Rooftop HVAC Unit Installation, Explained Straight.
The rooftop unit is commercial Central Texas’s workhorse: shops, offices, restaurants, and metal buildings across the corridor all breathe through RTUs on curbs. Installing one is crane work, curb work, and commissioning work in equal measure, and the business below deserves all three done right, on schedule, without drama.
Installation · Burnet & Central Texas
Commercial Comfort Lives on the Roof
Drive any commercial strip from Burnet to Georgetown and the roofline tells the story: RTUs every fifty feet, quietly carrying the county’s working square footage. The format earns its dominance, zero floor space consumed, service access that never disturbs commerce, straightforward replacement cycles, and installation quality determines everything about the decade that follows: whether the unit sips or gulps electricity, whether the roof stays dry around it, whether the dining room below holds temperature on a July Saturday. Commercial owners feel installation shortcuts directly in operating costs and customer comfort, monthly, for years.
RTU projects are logistics wrapped around craft. The crane day gets choreographed, timing, street access, roof protection, business hours respected, and the curb question settled first, since the curb is the building’s handshake with the machine: existing curbs get honest structural and dimensional assessment, adapters get engineered where new equipment meets old openings, and compromised curbs get corrected rather than built upon. Then the trades converge properly: gas, electrical, controls, and condensate all done to commercial code, duct transitions sealed like the energy bills depend on it, because they do.
Commissioning closes it with commercial seriousness: economizers verified where fitted, staging proven, airflow measured against design, controls integrated with whatever the building runs, and the documentation package delivered, because commercial equipment lives on maintenance schedules and the baseline file starts them right.
Everything about this service gets tuned to where you live. The same failure looks different in a lakefront place at Horseshoe Bay, a nineties ranch house outside Bertram, and a five-year-old build in Leander, because humidity exposure, duct design, and equipment grade differ at each address. Ten years of rooftop unit installation calls across Burnet County and the corridor mean we usually know the local pattern before the panel comes off: what the builder-grade systems in the new subdivisions do at year five, what lake air does to outdoor coils, and what a Hill Country attic does to anything asked to work inside it in August.
Installation
RTU Installation Scope
What a rooftop project actually involves when it is done for the decade rather than the invoice.
Curb assessment and correction
The structural handshake, verified or fixed first. Adapters engineered where generations of equipment meet.
Crane day choreography
Timing, street access, roof protection, and business continuity all planned in advance so the lift itself is boring, which is exactly the goal.
Roof integrity respected
Every penetration flashed and sealed to keep the roof warranty intact, with the work coordinated alongside roofing contractors where the building requires it.
All trades to commercial code
Gas, electrical, condensate, and controls done properly at altitude, torqued, tested, documented.
Transitions sealed seriously
Supply and return junctions verified tight, because RTU efficiency leaks exactly there, into the Texas sky.
Commercial commissioning
Staging, economizer, airflow, and controls proven with readings, delivered as the maintenance baseline file.
Same crew, any hour.
The name is the joke, the 24-hour line is not. If this problem cannot wait, call now and the on-call tech picks up, quotes the visit straight, and rolls a stocked truck.
Why Off Duty
Business Continuity Is Part of the Job
Commercial installation carries an obligation residential work does not: the business below has to keep breathing. Restaurants cannot lose a service window, retail cannot close for a crane, offices need their server rooms respected, and we plan installs around that reality, early lifts, phased swaps on multi-unit roofs, temporary conditioning where the timeline demands, and honest scheduling that treats your revenue hours as constraints rather than suggestions. The corridor businesses that call us back for the second and third units do it because the first one was uneventful, which in commercial work is the highest compliment available.
The RTU conversation also extends naturally to the maintenance agreement, and commercial owners should want it to: rooftop equipment ages by filter discipline, coil condition, and belt-and-bearing attention, and the maintenance contract converts breakdown roulette into scheduled line items. Our commercial preventative program starts many relationships at install week, first-year visits planned before the crane leaves, because the cheapest decade an RTU can give a building starts with its baseline file and a calendar.
Every rooftop unit installation call runs the same four steps we run on everything. You call (512) 925-3090 and a real person answers, any hour of any day. We diagnose with gauges and meters, never with guesses, until the actual cause is proven. Then we explain it straight: the failure, the fix, and the exact price, in plain English, before any work starts. Finally we do the work to spec and verify it under load before the truck leaves. Temperatures checked, pressures checked, paperwork handled. It is the same process that earned the reviews on our reviews page, and it does not change based on the size of the job.
A straight word on money. We do not print teaser prices on this website and we do not do surprise math on invoices. Call, describe the problem, and we will tell you what the visit costs before a truck rolls. When the diagnosis is in, you get the full repair price out loud, before the work starts, and you decide with the real number in front of you.
