Day & Nite Commercial HVAC Services — Keeping Houston Comfortable, Efficient, and Always Running

In Houston, HVAC isn’t just a convenience — it’s critical. With triple-digit heat, soaring humidity, and relentless pressure on commercial spaces, you need more than basic cooling. You need serious HVAC systems, fast response times, and a team that understands how this city operates. At Day & Nite, we deliver all of that — and more. We design, install, repair, and maintain commercial HVAC systems across Houston and the surrounding areas, keeping restaurants, hospitals, offices, retail spaces, and manufacturing facilities comfortable, compliant, and fully operational.

From Downtown to The Woodlands, Katy to Baytown, we’re the team you call when the A/C stops, the air gets stale, or the energy bills start climbing.

HVAC Solutions Built for Houston’s Climate and Your Business

This isn’t mild weather we’re dealing with. Houston’s climate hits hard, and if your HVAC system isn’t built for it, you’re going to feel it fast. That’s why we don’t deal in off-the-shelf setups. Our team designs and engineers HVAC systems tailored to your building’s structure, your airflow needs, your energy goals, and your usage patterns. Rooftop units, split systems, make-up air, exhaust fans, kitchen hood integration — we build it right the first time, so it lasts.

Professional Installations with Zero Guesswork

Opening a restaurant in Midtown? Expanding a medical facility in Pasadena? Swapping out outdated rooftop units in Spring? We handle the whole process — permitting, load calculations, ductwork, controls, and coordination with GCs and subs. Our install crews move fast and keep things clean. No delays. No cut corners. Just a seamless install that delivers the performance you paid for — and sets your HVAC up for years of efficient operation.

Emergency Repairs — 24/7 HVAC Support Across Greater Houston

When your HVAC goes down in July, every second counts. Customers walk out. Product spoils. Staff starts sweating — and so do your margins. That’s why Day & Nite runs a 24/7 emergency HVAC service team across the Houston metro. Our techs are trained to handle every make and model, and our vans are stocked with critical parts so we can get in, diagnose fast, and restore service without delay. Whether it’s a failed compressor, frozen coils, a blown motor, or a rooftop issue, we’ll get it fixed — no excuses.

Preventative Maintenance That Pays Off in Performance and Peace of Mind

In this climate, preventative maintenance isn’t optional — it’s survival. Our PM programs are engineered to prevent breakdowns, cut energy waste, and help you plan for system upgrades before the emergency hits. We clean coils, test airflow, calibrate thermostats, inspect belts and motors, change filters, log performance data — everything it takes to keep your HVAC system running strong, efficient, and reliable all year long.

We Serve All of Houston’s Commercial Sectors

From Fortune 500 HQs to neighborhood cafés, we handle HVAC for every kind of operation:

• Restaurants and food halls

• Hotels, resorts, and event venues

• Hospitals, urgent care centers, and senior living

• Schools, colleges, and universities

• Office towers and business parks

If it’s got people in it — or product that needs climate control — we’re the ones who keep it livable.

That’s why we show up with more than just tools — we bring insight, experience, and urgency.
