Protect Your Aging Equipment. Retrofit Your HVAC Systems with Heresite

corroded coils

So, you’ve got an aging HVAC system. As we see it, you have two options:

  1. Plan for a beefy investment for a full replacement, or
  2. Find a way to extend the life of your equipment


For coils in or around humidity, salty air, or aggressive cleaning chemicals, corrosion is often the real issue, not the mechanical performance of a unit. Heresite coatings offer a valuable solution. It’s a phenolic-based protective barrier that creates corrosion resistance for your current coils without the cost, downtime, or environmental impact of building new equipment from scratch.

Start by Checking Out Your Coils

Not every coil can be retrofitted, so start with an inspection and look for:

  • Structural integrity. Coating can’t fix a coil with leaks, cracks, or compromised tube walls. The base metal needs to be solid.
  • Accessibility. The coils need to be removable (or coatable in place, depending on the specific process) for proper surface preparation and cure.
  • Life left in the unit. Coating a coil attached to a compressor or blower motor that’s on its last leg doesn’t make economic sense.

 

Then compare the cost-benefit against a total replacement, considering coating costs, the extended service life, and the operational risk of keeping the equipment in place longer.

Get the Most Out of Your Aging System

Once your coils are coated, they’re protected from the environmental bullies that often bring on corrosion. This protection can make the difference between a coil lasting five more years instead of one.

Lightening Up on Capital Replacement Pressures

An HVAC replacement is expensive and disruptive. But when it comes to performance, sometimes it’s not urgent. Why is that? Because the compressor, controls, and ductwork may still be working well even as the coils are corroding.

Coating retrofits let you:

  • Put off large capital spending, offering a calmer budget cycle
  • Avoid costly downtime that comes with replacing full units
  • Reduce the number of units that need to compete for replacement funds in any given year

 

For facility managers juggling many units, this kind of targeted plan can help with budgeting, providing a more predictable maintenance schedule, and avoiding simultaneous failures.

Coating retrofits won’t save every coil, but for equipment that’s structurally sound and just losing the fight against corrosion, they offer a cost-effective way to buy time, protect performance, and keep capital dollars for the projects that need them most.
