What Are the Advantages of a Ductless HVAC System?

Not every HVAC system needs ductwork to operate. It turns out that heating, ventilation, and air conditioning appliances that don’t use air ducts help you avoid certain problems. You save money, reduce your carbon footprint, and bring up your indoor air quality. Read on for more on the advantages of going ductless.

Save Money

Part of the problem with heaters and air conditioners that use air ducts is that they’re not optimally efficient. The less efficient your HVAC systems are, the more money you’ll pay in energy bills. Most people don’t even realize that their heating and cooling systems make up the bulk of their energy bills, so they don’t know that they could be saving a great deal of money. A ductless HVAC system is more efficient than one that uses air ducts because the air goes directly into the space without having to travel through a labyrinth of ductwork.

Protect the Environment

Saving energy means more than saving money—it also means saving the environment. A ductless HVAC system will make your space more comfortable with much smaller energy requirements than an HVAC system that uses ducts. Even the refrigerant used in ductless HVAC systems is more environmentally friendly. In addition, the added energy efficiency will allow your heating and cooling appliances to last longer, so you won’t have to replace them for a while.

Improve Indoor Air Quality

Air ducts tend to harbor dust, mold spores, and even pests. Then the air that circulates through the vents picks up contaminants and spreads them around the house. This isn’t an issue with ductless HVAC systems, so you can look forward to higher quality indoor air.

Learn the Terminology for Residential HVAC Systems

Not all the terminology involved with residential HVAC systems is known to the common person, so it helps to brush up on some key terms. You might not even know what the acronym “HVAC” itself even stands for. Read ahead and learn the terminology for residential HVAC systems.

HVAC

The acronym HVAC stands for heating, ventilation, and air conditioning. A contractor or business that specializes in HVAC should be prepared to service any appliance that contributes to the heating, cooling, or ventilation of your home, but some companies may specialize in one facet. If you ever have a problem with your HVAC systems, make sure you find a company that specializes in the specific aspect of HVAC appliances that you need help with. You should also make sure you’re working with a company that deals with residential HVAC systems, as commercial systems tend to be under a different pressure.

SEER

When you’re trying to determine how efficient an air conditioner is, you should look at its SEER rating. The seasonal energy efficiency ratio describes how effective the air conditioning unit will be throughout the season compared to how much energy it will consume. The more energy it consumes, the more money you spend and the shorter its lifespan will be. Try to find a unit with a high SEER rating so you can enjoy great HVAC efficiency for your home.

HSPF

SEER ratings indicate how successful an air conditioner will be, and HSPF ratings describe the performance of heaters during the winter. HSPF stands for heating seasonal performance factor, and a high rating means that your heater will keep you warm throughout the cold season without expending too much energy.

Don’t Believe These Refrigeration Myths

It always helps to get a second opinion, and the case is the same when it comes to myths about commercial refrigeration. Many people believe in myths that are simply not true, and they might end up getting sick because of them. Keep reading and don’t believe these refrigeration myths.

Bacteria won’t survive in the refrigerator.

You might think that you are safe from cross-contamination in the refrigerator because of the low temperature. However, this is not actually the case. Many kinds of bacteria can survive in the refrigerator, and some even grow in the cold conditions it creates. The good news is that you can prevent this contamination by separating your fruits and vegetables from your seafood, eggs, and raw meat. You should also clean up any spills that happen immediately, and use hot water and soap to clean your refrigerator’s walls and shelves.

I can tell if my fridge is cold enough.

No matter how sensitive to temperature you are, you’re never as qualified to tell how cold your fridge is as a thermometer. The temperature inside your refrigerator should never be more than 40 degrees Fahrenheit. Each fridge has a dial that you can use to adjust the temperature, so use a thermometer and make sure that yours is low enough to keep your food fresh.

Leaving food out is fine if you put it in the fridge later.

The most a refrigerator can do for your food is slow the growth of bacteria. It won’t kill bacteria that already exists, so you can’t leave your food out and then expect the bacteria to disappear once you put it in the refrigerator.

Myths about commercial refrigeration in Tucson can be tricky, but you shouldn’t fall for them. If you want to make sure your refrigeration systems are up to par, call B&J Refrigeration at (520) 308-6722 or check out our website to learn about our air conditioning services.

What Foods Can and Cannot Be Refrigerated?

Some foods need to be refrigerated to stay fresh and delicious, while others shouldn’t be put in the refrigerator at all. You need to know what should and shouldn’t be kept in your commercial refrigerator, or you might spoil your ingredients. Here’s an overview of some foods that can and cannot be refrigerated and why it matters.

Refrigerable Foods

It’s nice to know the rules of refrigeration so you can take care of your appliances and keep your food fresh. When it comes to foods that you should refrigerate, dairy products are on the list. Cheese, milk, and eggs should all be stored in the refrigerator to keep them fresh and reduce bacteria and mold growth. Butter can be refrigerated, but it’s up to your personal preference. Soy milk and condiments don’t need to be refrigerated until they’ve been opened.

Foods That Should Stay Out

You might be automatically inclined to throw any leftovers you want to save into your refrigerator, but this isn’t the best place for certain food products. For example, potatoes are not a good candidate for refrigeration due to the starches in them. Refrigeration will also ruin the consistency of honey and make your onions and tomatoes moldy. Hot sauce can stay out of the fridge as well, especially if you want to maximize the spicy heat.

