AfterAmeristar Construction in San Antonio, CA | Rowan Construction Group
Rowan Construction Group provides independent Ameristar sales & service across San Antonio, from the Edwards limestone shelf on the north side to the expansive Vertisol clay in the south. We’re not manufacturer-affiliated or authorized by Ameristar, which means we answer to you, not to a corporate warranty desk. What makes our Ameristar work different here is simple: we’ve spent over a decade trenching, pouring, and roofing around these systems on both sides of the Balcones Escarpment, and we know which side of town changes the job before we even show up. Call (470) 298-9650 for a written quote before any work starts.
Why San Antonio Residents Choose Us for Ameristar Service
The Ameristar units scattered across San Antonio’s housing stock aren’t all the same age, same condition, or same installation quality. We’ve pulled 13 SEER R410A condensers off 1990s brick-veneer slabs in the northeast, serviced 14 SEER heat pumps in Stone Oak production homes, and diagnosed variable-speed air handlers in westside pier-and-beam bungalows where the ductwork runs through a crawlspace that hasn’t been dry since the last flash flood. That range of field time matters.
Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College, where he learned framing, concrete, and estimating before he ever ran a paying job. He tends to say the same thing on every walk-through: measure twice, say it once, show your work. We bring that to every Ameristar service in Austin and San Antonio, which means you get a written price before we touch anything, a documented photo record when we leave, and a straight answer about whether a repair beats a replacement.
We stock genuine Ameristar OEM components for current R410A models and name-brand aftermarket coils and capacitors for the discontinued 13 SEER lines. No waiting on a slow distributor run from Dallas when your condenser quits in August.
Common Ameristar Construction Problems We Solve in San Antonio
- Evaporator coil leaks on older R410A units. San Antonio’s hard water leaves mineral scale on coils, and scale accelerates pin-hole corrosion. We see this most often on 2000s-era tract homes where the original coil was marginal to begin with. We pressure-test, pinpoint the leak, and replace with an OEM coil when available, or a spec-matched aftermarket coil when the original line is discontinued.
- Condenser fan motor failures during 100°F+ heat runs. Limestone dust from nearby construction on the north and northwest side gets into bearing seals and kills condenser fan motors faster than the spec sheet suggests. When consecutive triple-digit days hit, that dust bakes into the housing. We carry replacement motors for the most common Ameristar condenser frames so the fix doesn’t wait on a parts truck.
- Compressor contactor pitting and welding. Voltage sags during peak A/C load, especially in older post-tension slab neighborhoods with aging distribution lines, cause contactor arcing. Burned contacts weld shut or pit until the compressor won’t start. We replace the contactor, check the capacitor, and test line voltage at the disconnect before we call it done.
- Drain pan overflow and secondary shut-off float failures. In pier-and-beam homes on the near southside, high humidity plus occasional flooding saturates duct insulation, and the pan sees more condensate than the original float switch was ever sized for. We install secondary float switches and re-slope pans on service calls where the first warning sign is water staining the closet ceiling.
- Rooftop packaged unit failures after storm-driven debris impact. Ameristar packaged gas/electric rooftop units take direct hits from hail and wind-blown branches in flash-flood alley. We inspect the cabinet, evap coil, and gas heat exchanger after storms, because a cracked heat exchanger is a carbon monoxide risk, not a comfort issue. If the roof itself is compromised, our roofing crew can address both problems in one visit.
BeforeAfterAmeristar Service in San Antonio: What Local Conditions Mean for Your Equipment
Here’s what out-of-town crews miss. San Antonio sits on the Balcones Escarpment, and the ground changes character inside a few blocks. South and east, the soil is deep, highly expansive Vertisol clay that shrinks during drought cycles and pushes upward when rain returns. North and northwest, from Stone Oak through Helotes and up the IH-10 corridor, you hit solid Edwards limestone two to four feet below grade. That’s not a footnote. It means a trench for a condenser lineset or electrical run that takes two hours on the south side can take three days on the north side, because the crew has to cut or break continuous limestone shelf instead of digging clay. The same Ameristar condenser pad set near Helotes needs a different base prep, different drainage plan, and different anchoring than the identical unit set in a near southside yard. We quote for the geology, not the dirt someone assumes is under it.
Ameristar Models & Products We Service in San Antonio
We service the full Ameristar residential and light-commercial range: the 13 SEER R410A split system, the 14 SEER heat pump, the variable-speed air handler, and the packaged gas/electric rooftop unit. For current R410A models, we use genuine Ameristar OEM parts when they’re available. For discontinued 13 SEER lines where OEM coils and capacitors are no longer produced, we source name-brand aftermarket components that meet or exceed the original spec, and we tell you which one you’re getting before we install it. If the compressor or coil fails on a unit that’s ten years or older, we give you a written repair-versus-replace cost comparison before you spend a dollar on parts.

FAQs - Ameristar Construction in San Antonio
Yes. On post-tension slabs, especially in the 1970s-90s brick-veneer neighborhoods across the north and east, the pad and lineset must accommodate long-term slab movement from expansive clay. We use vibration isolators and flexible lineset routing on slab homes. On pier-and-beam homes on the westside and near southside, we anchor the condenser to a stable base off the crawlspace structure and pay extra attention to drain pan pitch, since those homes see higher crawlspace humidity. Call (470) 298-9650 and we’ll tell you which situation matches your house.
Yes, with a caveat. Genuine Ameristar OEM parts are still available for many 13 SEER units, but certain coils and capacitors for the earliest production runs are discontinued. When that happens, we source name-brand aftermarket parts that meet or exceed the original specifications, and we show you the spec sheet before the part goes in. If you’d like a specific parts availability check for your unit, call (470) 298-9650 and we’ll look it up.
Yes. Stone Oak and much of the north and northwest side sit inside the Edwards Aquifer Recharge Zone, where SAWS enforces impervious-cover caps and drainage requirements. A roof replacement that changes runoff patterns can trigger requirements for specialized drainage channels or pervious surfaces. We handle the roof, the drainage compliance, the Ameristar rooftop unit, and any Driveway & Pavers in San Antonio in one scope, so you’re not coordinating three contractors. Call (470) 298-9650 for a written quote that includes the drainage work.
Most likely, the capacitor took a voltage surge or the contactor is partially welded from a lightning-adjacent spike. In San Antonio’s flash-flood alley, storm voltage dips and surges are common, and capacitors fail before breakers trip. We test the capacitor, contactor, and compressor windings on every post-storm diagnostic call. Call (470) 298-9650 and we’ll diagnose it the same day.
It depends on the failure and the unit’s condition. If the compressor has failed on a 12-year-old Ameristar, replacement usually makes more financial sense than a $3,000+ compressor job on a system near the end of its service life. If it’s a capacitor, contactor, or fan motor, repair is generally the better call. We give you a written repair-versus-replace comparison for every 10+ year unit before you decide. Call (470) 298-9650 and we’ll walk you through it with numbers, not opinions.
