Expert Commercial HVAC Repair, Installation & Maintenance in the River Valley
When you operate a business, your commercial heating and cooling system is more than just a convenience—it is a critical asset. At Clark HVAC, we provide elite commercial HVAC services throughout Fort Smith, AR, Spiro, OK, Poteau, OK, and the surrounding River Valley communities. We understand that a malfunctioning air conditioner in a crowded restaurant or a broken furnace in a retail storefront instantly impacts your bottom line. When temperature control fails, productivity drops, inventory can be compromised, and customers walk out the door.
That is why local property managers, facility directors, and business owners trust Clark HVAC for their commercial heating and cooling needs. From emergency commercial AC repair to massive rooftop unit (RTU) installations, our licensed commercial technicians deliver fast, code-compliant, and energy-efficient solutions designed to keep your doors open and your overhead low.
Comprehensive Commercial HVAC Repair Services
Commercial HVAC systems are significantly more complex than residential units, requiring specialized training, heavy-duty parts, and advanced diagnostic tools. Our team is equipped to troubleshoot and repair all major brands of light and heavy commercial equipment.
When you call Clark HVAC for a commercial repair, we prioritize minimizing your operational downtime. We handle:
Rooftop Unit (RTU) Diagnostics & Repair:
Fixing blower motors, replacing commercial compressors, and repairing economizers to restore perfect airflow.
Commercial Refrigerant Leaks:
Identifying and sealing leaks in heavy-duty commercial AC systems and recharging them to factory specifications.
Airflow & Ventilation Troubleshooting:
Correcting pressure imbalances and ductwork issues that cause hot and cold spots in large office spaces or warehouses.
Commercial Heating Repairs:
Servicing heavy-duty gas furnaces, commercial heat pumps, and electric heating elements to ensure your staff and customers stay warm through unpredictable Oklahoma and Arkansas winters.
Commercial HVAC Installation & System Replacement
If your commercial property is running on outdated, inefficient equipment, you are likely losing thousands of dollars a year in wasted energy and frequent repair bills. Clark HVAC provides comprehensive commercial HVAC replacement and new system design. We calculate your building’s exact heat load to ensure you get a perfectly sized system—neither underpowered nor overworked.
Our installation expertise includes:
Packaged Rooftop Units (RTUs):
Seamless extraction of old units and installation of high-efficiency, multi-stage RTUs.
Commercial Split Systems:
Ideal for retail spaces, strip malls, and standalone offices requiring dedicated, reliable climate control.
Ductless & VRF/VRV Systems:
Variable Refrigerant Flow systems offer the ultimate in energy efficiency and multi-zone temperature control. These are perfect for historic buildings without ductwork, server rooms requiring dedicated cooling, or large offices where different zones require different temperatures.
Industrial Exhaust & Make-Up Air Units:
Crucial for restaurants, commercial kitchens, manufacturing facilities, and auto shops that require constant, safe ventilation and air exchange.
Customized Commercial Preventative Maintenance Plans
The secret to avoiding a catastrophic HVAC failure in the middle of a July heatwave is preventative maintenance. Commercial systems run harder and longer than residential units, making regular tune-ups absolutely mandatory.
Clark HVAC offers tailored commercial maintenance contracts designed around your specific equipment and business hours. Our comprehensive maintenance visits include:
Cleaning heavy-duty condenser and evaporator coils to maximize efficiency.
Calibrating commercial thermostats and building management controls.
Inspecting belts, pulleys, and bearings to prevent sudden mechanical failures.
Checking refrigerant charges and tightening vital electrical connections.
Replacing heavy-duty commercial air filters to maintain pristine indoor air quality.
Industries We Proudly Serve
No two commercial buildings are exactly alike. The ventilation needs of a commercial kitchen are vastly different from the humidity control required in a medical clinic. We proudly serve a diverse range of commercial clients across Fort Smith, Spiro, Greenwood, Van Buren, and Poteau, including:
Retail & Strip Malls:
Keeping shoppers comfortable so they stay longer.
Restaurants & Food Service:
Managing kitchen exhaust and dining room temperatures.
Medical Clinics & Hospitals:
Ensuring strict indoor air quality (IAQ) and temperature standards.
Offices & Corporate Buildings:
Maintaining a productive environment for your workforce.
Warehouses & Industrial Spaces:
Providing robust heating and ventilation for large square footage.
Churches & Schools:
Offering quiet, efficient, and reliable systems for large congregations and classrooms.
24/7 Emergency Commercial Service
HVAC disasters do not wait for Monday morning. If your primary cooling system fails during a massive weekend event, or your heating goes out during a deep freeze, our emergency dispatch team is ready. Clark HVAC offers true 24/7 commercial emergency service to get your business back online as quickly as possible.
