Services available in 78245
- Thermostat Installation & Repair — A smart thermostat only saves money if it is wired and configured correctly for your equipment. Our San Antonio techs install and program thermostats to match your furnace, AC, or heat pump — and show you how to use the schedules.
- Duct Cleaning — Leaky, dirty ducts can waste 20–30% of your heating and cooling. Our San Antonio duct cleaning crews clean supply and return runs, then flag leaks and insulation gaps worth fixing — because clean ducts attached to leaky ones only go so far.
- AC Installation & Replacement — A new AC is a 12–15 year decision. Our San Antonio installation crews size by Manual J calculation, not rule of thumb, and set up airflow and charge correctly — the details that separate a system that lasts from one that limps.
- Indoor Air Quality Solutions — Wildfire smoke season turned indoor air quality from a luxury into a necessity in San Antonio. We install whole-home filtration and air-cleaning add-ons that work with your existing furnace or air handler — not against it. Breathe easier: (877) 317-0473.
