Fast, Reliable Furnace Repair Across Selma
Most furnace repairs in Selma run $150 – $700, and a no-heat call is usually something we can diagnose the same day. If your furnace is blowing cold air, short cycling, or making a sound it shouldn’t, you want a tech who shows up inside the window and puts the price in writing before touching anything. That’s how we work at Dalton Heating & Air. Our crews know Selma’s neighborhoods, from the newer builds east of I-35 to the established streets around Retama Springs. Call (361) 306-9515 for a free estimate, and you’ll talk to a live person, not a voicemail tree.
Why Dalton Heating & Air Is Selma’s Preferred Furnace Repair Company
Selma homeowners call us for one reason: they’re done with crews that don’t show up or change the price at the door. Every call we run in Selma follows The Garrison Standard, which means the price goes in writing before any work starts, not after. That’s been our operating rule since 2003, and it applies to every job, from a $150 ignitor swap to a $700 blower motor replacement. No exceptions, no handshake estimates.
What does that look like on a Selma call? A background-checked, uniformed technician arrives in a marked van, explains what’s wrong in plain English, and gives you a written quote. If you approve, the repair is guaranteed in writing for a full year under our 365-Day Done Right Promise. If the work fails in that time, we return at no charge. That’s not an upgrade you buy. It’s included on every service call.
Our techs are factory-trained to service nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Selma specifically, that matters because the local housing mix includes plenty of Goodman and Rheem equipment, plus a growing number of Daikin units in the newer subdivisions around Olympia Hills. We don’t have to guess at those systems.
Furnace Tune Up in Selma
A Furnace Tune Up in Selma runs $80 – $200 and usually takes about an hour. It’s the single best thing a homeowner in this area can do before winter, because Selma’s winter-adjacent season is short and mild, which means furnaces sit idle for long stretches and collect dust, pollen, and combustion residue. When the first real cold front hits in late November or December, that grit is exactly what causes failed ignition and flame sensor faults.
What the Tune-Up Covers
We pull and clean the flame sensor, inspect the heat exchanger for cracks or corrosion, check gas pressure, test the ignitor, and measure the blower motor’s amp draw. Then we do a static pressure check, which tells us whether airflow is within the manufacturer’s spec. That’s a diagnostic most companies skip, and it matters in Selma because oversized equipment in older homes tends to run with restricted airflow, which stresses the whole system.
Written Report, No Sales Pitch
You get a written report showing what we found, what we measured, and what we recommend, if anything. Our techs are not paid on what they sell, so there’s no incentive to invent a repair. If the furnace is healthy, we tell you that. If something is wearing, we show you the measurement and quote you a price only if you want the work done.
Emergency Furnace Repair in Selma
Emergency Furnace Repair in Selma is available 24/7, and when your heat is out on a January night with lows near 38°F, you don’t wait until business hours. Call (361) 306-9515 and a live person answers. We dispatch to Selma quickly, and the repair cost still falls in the standard $150 – $700 range. There’s no overnight surcharge, no “emergency fee” tacked on because the call came in at midnight.
What Counts as an Emergency
No heat, a burning smell, a carbon monoxide alarm going off, or a furnace that won’t stop running are all emergencies. A rattling sound that’s been there for three days is important, but it can usually wait until morning. A furnace that’s tripping the breaker repeatedly or blowing cold air when the thermostat calls for heat should be treated as urgent, especially if anyone in the home is elderly, pregnant, or has a respiratory condition.
Faster Diagnosis, No Guessing
Because our techs carry common Selma-area parts on the truck, including flame sensors, ignitors, capacitors, and vent pressure switches, most emergency calls end with a working furnace on the first visit. We don’t do the thing where a tech shows up, diagnoses the problem, and then says the part is three days out. For the brands we service, we stock the high-failure items.
Trusted Brands We Service in Selma
Selma’s housing stock spans two decades of construction, and the furnaces reflect that. We work on Goodman and Rheem systems every week, from the reliable builders-grade units in the older neighborhoods to the higher-efficiency York and Daikin furnaces in newer developments. Because we carry local parts inventory and route our techs through Selma’s main corridors daily, we can usually get a part in hand the same day it’s diagnosed. If your furnace is an American Standard or a Bryant, we service those too, plus the rest of the nine brands we’re factory-trained on. No matter what’s in your mechanical closet, the diagnostic fee is the same and the written warranty applies.
