Commercial HVAC Services
Rooftop units, split systems, and ventilation for Katy offices, retail, and restaurants — serviced by techs who understand that downtime costs you money. Planned maintenance agreements keep your equipment running and your tenants comfortable.

Blowing warm air, short-cycling, strange noises, or no cooling at all — our Katy AC repair techs diagnose the real cause and fix it fast, before a small issue fries your compressor. Most common repairs finish in a single visit.
Zoning Systems
Upstairs too hot, downstairs too cold? Zoning divides your Katy home into independently controlled areas with motorized dampers and multiple thermostats — comfort where you want it, savings where you do not.
Thermostat Installation & Repair
A smart thermostat only saves money if it is wired and configured correctly for your equipment. Our Katy techs install and program thermostats to match your furnace, AC, or heat pump — and show you how to use the schedules.
Duct Cleaning
