FAQs

Frequently Asked Questions About Commercial Rooftop Units

Most commercial rooftop units provide 15 to 20 years of reliable service with proper maintenance. However, actual lifespan depends on factors including equipment quality, operating conditions, maintenance consistency, and local climate. Here in Central Texas, our intense summers put significant demands on RTU cooling systems. Regular maintenance from Area Wide Services helps maximize your equipment's service life and alerts you to developing issues before they become major problems.

We recommend at least two maintenance visits per year for most commercial rooftop units-one in spring before cooling season and one in fall before heating season. High-use facilities like restaurants and healthcare buildings may benefit from quarterly maintenance. Our commercial maintenance programs are tailored to each account's specific equipment and operational requirements.

Short cycling-when your RTU starts and stops frequently-can result from several issues including oversized equipment, refrigerant problems, dirty filters, thermostat malfunctions, or failing electrical components. This behavior stresses your equipment and increases energy consumption. Our technicians diagnose short cycling causes and recommend appropriate repairs.

Yes, Area Wide Services services all major commercial rooftop unit brands. While we're authorized dealers for Armstrong, American Standard, and Mitsubishi, our technicians maintain the knowledge and parts access needed to service Carrier, Trane, Lennox, York, Rheem, and other manufacturers' equipment.

An economizer is a damper system that brings in outdoor air for cooling when conditions are favorable. When outdoor temperatures drop below indoor setpoints, the economizer allows your RTU to provide "free cooling" without running the compressor. Properly functioning economizers significantly reduce energy costs. We inspect and calibrate economizers as part of our standard maintenance service.

Consider RTU replacement when repair costs become excessive, efficiency declines significantly, or the unit can no longer maintain comfortable temperatures. Equipment age, refrigerant type (R-22 systems face phase-out challenges), and available technology improvements also factor into replacement decisions. Our team provides honest assessments to help you make informed choices.

Proper RTU sizing requires detailed load calculations based on building size, construction, occupancy, equipment heat loads, and other factors. Undersized units run constantly without achieving comfort, while oversized units short cycle and waste energy. Area Wide Services performs professional load calculations before recommending equipment sizes.

Yes, we understand that commercial HVAC failures can't always wait for scheduled appointments. Contact us when your RTU stops working, and we'll respond as quickly as possible to restore your system. Commercial maintenance agreement customers receive priority scheduling for emergency situations.

Your maintenance staff can handle basic filter replacements if they have safe roof access and proper training. However, most RTU maintenance tasks require specialized knowledge and equipment. We recommend professional maintenance to protect your equipment warranty and ensure thorough service.

Regular maintenance provides the foundation for RTU efficiency. Beyond maintenance, consider economizer calibration, programmable thermostat upgrades, building automation integration, and addressing ductwork leaks. For older equipment, high-efficiency replacement may offer the best long-term efficiency improvement.

Modern RTUs use R-410A refrigerant, but many older units still operate on R-22, which has been phased out of production. R-22 equipment can continue operating, but refrigerant costs have increased significantly. During our service visits, we can discuss your refrigerant type and options if you have older equipment.

Yes, we can connect compatible RTU controls to building automation systems. Automation integration allows centralized monitoring, scheduling, and setpoint management across multiple rooftop units. Contact us to discuss your building automation goals and equipment compatibility.
