Halden Heating and Air is the HVAC company in San Antonio, TX built for homeowners who expect a written price before any work starts, a live arrival time they can track, and a real person on the phone at 3 a.m. when the AC dies in August. San Antonio’s housing stock and climate make this work different than almost anywhere else in Texas: long 100°F+ summers, high humidity, aging 1960s-1980s tract homes with undersized ductwork, and a spring allergy season that punishes dirty filtration. Every job we do here comes with the 365-Day Done Right Promise, written on paper. Call (903) 623-6784 any hour to talk to a live person.
Why San Antonio Homes Are Different
San Antonio’s heat is not a comfort issue. It’s a safety issue. When July pushes 102°F with 70% humidity, a failed AC in a 1970s tract home with original insulation becomes an urgent health problem for kids, seniors, and anyone with a heart or lung condition. The housing stock makes it harder: much of the north and west sides were built between 1960 and 1985, when undersized return ducts and minimal attic insulation were standard. That means the evaporator coil (the indoor part that absorbs heat) runs colder and longer than it should, and in high humidity, it ices over. In neighborhoods like Alamo Heights and Olmos Park, many 1920s-1950s homes were built with undersized returns from day one. We see frozen coils there on the hottest afternoons every single summer. Newer subdivisions on the far north and west sides have the opposite problem: modern construction, but builder-grade HVAC systems installed for the lowest bid, often struggling with humidity control because they were sized for a colder climate. Winter freezes add another layer. A hard freeze can crack an unprotected outdoor condenser or burst a water line near a furnace. Our technicians know this city’s homes block by block, and they plan for it.
Styles & brands we work with
Our Main San Antonio Services
Most San Antonio homeowners call us for one of three things: an AC that stopped cooling in the middle of a heat wave, a full system replacement that finally fixes their humidity and energy bills, or a furnace that failed on one of the few genuinely cold nights we get. Each has its own detailed page below.
AC Repair in San Antonio
When a San Antonio AC fails in summer, the clock is running. We keep common parts for Carrier, Trane, and Goodman systems stocked in local vans so most repairs are same-day, not next-week. The most common San Antonio failures we see are refrigerant leaks (coolant loss from vibration and age), failed capacitors (the electrical boost that starts the compressor), and frozen evaporator coils caused by dirty filters or undersized returns. Every repair gets a written price before we touch the unit, and a written guarantee. If the fix fails within the coverage window, the second visit is free. AC Repair in San Antonio
AC Installation in San Antonio
A new AC in San Antonio needs to do two things: move heat out and pull humidity down. That means the sizing calculation (called a load calculation) matters more here than in drier cities, and so does matching the indoor air handler to the outdoor condenser correctly. Many homes we see were originally equipped with systems too big for their ductwork, which cools fast but never dehumidifies, leaving the house clammy at 72°F. A properly sized system with the right coil runs longer, pulls more moisture out, and costs less to operate. AC Installation in San Antonio
Furnace Repair in San Antonio
San Antonio’s winters are mild, but when a cold front drops temperatures into the 20s, a furnace that has sat idle since March often refuses to fire. We see failed igniters, dirty flame sensors (the part that tells the furnace the flame is lit), and cracked heat exchangers in older units. The most common issue after a winter freeze is a furnace short-cycling, which is usually a shutoff switch triggered by a blocked flue or a dirty filter. Because our furnaces only run a few hundred hours a year, repairs are usually simple and fast. Furnace Repair in San Antonio

AfterPricing for HVAC Company in San Antonio, TX
| Service | Typical range in San Antonio |

What pushes a San Antonio repair toward the top of that range is humidity damage: corroded contactor switches and rusted control boards from a decade of damp air, plus the extra heat load that wears out capacitors and compressors faster than in drier parts of the country. Whatever the number, you’ll see it in writing before we pick up a tool. That’s not an offer. It’s the way every job works.

FAQs About HVAC Company in San Antonio
Most San Antonio calls get a same-day visit, and during heat waves we run extended crews specifically because a failed AC in 100°F heat is a life-safety issue, not a scheduling preference. When you book online, you get a live arrival time you can track to the door. Every repair includes a written guarantee.
Most HVAC replacements in San Antonio require a permit, which is pulled by the installing contractor, not the homeowner. We handle all permit paperwork as part of the installation. Repairs and tune-ups typically do not require a permit. If your HOA has architectural rules about outdoor unit placement, we’ll check before installation day.
High humidity is the biggest factor. It corrodes electrical components, stresses compressors, and means every system has to work harder through longer summers. Aging 1960s-1980s ductwork on the north and west sides also means installations often include duct sealing or replacement that a newer home would not need. Call (903) 623-6784 for an exact quote.
