Your store never sleeps, and neither do we. Our national dispatch center is staffed around the clock to triage calls, mobilize on‑call technicians and coordinate parts deliveries for emergency repairs. We stage night‑time installations to avoid disrupting shoppers and get you back to business fast.

Beyond rack systems, we handle split systems, rooftop units, makeup‑air and ventilation. Need a retrofit? We’ve navigated every refrigerant rule from the EPA’s SNAP program to the AIM Act. That means choosing the right low‑GWP blend—often R‑448A or R‑449A—and planning transitions well before deadlines. We design and install VFD retrofits, EC motors, head‑pressure controls and heat‑recovery loops to slash kWh consumption. Got a legacy R‑22 system? We’ll model whether conversion, replacement or CO₂ adoption makes the most sense, then handle recovery, evacuation and charge under EPA Section 608 guidelines.

HDS’s secret weapon is its people. In a market where skilled refrigeration techs are scarce, we maintain a close‑knit crew of licensed mechanics. Every vendor must pass a strict check‑in process covering insurance, certifications, background and adherence to HDS safety protocols, so you’re never opening your back door to an unknown contractor. We’ll work with your preferred vendors or tap our vetted partners—either way you get consistent reporting, uniformed technicians and full compliance with food‑safety and work‑rule regulations.

We cover all refrigeration equipment—racks, walk‑ins, prep coolers, server rooms, even motor rooms. Our SOP‑driven program uses a detailed checklist to inspect fan motors, evaporator coils, oil levels, contactors and sensors, and we customize condenser‑wash schedules based on region, ambient load and store conditions. The goal is simple: spot issues before they become outages, maintain compliance with EPA leak‑rate rules, and keep product cold and safe.
