AHU Refurb - FAQ's
Why should I refurbish my AHU?
When compared to the prospect of replacing your AHU entirely, refurbishment emerges as a more practical and cost-effective option. New Air Handling Units (AHUs) are bound by stringent L2 and ErP regulations, which often translate to larger physical footprints.
This enlargement can introduce complexities, requiring extensive modifications to existing mechanical and electrical infrastructure to accommodate the new unit's size. AHU Refurbishment avoids these challenges, allowing you to maintain operational continuity while enhancing performance and efficiency.
Is my Air Handling Unit underperforming?
Identifying whether your Air Handling Unit (AHU) is underperforming involves recognizing various signs. Elevated CO₂ levels within the area served, compromised thermal comfort for occupants, excessive noise, or persistent odours are all potential indicators of poor AHU performance.
To accurately assess the situation, HALO HVAC offers on-site evaluations, conducting thorough condition surveys of your AHUs. Through these assessments, HALO HVAC delivers invaluable professional insights, pinpointing potential issues and providing actionable recommendations to optimize AHU performance and restore indoor comfort.
Will AHU refurbishment be disruptive?
Ensuring minimal disruption during AHU refurbishment is paramount to HALO HVACs mission. Our team of seasoned experts adopts a strategic approach, coordinating AHU refurbishment works to seamlessly align with your building's operational schedule and shutdown requirements. Leveraging our engineers' flexibility and dedication, we work tirelessly, around the clock, to mitigate disturbances.
In contrast, replacing an air handling unit presents significantly greater disruption to building operations. The intricate coordination of mechanical and electrical services involved in replacement exacerbates downtime and logistical challenges, further underscoring the benefits of Air Handling Unit refurbishment in minimizing disruption.
How long does it take to refurbish an AHU?
The duration of AHU refurbishment varies based on several factors, including the project's scope, the AHU's size, and accessibility constraints.
Smaller AHUs undergoing upgrades like EC plug fan upgrades or coil replacements can typically be completed within a swift timeframe of 1 to 2 days. Conversely, larger AHUs may necessitate slightly more time for comprehensive refurbishment, aligning with the intricacies of their scale and complexity.
How long should my AHU last?
The life expectancy of your air handling unit typically spans between 15 to 20 years from its installation date. Consistent maintenance plays a pivotal role in ensuring optimal performance and extending the system's longevity. External installation exposes AHUs to weathering, potentially shortening their lifespan; however, when appropriately designed and manufactured for the environment, they can still endure for two decades.
It's important to note that individual components within the AHU exhibit varying lifespans. Filters, for instance, typically require replacement every 3 to 6 months as part of a proactive maintenance plan. Meanwhile, components like fans and coils can endure up to 20 years with regular maintenance.
How long should my AHU last after refurbishment?
Following an AHU refurbishment project that incorporates new dampers, coils, and fans the system’s lifespan can effectively be extended by 15 years. It's crucial to address any corrosion present on the AHU casework to enhance its longevity further.
However, regular maintenance still remains imperative to maximize the system's lifespan and ensure optimal performance throughout its extended service life.
HALO HVAC IoT sensors enables real-time monitoring for quick issue resolution, energy efficiency optimization, predictive maintenance, and remote control. Further future-proofing an AHU.
How often should I maintain my AHU?
Maintaining your AHU is essential for sustaining peak operational efficiency. While a general rule suggests maintenance every 6 months, the frequency may vary depending on specific applications and environmental conditions. In some cases, more frequent intervals might be necessary to uphold performance standards.
For a more data-driven approach, integrating wireless IoT sensors can revolutionize maintenance strategies. These sensors provide real-time insights, allowing for proactive maintenance based on actual system conditions rather than rigid bi-annual schedules. This dynamic approach ensures timely interventions, optimizing AHU performance and longevity while minimizing downtime.
HALO HVAC AHU Refurbishment Services;
EC Fan Upgrade
Switching to EC fan arrays enhances efficiency, resulting in significant energy and CO2 savings. These fans also provide redundancy in multi-fan setups and require easy maintenance without traditional components like belts and pulleys.
Filters & Air Treatment
Upgrading your filters and housings in line with ISO 16890 can significantly improve IAQ, system pressure drop, and energy consumption, reflecting a commitment to advanced technologies and overall system efficiency.
Coils
Replacing worn or damaged coils is essential for restoring optimal performance. Over time, changes in set point parameters may necessitate the installation of new coils that are heat pump ready.
Dampers
Replacing or repairing dampers and actuators in damaged areas ensures the restoration of airflow set-points while minimizing pressure drop.
