Zelka: Serving All Your Commercial HVAC & Refrigeration Needs

HVAC Preventive Maintenance

Big box store managers inevitably face crises. Here's one: multiple air conditioner units fail while temperatures outside flirt with 100 degrees—and soon it will be 80 inside and customer-filled isles will quickly empty. Are you prepared? Enter Zelka. We shoulder the often complex burden of accurately evaluating the problem, researching the model and serial numbers to order the correct parts and installing them promptly, all ensuring the store's climate keeps customers comfortable to maintain sales. Zelka's staff consists of former facility managers and employees at large national retailers, so we've encountered these emergency situations first-hand. We've since worked with many store managers confronted by urgent situations and understand their needs. Add to this experience our peerless data collection program, along with a close working relationships with our distributors, and we've developed the ability to seamlessly turn a problem into a solution with minimal impact to customers, associates and store sales.

HVAC COMMERCIAL

Zelka excels at HVAC commercial equipment installations, maintenance and repairs, with expertise in rooftop units up to 20-tons for national big-box retailers. We additionally offer thorough whole-building energy management and preventive maintenance services with routine seasonal inspections.

Ensuring HVAC Equipment Is Optimized

Zelka provides a superior preventive maintenance program with a proven record of reducing or eliminating emergency service calls and breakdowns through peak seasons. We foresee these issues and proactively correct them thanks to our thorough biannual unit and equipment inspections backed by our unparalleled data collection program. Each spring, we check air conditioner and dehumidification units and ventilation equipment to keep customers comfortable and products fresh, and to control humidity to keep pesky condensation from fogging glass case doors that obstruct shoppers from seeing merchandise. Come fall, our technicians perform comparable checks for heating units, including hanging radiant heaters in store vestibules, garden centers and other areas where cold air typically creeps indoors. With each seasonal inspection, Zelka starts every unit and checks all belts, blowers, exhaust fans, compressors and condensers to ensure all function optimally to minimize or eliminate failures. Zelka can service and install building control systems for both HVAC and refrigeration. Among these services are LED light controls that feature a system to calibrate dimming in relation to sunlight through windows and sunroofs, and dehumidification units to maintain proper dew points to reduce case condensation and ensure product freshness and quality. Moreover, when a store is crow cvded with shoppers, our CO2 system that monitors carbon dioxide levels opens dampers to force fresh air throughout the building, just as changing temperatures activate our unit sensors. Zelka works 24/7 to keep these and related systems running seamlessly in peak operating condition.

Refrigeration

Zelka has 25+ years experience installing refrigeration for new and existing stores and supermarkets with units ranging from single-case replacements to full-store remodels. From our multi-state locations, we can perform construction for installations with complete confidence in our expert craftsmanship. Our technicians also have training in and knowledge of energy-efficient refrigerants that include the upcoming CO2 Glycol Systems in industrial supermarket applications.

Refrigeration Services

At Zelka, we know firsthand what store managers face when systems fail because evaporator fans stop spinning, drains clog and coils freeze causing empty cases, flooded floors and foggy glass case doors. In retail, time is of the essence. Because we've worked in refrigeration service since 2000, our wealth of knowledge and vast database enable us to get equipment up and running quickly, translating to reduced time on service calls and cutting costs for our clients. We can service everything from standard reach-in cases to 60 x 30 walk-in dairy coolers, as well as refrigeration equipment in geographical areas from higher-risk and maintenance-heavy Florida to the colder climes of the Northeast. Zelka works primarily with Hill Phoenix, Kysor Warren and Hussman refrigeration systems to satisfy our customers' needs and ensure full cases, dry floors and clear glass doors.

REFRIGERATION INSTALLATIONS

Zelka also knows that many commercial clients have specific refrigeration needs and designs, whether bulk cases for beer or island or gourmet cases for sushi. We can accommodate them all. Our technicians have experience working with a wide-range of equipment, from one-ton self-contained units for convenience stores up to multiple parallel rack systems for the supermarket industry.

Peerless Preventive Maintenance Data Collection

More than a decade ago, Zelka technicians started to collect model and serial numbers and similar information on every piece of equipment—including all rooftop air conditioner units and their parts—in each store serviced. We designed a database that logs all this information to develop our preventive maintenance program. Today, we have an incomparable program cataloging extensive information on units, equipment and parts for as many as 300 stores. We are able to utilize this data with our reliable distributors, who can tell us everything about the equipment, from the year it was built to all the parts within, including the warranty status. This program has empowered us to forecast potential problems, predicting where and when a rooftop unit or a dehumidification unit is likely to fail—all adding up to our clients pocketing more dollars.

WARRANTY TRACKING

Zelka's data collection provides benefits across our various programs, especially for warranties. Did you know that if your store has a rooftop air conditioner unit, you typically have a compressor with a five-year warranty and a condenser with a 15-year warranty? If not, you're not alone--many store managers are unaware of their equipment under warranty. Our meticulous database allows us to track the lifespan of equipment for warranty purposes for unit replacement. This means Zelka technicians can know if a motor in a certain unit was changed three, five or 10 years ago—that is, what's new, what's old and what's likely to fail.
