In the world of building management, owners and Facilities Management (FM) partners are often confronted with a challenging decision: replacing or refurbishing HVAC systems.
Air conditioning, air handling units, and heat recovery systems, are essential to maintaining comfortable and safe environments. However, deciding whether to invest in replacing these systems or refurbishing HVAC systems is a dilemma many face. With the ever-increasing focus on sustainability energy efficiency, and cost-saving solutions including minimising downtime, refurbishing HVAC units has become a more viable option.
Why Refurbish HVAC Systems?
Facilities where proper HVAC maintenance is routinely conducted can experience a substantial reduction in energy consumption, with energy usage decreasing by as much as 15% to 20% (FacilitiesNet). For many building owners, refurbishing HVAC systems presents a strategic and cost-effective solution, offering a balance of improved performance and operational efficiency. Compared to full replacements, refurbishment provides significant advantages, such as lower expenses and enhanced system longevity, without sacrificing performance.
Reduced Downtime and Disruption
One of the primary concerns when replacing HVAC systems is the downtime and disruption it causes. Refurbishing, on the other hand, typically takes less time, and because units can be refurbished in phases, the building can continue to operate without significant interruptions.
For clients with multiple units in their HVAC systems, staggered refurbishments mean that there will always be functioning systems in place. Since the existing water, electricity, and duct services are often left untouched, the need for major alterations or rewiring is minimised. This makes refurbishment a less invasive option for building owners looking to upgrade their systems without major interruptions.
Other Refurbishment Benefits
Cost-Effective Solution
Refurbishing HVAC systems is often far more affordable than a complete replacement. This cost-saving approach allows building owners to work within their budgets while improving the performance of their HVAC units.
Improved Operational & Energy Efficiency
Refurbishing HVAC systems is not just about making the equipment look new; it’s about improving performance. Refurbished units run more efficiently, which can lead to a reduction in energy consumption. This not only contributes to sustainability efforts but also translates into lower energy bills, benefiting businesses in the long run.
Energy costs are a significant concern for many businesses. With energy prices now 50% higher than pre-Covid levels and a further 3% rise expected in April (BBC News), the increasing focus on efficiency makes HVAC systems essential for managing costs.
Increased Life Expectancy
Just like any machinery, HVAC systems will age over time. Refurbishing them helps increase the longevity of the equipment, ensuring that the system remains reliable and operational for many more years. With regular maintenance and careful upgrades, refurbished systems can continue to perform at optimal levels.
What Is the Life of a Commercial HVAC System?
The life expectancy of HVAC systems can vary depending on factors such as maintenance, usage, and environmental conditions. On average, a well-maintained system can last between 15 and 25 years. However, as systems age, their efficiency tends to decrease, leading to higher energy bills and more frequent repairs.
As mentioned above, refurbishing existing HVAC systems can help extend its life expectancy significantly, allowing businesses to continue benefiting from the system without the need for a full replacement. Regular maintenance, such as cleaning, changing filters, and replacing worn-out components, can also prolong the life of the system.
How Do You Tell if You Need a New HVAC System?
There are several signs that may indicate it’s time to replace your HVAC systems. Some of the most common signs include:
-
- Frequent Repairs: If you’re consistently calling for repairs or replacing components, it might be a sign that your system is nearing the end of its life and needs refurbishing.
-
- High Energy Bills: Older systems tend to be less energy-efficient, leading to higher operating costs. If your energy bills have increased significantly, it may be time to consider upgrading your HVAC systems.
-
- Poor Air Quality: HVAC systems that are not functioning properly can impact indoor air quality. If you notice an increase in dust, humidity, or unpleasant odours, it could be a sign of system failure.
-
- Uneven Cooling or Heating: If certain areas of the building are too hot or too cold, it might indicate a problem with the HVAC system’s ability to distribute air effectively.
-
- Age of the System: If your HVAC system is over 15 years old, it may be time to assess whether a purchasing a replacement or refurbishing is the best option.
