The ongoing COVID-19 pandemic has caused many facility managers to look into the cost of updating the heating, ventilation, and air conditioning (HVAC) system(s) in their buildings to improve air quality and keep them free from harmful particulates and pathogens.
An HVAC upgrade can be a worthwhile investment. Still, there are many variables in determining whether your organization can update its entire HVAC system or needs a new one. There is no one-size-fits-all solution to improving air quality in a building.
First, you need to determine if an HVAC update is worth the investment that will pay off in short-term and long-term energy efficiency and safer conditions. To help you out, we have put together a guide to help you determine the cost and benefits of updating your HVAC system.
There are many reasons for updating your facility’s HVAC system:
One solution is to add an HVAC induct with ActivePure technology for air purifiers. The technology is guaranteed to provide cleaner air throughout your building.
Let’s first look at the cost of a completely new HVAC system. Depending on existing ductwork, it will cost anywhere from $15,000 to $40,000 in 2021. Commercial buildings often require a larger HVAC unit, more ductwork, and thus, higher labor costs, so they are more expensive than similar residential units.
The cost of installation will depend on the complexity of the work and the cost of materials. For example, some HVAC installations require a crane, which could add to the final price.
Next, we’ll look at the cost of replacing parts of an HVAC system. The same factors apply when installing a new system, including the complexity of replacement, the amount of the existing system you are replacing, and the age of the system.
The average cost of installing replacement aluminum ductwork, insulation, ten vents, and two returns is $4,000 per 300 linear feet. However, you can expect to pay as much as $12,000 for the same amount of ductwork retrofitted for an existing building.
Using these numbers, you can estimate the cost of ductwork based on the square footage in your facility.
The cost of an upgraded HVAC system will depend on many factors, including the reason for the upgrade and system age. In general, however, you can expect an HVAC update will cost less than a replacement or brand-new system.
Here are some average costs for upgrades:
Another way to look at it is through the cost per update based on the type of building:
It’s essential to consider every aspect of your building when costing out an HVAC upgrade to get an accurate estimate. Here are some things that will figure into the cost:
Also, note that your HVAC system will need plumbing, and these costs are not included above.
When researching HVAC upgrades or trying to convince your CFO not to push the HVAC upgrade off for another year, you need to assess the life cycle costs associated with energy efficiency to determine the worth of the upgrade.
To do so, compare the cost of each HVAC part operating under “standard-efficiency” and “high efficiency.” Create a checklist and come up with your estimated lifecycle comparison costs for each element.
When you determine the cost of each life cycle scenario, it will become easier to justify the expense.
As you research updating an HVAC system, take time to document the reasons you need the update (see earlier examples) to present to your CFO.
Your CFO needs to know the actual cost and financial benefits of the update instead of a vague estimate based on a Google search. Provide them with a clear executive summary to help them understand all the variables, costs, and benefits.
As you begin to research options, reach out to local HVAC contractors to get estimates. Since estimates can vary by thousands of dollars, it is critical to acquire several for comparison.
Try to identify the cost-benefit ratio of each estimate based on the work to be done. You will want to break down each assessment into parts, labor, and contingencies—15–25% for unforeseen expenses and time delays. Also, show how other changes to the building or operations could impact the HVAC upgrade benefits and timeline.
Your analysis should include HVAC zoning, comfort, and future flexibility. For example, if energy efficiency is a top priority, you could also include government grants and rebates.
By taking these steps, you can present accurate upfront costs to your CFO. If you want to improve air quality, include potential savings from improved personnel productivity and health. For instance, as far back as 2002, one study determined annual productivity loss in the United States from sick building syndrome was $50–100 million, with $5–75 billion potentially preventable.
In addition, you should be able to demonstrate energy savings and real estate and operational expense savings for both the short and long term.
Finally, always present a plan B—especially if you need the upgrade for air purification. While not ideal, gradual improvements are always better than no improvement at all, especially when it comes to the health and safety of your employees and the public.
