 Trustindex verifies that the original source of the review is Google. I was recommended to Grays by a friend of my wife that said they were so friendly and helpful. I just had a consultation about possibly replacing our HVAC system and both comments were true. From booking the appointment to meeting with the technician it was a very positive experience.

 Trustindex verifies that the original source of the review is Google. After 5 visit from a very prominent AC company that you see driving in vans all over Las Vegas, I am speechless and incredibly impressed and have had the great privilege of meeting and working with Mike Claus and his team of experts.

Each specialist was Unbelievably kind, considerate, clean, neat and kept me updated at each stage of this furnace repair. What an unexpected beautiful experience.

This team arrived at 8 o’clock in the morning and left at 7 PM and they couldn’t have been more kind and more relaxed for their long day.

In the attic at 112 degrees for 11!hours!!! Yep, I said attic at 112 degrees, I felt so bad that they had so much work to do but they did it with Grace and honor.

1 million times recommend Grays … WE LOVE YOU!!!!

Facilities We Serve

We specialize exclusively in light commercial HVAC, meaning we understand the unique demands of local, day-to-day businesses. We proudly service:

Retail and Shopping Centers

Strip malls, attached storefronts, free-standing retail boutiques, clothing shops, electronics stores, and convenience stores.

Food Service and Hospitality

Restaurants, casual dining, cafes, diners, local bars, pubs, delis, and specialty food stores.

Professional Offices and Services

Small single or low-story office buildings, multi-tenant office suites, local banks, financial branches, law firms, accounting offices, and real estate agencies.

Medical and Healthcare

Small medical clinics, urgent care centers, dentists, specialized doctors' offices, veterinary clinics, and assisted living or small condo complexes.

Specialized Spaces

Local gyms and fitness centers, community centers, churches, small daycare facilities, and small light-duty warehouses or office-warehouse hybrids.

Commercial Heating Systems

Winter nights in the Vegas valley can get surprisingly cold. A failing setup can freeze pipes and force you to close your doors. We keep your building warm, safe, and fully operational with robust heating systems.

Maintenance & Repair

Don't wait for a total breakdown. Our routine hvac maintenance and comprehensive maintenance services stop small issues from becoming expensive emergencies. Our repair teams troubleshoot and fix standard furnaces, standard boilers, and light-duty commercial boilers right the first time.

Replacement

Commercial heating equipment doesn't last forever. We replace old infrastructure with modern hardware, including high-efficiency commercial heat pumps, calculating exactly what your building needs so you never overpay for capacity.

Installation

Building out a new facility? We handle installations from the ground up. We coordinate with your project managers to ensure the ductwork and equipment are installed on schedule and strictly up to code.

Retrofitting

If you are upgrading an older building, we specialize in retrofitting smart hvac technology into your existing infrastructure, saving you massive remodeling costs.

Commercial Cooling Systems

A hot, stuffy building in the middle of a Nevada summer is a huge liability. Reliable air conditioning is absolutely non-negotiable. While the massive mega-resorts on the Strip rely on heavy-duty industrial chillers and cooling towers, your local business requires perfectly sized air conditioning units designed specifically for your square footage.

Maintenance & Repair

We service and repair critical commercial refrigeration systems and general facility refrigeration to protect your perishable assets—which is essential for Las Vegas restaurants, cafes, and specialized stores when the temperatures spike.

Replacement

When it’s time to retire an inefficient cooling unit, we handle the safe removal of your old equipment and install modern, high-efficiency rooftop units with minimal disruption to your daily operations.

Installation

Proper sizing is everything in our climate. We install complete setups, from powerful air handlers and air handling units to highly efficient variable air volume systems—including standard variable air volume (vav) systems—that precisely match your building's load requirements.

Retrofitting

Upgrade your cooling capacity without starting from scratch. By upgrading older wall thermostats to advanced smart thermostats, you can drastically lower your peak summer cooling costs.

Our Emergency Response Process

Rapid Dispatch

We receive your call for hvac emergency response and dispatch the nearest technician immediately.

Precise Diagnostics

We perform thorough ac troubleshooting to pinpoint the exact failure point.

