If you run a building in Irving, your heating, cooling, refrigeration, and boiler systems don’t work alone. They share power, water, and controls. That’s why a mechanical contractor matters. It’s one team that sees how those pieces connect. Xtreme Air Services – Irving gives Irving facilities one contractor for HVAC, refrigeration, boiler, and mechanical systems, so you can stop juggling separate vendors for problems that touch each other.

Commercial buildings along the Las Colinas corridor and near DFW Airport run big rooftop units, kitchen refrigeration, and boiler systems. They need care that’s planned together, not patchwork fixes. Below is a short look at each service, with a link to the full details for every one.
We’re a family-owned and operated HVAC, plumbing, and electrical contractor serving Irving and the greater DFW Metroplex. Our licensed, background-checked technicians answer the phone around the clock and get to you the same day.
Call Xtreme Air Services today and talk through your building’s mechanical needs with a real person.
Commercial HVAC Installation Sets Up New Systems Right
Commercial HVAC installation means putting in a new heating and cooling system where your building needs one. That might be a new rooftop unit on a retail space or split systems for a restaurant or office suite. The hard part isn’t lifting equipment onto the roof. It’s the sizing.
Sizing is the step people rush past, and it’s the one that matters most. A unit that’s too small runs nonstop through an Irving July and still can’t keep up. A unit that’s too big turns on and off in short bursts. It wears out early and leaves the air damp and sticky. Our technicians look at your building’s real cooling and heating load first. Then they match the equipment to it.
Newer office and retail builds around Irving often need first-time systems sized for months of Texas summer heat. We plan for that load, not for a mild spring day.
Before we hand anything over, we test the system. We check airflow, temperatures, and controls so it runs correctly from day one. You shouldn’t have to call us back the first hot week. See how we plan a new commercial HVAC installation on our Commercial HVAC Installation in Irving page.
Commercial HVAC Repair & Maintenance Keeps Systems Running
It’s 3 p.m. on a Tuesday in August, and the second floor of your building is getting warm. Tenants are calling. That’s a repair call, and it needs a fast answer.
Commercial HVAC repair and maintenance covers two needs. The first is fixing a unit that’s failed or acting up right now. Our technicians track down the cause, whether it’s a bad capacitor (the part that helps a motor start), a refrigerant leak, or a control problem. Then they get the system cooling again.
The second need is a maintenance visit on equipment you’re worried about. A technician checks belts, coils, filters, and electrical parts. Small wear gets fixed before it turns into a big repair.
This is different from Commercial Preventive Maintenance, covered further down. Repair fixes a problem you have today. Preventive maintenance is the ongoing, scheduled program that aims to stop that problem from showing up in the first place.
Irving’s long, hot summers push commercial systems hard for months at a time. Regular checkups count for more here than in milder places. Learn what a commercial HVAC repair visit looks like on our Commercial HVAC Repair in Irving page.

Rooftop Unit (RTU) Service Covers Irving’s Most Common Equipment
Look up at almost any commercial roof in Irving and you’ll see rooftop units. A rooftop unit, or RTU, is one big box that holds the heating, cooling, and fan parts for the space below. Older light-industrial buildings near the DFW Airport corridor run them. So do many Class A office towers in Las Colinas, often with several units per roof.
RTUs sit in full sun all summer. Roof temperatures climb well past the air temperature, and that heat wears on motors, belts, and electrical parts. Hail and spring storms add dents and debris to the coils.
RTU service covers inspection, repair, and tuning. Our technicians clean coils, check refrigerant, tighten electrical connections, and replace worn belts and parts. They also check the curb and seals where the unit meets the roof. A bad seal can let water into the space below.
If you’ve got a dozen units on one roof, it helps to know which ones are struggling before they quit. We’ll walk you through what we find, unit by unit, in plain English. Read more about RTU service on our Rooftop Unit Service in Irving page.
Commercial Refrigeration Supports Food Service Operations
What happens to your business if the reach-in cooler quits during the dinner rush? For restaurants, grocers, and convenience stores, refrigeration isn’t a comfort item. It’s your inventory and your day’s sales.
Commercial refrigeration covers the wide range of cold equipment a food business runs. That includes reach-in coolers, prep tables, display cases, and the compressors, condensers, and controls that keep them cold. Our technicians service all of it to cut downtime and lower the risk of spoiled product.
Commercial refrigeration is the big-picture service. Walk-in cooler repair and walk-in freezer repair, below, deal with those specific units directly. If you aren’t sure which one fits your problem, just call. We’ll help you sort it out on the phone.
The restaurant and retail density in Valley Ranch keeps refrigeration work steady in that part of Irving. Many of those kitchens run equipment hard from open to close, seven days a week. Dirty condenser coils are easy to miss, and they’re one of the simplest things to fix before they cause a failure. See the equipment we work on at our Commercial Refrigeration in Irving page.

