Commercial HVAC Installation in Houston, TX
Texas TDLR Licensed Air Conditioning & Refrigeration Contractor (#TACLB145586E) designing and installing commercial HVAC systems for Houston offices, retail centers, medical suites, restaurants, and multi-tenant buildings. Proper load calculations, City of Houston mechanical permits, and equipment selected for Houston’s high humidity and long cooling season.
Commercial HVAC Installation Built for Houston Conditions
Houston’s climate and building stock demand more than a standard equipment swap. High outdoor humidity, long cooling seasons, and a mix of older buildings and new construction mean systems must handle both sensible and latent loads correctly. We design and install commercial HVAC systems that perform under these real-world conditions while meeting City of Houston mechanical code requirements.

How Commercial HVAC Installation Works in Houston
A structured process from initial site evaluation through final commissioning and City of Houston inspection.
Site Evaluation & Needs Assessment
We visit the property, review existing equipment, roof structure, electrical service, duct condition, and occupancy patterns. For tenant build-outs or new construction we review plans and coordinate with the general contractor or property manager.
Load Calculation & System Design
Commercial load calculations are performed using Houston climate data so both temperature and humidity removal are sized correctly. We recommend equipment type, capacity, and zoning strategy that fit the building’s actual use rather than a rule-of-thumb tonnage.
Permitting & Project Scheduling
We prepare and submit the City of Houston mechanical permit application. When structural or electrical upgrades are required, we coordinate with the appropriate trades. A clear installation timeline is provided so building management can plan around the work.
Installation & Commissioning
Licensed technicians install the equipment, connect refrigerant and electrical lines, modify or replace ductwork as needed, and commission the system. Airflow, refrigerant charge, controls, and safety devices are verified before the system is turned over.
Final Inspection & Handover
We schedule and meet the City of Houston mechanical inspection. After approval we walk the property manager or owner through system operation, filter locations, thermostat programming, and recommended maintenance intervals.
Our Cypress headquarters is roughly 25–30 miles from most central and west Houston commercial districts, allowing reliable same-day site visits and coordinated equipment delivery.
City of Houston Commercial HVAC Installation Requirements
Key regulatory points property managers and owners should know before starting a commercial HVAC project inside Houston city limits.
Is a mechanical permit required for commercial HVAC installation in Houston?
Yes. The City of Houston requires a mechanical permit for new commercial air-conditioning installations, replacements of existing systems, and most alterations. Work must be performed by a TDLR-licensed contractor registered with the City.

Who can pull the mechanical permit?
Only a contractor holding a valid Texas TDLR Air Conditioning & Refrigeration license (Type A or B as applicable) who is also registered with the City of Houston Mechanical Section can pull the permit. Property owners cannot pull their own mechanical permits for this work.

Are inspections required after installation?
Yes. Mechanical inspections are required. Depending on the scope, this can include cover, grille seal, and final inspections. The system must pass inspection before the project is considered complete.

Do larger commercial systems (chillers, AHUs) have additional requirements?
Yes. Installation or replacement of commercial chillers or air-handler units typically requires a mechanical permit with plan review and inspection. Fees and documentation scale with tonnage and project complexity.

Houston Commercial HVAC Installation FAQ
Smaller split-system or single-RTU projects can often be completed in one to three days once equipment is on site. Multi-unit rooftop replacements, VRF systems, or projects requiring structural or electrical upgrades typically take longer and are phased to limit business interruption. A detailed timeline is provided after the site evaluation.
Yes. We pull the required mechanical permit as a TDLR-licensed contractor registered with the City of Houston and coordinate the necessary inspections.
We install packaged rooftop units, commercial split systems, VRF/VRV systems, and related ventilation equipment. Equipment is selected based on building load, roof structure, electrical capacity, and the need for zoning or humidity control.
Houston’s high outdoor humidity creates a large latent load. Systems that are oversized or that short-cycle often leave indoor spaces cool but damp. Proper load calculations and equipment selection that address both temperature and moisture removal are essential for comfort and indoor air quality.
Yes. We routinely schedule crane lifts, cutovers, and major work outside normal business hours when the property requires it. This is discussed and confirmed during project planning.
Building plans or square footage by zone, existing equipment details, electrical service information, roof access notes, and preferred operating schedule help us prepare a precise proposal. A site visit is almost always required for commercial projects.
Yes. We provide commercial HVAC maintenance plans designed to protect the new equipment, maintain efficiency, and catch issues before they become expensive failures.
Yes. Elisee AC Services LLC holds Texas TDLR Air Conditioning & Refrigeration Contractor license #TACLB145586E and performs commercial installation work under that license.