Instant Repair

We execute emergency cooling repair on the spot using fully stocked service vehicles.

Commercial Evaporative Coolers

For small, open warehouses or specialized spaces in our dry desert climate, evaporative coolers can flood your space with naturally cooled air at a fraction of the operating cost. For facilities needing the exact opposite treatment—like indoor growing operations or archival storage—we also install and service commercial dehumidifiers for strict humidity control.

Commercial Mini-Split Systems

Sometimes you only need climate control in specific zones—like a hot kitchen, a glass-walled conference room, or an IT closet. Mini-splits give you precise, independent temperature control right where you need it, making them perfect for creating dedicated zoning systems.

Ducted

We install ducted mini-splits that hide seamlessly in your ceiling or bulkheads, delivering targeted air through discreet vents without overhauling your main infrastructure.

Ductless

Need a fast solution for a problematic room? Ductless wall or ceiling cassettes can be installed quickly, bypassing existing ducts completely while delivering whisper-quiet performance.

Commercial Ventilation Systems

Your indoor air quality directly impacts the health and safety of your employees and customers. Stale air, kitchen odors, and airborne dust need a way out. We install and service heavy-duty ventilation systems, high-capacity ventilation fans, and advanced air filtration systems equipped with commercial-grade air filters to ensure your facility maintains healthy airflow.

Makeup-Air Systems

If your facility runs powerful exhaust fans—like local restaurant kitchens or small manufacturing floors—you are pulling massive amounts of air out of the building. We install makeup-air units and integrate them directly into your broader building automation systems and energy management systems to pull in fresh, tempered air and perfectly balance your building’s pressure.

Serving the Entire Las Vegas Valley

We provide residential ac repair and commercial ac services throughout Las Vegas, North Las Vegas, and Henderson. Wherever you are in the valley, expert help is minutes away.

How often should Las Vegas commercial HVAC systems be maintained?

Because of the extreme summer heat and heavy desert dust, systems in the Las Vegas Valley require preventative maintenance at least twice a year. High-demand environments, like restaurant kitchens or medical clinics, should be serviced quarterly.

What is the typical lifespan of a commercial rooftop unit (RTU) in the desert?

While RTUs generally last 15 to 20 years, the intense Vegas sun and constant summer usage can shorten that lifespan to 12-15 years without strict maintenance.

Will upgrading to smart HVAC technology actually save my small business money?

Yes. Implementing smart thermostats gives you precise control over your energy usage, preventing systems from running at full capacity after your store or office closes, which drastically lowers your NV Energy bills.

How do I know if my restaurant or retail space needs a makeup-air unit?

If your building suffers from heavy front doors that are hard to pull open, lingering kitchen odors in the dining room, hot drafts, or exhaust fans that don’t seem to pull air effectively, you likely have negative air pressure and need a makeup-air unit.

What is the difference between VAV systems and standard air delivery?

Variable Air Volume (VAV) systems vary the amount of airflow supplied to different zones based on current temperature needs, whereas constant volume systems deliver a steady amount of air. VAV systems are highly energy-efficient for office suites dealing with shifting sun loads throughout the day.

Can we improve our indoor air quality without replacing our entire system?

Absolutely. We can upgrade your current setup by installing higher-rated air filters to catch fine desert dust, integrating UV light purification, or adding better ventilation fans to your existing ductwork to cycle in more fresh air.

Why are our small business energy bills so high in the summer?

High energy bills usually point to an aging system, dirty coils clogged with dust, low refrigerant, or an air conditioning unit that is the wrong size for your square footage. Routine maintenance is the fastest way to restore efficiency.

Do you provide emergency repair for refrigeration systems?

Yes. We understand that failures in commercial refrigeration can ruin inventory and shut down a restaurant in a matter of hours. We offer rapid response times across the Las Vegas Valley to get your critical systems back online.

Keep Your Las Vegas Facility Running at Peak Performance

Don’t let an aging rooftop unit or a failing ventilation system compromise your business. Whether you need a walk-in cooler repaired, a routine maintenance contract for your strip mall, or a complete system retrofit for your office, Grays LLC is your reliable partner in the Las Vegas Valley.
