How Do Heaters Work?

Your central HVAC system is capable of cooling and heating your home. While you may have your air conditioning turned up all summer long, there may be some chilly days during the winter when you decide to turn on the heat. To keep your HVAC system in peak operating condition, it is helpful to understand the science behind how your heater operates. Let’s take a closer look at how heaters work.

Electricity produces heat.

The power of electricity is behind the basic function of a standard heater. When electricity passes through a resistor, the unit will naturally grow hotter. While your home’s electrical components, such as its wires and circuits, must be protected from heat, your heating system actually harnesses electricity’s natural heating capabilities to heat up your home.

Heating elements channel electricity.

Your home’s heating system is equipped with a device called a heating element. When electrical current passes through the heating element, its coils will start to heat up. Heating elements are able to get hot enough to produce heat for an entire home or commercial space. While central HVAC systems have large heating elements, smaller heating elements can be found in common household appliances, such as toasters and hair dryers.

Ductwork channels heat around the home.

In order to heat up your indoor spaces, your heater needs to be connected to a series of ducts. As heat is produced by the heating element, fans blow the hot air into the ducts. Depending on the temperature setting of your thermostat, your heating system will deliver more or less hot air to the indoor spaces around your home.

Our company repairs air conditioners in Tucson, and we can make sure that your HVAC system is functioning properly throughout every season of the year.

What Are the Uses of Cryogenic Technology?

The term cryogenics is used to describe the way that sub freezing temperatures affect the characteristics of metals, gases, and other substances. If you work in the medical or engineering fields, chances are that you may use cryogenic refrigeration for one or more purposes in your work. Cryogenic technology, in fact, has many different applications across many industries. Let’s take a look at how cryogenic technology is used today.  

Nuclear Magnetic Resonance Spectroscopy

Today’s scientists use cryogenic spectrometers to evaluate the behavior and characteristics of elements on an atomic level. When cryogenically frozen magnets are placed in a NMR spectrometer, they will dramatically affect the magnetic fields of nearby atoms. By using superconductors that are equipped with cryogenic technology, scientists are making amazing discoveries about the world that we live in.

Magnetic Resonance Imagery

If you have ever visited the doctor for an MRI scan, you can thank cryogenic technology for your results. During an MRI, cryogenically frozen magnets are used to create detailed images of certain parts of the human body. These magnets are located deep within the imaging system of the MRI machine. Cryogenic technology has advanced modern medicine by allowing doctors to get a glimpse of the insides of their patients.

Frozen Food

Cryogenic technology also has uses that are completely unrelated to the scientific or medical fields. One of the most common applications of cryogenic technology is in the preparation of frozen food for transport. Using cryogenic technology, food processing plants can put large amounts of frozen food into a deep freeze. Cryogenic freezing allows companies to ship their frozen goods across long distances, all over the world.

See What Equipment Your Catering Business Needs

During the summer wedding season, your catering business may receive many new clients and work opportunities. To ensure that you are ready to provide your customers with quality catering services, you will need to equip your business with a full range of serving and food preparation equipment. Along with quality refrigeration, there are a few other items that every great caterer will need. Let’s take a look at what equipment is essential for your catering business.

Cooking and Serving Equipment

As a caterer, you will be preparing dishes that serve dozens or even hundreds of guests at a single time. Before you start your catering business, you will need to invest in restaurant grade cooking and serving equipment. Along with purchasing pots and pans, you may also want to invest in elegant buffet-style servers and attractive display trays for your delicious items.

Proper Transportation

One of the hallmarks of a catering business is that it is constantly on the go. When you work in the catering industry, your clients may expect you to arrive at the venue with all of your dishes fully prepped and ready to go. To bring your catered items to each venue throughout the work week, it will be necessary to invest in a large van or commercial vehicle with plenty of storage space.

Commercial Refrigeration

A catering business will typically use fresh ingredients that are of the highest possible quality. From fresh produce to delicious cakes and more, you may have many food items that need to stay under refrigeration until they are served. A commercial refrigeration unit will provide you with plenty of space to store all of your perishable ingredients.

If you are seeking commercial refrigeration for your catering business in Tucson, look no further than B&J Refrigeration. Our company provides refrigeration services to restaurants and catering companies throughout the local area, and we can help you find a solution that meets the needs of your business.

