Day & Nite Commercial HVAC Services — Keeping South Florida Cool, Efficient, and Always Operational

South Florida doesn’t let up — not the sun, not the humidity, not the pace of business. In this climate, a commercial HVAC failure isn’t just uncomfortable; it’s a full-stop disaster. That’s where we come in. At Day & Nite, we specialize in high-performance commercial HVAC systems for South Florida’s most demanding environments. From Miami to West Palm Beach, Fort Lauderdale to Homestead, we design, install, repair, and maintain HVAC systems that work when you need them most — always.

Whether you run a beachfront hotel, a school campus, a surgical center, or a fast-paced restaurant, we’re the HVAC partner that shows up with experience, urgency, and results.

HVAC Systems Built for Heat, Humidity, and Heavy Use

South Florida air is thick, salty, and relentless — and your HVAC system better be up to the task. We don’t offer cookie-cutter setups. We custom design HVAC solutions for real-world use, factoring in square footage, humidity load, equipment heat gain, and the daily grind of your operation. Rooftop units, split systems, VRF, kitchen hoods, make-up air, dehumidifiers — we build it all to hold strong in high-traffic, high-heat environments.

From luxury resorts in Miami Beach to corporate buildings in Boca, we engineer comfort and control where it matters.

Installation Done Fast, Done Right, and Done to Code

A smooth install isn’t just about placing the unit — it’s about airflow, permits, ductwork, electrical integration, energy efficiency, and being ready on time. Our crews have done it all: new construction in Coral Gables, retrofits in Pompano Beach, replacements in busy Fort Lauderdale hotels. We work with your GC, your subs, your facility team — or we run the whole job front to back. Either way, we’re in, we’re sharp, and we get it done right the first time.

Emergency Repairs That Happen When You Actually Need Them

A rooftop unit fails at 3 p.m. in downtown Miami. The kitchen exhaust goes down mid-service in Pembroke Pines. Your hospital HVAC goes silent during a heatwave in West Palm — what now?

You call us.
We show up.
We fix it.

Day & Nite runs a 24/7 emergency HVAC response team across South Florida. No slow callbacks. No mystery diagnostics. Just vans fully stocked with real parts and techs who know exactly what they’re doing. We fix it fast and we fix it right, so your business keeps moving.

Preventative Maintenance That Prevents More Than Just Breakdowns

South Florida air destroys neglected HVAC systems — coils corrode, drains clog, ducts grow mold, motors overheat. That’s why we offer maintenance that actually keeps your system healthy. We do it all: full inspections, coil cleaning, motor testing, thermostat calibration, airflow checks, refrigerant pressure testing, filter replacement — all logged, all tracked. We help you avoid shutdowns, lower your energy bills, and stretch your system’s lifespan way past the average.
