Mechanical Contractor in Allen: Commercial HVAC Services – Installation, Repair, RTU & Preventive Maintenance

Your building’s mechanical systems work quietly in the background. They cool your shop, keep your food cold, pull smoke out of your kitchen, and heat the place on the rare freezing night. Xtreme Air Services – Allen is a mechanical contractor Allen business owners can call when one of those systems needs help. Our HVAC License #TACLA29023C is on file and easy to check.

Here’s what we tell almost everyone who calls. Most problems don’t need a big project. They need the right service matched to the right piece of equipment. In Allen, that often starts on the roof, because so many offices and retail centers here run on packaged rooftop units.

Below are ten of our core commercial services, each with a short, plain-English explanation. Find the one that sounds like your problem, then click through for the full details on that service.

Commercial HVAC Installation for New Builds and Full Replacements

Commercial HVAC installation is the big-project work. It means putting new heating and cooling equipment into a whole building. That usually happens in new construction, during a gut remodel, or when the old setup has reached the end of the road.

A lot of Allen’s office and retail space went up between the mid-1990s and the 2010s. Much of it has flat roofs, with the equipment sitting up top. So when an owner decides to replace everything at once, the job covers more than one unit. It covers sizing, duct connections, controls, electrical hookups, and getting every part to run as one system.

Sizing is the step people rush. A unit that’s too big cycles on and off and never pulls enough humidity out of the air. A unit that’s too small runs all day in July and still can’t keep up. We do the load math first. Then we pick equipment that fits how you use your space.

If you’re planning a new build or a full replacement, start with our Commercial HVAC Installation commercial HVAC installation page. It walks you through a project from the first site visit to the day the system starts up.

Commercial HVAC Repair & Maintenance When Something’s Off

It’s 3 p.m. on a Tuesday in August, and your back office is creeping past 85 degrees. That’s where commercial HVAC repair & maintenance comes in. This service covers two things: fixing what’s broken right now, and handling routine service visits when your system needs one.

It’s not the same as a preventive maintenance contract. With repair & maintenance, you call us when something’s wrong or due. With preventive maintenance, we keep a set schedule for you so problems get caught before you ever have to call.

Here are a few signs it’s time to call for commercial HVAC repair & maintenance:

• Warm air coming from vents that should be blowing cold
• Weak airflow in some rooms but not in others
• Grinding, squealing, or banging noises from the unit
• A thermostat that reads one temperature while the room feels like another
• A sudden jump in your power bill with no change in how you use the space

Any one of these can start small and get worse in the heat. We’ll send a technician out, find the cause, and give you upfront pricing before any work starts. See our Commercial HVAC Repair & Maintenance commercial HVAC repair & maintenance page to learn what a typical service visit covers.

Rooftop Unit (RTU) Service for Allen’s Flat-Roof Buildings

Walk past almost any strip center along US 75 or SH 121 and look up. You’ll see metal boxes lined up on the roof. Those are rooftop units, or RTUs. Each one is a complete heating and cooling system packed into a single cabinet. In Allen, they’re the standard setup for flat-roof retail and office buildings.

Rooftop unit (RTU) service is repair and upkeep for that one type of unit. It’s not the same as commercial HVAC installation. Installation is a whole-building project. RTU service usually means one unit is acting up while the rest of the roof runs fine.

That difference matters for your budget and your schedule. A lot of owners assume a failing RTU means replacing the whole system. Often it doesn’t. A bad capacitor, a worn fan motor, a clogged coil, or a refrigerant problem can usually be fixed right there on the roof.

Many of Allen’s RTUs went in during the 1990s and 2000s, so some are nearing the end of their working life. When repairing a unit stops making sense, we’ll tell you straight. Our Rooftop Unit (RTU) Service rooftop unit (RTU) service page explains how we decide between repairing and replacing a single unit.

Commercial Preventive Maintenance on a Set Schedule

What if you could catch problems before they shut you down? That’s the idea behind commercial preventive maintenance. It’s a scheduled program, set up ahead of time, where we visit on a regular rotation to check, clean, and adjust your equipment.

A one-time repair visit is different. Commercial HVAC repair & maintenance answers the call when something has already gone wrong. Commercial preventive maintenance is the plan that keeps those calls from coming as often.

North Texas summers are hard on equipment. Units run long hours for months, often in triple-digit heat on a hot roof. Dirty coils, loose wires, and worn belts add a little extra strain every single day. By August, that strain tends to show up as a breakdown.

A good program catches those small things in spring, before the heavy cooling season, and again before winter. You get a record of what we checked, what we found, and what’s worth watching. If you’re a facilities manager, that record makes planning and budgeting a lot easier.

In my view, this is the most boring service we offer, and that’s exactly why it works. See what a visit includes on our Commercial Preventive Maintenance commercial preventive maintenance page.

Commercial Refrigeration Service for Restaurants and Retail

Setting up a new cooler is one job. Keeping the coolers you already own cold is another job, and that’s what commercial refrigeration covers. It’s the umbrella service for repairing and caring for the cold equipment your business depends on.

