AfterFast, Reliable Furnace Repair Across Selma
Furnace repair in Selma, TX typically costs $150-$700, and most calls are completed same day. Our Furnace Repair team dispatches from our San Antonio office and carries the parts to fix Goodman, Rheem, York, and Daikin systems on the first visit.
We’re familiar with Selma’s mix of post-war ranch homes off Floral Avenue, the 1970s subdivisions near the high school, and the newer builds creeping toward the 99, and our Selma AC Repair team brings that same local knowledge to every cooling call. That variety matters because a furnace in a 1962 slab-on-grade with original flex duct fails differently than one in a 2019 heat-pump package. Our technicians know the local housing stock. They also know that when Tule fog rolls in off the valley floor and temperatures hang near freezing for a week straight, a furnace that was “fine last year” suddenly isn’t. Call us at (817) 402-2972. A live person answers, even at 2 a.m.
Why Coldharbour Heating & Air Is Selma’s Preferred Furnace Repair Company
We’ve been the independently owned and operated face of the Kingswell Guarantee since 2003. That means every repair in Selma comes with four written promises: the price before we start, a firm arrival window, a clean job site, and our 365-Day Done Right Promise. If a repair fails within a full year, we come back and correct it at no charge. The guarantee is on paper, not verbal.
Our technicians are background-checked, uniformed, and trained on nine major residential brands. They carry the common failure parts for Selma’s most-installed systems. No waiting on a warehouse in Fresno.
Phones are answered by a live person 24 hours a day, 7 days a week. No voicemail trees. No “call back in the morning” when your furnace quits during a foggy January night.
We know the local failure patterns. Long Tule-fog runtime in older slab homes rusts heat exchangers that have been deteriorating for decades. Vineyard dust from the August harvest clogs filters and coats inducer motors. These aren’t generic problems. They’re Selma problems, and we fix them regularly.
Furnace Tune Up in Selma
Furnace Tune Up in Selma is a full-system inspection and adjustment that catches the wear patterns our valley climate accelerates. We check heat exchanger integrity, combustion analysis, blower amp draw, gas pressure, and safety controls. A tune-up runs $80-$200 and takes about 90 minutes. In Selma, we recommend scheduling before the first Tule fog arrives, typically late October.
What We Inspect on Every Tune-Up
We pull and inspect the heat exchanger with a borescope, test for carbon monoxide leaks, and measure temperature rise across the coil. We also check static pressure. Selma’s older homes with undersized ductwork often run higher than design, which strains the blower motor and cracks heat exchangers over time. Catching it early saves the furnace.
Filter and Airflow Assessment
We measure airflow at each register and compare it to the manufacturer’s spec. In homes near the raisin drying yards, we often find supply grilles choked with fine agricultural dust even when the filter looks clean. We’ll show you the reading and recommend a filter schedule that matches your location.
Emergency Furnace Repair in Selma
Emergency Furnace Repair in Selma means a technician at your door when your system fails during freezing fog or a cold snap that drops valley temperatures into the 20s. We treat no-heat calls as urgent. Our phone is live 24/7, and we prioritize elderly households, homes with infants, and anyone with medical equipment that requires climate control. Emergency repair costs the same $150-$700 range; we do not charge overtime premiums.
What Counts as an Emergency
No heat at all. A furnace that cycles on and off every few minutes but never warms the house. The smell of gas or burning metal. A carbon monoxide detector alarm. Any of these, and we’ll have someone en route. If you smell gas, exit the home and call your utility first, then call us.
How We Handle Night and Weekend Calls
The same technician who’d arrive Tuesday morning arrives Saturday night. Same van, same parts inventory, same written price before work begins. We don’t send a junior tech after hours. Every repair still carries the 365-Day Done Right Promise, written and signed before we leave.
Trusted Brands We Service in Selma
Our technicians are trained to service Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. We stock the most common ignitors, gas valves, blower motors, and control boards for Goodman, Rheem, York, and Daikin systems, the brands we see most often in Selma’s 1980s and 1990s housing stock. That local parts inventory means faster turnaround. You’re not waiting three days for a control board while your family sleeps in jackets.
