Question Answers

What should I consider when planning an HVAC installation or replacement for my Little Rock business?

Proper design and installation are critical, especially given our local climate. Since 1991, we've specialized in system design-build and installations for commercial and industrial settings. We assess your building's specific needs, factoring in Arkansas humidity to prevent issues like mold growth. Our process includes creating a tailored plan, executing precise installation, and setting up a preventive maintenance program to ensure long-term efficiency and reliability for your investment.

How does your preventive maintenance program work for HVAC systems?

Our program is built on proactive care. We use computerized maintenance tasking to schedule and document all service visits, ensuring no component is overlooked. This includes checking refrigerant levels with our tracking program, inspecting electrical connections, cleaning coils, and verifying system pressures. For our Little Rock clients, this regular attention is key to preventing major breakdowns during our hot summers and catching small issues—like early signs of ductwork moisture—before they become costly repairs.

Can you help with mold concerns in our commercial building's ductwork, a common issue here?

Absolutely. Mold in ductwork often stems from condensation due to improper installation, sizing, or a lack of maintenance. Our team first performs a thorough inspection of your system. We address the root cause, which may involve repairing or replacing sections of our custom-fabricated sheet metal ductwork to ensure proper sealing and airflow. We then integrate a solution into your preventive maintenance plan to monitor humidity levels and coil conditions, helping to prevent mold from recurring in Little Rock's humid environment.