Allen’s restaurants, cafes, and retail shops run a lot of refrigeration. When it fails, you’re not just uncomfortable. You’re watching inventory warm up by the minute. Commercial refrigeration service usually covers equipment like this:

• Reach-in coolers and freezers
• Refrigerated prep tables on the cook line
• Display cases in retail and grocery spaces
• Condensing units on the roof or out back

Walk-ins and ice machines have their own service pages, because their problems and fixes are different. The same goes for refrigeration leak detection, which is a focused hunt for lost refrigerant, and for installing brand-new equipment.

When food is on the line, time matters most. We work to get a technician to you the same day so you can get back to business. Learn more on our Commercial Refrigeration commercial refrigeration page.

Commercial Kitchen Ventilation That Keeps the Line Running

A busy kitchen makes heat, smoke, grease, and steam all day long. Commercial kitchen ventilation is the system that moves all of that out of the building and keeps fresh air coming in. Without it, your cooks are miserable, and the dining room starts to smell like the fryer.

Allen’s dining scene keeps growing, especially around Watters Creek at Montgomery Farm and The Village at Allen. New restaurants open, and older spaces get new tenants with different menus. Each change can call for a kitchen ventilation setup that fits the new cooking load and passes fire and health inspections.

Two related services often come up in the same conversation. Exhaust hood installation is the hood itself, the canopy over your cooking line that captures smoke and grease. Make-up air systems bring fresh air back in to replace what the hood pulls out. Commercial kitchen ventilation looks at the whole picture and makes sure air moves in and out in balance.

That balance matters more than people expect. If it’s off, doors can slam, pilot lights can act up, and the hood won’t pull well. Get the full rundown on our Commercial Kitchen Ventilation commercial kitchen ventilation page.

Boiler Repair When Your Heat Quits in a Cold Snap

Boiler repair, boiler servicing, and boiler maintenance sound alike, but they’re three different calls. Boiler repair means something is broken and you need heat back now. Boiler servicing is a one-time tune-up and inspection visit. Boiler maintenance is an ongoing, scheduled program.

This section is about the urgent one.

Here’s the catch with boilers in North Texas. Our winters are mild most years, so a boiler may sit idle or run lightly for months at a time. Small problems can hide during those quiet stretches, like a sticky valve, a worn pump, or a pressure issue. Then a hard freeze rolls in, the boiler finally has to work, and the problem shows up all at once.

When that happens, you’ve got tenants or staff in a cold building, and you need answers fast. We’ll find out why the boiler isn’t heating, explain the fix in plain English, and get your heat back on. No guesswork.

Our Boiler Repair boiler repair page covers common boiler failures and what to do while you wait for a technician.

Building Automation / Controls for Your Mechanical Equipment

Ever wish you could check every piece of equipment in your building from one screen? That’s what building automation / controls can do. It ties your HVAC units, boilers, and refrigeration together so you can watch them, schedule them, and get alerts when something’s wrong.

We keep this work focused on mechanical equipment. That means thermostats, sensors, schedules, and the wiring that tells your units when to run and how hard. It’s not security cameras or general building tech.

Here’s why it helps. Your rooftop units can ease off after closing time instead of cooling an empty store all night. Your walk-in can send a warning when its temperature starts to climb, so you know before you lose product. Your boiler can come on before staff arrive on a cold morning.

For a property manager with several buildings or a lot of units, building automation / controls turns a long list of guesses into real information. You see the problem sooner, and you can call for help before a small issue grows.

Find out what a controls upgrade looks like on our Building Automation / Controls building automation / controls page.

Commercial Ductwork Repair and Installation

One office is freezing, and the one next door is stuffy. Your equipment might not be the problem at all. It could be your commercial ductwork, the network of metal runs that carries air from your units to every room.

Commercial ductwork service covers installing, repairing, and sealing that whole system. Leaks, crushed runs, loose joints, and poor layouts can all waste the air you’re paying to cool. In a flat-roof building, a lot of that ductwork sits in a hot space above the ceiling, so a leak in July means cooled air heading straight into the heat.

Two related services are easy to mix up with this one. Ductwork fabrication is custom-making duct pieces to fit a specific space. Sheet metal work is the hands-on trade behind that fabrication, and it also covers metal parts that aren’t ducts. If you have a leaking duct run or uneven airflow, commercial ductwork service is the right place to start.

We’ll trace where the air is going, find the weak spots, and fix them. Read more on our Commercial Ductwork commercial ductwork page.

Mechanical Design-Build Services for Bigger Projects

Some jobs are too big for a single service call. Maybe you’re opening a new building in Allen, gutting an old one, or upgrading equipment across a whole facility. That’s where mechanical design-build services come in.

With design-build, one team plans the mechanical systems and then builds them. You aren’t stuck passing drawings back and forth between a designer and a separate installer. We figure out what your building needs, design the layout, and carry the job through to startup.

This is also the starting point for work that goes beyond the other services on this page. Mechanical equipment retrofits, building mechanical upgrades, and central plant upgrades all tend to begin with a design-build conversation. The difference between them is mostly scope, from one piece of equipment up to the systems that serve the whole building.

We think having one team own both the design and the install keeps the finger-pointing out of a project. If something doesn’t fit, it’s on us to fix it, not on someone else.
