Mechanical Contractor in Dallas: Commercial HVAC, Refrigeration & Rooftop Unit Services

Your rooftop unit quit in July. Your walk-in cooler is creeping warm. Or you’re planning a buildout and don’t know which trade to call first. That’s the job of a Mechanical Contractor in Dallas: one team that looks after every system that heats, cools, moves air, and keeps product cold in your building.

At Xtreme Air Services – Oak Lawn, that’s how we work. Most folks assume our trade is just heating and air. It’s broader than that. We handle HVAC, commercial refrigeration, boilers, kitchen ventilation, ductwork, and the plumbing and electrical work that ties those systems together. Here’s the big idea behind this page. When one accountable team handles the whole mechanical side of your building, problems get fixed faster, and nobody blames another vendor.

We’re fully licensed and insured, with HVAC License #TACLA29023C. Below is a short look at each service so you can figure out which one you need. If you’d rather talk it through, call us at 469-269-6373 and talk to a real person today.

Commercial HVAC Installation Covers New Systems and Full Replacements

Commercial HVAC installation means putting a heating and cooling system into your building from scratch, or pulling out a worn-out one and setting a new one in its place. We do both. A new tenant buildout needs a system sized for how the space will really be used. A retail shop, a dental office, and a gym can share one strip-mall roof and still need very different setups.

End-of-life swaps are just as common in Dallas. Plenty of older retail buildings here still run equipment that’s put in long, hard summers. When that equipment is done, you need a replacement that fits the space you have today, not the one from twenty years ago.

Here’s how a commercial HVAC installation usually goes:

• Site assessment – we look at the space, the roof or mechanical room, and your electrical service.
• Equipment sizing – we match the system to your square footage, the people inside, and the heat your space takes on.
• Installation – we set the equipment and connect ductwork, refrigerant lines, and controls.
• Startup – we fire it up, test it, and show you how it runs.

Sizing is the step people rush the most. Too big, and the system cycles on and off and never pulls out the humidity. Too small, and it can’t catch up on a Texas afternoon. You can read more about planning a new system on our Commercial HVAC Installation page.

That same focus carries through the practical oak lawn guidance our team provides to local families.

Commercial HVAC Repair & Maintenance Keeps Equipment Running

Is your system blowing warm air, making a new noise, or just not keeping up with the afternoon heat? Commercial HVAC repair & maintenance covers both sides of that problem. Repair is the call you make when something’s broken. Maintenance is the regular visit that keeps the next breakdown from happening at the worst time.

Dallas is hard on commercial equipment. Our climate leans heavily toward cooling, so your compressors, fans, and belts run long hours for much of the year. That kind of duty cycle wears parts faster than the national averages you’ll read about online. A system that might coast for years in a mild climate needs closer attention here.

When you call, our licensed technicians start by finding the real cause, not just the symptom. A tripped breaker might be the sign of a failing capacitor. A frozen coil could point to an airflow problem or low refrigerant. We explain what we found in plain English and get your approval before any work starts.

Your employees, customers, and tenants all feel it when the air stops working. We get to you the same day so your business can get back to normal. You’ll find more on what commercial HVAC repair & maintenance includes on our Commercial HVAC Repair & Maintenance page.

Commercial Refrigeration Service Protects Food and Inventory

It’s the middle of dinner service and the thermometer on your reach-in is climbing. Every degree counts. Commercial refrigeration service is about protecting the food and product your business depends on, and keeping you from throwing money in the dumpster.

Dallas has restaurants, grocery stores, and convenience stores packed into nearly every retail corridor. All of them rely on display cases, reach-ins, prep tables, and walk-ins that run nonstop. In our heat, those systems work harder than most, especially when the kitchen or back room gets hot too.

Watch for these early signs that your commercial refrigeration needs a look:

• Temperatures drifting higher than normal, even a few degrees
• Frost or ice building up on coils or around the door
• A compressor that runs constantly or clicks on and off a lot
• Water pooling under or around the unit

Catching these early usually means a smaller fix and less lost product. We’ll find the problem, explain it clearly, and get your equipment holding temperature again so you can get back to running your business. Learn more about commercial refrigeration on our Commercial Refrigeration page.

Rooftop Unit (RTU) Service Supports Dallas Retail Buildings

Look up at almost any strip mall or freestanding store in Dallas and you’ll see them: boxy rooftop units, or RTUs. An RTU is a packaged system that holds the heating, cooling, and air handling in one cabinet on the roof. Dallas has a lot of retail buildings from past decades, and many of those units are getting close to the end of their useful life.

Rooftop unit (RTU) service covers three things. First, inspection, so you know what shape your units are really in. Second, repair, to get a failing unit running again. Third, replacement planning, so you can budget for a new unit before the old one dies on a 100-degree day.

That third part gets skipped a lot. In my view, it’s the most useful conversation a property manager can have with a contractor. If you manage a building with several units, knowing which one is likely to fail next helps you plan instead of scramble. It also helps when you’re talking with tenants or ownership about what’s coming.

Your RTUs sit up there baking in the sun and taking hail all year. A little attention goes a long way. Read more about rooftop unit (RTU) service on our Rooftop Unit (RTU) Service page.

One-Stop Commercial Service Covers HVAC, Refrigeration, and Boilers Together

Most buildings end up with a different company for every system. One for the air, one for the coolers, one for the boiler, a plumber, an electrician. Then something breaks, and each one says it’s the other guy’s problem.

