Commercial HVAC Maintenance Plan for Longevity and Efficiency
Preventative maintenance is the single most cost-effective investment for your commercial HVAC system. Routine RTU maintenance extends equipment lifespan, reduces energy consumption, and prevents catastrophic failures.
Comprehensive Commercial Preventative HVAC Maintenance Includes:
- Seasonal start-up and shutdown checks (Spring AC Tune-up / Fall Heating Check).
- Thorough cleaning of condenser and evaporator coils to ensure maximum heat transfer efficiency.
- Inspection of electrical components, including contactors, relays, and wiring.
- Checking and lubricating motors and fan bearings.
- Airflow and ventilation system calibration for optimal indoor air quality.
- Filter replacement on a scheduled basis to protect internal components.
Benefits of a Maintenance Contract:
- Priority service scheduling, often receiving faster service during peak seasons.
- Lower monthly utility bills due to maximized energy efficiency.
- Compliance with manufacturer warranty requirements.
- Detailed reporting on unit condition, helping you budget for future
commercial rooftop unit replacement.
Commercial Rooftop Unit Replacement & New Packaged Unit Installation
The decision to repair or replace an aging RTU is a major financial consideration. Our team provides an honest, comprehensive cost-benefit analysis to guide your decision, focusing on long-term operational savings.
Replacement Analysis Factors:
- Unit Age: Most RTUs last 15-20 years. If a repair is required on a unit over 15 years old, a commercial rooftop unit replacement is often the smarter investment.
- Repair Cost vs. Replacement Cost: We use the industry standard "50% Rule"—if the major repair cost exceeds 50% of the install commercial packaged unit cost, replacement is recommended.
- Refrigerant Type: Replacing outdated R-22 units with systems using modern, compliant refrigerants (like R-410A) provides significant long-term savings.
Installation & Upgrade Services:
- Expert commercial rooftop unit installation using cranes and specialized equipment with minimal disruption.
- Installing new, high-efficiency RTUs that meet the latest IEER and SEER standards.
- Proper sizing and load calculation to ensure the new system perfectly matches your building's thermal demands.
- Integration of modern smart controls and zoning systems for enhanced building management.