Walk-In Cooler Repair Handles Temperature and Door Issues
A walk-in cooler and a walk-in freezer look almost the same from the outside. Inside, they work differently. Coolers and freezers use different refrigerant setups and defrost cycles, so walk-in cooler repair is its own service, separate from walk-in freezer repair.

Walk-in cooler repair is for the box that holds your produce, dairy, and prepped food at safe fridge temperatures. Call us if you notice any of these:
- The thermometer reads warmer than normal, even with the door shut
- The unit cycles on and off more than usual
- Water or frost shows up around the door frame
- The door doesn’t close tight or the gasket is torn
Our technicians check refrigerant levels, door seals, and evaporator coils. The evaporator coil is the part inside the box that pulls heat out of the air. If it’s iced over or dirty, the cooler can’t keep up.
A worn door gasket sounds minor. I’d argue it’s the most underrated part of the whole box. Warm, humid air leaks in all day, and the system works overtime to fight it. We’ll get your cooler back to a steady temperature. Find more on our Walk-In Cooler Repair in Irving page.

Walk-In Freezer Repair Addresses Frost and Compressor Failures
Frost on the walls, ice on the fan, and a thermometer reading 10 degrees when it should be near zero. Those are freezer problems, and they need freezer know-how.
Walk-in freezer repair focuses on equipment that runs far colder than a cooler. Freezers run colder defrost cycles and have different refrigerant demands, so this is a separate service from walk-in cooler repair. Treating a freezer like a general refrigeration call is how problems get missed.
Freezer trouble usually traces back to two places. The first is the defrost system. A freezer has to melt off coil ice on a timer. If a heater, timer, or sensor fails, ice builds up until air can’t move. The second is the compressor, the pump that moves refrigerant through the system. A struggling compressor may run nonstop, trip a breaker, or make new noises.
Our technicians troubleshoot both, along with fans, drains, and door heaters. They look for the reason a part failed, not just the failed part. Otherwise you’d be calling again next month.
For kitchen and cold storage operators, a freezer that won’t hold temperature puts a lot of product at risk fast. Call us as soon as you see the number climbing. Learn more on our Walk-In Freezer Repair in Irving page.
Commercial Kitchen Ventilation Clears Heat and Smoke
Stand behind a busy grill line in August and you’ll know right away if the ventilation is working. Commercial kitchen ventilation pulls heat, smoke, and grease-laden air away from your cooks and sends it outside. It also brings in fresh air to replace what’s pulled out.
Our technicians design and service these systems for new kitchens and for upgrades to existing ones. The work covers the hood, exhaust fans, ductwork, and the make-up air that keeps the room balanced. Without enough make-up air, doors get hard to open, pilot lights flicker, and smoke drifts into the dining room.
Restaurant corridors in Valley Ranch see steady kitchen ventilation work, from new build-outs to older kitchens adding cooking equipment. Adding a fryer or a second grill changes how much air the hood needs to move. That’s easy to overlook during a remodel.
A good system keeps your kitchen cooler and your staff more comfortable. It also helps your HVAC, since it isn’t fighting heat pouring off the line all day. Read more on our Commercial Kitchen Ventilation in Irving page.

Boiler Repair Fixes Systems That Have Already Failed
Boiler repair is for one situation. Your boiler has already stopped working, started leaking, or begun making noises it never made before.
That’s different from boiler servicing and boiler maintenance, which have their own pages. Repair fixes an active breakdown. Servicing and maintenance are scheduled visits that aim to keep that breakdown from happening at all. A maintenance visit isn’t built to chase down a failure in progress.
Our technicians start by finding the failure point. Common causes include:
- Control or ignition problems that stop the burner from firing
- Leaks at valves, fittings, or the heat exchanger
- Pressure that’s too high or too low
- Pumps or circulators that aren’t moving water
Once they find the cause, they fix it and get heat back to your building.
North Texas cold snaps don’t last long, but they hit hard. They bring short, real spikes in boiler repair calls across Irving. Many boilers sit idle most of the year, then get pushed to full output overnight when a freeze rolls in. That’s when weak parts give out. See what boiler repair involves on our Boiler Repair in Irving page.