Common Furnace Repair Problems We See in Selma Homes
- Dust-caked flame sensors. Selma sits in a corridor where surrounding farmland and the constant construction churn put fine dust and pollen into the air. That dust coats the flame sensor and causes intermittent heat or a furnace that won’t stay lit. Cleaning or replacing the sensor usually fixes it in under an hour.
- Weak capacitors after hard summers. Air conditioners work hard in Selma from May through September, and that voltage strain weakens capacitors. When winter comes and the blower motor is asked to run, the tired capacitor struggles, causing hard-starting or a furnace that hums but won’t move air.
- Short cycling from oversized equipment. Homes built in Selma before 2010 commonly have furnaces that are too big for the square footage. The unit reaches temperature fast, shuts off, and kicks back on minutes later. That stresses the heat exchanger and wastes gas. Our load calculation catches this and tells you if the equipment is the problem, not the thermostat.
- Ignitor failure on cooler nights. The ignitor is a common wear item, and Selma’s occasional cold snaps are often the first time the furnace has run in months. If the ignitor has hairline cracks from age, that first cold night is when it quits. We replace them regularly, and the repair is one of the lower-cost items on the Furnace Repair list.

FAQs About Furnace Repair in Selma
As a rule, if your furnace is under 12 years old and the repair is under $500, repair it. If the repair involves a cracked heat exchanger or the unit is over 15 years old with a history of failures, replacement is usually the smarter money. In Selma, that math shifts slightly because our winters are mild, which means furnaces see less annual runtime than systems up north. That lower runtime often extends the useful life of a furnace here, so a 15-year-old Selma furnace with a clean heat exchanger and solid blower motor still has life in it. Our techs will give you a straight answer, not a replacement pitch. Call (361) 306-9515 for a diagnostic, and we’ll walk you through the numbers.
Most furnace repairs in Selma run $150 to $700, with the majority falling between $200 and $400. Small fixes like a flame sensor cleaning or ignitor replacement sit at the low end. Gas valves and blower motors land in the middle. A heat exchanger, the most expensive component to replace, pushes toward the top of the range. You’ll get an exact written price before any work begins, not after. Free estimates, no obligation to proceed.
Short cycling in Selma usually comes down to one of two things: an oversized furnace or a dirty flame sensor. The oversized unit hits temperature quickly, shuts off, and restarts minutes later, stressing the heat exchanger. Homes built in Selma before 2010 are especially prone to this. A dirty flame sensor causes a different pattern: the furnace fires, the sensor reads the flame incorrectly, and the system shuts down as a safety measure, then tries again. Our diagnostic includes a load calculation and a static pressure check to tell you which one you’re dealing with.
Once a year, ideally in October or November before the first real cold snap. Selma’s air carries a lot of dust and pollen, more than you’ll find in cleaner coastal climates, and that material settles on the flame sensor and blower motor during the months the furnace sits idle. A $80 – $200 tune-up catches the small stuff before it becomes a cold-night breakdown. If you skipped last year, book one now.
We service all nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. In Selma specifically, we see a lot of Goodman and Rheem in the older neighborhoods and a growing number of York and Daikin units in the newer subdivisions. Our techs are factory-trained on each brand, which means we repair to the manufacturer’s spec, not a workaround.
One Thing Every Selma Homeowner Should Know
Selma’s Central Valley climate swing, January lows near 38°F and July highs near 98°F, means your furnace is really one half of a year-round system. We don’t diagnose a furnace in isolation. On every no-heat call in Selma, our diagnostic includes a load calculation and a static pressure check, because the same ductwork and blower that move heat in January move cooling in August. If the static pressure is off, your furnace is working against restrictions that will eventually shorten its life and raise your gas bill. That’s the kind of finding you only get from a company that treats the whole system, not just the part that’s currently broken.
