AfterHVAC Company in San Antonio, TX
Dalton Heating & Air is the HVAC company San Antonio homeowners call when the air conditioner quits in August or the furnace won’t fire on a January morning. This city’s heat and humidity punish equipment, and the older housing stock across the north side means a lot of systems are past their prime. We run every San Antonio job on The Garrison Standard: a written price before any work starts, a technician who arrives inside the window, and a full-year written guarantee on every repair. Call (361) 306-9515 and a live person answers, day or night.
Why San Antonio Homes Are Different
San Antonio air conditioners run harder than systems almost anywhere else in Texas. Summer highs above 100°F are normal from June through September, and the humidity off the Gulf means the compressor and condenser coil get no easy days. We see capacitor failures and contactor burnouts in Alamo Heights and Stone Oak at the same rate as in older neighborhoods like Jefferson and Woodlawn Lake, because the load is constant everywhere.
The housing stock splits three ways. The 1950s and 60s ranches inside Loop 410 and across the northeast side often still run on original duct sizing that was never designed for modern high-efficiency equipment. The big 1990s and 2000s subdivisions around Bandera Road and Culebra Road have systems hitting the 15-20 year mark, which is when heat exchangers and evaporator coils start failing. And the new builds along Potranco Road and outside Loop 1604 have high-efficiency equipment that still needs annual maintenance to hold its warranty. Add caliche soil that settles and shifts outdoor condenser pads, and a San Antonio HVAC job is never quite the same as the next city over.
Our Main San Antonio Services
Most calls to Dalton Heating & Air in San Antonio fall into two camps: an air conditioner that stopped cooling, and a heating system that needs to be replaced or repaired. All three services below have their own San Antonio page with pricing, timelines, and specifics.
AC Repair in San Antonio
When a San Antonio air conditioner breaks in July, waiting two days for a diagnostic isn’t workable. Our AC repair crews in San Antonio carry capacitors, contactors, and fan motors on the truck so most calls are completed the same visit. Refrigerant leaks are common in this market because high heat and humidity accelerate corrosion at braze joints and evaporator coils. The full scope of San Antonio AC repair work, including the written price promise and the 365-Day Done Right Promise, is on the dedicated page.
Heat Pump Installation in San Antonio
Heat pumps make real sense for San Antonio’s mild winters and long shoulder seasons, especially in homes without natural gas or in additions where running a gas line is impractical. The installation itself involves an outdoor unit, an air handler, a line set, and either duct adaptation or new ductwork where needed. San Antonio’s hard soil and small lot clearances often dictate where the condenser can sit. For a written fixed price, rebate handling, and a schedule that isn’t a moving target, see the full page.

Furnace Repair in San Antonio
San Antonio furnaces get a short but real workout from December through February, and most failures show up on the first cold snap of the year. Common issues here include failed ignitors, dirty flame sensors, and cracked heat exchangers in furnaces that haven’t been inspected in years. A furnace that won’t light is also a carbon monoxide concern, so we treat no-heat calls in San Antonio as a priority. The dedicated furnace repair page for San Antonio covers the diagnosis process and what a repair typically costs.

FAQs About HVAC Company in San Antonio
Most calls inside San Antonio can be scheduled same day or next morning. In a no-cool situation during a heat wave or a no-heat call in freezing weather, we put San Antonio jobs at the front of the line. A real person takes the call at any hour, and the technician arrives inside the stated window.
San Antonio requires permits for installations that involve equipment changes or ductwork, and we handle that paperwork as part of the job. Repairs and part replacements generally don’t need a permit. If a permit is required, it’s included in the written quote before any work starts.
Some San Antonio HOAs, especially in newer subdivisions around Stone Oak and Alamo Ranch, have rules about condenser placement, screening, and noise. We’re familiar with those requirements and factor them into the job before installation day so you don’t end up in a dispute after the work is done.
