Refrigeration 101: 


Refrigerators, coolers and walk-in freezers are the most integral pieces of a grocery store or restaurant’s equipment. They are what preserve your food and ultimately allow you to function in an efficient way, day-in and day-out. We at Alpine Heating & Cooling can Service any type of unit listed below and get you back up and running with one simple phone call or email!


Commercial coolers or refrigerators are designed to maintain temperatures between 34°F and 40°F, while commercial restaurant freezers are required to maintain temperatures between -10°F and 0°F.


What do all of them have in common? Their ability to chill and preserve food, their compressor ventilation component and their outer stainless steel shell. Here are some of the types of refrigeration your restaurant should explore.


Below is a cheat sheet along with some descriptions of various types of refrigeration you can choose from:

Reach-In Coolers/Refrigerators and Freezers


Reach-In Refrigerator

Reach-in coolers and freezers stand upright, and often have multiple sections for maximum storage. Their storage capacity is determined by the cubic feet of the equipment. It’s best to keep these units toward the back of the kitchen, where there performance is best away from the heated line of cooking. This is an important thing to be aware of if you want to keep your stored food at a safe holding temperature.


Walk-In Coolers/Refrigerators and Freezers

Walk-in coolers and freezers are a wonderful option for restaurants where a large amount of space is required for cold storage. Some walk-in units are as small as a closet, while others are as large as an entire room. Your walk-in refrigerator or freezer should include shelving for maximum storage and organization. It’s a great space to store boxed items like produce, and any other items that take up a fair amount of space and are perishable.


Undercounter Refrigeration Drawers

Commonly referred to as fish-drawers, restaurant refrigeration drawers are used to hold seafood, meat and poultry. They are a wonderful space saving way to bring refrigeration right to the hot line of action while avoiding the cluttered space issues a reach-in would pose in that area.


Refrigerated Prep Tables

Refrigerated prep tables typically come in two configurations–sandwich/salad tables and pizza prep tables. The biggest difference between the two is the depth of the cutting board.


They are designed to use directly in the cooking line or preparation area, and keep food pans fresh and cold with their cold rails (or the cold storage wells). The drawers below the counter provide additional cold storage for a number of traditional items.


Merchandising Units / Display Refrigerators

Merchandising refrigeration units are designed to openly display foods or beverages with through the glass front door. These are great pieces of equipment for restaurants that offer self-serve or take-out menu items such as certain restaurants, delis and bakeries.


It also offers the opportunity to show your customers a scrumptious selection of your menu offerings on the front floor.

Restaurant Bar Refrigeration

Bar refrigeration units typically come in two sizes:

-Low boys, that are lower to the ground

- High boys, which rise to waist-level

Bar refrigeration units usually come in either a stainless steel exterior of black vinyl finish. Stainless steel finishes are more expensive than black vinyl, but are also less likely to dent and will also be the more durable option in the long run.

If you’ve heard people talking about “new refrigerant rules” for air conditioners and heat pumps, you’re not alone. Homeowners are wondering if their current AC system is suddenly outdated or impossible to repair. The simple answer is no — you do not need to replace your air conditioner just because refrigerant rules have changed. What Changed With HVAC Refrigerants? The HVAC industry is moving away from higher-GWP refrigerants, including R-410A, and toward newer refrigerants with lower environmental impact. Under the EPA’s refrigerant transition rules, many new residential air conditioners and heat pumps manufactured after January 1, 2025 must use lower-GWP refrigerants. Existing systems can still be serviced, and parts used to repair existing systems are not subject to the same restrictions as new equipment. For homeowners, that means your current air conditioner or heat pump does not automatically need replaced. Can My Current AC Still Be Repaired? Yes. If your system uses R-410A, it can still be serviced. The bigger question is whether a repair makes financial sense. As older refrigerants become less common over time, certain repairs — especially refrigerant leak repairs — may become more expensive. That does not mean every older system should be replaced, but it does make the repair-versus-replace decision more important. When Should You Consider Replacing Your AC? You may want to consider replacement if: -Your system is over 10–15 years old -You are facing a major repair -Your AC has a refrigerant leak -Your energy bills keep climbing -Your home has uneven temperatures -Your system uses older equipment that is no longer under warranty If your system is newer, running well, and only needs a minor repair, replacement may not be necessary. Don’t Panic — Get Honest Advice The new refrigerant rules are a real change in the HVAC industry, but they should not be used to scare homeowners into replacing equipment before they need to. At Alpine Heating, Cooling, Plumbing & Refrigeration, we help homeowners understand their options clearly. Whether your system needs a simple repair, a refrigerant leak check, or a full replacement estimate, our goal is to give you honest information so you can make the best decision for your home.