One-stop commercial service fixes that. You get one point of contact for the mechanical systems in your building, plus the plumbing and electrical work that connects to them. Think of the dedicated circuit your new RTU needs, the water lines feeding your boiler, or the controls wiring that tells everything when to run. We handle that work from the mechanical side, as part of keeping your equipment running. General electrical or plumbing work that isn’t tied to your mechanical systems belongs with those trades on their own.

This matters most during a project. A buildout with three or four trade vendors means three or four schedules, three or four sets of questions, and a lot of waiting. With one team, the work happens in the right order and you’ve got one phone number to call.

Fewer handoffs. Fewer surprises. See how one-stop commercial service works on our One-Stop Commercial Service page.

Commercial Kitchen Ventilation Keeps Restaurant Air Systems Code-Ready

Commercial kitchen ventilation is bigger than the hood over your fryer. It’s the whole system that pulls smoke, grease, and heat off your cooking line and brings fresh air back in. That includes the hood, the make-up air that replaces what gets pulled out, and the ductwork that connects it all.

Here’s the difference from its siblings. Exhaust hood installation is just the hood itself, one piece of the system. Exhaust system installation usually means non-kitchen exhaust, like industrial or process air in a shop or plant. Commercial kitchen ventilation is the full package built around a cooking line.

When those pieces don’t work together, you feel it fast. Doors get hard to open. Smoke hangs in the kitchen. Your HVAC fights a losing battle against the heat coming off the grill. And when an inspection is coming up or you’re opening a new spot, a system that isn’t working right can slow everything down.

With so many restaurants across Dallas, we know kitchens get busy and stay busy. We’ll look at how your hood, make-up air, and ductwork work together, then get them balanced and running right. Read more about commercial kitchen ventilation on our Commercial Kitchen Ventilation page.

Boiler Installation Brings Heat to New and Expanding Buildings

You’re putting up a new building, or adding a wing to one you already own, and that space needs heat. Boiler installation is how you get it there. It’s a new boiler system going into a space that never had one before.

That’s what makes it different from boiler replacement. Replacement means taking out an existing boiler that’s failed or worn out and swapping in a new one, usually while keeping the building’s heat going as best we can. With boiler installation, there’s no old unit to remove. You’re starting fresh. That changes the plan, because we’re laying out piping, venting, and controls from the beginning.

Boilers show up a lot in multifamily buildings, hotels, and other places that run a central heating plant. Dallas winters are short, but they can bite hard when a cold front blows through. A boiler that’s sized and set up right handles those cold snaps without a fuss.

We’ll work with your timeline and your other trades to get the boiler in, connected, and tested. Learn more about boiler installation on our Boiler Installation page.

Boiler Repair Fixes Faults Fast to Restore Heat

Boiler repair is about one thing: fixing the problem that’s happening right now. Maybe the boiler won’t fire. Maybe it’s locking out, leaking, or making banging sounds in the pipes. Whatever it is, your tenants or guests are cold, and you need answers.

It helps to know how boiler repair fits next to its siblings. Boiler servicing is a scheduled tune-up, usually a single visit to clean and check things over. Boiler maintenance is an ongoing program with regular visits through the year. Boiler repair is the call you make when something’s already gone wrong.

When we arrive, we start with diagnosis. A boiler problem can come from the burner, the controls, a pump, low water, or a bad sensor. Guessing wastes your time. We track down the actual fault, tell you what we found, and fix it.

We answer the phone around the clock.

A cold building doesn’t wait for business hours, and neither do we. Read more about boiler repair on our Boiler Repair page.

Commercial Preventive Maintenance Reduces Emergency Repair Calls

A lot of facility managers treat maintenance and repair as the same budget line. They’re not. Commercial preventive maintenance is a scheduled program built to cut down on emergency calls in the first place. Repair is what you pay for when that doesn’t happen.

With a maintenance program, we come out on a regular schedule and check the equipment in your building before it has a chance to fail. A typical program can include:

• HVAC and rooftop unit inspections, filter changes, and coil cleaning
• Refrigeration checks on coolers, freezers, and ice machines
• Boiler checks ahead of the cold months
• Kitchen ventilation and exhaust checks

The real value is what you learn along the way. You’ll know which equipment is healthy and which is starting to slip. That makes your annual budget a lot easier to plan.

Here’s my honest take. The best maintenance program is the one that fits your building, not the biggest one on the menu. A small office with two rooftop units doesn’t need the same plan as a restaurant with walk-ins and a hood system. We’ll help you build a schedule that makes sense for your equipment. See what commercial preventive maintenance covers on our Commercial Preventive Maintenance page.

Commercial Ductwork Moves Air Through Your Building

What’s behind your ceiling tiles? In most commercial buildings, it’s a network of ducts carrying heated and cooled air from your equipment to every room. Commercial ductwork is that installed system as a whole. When it’s designed and sealed well, your HVAC does its job. When it isn’t, you get hot spots, weak airflow, and higher energy bills.

It’s easy to mix this up with two related services. Ductwork fabrication is building custom duct pieces for a specific job, like an odd transition or a fitting that has to squeeze around a beam. Sheet metal work is the broader trade, and it covers things beyond ducts, like plenums and flashing. Commercial ductwork is the finished, working system in your building.

We handle commercial ductwork for new construction and for renovations. Renovations are where things get tricky. When walls move and rooms change, the old duct layout often doesn’t match the new space. We’ll lay out ductwork that fits how your building works now.

Good airflow is the quiet part of a comfortable building, and it’s part of having one team look after the whole mechanical system. Read more about commercial ductwork on our Commercial Ductwork page.