Commercial Preventive Maintenance Reduces Unexpected Breakdowns
A repair call fixes something that’s already broken. Commercial preventive maintenance is the other side of upkeep. It’s a scheduled program, set up ahead of time, that checks your equipment before anything fails. That makes it separate from a one-time commercial HVAC repair and maintenance call.
With commercial preventive maintenance, our technicians visit on a set schedule. A plan can cover:
- Rooftop units and other HVAC equipment
- Walk-in coolers, freezers, and other refrigeration
- Boilers, pumps, and other mechanical equipment
- Filters, belts, coils, drains, and electrical connections
Each visit catches wear and small issues before they cause a shutdown. Our technicians walk you through what they checked and what to keep an eye on.
Timing matters here. Irving’s summer heat load runs for months, so we like to reach cooling and refrigeration equipment before the first real heat wave. A unit tuned up in spring heads into summer ready to work. One that’s skipped goes in already tired.
In my view, the hardest part is getting started. Once a schedule is set, it mostly runs itself. Find out how a plan works on our Commercial Preventive Maintenance in Irving page.
One-Stop Commercial Service Coordinates Every Trade
Say your boiler stops firing. The cause turns out to be a bad control wire, and the make-up water line feeding it is clogged too. With separate contractors, that’s three phone calls and three schedules. Each trade may point at the others.

One-stop commercial service puts HVAC, refrigeration, boiler, plumbing, and electrical work under one contractor. We coordinate the full job. A problem that touches more than one trade gets fixed without the delays and finger-pointing.
The plumbing and electrical work here is the kind tied directly to your mechanical equipment. Think condensate lines, boiler feed water, RTU disconnects, and pump wiring. General plumbing and electrical jobs, like fixtures or lighting, are handled by those teams on their own pages.
For you, one contractor means one call, one point of contact, and one team that already knows how your building’s systems connect. You shouldn’t have to juggle vendors for problems that share the same pipes, wires, and controls. See how it works on our One-Stop Commercial Service in Irving page.
Contact Xtreme Air Services now for licensed, background-checked technicians who answer around the clock and get to your building the same day.
Frequently Asked Questions
Common questions about Mechanical Contractor
What does it mean to hire a mechanical contractor instead of separate HVAC, refrigeration, and plumbing companies?
A mechanical contractor handles your building’s connected systems as one job, not several. HVAC, refrigeration, and boiler equipment all share power, water, and controls. When one team sees the whole picture, problems get fixed faster and nothing falls through the cracks between vendors.
How do I know if I need a repair visit or a preventive maintenance plan for my Irving building?
Call for a repair visit if a system has already failed or is acting up right now. Choose preventive maintenance if you want to catch worn belts, coils, or electrical parts before they cause a breakdown. Irving’s long, hot summers make regular checkups worth more here than in milder climates.
Do you serve commercial buildings across Irving, including Las Colinas and the DFW Airport corridor?
Yes, we serve commercial buildings throughout Irving, including the Las Colinas corridor and properties near DFW Airport. These areas run large rooftop units, kitchen refrigeration, and boiler systems that need coordinated care. Our licensed technicians answer calls around the clock and get to your building the same day.
Why do rooftop units in Irving need more attention than equipment in other climates?
Rooftop units sit in direct sun all summer, and roof surfaces run hotter than the air around them. That heat wears down motors, belts, and electrical parts faster. Add hail and spring storms, and Irving roofs put extra strain on this equipment compared to milder regions.
My walk-in cooler and my reach-in units both have problems. Which service handles that?
Commercial refrigeration covers the full range of cold equipment, including reach-ins, prep tables, and display cases. Walk-in cooler and walk-in freezer repair handle those specific units directly. If you’re not sure which fits your issue, call us and we’ll sort it out over the phone.
Who should I call for a failing boiler in a commercial building?
Call a mechanical contractor who handles boilers alongside your HVAC and refrigeration systems. Boilers share controls and infrastructure with other building systems, so one team catches issues the others might miss. This keeps your building running without coordinating multiple separate vendors.
