Why Dalton Heating & Air Is Selma’s Preferred AC Repair Company
Selma homeowners call us after they have been burned. Maybe a previous company quoted one number over the phone and another at the door. Maybe a tech showed up late, or not at all. Or a repair failed three weeks later and nobody answered the callback. That is exactly what The Garrison Standard, in place since 2003, is built to prevent.
Every repair we do in Selma includes a written guarantee, not an unwritten promise. If the repair fails within the 365-day window covered by our Done Right Promise, we return at no charge. That is not an upsell or an add-on. It is the default on every service call.
Our Selma customers also know who is walking up the driveway before they arrive. Every technician is background-checked, uniformed, and factory-trained to service nine major residential brands including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. That matters in a city where one house might have a 2022 Goodman and the house next door still runs a 2011 builder-grade Carrier.
We answer the phone. We show up inside the window. And when it comes to AC Repair, we do not guess. We test, diagnose, and give you a real number before turning a single wrench.
AC Maintenance in Selma
AC Maintenance in Selma is not a generic checklist; it is preventive work tailored to what this part of Bexar County throws at outdoor units. A tune-up here runs $80 – $200 and includes washing the condenser coil, checking refrigerant charge, testing capacitors, inspecting duct static pressure, and verifying the system is moving the airflow it should.
Condenser Coil Cleaning and Airflow Check
Well water, irrigation overspray, and cottonwood from newer subdivision landscaping pack Selma condenser coils with mineral scale and plant fiber. We wash the outdoor coil and measure static pressure across the return and supply. If airflow is weak, we say so plainly instead of just topping off refrigerant.
Electrical and Refrigerant Inspection
We test the capacitor, contactor, and compressor wiring under load. Then we check refrigerant charge against the manufacturer spec. A system that is even a few ounces low runs hotter and costs more to operate. We show you the numbers before we recommend anything.
AC Service in Selma
AC Service in Selma means diagnosing the actual fault, repairing it with the right part, and verifying the system runs correctly before we leave. The work itself ranges from $150 – $650, and you will know that number in writing before we begin. No doors, no surcharges added at the end.
Same-Day Diagnosis and Repair
When a family in Selma Farms has no cooling in July, waiting is not a luxury. We carry common capacitors, contactors, fan motors, and thermostats on the truck so the diagnosis usually becomes the repair on the same visit. If we need a part, we tell you the honest lead time and put the price in writing anyway.
Written Guarantee on Every Repair
Each repair we perform in Selma carries our 365-Day Done Right Promise in writing. If the same repair fails within that year, we return and make it right at no charge. That guarantee is not an upgrade option. It is on every invoice.
Trusted Brands We Service in Selma
We service all nine major residential HVAC brands, and we keep common wear parts for Rheem, York, and Bryant stocked for fast turnaround in Selma. If you have a Daikin heat pump or a builder-installed Trane, that is fine too. Our technicians train across brands so the repair follows the manufacturer’s specification, not a shortcut. A capacitor for a Rheem and a capacitor for a Bryant are not always identical, and we fit the right one.
Common AC Repair Problems We See in Selma Homes
- Condenser coil packed with irrigation dust and cottonwood. Newer subdivisions in Selma run sprinklers near outdoor units, and the mineral-rich well water bakes onto the coil. This chokes heat rejection and drives up compressor temps.
- Weak capacitor causing hard starts. A failing capacitor makes the compressor work harder to start, which shortens its life. In Bexar County summers, this failure happens fast. We test the capacitor under load before it strands you.
- Undersized return ducts from builder-grade installs. Fast-growth neighborhoods like Retama Springs have systems where the return static pressure is too high, which freezes the evaporator coil and fools a homeowner into thinking the refrigerant is low.
- Incorrect refrigerant level from a previous recharge. A system overcharged by a guess-and-go tech will flood the compressor. We use manufacturer charge tables, not the outside temperature alone.

FAQs About AC Repair in Selma
If the system has a 14-year-old compressor, R-22 refrigerant, and the repair is $400, the honest answer is usually a load calculation before you spend another dollar on either path. In Selma, many 14-year-old systems are builder-grade units with undersized returns and dirty coils. Replacing the system without a load calc risks installing the same oversized mistake again. A proper Manual J load calculation tells us what tonnage the house actually needs, and then the repair-versus-replace decision becomes math instead of guesswork. Call (361) 306-9515 and Marco Benitez will walk you through the numbers.
Freezing in Selma is rarely just a refrigerant problem. The most common culprit we find in neighborhoods like Retama Springs and Selma Farms is undersized return ducting that creates high static pressure and drops the evaporator coil below freezing. A dirty evaporator coil or a blower running at the wrong speed does the same thing. Recharging the refrigerant without fixing the airflow just hides the problem until the coil freezes again. We measure static pressure and airflow on every call, and show you the readings.
Twice a year is right for Selma’s climate: once in spring before the heat hits hard, and once in early fall if the system runs a full summer of heavy cooling. The irrigation minerals, cottonwood, and dust in this part of Bexar County load up a condenser coil badly in one season. A spring tune-up runs $80 – $200 and catches weak capacitors before they fail on a 100-degree day.
SEER2 is the federal efficiency rating for air conditioners that took effect in 2023, and it measures cooling output per watt more strictly than the old SEER number did. For Selma homeowners, a system jumping from a 10 SEER R-22 unit to a 15 or 16 SEER2 unit cuts cooling energy use roughly 30 to 40 percent. That is not marketing speak; it shows up on the CPS Energy bill. The tradeoff is upfront cost, which is why we run the repair-versus-replace math with actual SEER2 numbers and your home’s load calculation, not a vague promise of savings.
We service all nine major residential HVAC brands: Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. If your Selma home has a less common brand, call (361) 306-9515 and tell us the model. We will tell you honestly if we can get the part same-week, and you will know the price in writing before we order it.
