The coil fouls itself, on schedule
Cottonwood in spring. Insects in summer. Leaves and construction dust in fall. Every season pushes a new layer of debris deep into the coil fins, where airflow can't shake it loose and a garden hose can't reach it.
Patented condenser-coil filtration · Chicago, USA
Coil Curtain is a patented honeycomb wrap that catches cottonwood, insects, and debris before they ever reach your coils — so they run factory-clean for five years straight. No pressure washing. No chemicals. No coil-cleaning line item.
The problem
Cottonwood in spring. Insects in summer. Leaves and construction dust in fall. Every season pushes a new layer of debris deep into the coil fins, where airflow can't shake it loose and a garden hose can't reach it.
A fouled condenser coil makes the compressor work harder for every degree of cooling. The energy penalty shows up on the utility bill, not the maintenance report — which is why it hides for years.
Quarterly coil cleanings buy you a few clean weeks, then the cycle restarts. Each visit costs labor, thousands of gallons of water, and harsh chemicals that end up in the runoff.

How it works
Coil Curtain is an engineered fibrous honeycomb, custom-fit to your unit on site. Its open cells are tuned to a simple threshold: air and fine particles pass through; the debris that fouls coils doesn't. What gets caught stays on the surface, where wind and gravity shed it — instead of packed into your fins.
Heavy debris rests on the curtain face — shed by wind and gravity, or brushed off in seconds. The fins behind it stay factory-clean, and air keeps flowing at full capacity.
Debris drives deep into the fin pack where no hose reaches. Airflow drops, head pressure climbs, and the compressor pays for it every hour it runs — until the next cleaning restarts the cycle.
Every curtain is cut and fitted to your exact unit — rooftop package units, MAUs, chillers, cooling towers. 100% customized, installed without downtime.
The honeycomb media covers the condenser's air intake — a physical barrier that also shields fins from hail and mechanical damage.
Open cells keep airflow essentially unrestricted while cottonwood, insects, and windblown debris stop at the surface.
No cleaning, no maintenance in between. At the end of its cycle, we replace the curtain — Home Depot is on its 4th.

Estimates use Coil Curtain's documented range: 20–40% cooling-energy savings per unit and planned coil maintenance reduced ~75% (Home Depot went from quarterly cleanings to annual inspections). Your site survey pins down the real number.
Proof at scale
The Home Depot didn't run a pilot and quietly drop it. They put Coil Curtain on every rooftop unit at every location — and have replaced it on schedule, cycle after cycle, for thirteen years. That's what a product looks like when the math keeps working.
One partnership. Four curtain cycles. Zero coil cleanings.
Cooling is the biggest non-IT load in the building. A fouled condenser quietly erodes PUE every hour of every day — Coil Curtain keeps rejection capacity at nameplate without adding a maintenance cycle.
Refrigeration runs 24/7; coil efficiency is margin.
The Home Depot playbook, ready for any fleet of rooftops.
Uptime-critical cooling with fewer contractor visits.
Protection that travels with the unit, including hail.
Small sites, big fleets — savings that multiply by location.
Sustainability
Coil cleaning is a water-and-chemicals habit your building repeats forever. Coil Curtain doesn't make it greener — it deletes it, and cuts the cooling energy on top.
Your site's green ledger
At 12 units, that's 64,800–129,600 gallons of water kept out of the storm drain every year — about 16–32 backyard pools over one 5-year installation. Chemical runoff: none. Put it in the ESG report.
Family owned since 2010
Coil Curtain was founded in Chicago on one stubborn idea: stop cleaning coils and start protecting them. Today the founder's daughter leads the company, the product is on its fourth generation of installs, and every curtain is still measured, cut, and fitted to the unit it protects — anywhere in the country.
