Where 24/7 cooling drives the energy bill.
Healthcare, food retail, and hospitality sites run cooling continuously, and pay for it continuously. They're also the sites where a refrigerant retrofit pays back fastest. Same equipment, same thermostat.
A measured retrofit, replicated across the commercial cooling estate.
A window AC retrofitted from R-22 to HCR 4242 and measured before and after by a third-party auditor. Independent field measurement is underway; verified results will be published once cleared.
Same unit · Same thermostat · Independent auditor
Same product line. Three operating contexts.
The Eco Kold blends map to commercial cooling at three different duty points. Healthcare and hospitality run the AC continuously; retail runs case refrigeration continuously. The blends are picked per refrigerant, not per industry.
Hospitals · clinics · medical campuses
Hospital cooling is a continuous, mission-critical load: operating theatres, blood banks, sterilization rooms, recovery wards. R-22 still runs the older wings, R-410A the newer. HCR 4242 and HCR 4141 are retrofit-ready (minimal to no equipment changes) on the existing equipment.
Supermarkets · convenience · cold storage
Walk-in cold rooms, display cases, and rooftop AC. HCR 4040 retrofits R-404A low-temp systems, HCR 4141 retrofits the AC. The same retrofit reduces the refrigerant inventory subject to F-gas reporting requirements and the energy bill at the same time.
Hotels · resorts · restaurants
The cooling load on a hotel is a guest-experience load: the AC needs to be quiet and consistent. HCR 4141 retrofits run noticeably quieter than the R-410A baseline (lower system pressure, less compressor work). Energy reduction shows up directly on the operations P&L.
Retrofit-ready: minimal to no equipment changes. Certified install. Audit-grade documentation.
A commercial retrofit is more about scheduling than engineering. The technical work is recovery → vacuum → recharge by weight: the same procedure as any refrigerant service. The procurement and audit work is what's different. Hydrocarbon refrigerant (ASHRAE A3, flammable); install by a qualified technician.
Single-line quote, no equipment line items
You're buying refrigerant cylinders and certified install hours, not condensers, compressors, or controls. The total project cost is typically a fraction of an equipment-replacement capex line.
One weekend for a typical commercial install
Recovery of the existing refrigerant, vacuum, leak-test, recharge by weight, run-in. A typical commercial AC retrofit is a weekend job; a multi-cylinder cold storage estate can be staged over a few service windows without taking the site off-line.
Before/after measurement included
For sites that want documented numbers, we coordinate third-party measurement. The CSVs and reports become a procurement deliverable, useful for sustainability reporting and case-study publishing.
A commercial quote takes one business day.

How commercial retrofits work in practice: scheduling, certified install, audit documentation, and the case-study replication path.
Can hospitals retrofit AC systems to hydrocarbon refrigerants?
Yes. A hospital window-AC unit can be retrofitted from R-22 to HCR 4242. Independent field measurement is underway; verified results will be published once cleared. Hospital cooling is continuous, mission-critical, and a high-payback retrofit category in commercial cooling.
What refrigerant is best for supermarket cold storage?
For low-temp refrigeration on R-404A or R-507 systems, HCR 4040 is the drop-in replacement. It matches the pressure curve of legacy low-temp refrigerants and reduces both the refrigerant inventory subject to F-gas reporting and the daily energy bill. See the HCR 4040 product page.
How long does a commercial AC retrofit take?
A typical commercial AC retrofit is a weekend job: recovery, vacuum, leak-check, recharge by weight, and run-in. Multi-cylinder cold-storage estates can be staged over several service windows without taking the site off-line. Quotes include the project schedule for your specific equipment list.
Will my staff need training to handle hydrocarbon refrigerants?
Day-to-day operation is identical to your current system: no new operator training required. Installation and service must be performed by a certified hydrocarbon technician (the same certification required for R-290 propane systems). Eco Kold maintains a directory of certified installers and matches one to your region with every quote.
Can a single facility audit prove energy savings before scaling?
Yes. Eco Kold can coordinate a 24-hour comparative third-party audit on a single unit before approving an estate-wide retrofit. The audit produces a documentation package: CSVs, before/after report, refrigerant-substitution documentation.
Have a system running on R-22, R-410A, R-404A, or R-134a?
Send us the equipment make, model, and current refrigerant. We'll match the right Eco Kold blend, quote pricing, and connect you with a certified installer in your region, usually within one business day.
