Commercial HVAC Installation & Service in East Texas
ETR handles all facets of industrial and commercial HVAC installation, including new construction and replacement of existing equipment, in the Greater East Texas area including: Longview, Tyler, Athens and many more!
Full-Service Commercial HVAC from Design to Installation

Commercial HVAC work is not one-size-fits-all. A small retail space has very different needs than a medical office, warehouse, restaurant, or large industrial facility.
ETR handles commercial HVAC projects across East Texas, including new construction, system replacements, repairs, maintenance, and emergency service calls. Our commercial team works with business owners, property managers, developers, and general contractors throughout Tyler, Longview, Athens, and surrounding areas.
We also have two in-house mechanical engineers and six full-time estimators/designers, which is something a lot of commercial HVAC companies cannot offer internally. Many contractors outsource engineering work. ETR keeps that process in-house from design through installation.
ETR is fully bondable and insured up to $5 million and services all major commercial HVAC system types and brands.
Commercial HVAC Services We Provide
ETR provides commercial HVAC installation, repair, replacement, and maintenance services for businesses and facilities across East Texas.
Commercial HVAC Installation (New Construction)

Our team coordinates directly with owners, contractors, and project managers during the construction process to help keep projects moving on schedule.

ETR installs rooftop units, split systems, VRV systems, chilled water systems, DX systems, and other commercial HVAC equipment depending on the needs of the building.
Commercial HVAC Upgrade & Replacement
Commercial HVAC equipment does not last forever, especially in East Texas heat. Older systems can become expensive to operate and harder to keep running consistently.

Whenever possible, our team works to minimize disruption to day-to-day business operations during installation.
Commercial AC Repair in Tyler, Longview & East Texas
When a commercial AC system goes down, businesses usually need service quickly, especially during the summer.

Our technicians service all major commercial HVAC brands and system types, including rooftop units, split systems, VRF systems, and chilled water applications.

24/7 Emergency Commercial HVAC Service
HVAC problems do not always happen during business hours.
For businesses like restaurants, hotels, healthcare facilities, and industrial operations, after-hours HVAC service can be critical. ETR provides 24/7 emergency commercial HVAC service throughout East Texas to help businesses respond quickly when heating or cooling systems fail.
Commercial HVAC Systems We Install & Service
Rooftop Package Units (RTUs)
Rooftop package units are one of the most common commercial HVAC systems used across East Texas. They are frequently used for offices, retail buildings, restaurants, churches, and other commercial spaces.
ETR services all major rooftop unit brands and installs systems from manufacturers like Lennox, Daikin, and Trane.
Split Systems for Commercial Spaces
Commercial split systems are commonly used in smaller commercial buildings where rooftop equipment may not be practical or possible.
ETR installs and services split HVAC systems for office spaces, retail buildings, and other smaller commercial applications throughout East Texas.
Daikin VRV/VRF Systems
VRV and VRF systems have become more common in commercial applications because they allow for flexible zoning and efficient temperature control across different areas of a building.
ETR is a Daikin VRV installer and services VRV/VRF systems for offices, medical facilities, hotels, and other commercial spaces.
Chilled Water Systems
Chilled water systems are typically used in larger commercial and industrial facilities that require centralized cooling.
Having in-house mechanical engineers gives ETR an advantage when designing and servicing more complex chilled water systems and applications.
Direct Expansion (DX) Systems
Direct expansion, or DX systems, use refrigerant to cool air directly through the HVAC system. These systems are commonly used across a wide range of commercial buildings because of their flexibility and efficiency.

Called ETR about an AC cooling issue within an office. Julian and Cody showed up quickly to resolve the problem. Julian worked hard to fix the issue and Cody was very knowledgeable in his trade explaining what all they were doing to fix the issue. They showed up, diagnosed the problem and resolved it within the hour! The office was already cooling off again before I could get out of there. Highly recommend Julian and Cody!
