure, clean the burners, and measure the temperature rise across the system. The written report you get afterward tells you exactly what we found, with photos on request. Our technicians are not paid on what they sell, so we won’t invent a repair to pad the invoice.
What a Tune-Up Catches Before It Fails
On older Carrollton furnaces, the most common finding is a dirty flame sensor shutting the system down randomly. Second is a heat exchanger with hairline cracks that would only show up under a camera inspection. We catch these things in October and November, before they become emergency calls in January.
When Carrollton Homes Need It Most
The shoulder seasons here are the real test. Carrollton’s dramatic temperature swings in November and March make furnaces cycle more often than they would in a consistently cold climate. More cycles means more strain on capacitors, ignitors, and blower motors. A tune-up before Thanksgiving is cheap insurance.
Emergency Furnace Repair in Carrollton
Emergency Furnace Repair in Carrollton costs $150 – $700 depending on what failed, and we answer the phone at 3 a.m. because a cold house in winter is a health risk, not an inconvenience. The most common emergency calls we get in Carrollton are furnaces that won’t fire at all, blower motors that hum but won’t turn, and heat exchangers tripping the rollout switch. Our techs carry a truck stock of ignitors, flame sensors, capacitors, gas valves, and blower motors, so most emergency repairs are finished in one visit.
No Overtime Charge on Nights and Weekends
If your furnace dies on a Saturday night in December, you pay the same labor rate as a Tuesday morning call. The price is written before we start. The 365-Day Done Right Promise applies to emergency work the same as any other repair.
What We Check First on an Emergency Call
Sequence of operation. That’s the trade way of saying we confirm the thermostat is calling for heat, the inducer motor is running, the ignitor is glowing or sparking, the gas valve opens, the burners light, and the blower kicks on. In Carrollton’s older homes, the culprit is often a weak ignitor or a gas valve that’s slow to open. We diagnose it in minutes, not hours.
Trusted Brands We Service in Carrollton
We service and repair furnaces from Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. When a Carrollton homeowner off Marsh Lane needs a Trane gas valve or a Carrier ignitor, we often have the part on the truck. If not, we source it locally the same day. You won’t wait a week for a part that should have been stocked in the metro.

AfterCommon Furnace Repair Problems We See in Carrollton Homes
- Short-cycling from clogged condensate drains. Carrollton’s shoulder-season humidity and temperature swings cause condensate drain lines to back up, tripping safety switches and cycling the furnace on and off. We clear the line, test the switch, and the system settles down.
- Static pressure spikes from corroded 1980s ductwork. Original round metal ducts in older slab homes near Josey Lane and Hebron Parkway rust from decades of attic heat. A collapsed duct section chokes airflow and makes the furnace cycle erratically.
- Weak ignitors and flame sensors in high-use systems. Mild winters mean Carrollton furnaces aren’t always maintained annually. The ignitor gets brittle, the flame sensor gets coated, and the furnace won’t light on the first genuinely cold morning.
- Stress on blower motors from aging R-22 heat pump systems. Clay-heavy soil shifting under slab foundations pulls on refrigerant lines and duct connections, creating slow leaks that force the blower to work harder. We see the result in failed capacitors and overheated motors.

FAQs About Furnace Repair in Carrollton
Yes, and that’s a real Carrollton quirk. Carrollton spans two counties, so the permitting rules for a gas valve or heat exchanger repair depend on which side of the county line your home falls on, even within the same neighborhood off Josey Lane. We know the forms and the inspection process for both Denton and Dallas counties, so the permit doesn’t delay your heat. Call (430) 213-5796 and we’ll tell you exactly what your address requires.
In Carrollton’s older slab homes, the most likely culprits are a backed-up condensate drain, a failing flame sensor, or undersized ductwork that’s choking airflow. The temperature swings make the system cycle more often, which exposes weaknesses faster. We diagnose the sequence of operation on site and tell you the true cause before we touch a part. A tune-up is $80 – $200.
Sometimes a section patch is enough, but the decision depends on how far the corrosion has spread through the trunk line. On a 1980s slab home near Hebron Parkway, we found a collapsed duct section killing airflow to back bedrooms and driving static pressure above 0.9″ WC. We patched the corroded run, cleared the condensate drain, and the furnace stopped short-cycling. We’ll inspect the whole trunk and tell you honestly whether a patch holds or the whole run needs replacement.
No. If the furnace itself is repairable, we fix it and leave the heat pump alone. You’re not forced into a full system replacement just because the R-22 refrigerant is old. But if the furnace failure is tied to the blower or coil and the R-22 system is already leaking, we’ll show you the numbers for both options and let you decide. The repair price is written before work starts, and the choice stays yours.
That’s usually the evaporator coil freezing because of low airflow or a refrigerant issue crossing over from the cooling side. In Carrollton’s clay-heavy soil, slab settling can pull on refrigerant lines and create slow leaks that starve the coil. The system freezes even in mild weather. We check the charge, the duct static, and the drain line before recommending anything. Call (430) 213-5796 for an exact quote.
