Day & Nite Commercial HVAC Services — Keeping North Carolina’s Businesses Cool, Comfortable, and Always Operational

Across North Carolina — from Charlotte’s glass towers to Raleigh’s tech corridors, from the coast of Wilmington to the mountain towns near Asheville — commercial buildings can’t afford HVAC downtime. Whether you’re running a restaurant in Durham, managing a hospital in Winston-Salem, or overseeing a school district in Greensboro, you need heating, cooling, and ventilation systems that just work. That’s what we do at Day & Nite.

We’re North Carolina’s go-to partner for commercial HVAC design, installation, 24/7 repair, and long-term maintenance — with solutions built for our state’s unpredictable weather, high humidity, and real-world operating pressure.

Custom HVAC Solutions for North Carolina’s Diverse Businesses

No two buildings are the same — especially not here. One day we’re replacing rooftop units in a Raleigh warehouse; the next, we’re designing a full HVAC system for a new build in Chapel Hill. Our approach is simple: we customize every system based on your square footage, layout, usage patterns, and climate demands. Whether it’s a single rooftop unit or a complex multi-zone system with humidity control, kitchen exhaust, and make-up air — we build it to perform.

Installations That Hit Every Target — Performance, Code, and Deadlines

Time is tight. Pressure is high. And you’ve got stakeholders waiting. That’s why our install teams work clean, fast, and focused. From planning and permitting to crane lifts and final testing, we handle every detail with professionalism. Whether you’re building out a brewery in Cary, upgrading a hotel system in Boone, or modernizing classroom HVAC across a school district — we’ll meet your timeline, your specs, and your expectations without drama.

24/7 Emergency Repairs That Don’t Keep You Waiting

When your AC quits in the middle of July or your heat goes out during a surprise March freeze — every minute counts. Our emergency HVAC repair team operates 24/7 across North Carolina, with fully stocked service trucks and trained techs who fix it right the first time. No vague windows. No waiting days for parts. Whether it’s a failed motor in Mooresville or a leaking coil in Fayetteville, we’re already on the move.

Preventative Maintenance That Keeps Your Business Running

North Carolina’s weather is all over the map. One week it’s swampy humidity, the next it’s freezing rain — and your HVAC system feels all of it. Our preventative maintenance plans are built to handle that stress. We inspect, clean, test, and tune your systems so they don’t break down when it matters most. We log every visit, flag future issues, and keep you informed — so you stay ahead, not behind.

Supporting Every Sector Across the Tar Heel State

From fast-paced kitchens to critical-care hospitals, we support every kind of facility, including:

  • Restaurants, QSRs, and food halls

  • Hotels, resorts, and event venues

  • Healthcare and assisted living centers

  • School districts and higher education campuses

  • Breweries, taprooms, and production kitchens

  • Corporate offices and retail properties

  • Government and municipal buildings

  • Manufacturing and distribution centers

We’re working across Charlotte, Raleigh, Greensboro, Durham, Asheville, Wilmington, Cary, High Point, and dozens of other cities and towns.

Locally Focused. Commercially Driven. Always On Call.

We know what your HVAC system is up against. We’ve worked in 100-year-old buildings with no ductwork, handled storm damage repairs during hurricane season, and helped small businesses recover from surprise system failures. We don’t overpromise. We show up, fix it, and keep you running.

Launching a new concept in Gastonia? Replacing aging rooftop units in Greenville? Managing HVAC for multiple properties in the Triangle?

We’ll design it to fit your needs.
We’ll install it on your timeline.
We’ll fix it when no one else will.
We’ll maintain it like uptime is mission-critical — because it is.

That’s Day & Nite Commercial HVAC — trusted across North Carolina to keep the climate controlled and your business in motion.
