AC Installation in Katy, TX
Texas TDLR Licensed Air Conditioning & Refrigeration Contractor (#TACLB145586E) installing and replacing central air conditioning systems for Katy homes. Proper Manual J sizing, equipment selected for west Houston humidity, and full City of Katy permitting so your new system delivers reliable cooling and better dehumidification from day one.
AC Installation Built for Katy Homes and Climate
Katy homes — whether in established neighborhoods like Cinco Ranch or newer communities such as Elyson, Cane Island, Firethorne, and Seven Meadows — face long cooling seasons and high outdoor humidity. An oversized system that short-cycles leaves rooms cool but clammy. An undersized system runs constantly and still struggles in August. We size every residential AC installation with a proper load calculation and select equipment that removes both heat and moisture effectively.

How Residential AC Installation Works in Katy
A clear process from the first home assessment through City of Katy inspection and system handover.
In-Home Assessment
We visit your Katy home, evaluate the existing system and ductwork, note attic and electrical conditions, and discuss comfort goals, budget, and any humidity or hot-room issues you have been living with.
Load Calculation & Equipment Recommendation
A Manual J-style load calculation is completed for your specific home. We then recommend system capacity, efficiency level, and features (single-stage, two-stage, or variable-speed) that match how you actually use the house.
Permitting & Scheduling
We submit the City of Katy mechanical / HVAC permit. Once equipment is ordered and the permit is in process, we schedule the installation on a date that works for your household.
Professional Installation
Licensed technicians remove the old equipment, set the new outdoor and indoor units, make refrigerant and electrical connections, address any necessary duct transitions, and commission the system. The work area is left clean.
Final Inspection & Walkthrough
We meet the City of Katy inspection and then walk you through thermostat operation, filter locations, and recommended maintenance so you get the full benefit of the new system.
Because we are based in nearby Cypress, most Katy residential installations can be scheduled promptly and completed with minimal disruption to your routine.

Katy AC Installation FAQ
Most central air conditioning replacements are completed in one day once the equipment is on site. More complex projects (significant duct modifications, electrical upgrades, or difficult access) may require a second day. We provide a clear schedule after the in-home assessment.
Yes. Every residential AC installation begins with a proper load calculation so the system is sized for your specific home and Katy climate conditions rather than a generic rule of thumb.
Yes. We submit the required mechanical / HVAC permit and coordinate the inspection as part of the installation.
High outdoor humidity means the system must run long enough to remove moisture. An oversized unit cools the air quickly and shuts off before it has dehumidified the space, leaving the home feeling clammy. Correct sizing is the foundation of comfort here.
We recommend equipment that balances upfront cost with long-term operating cost and humidity performance. Two-stage and variable-speed systems often provide the best comfort in Katy’s climate because they run longer, quieter cycles that remove more moisture.
Yes. We schedule installations on weekdays and, when capacity allows, on Saturdays so the work fits your household’s routine.
Yes. We provide residential maintenance plans that keep the new system clean, efficient, and under warranty requirements.
Yes. Elisee AC Services LLC holds Texas TDLR Air Conditioning & Refrigeration Contractor license #TACLB145586E and performs residential installation work under that license.
