Licensed HVAC Contractor in San Antonio
AC repair and HVAC service in San Antonio from a licensed veteran-owned contractor: no-cool diagnostics, replacements, ductwork, and maintenance.
C.S.W. Power Solutions is a licensed HVAC contractor in San Antonio operating under Texas Air Conditioning and Refrigeration license TACLA26479R. We diagnose, repair, and replace residential and light-commercial cooling and heating systems built for South Texas summers and short cold snaps. Because electrical (TECL31793) is held in-house under the same general contractor, HVAC sizing, panel capacity, and generator readiness can be planned together. CSW provides San Antonio AC repair and HVAC service — no-cool diagnostics, AC replacement, ductwork, mini-splits, and thermostats — for homes and light-commercial properties across San Antonio, Castle Hills, and Boerne. HVAC is one of the licensed trades held in-house under CSW's veteran-owned general contractor umbrella.
AC Repair and No-Cool Diagnostics
Weak airflow, warm air at the registers, short cycling, frozen coils, blocked condensate drains, electrical faults, thermostat issues, and refrigerant problems are all diagnosed before any repair recommendation is written. We document what we measured — supply and return temperature split, static pressure, capacitor reading, breaker condition — so the homeowner sees why the recommendation is what it is.
Complete AC Changeouts and System Replacement
When repair is no longer the right call, complete changeouts cover sizing (Manual J informed by Texas summer load, attic geometry, and clay-soil foundation effects), line-set inspection or replacement, electrical disconnect, thermostat, permit, startup, and inspection. Goodman, RunTru, Payne, Oxbox, and other supported brands; 14.3–15.2 SEER2 baseline with premium options available.
Ductwork, Mini-Splits, and Thermostats
Ductwork inspection, leak sealing, undersized run replacement, and full duct retrofits for older San Antonio homes. Single-zone and multi-zone ductless mini-splits for garages, additions, sunrooms, and historic homes without ducts. Smart thermostat installation (Nest, Ecobee, Honeywell) with proper C-wire and multi-zone configuration.
HVAC and Generator Load Planning Together
Because electrical is held in-house, generator load planning and HVAC sizing can be coordinated — air handler, condenser, and electric strip heat can be wired through a transfer switch where standby capacity supports it. Whole-home and essential-load configurations are reviewed against panel capacity and gas supply.
