Our Commercial HVAC Services
A full range of commercial heating, cooling, and air quality work for businesses across North Texas.
Commercial Air Conditioning
Offices, retail stores, restaurants, salons, dental offices, and gyms. If you run a business in McKinney and the AC stops working, we can probably help. Rooftop units are the big ones around here, but we also handle split systems, packaged units, and anything multi-zone. Most calls we get, the issue isn’t mysterious—a capacitor, a contactor, low refrigerant, a clogged drain line. We tell you what’s wrong, what it’ll cost you, and you decide.
Bigger jobs get more conversation, obviously. However, you’re not going to get the “your compressor is shot, the whole unit needs to go” routine when really it’s a $180 fix. That’s not how we work. If a smaller repair makes sense, we’ll just do the AC repair and get you back open. For smaller spaces, additions, or buildings without ductwork, a ductless mini-split system is sometimes the smarter call than tying into a central system that’s already maxed out.
Commercial Heating
We also do furnaces, heat pumps, and packaged heating units on the commercial side. Honestly, most of the heating problems we see on commercial jobs come down to one of two things. Either the system was wrong for the building from the day it got installed, or nobody’s looked at it in five years, and it’s clogged up with stuff that should’ve been cleaned out twice a year.
We’ll figure out which one you’ve got, and if it’s a replacement, we actually do the load calculation. You’d be surprised how many people eyeball the old unit and slap in a replacement of the same size. Buildings change. Use changes. Get it sized right, or you’ll be calling someone else in three years.
Commercial Indoor Air Quality
Air quality matters more in a commercial space than people give it credit for. Your staff is breathing it for eight hours a day. Your customers walk in and decide in about ten seconds whether your place feels fresh or musty. Some industries (food, medical, daycare) actually have code stuff to worry about.
We do commercial air filtration, UV lights, ventilation upgrades, and duct cleaning. If you’ve got a smell you can’t track down, humidity that won’t behave, or your AC is running constantly because it can’t keep up with the moisture, that’s where we start. We’ll come out, look at what’s going on, and give you a real indoor air quality recommendation. Not a sales pitch for the most expensive thing we sell.
New Construction HVAC
We work with general contractors and developers on new commercial construction projects across North Texas. Office buildings, retail spaces, restaurants, medical buildings, churches, whatever you’re putting up. We handle the full scope: HVAC system design and load calculations early in the project, equipment selection that fits the budget and the building’s actual use, installation that doesn’t hold up the rest of the trades, and commissioning at the end so everything works the way it’s supposed to before you hand over the keys.
Most commercial new construction HVAC headaches come from systems that were specced wrong or installed in a rush. We don’t do either. Clear timelines, real coordination with the GC, and an HVAC system that’s right for the building from day one.
Preventive Maintenance Plans
Commercial systems run way more than residential. Way more hours, way more people, way more dust, grease, and everything else getting pulled into them. So they break. And they always break at the worst possible moment. Friday at 4 pm, Sunday brunch, the day of your big event.
Maintenance doesn’t fix every problem, but it catches most of them before they turn into a closed-for-the-day situation. Our maintenance plans cover inspections, filter swaps, coil cleanings, refrigerant checks, the works. Plus, you get priority if something comes up. Compared to what one bad afternoon of being closed costs you, the math isn’t close.
Industries We Serve
We work on commercial HVAC for all kinds of businesses in and around McKinney. A few of the most common:
- Restaurants and food service. Walk-in coolers, hot kitchens, packed dining rooms, grease in the ductwork. Restaurant HVAC has its own thing going on, and we get it.
- Retail stores. You can’t sell anything if customers don’t want to be in the building. Storefront cooling matters, especially in summer when somebody walks in from a 102-degree parking lot.
- Offices and professional buildings. Comfort directly affects how much work actually gets done. Nobody’s closing deals when half the office is sweating, and the other half is wrapped in a cardigan.
- Medical and dental offices. Tighter requirements on temperature and humidity, sometimes filtration too. Patients and staff both notice when something’s off.
- Salons, spas, and gyms. High occupancy, high humidity, lots of body heat. Different challenges from a typical office, but solvable.
- Churches and community spaces. Big open volumes, irregular use, often older buildings with original ductwork that’s seen better days.
- Schools and daycares. Indoor air quality is a real concern here. We’ve seen what happens when ventilation gets ignored.
- Property management. We work with property managers across multiple buildings and can keep service records straight across the whole portfolio.
If your business isn’t on this list, ask us anyway. Most commercial HVAC systems are more similar than they are different.

Why Choose Adon Complete for Commercial HVAC
- We answer the phone. Especially after hours. Especially in summer. The 2 am call from a panicked restaurant owner is something we expect, not something we dread.
- Real quotes, real numbers. You’ll know what something costs before we start. If we run into something unexpected mid-job, we stop and talk to you about it. No surprise charges on the invoice.
- We service every major brand. Trane Comfort Specialist, but we work on Lennox, RunTru, Carrier, Daikin, Mitsubishi, whatever you’ve got up there. You don’t have to change brands to work with us.
- 15+ years in North Texas. We know the climate, the equipment that holds up here, the equipment that doesn’t, and the local code stuff that trips up out-of-town contractors.
- We don’t oversell. If a $300 repair will get you another five years out of the unit, we’ll tell you. If it’s truly for a new AC installation, we’ll tell you that too, with real math you can hand to your accountant.
Frequently Asked Questions
How often should commercial HVAC be serviced?
At a minimum, twice a year. Once in spring, before AC season hits, and once in fall, before heating kicks on. Some commercial systems require quarterly service, depending on the building’s operations. Restaurants, medical offices, and high-occupancy spaces usually benefit from more frequent visits than a standard office.
How long do commercial HVAC systems last?
Commercial AC units typically last 15 to 20 years, and commercial furnaces 20 to 25 years. That said, we see plenty of units that didn’t make it past 10 because nobody maintained them, and plenty that hit 25 because somebody actually took care of them. The big variable is maintenance.
Do you offer after-hours commercial service?
Yes. We answer the phone after hours, on weekends, and on holidays. If your AC quits at 7 pm on a Saturday in July, we’re not going to make you wait until Monday morning.
Do you work on rooftop units?
Yes, rooftop package units are the most common commercial setup in McKinney, and we work on them constantly. Single-zone, multi-zone, gas/electric, heat pump, you name it.
How much does commercial HVAC installation cost?
It depends heavily on the building’s size, the required tonnage, the type of system, and the complexity of the installation. A 5-ton rooftop replacement on an easy roof access is a very different job from a 20-ton multi-zone install with new ductwork. We come out, look at what you’ve got, and give you a real quote before any work starts.
Do you handle emergency commercial repairs?
Yes. Commercial emergencies get priority routing, and we’ll get a tech to you as fast as we can, including after hours. If you’re a maintenance plan customer, you go to the front of the line.