Common Furnace Repair Problems We See in Selma Homes
- Cracked heat exchangers in older slab homes. Selma’s long Tule-fog winters force furnaces to run continuously for weeks. In 1950s-1990s ranch homes with minimal insulation, that runtime corrodes heat exchangers that were already marginal. We find them during no-heat calls, often with elevated carbon monoxide readings.
- Short-cycling from vineyard dust. Fine particulate from the August and September raisin harvest clogs filters, coats flame sensors, and blocks inducer ports. The furnace overheats, hits the high-limit switch, and shuts down prematurely. We see this pattern most in homes south and east of downtown, closest to the drying yards.
- Blower motor failure from high static pressure. Original duct systems in Selma’s older homes were sized for smaller furnaces. When a modern high-efficiency unit gets installed without duct modification, the blower works harder, draws more amps, and burns out. We test static pressure on every repair and flag it.
- Failed ignitors in original 1970s-1980s systems. Silicon carbide hot-surface ignitors degrade with thermal cycling. Selma’s temperature swings, 105°F in summer to near-freezing fog in winter, stress them further. We carry universal and OEM replacements for most brands.
Pricing for Furnace Repair in Selma, TX
Most furnace repairs in Selma fall between $150 and $700, parts and labor included. A simple ignitor replacement usually runs $150-$280. A blower motor replacement, which requires pulling the assembly and testing amp draw, typically lands at $400-$650. Heat exchanger repair or replacement often pushes toward the top of the range, and in some cases we recommend furnace replacement if the unit is past 15 years and the exchanger has failed.

What moves the needle: accessibility (rooftop units take longer), parts availability (we stock most common items), and whether we discover secondary damage, like a cracked exchanger that also compromised the inducer. We give you a written price before any work begins. That price does not change at the door. Estimates are free. Call (817) 402-2972.

FAQs About Furnace Repair in Selma
Short-cycling in Selma’s mild-but-foggy winters usually means the furnace is overheating and hitting its high-limit safety switch. The cause is often a clogged filter coated with valley dust, a failing blower motor that can’t move enough air, or a heat exchanger so corroded that exhaust gases back up into the cabinet. Tule fog keeps nighttime temperatures low for long stretches, so the furnace runs more hours per day than in drier climates, accelerating wear. We’ll test combustion, measure temperature rise, and check static pressure to isolate the root cause. Call (817) 402-2972 for a free diagnostic.
Every three to four weeks during August and September, and every six to eight weeks the rest of the year. The fine vineyard dust that rises during harvest season loads standard 1-inch pleated filters faster than typical household dust. We’ve pulled filters completely caked after three weeks in homes off the south and east edges of Selma. A loaded filter raises static pressure, strains the blower motor, and can cause the heat exchanger to overheat. Check monthly. Write the date on the filter frame.
Yes. Our technicians carry compact tools and have experience working in tight Selma closets and on low-slope rooftops where original builders tucked package units. We assess the access before quoting any work, and if a full replacement is needed, we’ll discuss whether relocating the unit is practical. Restricted access doesn’t mean restricted service. Call (817) 402-2972 and we’ll walk through your setup.
If the heat exchanger is cracked, replace it. A cracked exchanger in a 50-year-old furnace is not a repairable condition, and continuing to run it risks carbon monoxide exposure. For simpler failures, like a bad gas valve or ignitor, repair can buy a few more seasons, but factor in efficiency: a 1970s furnace was probably 60-70% efficient, while modern units hit 80-98%. We’ll give you honest numbers for both paths, with a written price for the repair and a separate written quote for replacement. No pressure either way.
Yes. The city of Selma requires a mechanical permit for furnace replacement, which includes a post-installation inspection for gas line integrity, venting, and combustion safety. We pull the permit as part of our installation process and schedule the inspection for you. The permit cost is itemized in your written quote, not hidden. If you’re only repairing an existing furnace, no permit is typically required unless we’re modifying gas lines or venting.
