Air handler units (AHUs) are crucial components in HVAC systems, responsible for regulating and circulating air throughout buildings. As with any mechanical system, AHUs have a finite lifespan and require maintenance, repair, or even replacement over time. However, deciding whether to refurbish an existing unit or replace it entirely can be challenging. Here’s a guide to help you make the best decision for your facility.
Signs It’s Time to Refurbish Your Air Handler Unit
1. Age and Overall Condition
- Age: If your AHU is more than 10 years old but less than 20, it may still have some life left, especially if it has been well-maintained.
- Condition: Units that are generally in good condition but have specific issues, such as a worn-out fan or damaged coils, can often be refurbished.
2. Performance Issues
- Decreased Efficiency: If your AHU’s efficiency has decreased but it still operates without significant issues, refurbishing certain components like motors, fans, or filters might restore its performance.
- Noise and Vibration: Excessive noise and vibration can often be resolved by replacing bearings, belts, or dampers, rather than replacing the entire unit.
3. Budget Constraints
- Cost-Effective Solution: Refurbishing an AHU is typically less expensive than a full replacement. If your budget is tight, refurbishing can extend the unit’s life at a fraction of the cost.
4. Minimal Downtime
- Operational Impact: If your facility cannot afford the downtime associated with a complete replacement, refurbishment can be a quicker, less disruptive option.
Signs It’s Time to Replace Your Air Handler Unit
1. Age Beyond 20 Years
- End of Lifecycle: Most AHUs have a lifespan of 15-20 years. If your unit is approaching or has exceeded this age, replacing it is usually the more cost-effective and reliable option.
- Obsolete Parts: If parts for your unit are obsolete or hard to find, it may be more practical to replace the unit than to keep making costly repairs.
2. Frequent Breakdowns
- High Repair Costs: If your AHU requires frequent repairs, the cumulative costs may outweigh the benefits of refurbishment. Continuous failures can also lead to inconsistent performance and increased energy consumption.
- Recurring Issues: If the same components keep failing, this might indicate a deeper systemic problem that refurbishment cannot address.
3. Poor Energy Efficiency
- Rising Energy Bills: Older AHUs tend to be less energy-efficient, leading to higher operational costs. Newer units are designed with advanced technology that can significantly reduce energy consumption.
- Environmental Concerns: If your facility is focused on sustainability, replacing an older, inefficient AHU with a modern, energy-efficient model can greatly reduce your carbon footprint.
4. Major Renovations or System Upgrades
- Facility Upgrades: If your building is undergoing significant renovations or if you’re upgrading other HVAC components, it might be the right time to replace your AHU as well. A new unit can be integrated more seamlessly into an upgraded system.
- Compatibility Issues: If your current AHU is not compatible with new technologies, sensors, or controls being implemented in your facility, replacing it ensures optimal performance and future-proofing.