What Are the Essentials for Your Restaurant Kitchen?

Opening a new restaurant requires careful planning and preparation. Along with making sure that your dining area is comfortable and beautifully decorated, you will also need to build a functional and efficient kitchen space. A company that offers commercial refrigeration can provide you with the refrigeration that you need to keep your fresh items cold. Read on for an overview of some of the essential appliances that you will want to include in your restaurant kitchen.


Much of your kitchen’s meal preparation will be accomplished using a powerful range. Unlike the range that you may use at home, your commercial kitchen range will be equipped with many large burners and other professional-grade features. Depending on the preferences of your chef, you may want to invest in a high quality gas range for your kitchen space. A commercial range can also be equipped with special features, such as a grill or fryer unit.


An oven is another essential piece of equipment for any commercial kitchen. Your oven can be used to prepare baked dishes, and it may also be handy for heating up meals before they are served to your guests. If your restaurant will be offering fresh bread, pizza, and other baked goods, it might be necessary to purchase a bread oven that can heat up to high temperatures.


Proper refrigeration is critical for any commercial kitchen. Due to the high volume of food that your kitchen will be processing on a given day, it may be necessary to purchase a large, walk-in refrigeration unit for your restaurant. Purchasing a top quality refrigeration unit will boost the efficiency of your kitchen, and can also help to cut back on food waste.

If you are shopping for a refrigerator for use in your commercial kitchen, contact the experts at B&J Refrigeration. Our company specializes in commercial refrigeration near Tucson, and we offer a variety of walk-in refrigerator and freezer models.

Summer Is Almost Here: Is Your AC Ready?

In the Tucson heat, you won’t want to have to get through the summer without air conditioning. If you haven’t touched your air conditioner since last season, it’s a good idea to test it out before the weather gets too warm. Then you can take care of any necessary maintenance and repairs, and enjoy your unit for the rest of the year. Continue reading to see if your AC is ready for action.

Testing It Out Early

Unless you’re okay with being stuck without an air conditioner for days or even weeks of the summer, you should make sure yours is working before it becomes a dire necessity. The summer is the busy season for air conditioner services, so you don’t want to end up on a long line when you find out that your air conditioner isn’t working the way it did last year. The sooner you test out your unit, the more time you’ll have to see if it’s still in shape.

Performing Maintenance

When you turn on your air conditioner, one of the first things you should do is perform some basic maintenance. Change over your air filters to keep debris out of the system, and clear out any debris that might be crowding your outdoor condenser. You can also have your air conditioning maintenance professional tune up your unit to make sure it’s ready.

Handling Repairs

Sometimes your air conditioner won’t be in ideal shape when you start using it again. If this is the case, you should consult your air conditioner expert to see if there are any repairs to be done, or if you should replace your unit entirely.

If you’re not sure if your AC is ready for the warmer months, call B&J Refrigeration at (520) 308-6722. We are an air conditioning service in Tucson that would be glad to help you make sure your AC is in top shape. Visit our website or come by the office to learn more about us.

How Summer Thunderstorms Can Affect Your Air Conditioner

Summer thunderstorms can be fun to watch if you don’t mind thunder and lightning, but they might not be great for your air conditioner. There are different types of summer storms, and some are more dangerous than others for your unit. Read on to find out what you can do and who can help when a thunderstorm affects your AC.

Types of Storm Damage

The summertime tends to bring around more storms, but they’re not always the same kinds of storms. While you shouldn’t run into any problems when you use your air conditioner during a rainstorm, a thunderstorm may be a different story. Thunderstorms tend to come with lightning, which can affect the electricity in your house. If you have your air conditioner plugged in and turned on during a thunderstorm and lightning strikes your home or nearby power line, you could end up frying your unit.

What to Do with Your Unit

Some people think that their air conditioners will be fine during a thunderstorm because they have surge protectors, but this is not necessarily the case. A lightning strike can happen too quickly for your surge protector to catch up, so it’s best to keep your air conditioner unplugged until the storm passes.

Who to Talk to About Repairs

If your air conditioner does become damaged as a result of a thunderstorm, you should know where to turn. Your air conditioning professional can come over and look at your unit to see if it’s fully totaled or worth repairing. It’s a good idea talk to your repair professional sooner rather than later, so you can stay comfortable through the rest of the summer.

