Maximize Rooftop Unit Performance
Efficiency, Control, and Comfort
Performance upgrades like variable frequency drives (VFDs), advanced controls, and economizer integration can make a big difference in how your rooftop ac unit operates day to day. By optimizing airflow, reducing energy waste, and improving temperature control, these enhancements can extend equipment life while lowering operating costs.
Reinforce Rooftop Unit Protection
Safeguard Your Rooftop HVAC
ETS delivers durable protective solutions to help your rooftop HVAC withstand hail, moisture, and long-term environmental wear. From hail guards and weatherproof enclosures to roof screens and conduit protection, we engineer safeguards that defend your investment and keep your building’s systems running strong year-round.
đź’ˇ ROOFTOP UNIT Retrofit Advantages
Why Retrofit Instead of Replace?
You should consider retrofitting your rooftop unit when it shows signs of:
-
Rising energy costs
-
Outdated controls or technology
-
Consistent performance but reduced efficiency
-
Budget or time limitations for full replacement
-
A need to meet new building or sustainability standards
Retrofitting is ideal when your rooftop unit still runs reliably but no longer meets modern efficiency standards. Instead of a costly replacement, retrofits upgrade key components—like drives, sensors, and controls—to boost comfort, cut energy use, and extend system life. A retrofit keeps your RTU operating smarter and longer without disrupting business or breaking the budget.
Lower Upgrade Costs
Retrofits are a cost-effective alternative to replacement, giving you modern performance at a fraction of the investment.
Better Energy Efficiency
New components like VFDs, sensors, and economizers help cut operating costs while reducing strain on older systems.
Smart Technology Integration
Add advanced controls, monitoring, and automation features to your existing RTU—no full system swap required.
Extended Equipment Life
Retrofits restore efficiency and reliability, extending the lifespan of your rooftop HVAC system by years.
Sustainable Building Choice
Avoid unnecessary waste and align with sustainability goals by upgrading instead of replacing.

Frequently Asked Questions
Top performance upgrades include:
-
Variable Frequency Drives (VFDs)
-
Smart thermostats
-
Noise reduction kits
-
Energy Recovery Ventilators (ERVs)
-
Zoning controls
-
Demand Controlled Ventilation (DCV)
VFDs adjust motor speed to match real-time demand instead of running fans at full power. This reduces energy waste, cuts component wear, and can lower utility costs by up to 30%.
Most upgrades deliver a one-to-three-year ROI through lower utility bills, fewer service calls, and extended equipment life.
Yes. With an integrated building automation system, you can monitor, adjust, and diagnose rooftop HVAC performance from secure web or mobile devices.
Yes. Most modern RTUs integrate with smart thermostats or full BAS. ETS installs and programs these controls to improve comfort, scheduling, and energy management.
Absolutely. ETS upgrades existing RTUs with VFDs, economizers, and smart controls to meet current performance and energy goals without full replacement.
Helpful additions include hail guards, coil screens or louvers, bird screens, rooftop screen enclosures, snow diverters, weatherproof enclosures, and UV protection shields. These protective systems help safeguard your rooftop AC units from impact, debris, and harsh weather exposure while maintaining proper airflow and service access.
Hail guards protect condenser coils from impact damage that can cause refrigerant leaks, compressor failure, and costly downtime.
Roof screens block debris and shield units from wind, hail, and visual exposure while preserving service access. ETS custom-designs screens to fit your layout and local codes.
Enclosures shield sensitive components from rain, snow, and corrosion, extending system life and reducing maintenance by preventing moisture intrusion and rust.
Properly engineered accessories maintain required airflow and help keep components clean and unobstructed, supporting consistent performance.
Yes. ETS designs hail guards, roof screens, and line enclosures around your building’s layout, exposure, and maintenance needs for a precise, non-generic fit.
ETS commissions each project by measuring airflow, verifying control sequences, and testing power draw to confirm efficiency and comfort gains.