One honest note about timing. Problems in this category rarely improve on their own, and the price of waiting is usually a bigger bill: the weak part takes a healthy one with it, the small leak becomes a stain on a ceiling, the strange noise becomes a seized motor. Calling early is almost always the cheaper version of the same repair, and the phone consult costs nothing: describe what you are seeing and we will tell you honestly whether it can wait.
As for who shows up: this is an owner-operated shop, so the tech at your door is usually Bryce himself, a second-generation HVAC man with ten years on the tools, licensed, insured, and photographed doing exactly this kind of work in the job gallery. No commissioned salesman rides along, and nobody at this company earns a bonus for talking you into more than you need.
This service runs wherever our trucks do: home base in Burnet, the Highland Lakes from Granite Shoals to Buchanan Dam, down the corridor to Round Rock and Austin, north to Killeen and Temple, and out to the sixteen-county edge at Waco, Boerne, and Fredericksburg. The whole map lives on the service areas page, with drive-time honesty built into every window we quote.

The Standard
How This Work Gets Done Here
Here is the standard this work gets held to, spelled out. First, no guessing: the cause is proven with gauges, meters, and eyes on the actual equipment before a single part is recommended. Second, no padding: the fix that goes on the quote is the fix the system needs, sized and specced properly, with no mystery add-ons riding along. Third, no shortcuts: torque specs, code clearances, and manufacturer procedure all get followed even where nobody will ever look, because that is precisely where corners usually get cut.
And when it is done, it gets proven. Systems get run under real load, temperatures and pressures get checked against spec, and the numbers get recorded so the next visit starts from data instead of memory. You get the plain-English version of what was done and why, the workspace gets cleaned, and the price on the invoice is the price you heard before the work began. Hold us to all of it. Our neighbors in the reviews already do.
Rooftop HVAC Unit Installation Questions
Asked Before We Roll a Truck
Real questions from real Central Texas customers, answered the same way we answer them on the phone: straight.
How disruptive is a rooftop unit replacement to my business?
Managed properly, barely: the choreography exists precisely for this. Typical single-unit swaps get staged so the crane work lands in your quietest window, early mornings for restaurants, off-days where they exist, and the connection craft proceeds overhead while commerce continues below. Interior impact is usually limited to brief control tie-ins. Multi-unit projects get phased so the building never loses all conditioning at once. You get the plan in advance, with the honest timeline, and the standing goal is that your customers never know it happened beyond the improved comfort.
My old RTU sits on a curb from the nineties. Can the new one use it?
Frequently yes, through honest engineering rather than hope. Curb adapters are standard practice for mating current equipment to legacy openings, when the curb itself is structurally sound and the dimensions work, which the assessment verifies before anything is ordered. Compromised curbs, rusted, racked, or wrong for the new footprint, get corrected or replaced as quoted scope, never as a mid-crane surprise. The curb decision also touches roof warranty and structure, and we coordinate with roofing contractors where buildings require it. The handshake gets verified first; everything else stacks on it.
Gas-electric or heat pump RTU for my building?
The classic commercial fork, decided by the building’s meter situation, usage pattern, and the winters honestly. Gas-electric packages remain the corridor default where gas is present, cheap familiar heat, straightforward service. Heat pump RTUs increasingly win on all-electric buildings and efficiency-driven owners, with modern equipment handling Central Texas winters easily. Restaurants with heavy hood makeup air, offices with weekend setbacks, and retail with long hours each push the math differently. We run your building’s numbers both ways and recommend the configuration the arithmetic supports, with the operating projections shown.
What size RTU does my space need?
What the commercial load calculation says, and commercial spaces punish guessing worse than houses: occupancy loads, equipment heat, hood and ventilation requirements, glass exposure, and code fresh-air minimums all enter the math, and the tonnage-per-square-foot folklore misses badly in both directions. Oversized RTUs short-cycle, humidify poorly, and waste demand charges; undersized ones lose the July Saturday when the dining room is full. The calculation reads your actual space and use, ventilation requirements included, and the quote shows its work. Any commercial bid without one is folklore with a price attached.
Do you service what you install, and what about after-hours failures?
Both, structurally: we service everything we install through the commercial preventative program, filters, coils, belts, staging checks on a schedule your equipment actually needs, and the 24-hour line applies to commercial exactly as residential, because a restaurant losing cooling on Saturday night is precisely the emergency this company was named for. Install customers get the baseline documentation that makes every future service visit smarter, and priority standing when the heat dome parks over the corridor and every roof in the county calls at once. The install is the start of the relationship, deliberately.