As a professional air conditioning service in Tucson, we can assess the damage and help you figure out what to do next. Call us at (520) 308-6722 for more information.


Choosing an Ice Machine for Your Restaurant

Whether you operate a fast dining establishment with counter service or an exclusive five-star bistro, you will find that ice is essential for daily operations. As you select an ice machine to suit your commercial refrigeration needs, you should answer a few questions that can point you to the right type of machine for your business. Read on to see what you need to know to choose the best ice machine for your restaurant.

Who will access the machine?

Do you prefer to allow customers to fill their own cups with ice and soda, or would you rather have your employees access ice beneath the counter? Knowing the answer to this question can help you narrow down your choices to an appropriate model, whether that is a countertop ice maker, a modular ice machine, or an under-counter ice maker.

How much ice do you need?

Capacity is another important spec when you are looking at new ice machines. Most under-counter ice machines top out at 350 lbs. of ice per day, so you might need to upgrade to a standalone modular machine if you have a higher demand for ice. Along with capacity, you should consider the cooling mechanism as well, since this can influence the capacity of your ice machine, especially in warmer climates.

What type of ice suits your restaurant?

You won’t want to overlook the end result when you are in the market for ice machines. Consider the different types of ice that each machine can produce so that you select the right one. Cube ice is most common, but you might need crushed ice if you have a salad bar setup or frequently produce blended drinks.

By calling on B&J Refrigeration for commercial ice makers, HVAC services, and walk-in refrigerators, you can rest assured that you will have a full range of choices with the expertise you need to select the right options. To contact us for commercial refrigeration services in Tucson, call (520) 308-6722.

Don’t Believe These Myths About Your HVAC System

In order to seek the proper heating and air conditioning service in Tucson, you should know what to believe and what not to believe. There are some myths out there about air filters, thermostat placement, and overall maintenance that you should debunk sooner rather than later. Continue reading to get to know the common myths about residential HVAC systems.

Your Air Filters Are Fine

A reputable heating and air conditioning service will never tell you that you can leave your air filters alone, as the opposite is true. It’s important for your energy efficiency and the working lives of your HVAC appliances to clean or replace your air filters on a regular basis. If you wait too long, the filters will become saturated with dirt and debris, forcing your HVAC units to work harder than they should.

It Doesn’t Matter Where Your Thermostat Is

The location of your thermostat is important, and anyone who tells you otherwise is misinformed. The thermostat analyzes the air surrounding it to determine whether your furnace or air conditioner should turn on or off. This means that if you keep your thermostat near a window that lets in plenty of sunshine, the heat from the sun could affect the reading on your unit and the functioning of your HVAC systems.

You Don’t Need Maintenance

Regular maintenance is crucial if you want your HVAC systems to stay in top shape. Even if nothing seems wrong, you need to stay on top of your heating and cooling appliances to make sure everything stays in working order. You can also set up a service plan with your HVAC professional and stick to a firm schedule.

Are you having trouble separating the myths from the truth regarding your HVAC system? Contact B & J Refrigeration or visit our website. We are an air conditioning service in Tucson that specializes in commercial refrigeration and HVAC services. Call us at (520) 308-6722 to find out how we can help.

Signs You Need to Repair or Replace Your AC

An air conditioner is a vital piece of equipment during the sweltering summer months. If you live in Tucson and you are concerned that your air conditioning system may be on its way out, now is a terrific time to contact your air conditioning service professionals. With professional services, you can learn whether your AC need to be replaced in the coming months. Here is a closer look at some signs that you need to repair or replace your AC system.

Ineffective Cooling

One of the top signs that your AC system needs to be repaired or replaced is when it is no longer able to cool your home or commercial building. An AC unit that is functioning properly will send a steady amount of cool air to every room or area of your property. Many times, ineffective cooling is the first sign that an AC system is about to go out.

Excess Moisture

In order to determine whether your air conditioner needs to be replaced, your technician may take a look at the condition of your outdoor condenser unit. A properly functioning condenser will have the ability to cool down your home’s air, without creating excess moisture or condensation. Condensation around the base of your condenser is a warning sign that you need a new system.

Unusual Noises

Your AC unit may also tell you when it is in need of a replacement. When a fully functional air conditioner is in operation, it will run smoothly and quietly. Clanks, bangs, rattles, and squeals could all indicate that your air conditioner is about to die.
