HVAC Replacement & Installs
RTU replacements and new commercial equipment, sized and installed for the building. From assessment to commissioning.
There comes a point when fixing the old system stops making sense and replacement starts paying for itself. The decision is rarely just about a broken unit. It is about energy costs, equipment reliability, system efficiency, and the operational risk of running a building on aging infrastructure. TexTech Services provides commercial HVAC replacement and installation across Texas, handling everything from single rooftop unit replacements to full system overhauls for facilities, schools, and industrial buildings. When the time comes to invest in new equipment, the contractor you choose determines whether that investment pays off or becomes another problem.
Commercial HVAC Replacement Built Around Your Building
Commercial HVAC replacement is not equipment swapping. It is engineering. The right unit for your building depends on the size of the space, the operational load, the existing ductwork and electrical infrastructure, the building's energy profile, and the way the facility actually runs from day to day. TexTech Services approaches every commercial HVAC replacement project as a custom engineering decision, starting with a full on-site assessment and ending with a system designed to deliver the performance your facility needs for the next fifteen to twenty years.
Rooftop Unit Replacement and RTU Installation Across Texas
Rooftop units are the most commonly replaced commercial HVAC equipment, and for good reason. Once an RTU passes its useful service life, every repair becomes a question of how much longer you can keep it running before something major fails. TexTech Services handles RTU replacement projects across Texas for buildings of every size, from single-unit swaps on smaller commercial buildings to coordinated replacement of full rooftop fleets on larger facilities. We work with all major commercial HVAC manufacturers and we size every unit to the actual load of the space it serves, not the spec of the unit that was there before.
Commercial HVAC Installation for New Construction and Retrofit
Whether you are building new or replacing existing equipment in an occupied facility, commercial HVAC installation requires planning, coordination, and execution that minimizes disruption to your operation. TexTech Services handles new construction installations alongside retrofit projects in occupied buildings, working with general contractors, architects, and facility teams to deliver systems that meet design specifications and operational requirements. Our installation crews are trained on commercial equipment specifically, and our project management keeps replacement timelines tight so your building gets back to normal as quickly as possible.
Commercial AC Replacement and Cooling System Upgrades
Commercial air conditioning equipment in Texas works harder than equipment anywhere else in the country, which means it also reaches end of life faster. TexTech Services handles commercial AC replacement across Texas for package units, split systems, and larger cooling equipment. We replace aging systems with modern high-efficiency equipment that delivers better performance, lower energy costs, and reliability your facility can count on through the worst of a Texas summer.
Chiller Replacement and Industrial Cooling Installation
Chiller replacement is one of the largest capital projects a commercial facility will undertake, and the stakes match the cost. TexTech Services handles commercial chiller replacement and installation projects across Texas, working with water-cooled and air-cooled systems from the major manufacturers. Our team manages every phase from load calculation through commissioning, and our installation work integrates new chillers with existing building infrastructure, controls, and piping systems with the precision the equipment demands.
Commercial Heating System Replacement
Commercial heating system replacement is often the right move for older facilities running on outdated gas furnaces or aging heat pumps. TexTech Services handles heating system replacement across Texas, delivering modern equipment that operates more efficiently, integrates with current building automation systems, and meets current energy code requirements. Whether your facility runs on rooftop unit heating sections, dedicated furnaces, or heat pump systems, we deliver replacements designed to handle Texas winters reliably for years to come.
Air Handler and Ductwork Replacement
The equipment is only half of an HVAC system. The air handlers, ductwork, and distribution infrastructure carry conditioned air through your building, and aging or undersized distribution systems can undermine even brand new equipment. TexTech Services handles air handler replacement and ductwork upgrades across Texas, evaluating the complete air distribution path and recommending the work that delivers the best long-term performance for your investment.
Energy Efficiency Upgrades and System Modernization
Modern commercial HVAC equipment operates at efficiency levels that older systems simply cannot match. The difference shows up on every utility bill for as long as the new system stays in service, and it often translates into payback periods short enough to justify the project on energy savings alone. TexTech Services helps facility managers across Texas evaluate energy efficiency upgrades, system modernization, and high-efficiency equipment options that deliver real operational savings rather than marketing claims.
On-Site Assessment and Engineering Process
Every commercial HVAC replacement project at TexTech Services starts with an on-site assessment. We measure the spaces, evaluate the existing equipment, review utility data and operational patterns, and identify the constraints that will shape the right replacement strategy. From that assessment we develop a recommendation that includes the equipment selection, the scope of work, the project timeline, and the operational impact on your facility during installation. The goal is to walk into the project with no surprises and walk out with a system you can rely on.
Installation, Commissioning, and Documentation
Our installation work does not end when the new equipment is set in place. Every TexTech Services commercial HVAC installation includes full system commissioning, performance verification under operational load, integration with existing building controls, and complete documentation of the work performed. Your facility receives equipment manuals, warranty documentation, commissioning reports, and a maintenance recommendation that keeps the new system performing the way it was designed to perform.