The Importance of a Fridge

Refrigerators and freezers are both crucial for both residential and commercial food storage. You can’t run a commercial kitchen if you don’t have a way to preserve your ingredients, and you’ll waste ingredients if your fridge or freezer ends up breaking down. Upgrade your refrigeration whenever necessary, commit to a maintenance schedule, and call the professionals for speedy repairs.

How to Increase the Energy Efficiency of Your Refrigerator

More efficient commercial refrigeration helps you save money and protects the environment, and it can keep your refrigerator around longer. Don’t store things on top of your fridge or leave the door open when you take things out, and bump up the temperature if it’s unnecessarily cold. Read on for more on increasing your refrigerator’s efficiency.

Keep the Top Clear

You don’t want to experience heat loss in some appliances, but it can be helpful for your refrigerator. Some refrigerators emit heat from the top of the unit, which helps the interior stay cool without using as much energy. When you stack things on top of the refrigerator, this heat becomes trapped and the fridge must work harder to maintain a cool temperature. This brings your efficiency down and your energy bills up, so don’t put cereal boxes or containers on top of the fridge.

Don’t Leave the Door Open

It can be a pain to have to dig through the refrigerator to find what you’re looking for, and it wastes energy as well. Try to open and close the door quickly so the cool air stays in the fridge rather than dissipating out into the room. Close the refrigerator door as soon as you find the ingredients you need, and never walk away from the fridge with the door left open.

Increase the Temperature

Your refrigerator doesn’t have to be set at freezing cold temperatures to keep your food fresh. If you have some wiggle room, increase the temperature by a few degrees. This will be easier to maintain, and your fridge won’t sap as much energy or money.

Let the professionals at B&J Refrigeration help you make your commercial refrigeration in Tucson as efficient as it can be. Head to our website or call us directly at (520) 308-6722 if you have any questions about us.

Is Your Restaurant’s Equipment Ready for Snowbird Season?

As the summer season transitions into fall, many residents of Northern states will be making their way south. In Arizona, we often refer to the busy winter months as snowbird season. When seasonal residents come to Tucson, they will patronize restaurants and other local business. To help you make sure that your air conditioning and other pieces of equipment are ready for the busy months ahead, here is a look at some essential restaurant maintenance tips.

Service Your HVAC System

In Arizona, temperatures can remain toasty well into the fall season. As you are getting ready for increased business, you will want to make sure that your HVAC system is prepared to keep your dining area and kitchen at a comfortable temperature. Before the busy season really kicks into gear, consider setting up professional air conditioning services.

Inspect Your Refrigerator and Freezer

Proper refrigeration is essential for any business. If your refrigerator suddenly quits during a busy dinner service, your fresh and perishable items may spoil before they can be served to your guests. To make sure that your restaurant is ready for snowbird season, take the time to inspect the performance of your refrigeration unit. Any maintenance issues should be immediately addressed by a licensed technician.

Tune Up Your Cooking Equipment

Whether you cook on a range, griddle, or conventional stove, you need to make sure that all of your cooking equipment is ready to perform during the peak season ahead. A properly functioning range will allow you to prepare all of your signature dishes with ease. Since your cooking equipment receives considerable wear and tear, it should be maintained regularly.

When you are getting your restaurant ready for snowbird season, the team at B&J Refrigeration will be there to help you. Our Tucson company offers HVAC and commercial refrigeration services to many top restaurants in the area. To learn more about the services that we have to offer for your restaurant’s equipment, give us a call at (520) 308-6722.

Exploring the Benefits of Changing Your AC Filter

Air conditioning is a must-have for homes and businesses in Tucson. Without a properly functioning air conditioner, you will have no protection against the desert’s heat. One way to make sure that your air conditioning system remains in good working condition is to change your air filter at least once a month. Some of the terrific benefits of changing your AC filter include:

Extend Lifespan of Your System

One of the top reasons to make sure that you always change your air filter is that regular air filter changes will help to extend the lifespan of your system. When your AC’s air filter gets clogged, your unit will have to work even harder to cool down your home or building. Maintaining a clean air filter will reduce strain on your AC unit, which, in turn, will extend its lifespan.

Avoid Air Quality Issues

The main function of your AC’s air filter is to eliminate dirt, dust and other tiny particles that are hiding in your indoor air. If you go too long without changing your air filter, you will find that your building’s indoor air quality starts to deteriorate. To keep your indoor air healthy and fresh, take the time to switch out your filter once a month.

Ensure Efficient Performance

Paying for air conditioning can be a considerable expense for any household or company. To cut down on your energy bills each month, schedule AC filter changes at regular intervals. When your air filter has been freshly changed, your air conditioning unit will function as efficiently as possible.

Learn the Importance of SEER Ratings

When you are shopping for a new air conditioning system for your home or commercial property, you will need to compare the specifications of several different units. One of the most essential factors to consider as you are selecting an air conditioner is the unit’s SEER rating. A unit’s SEER rating, which stand for Seasonal Energy Efficiency Ratio, will tell you a great deal about its efficiency and overall effectiveness. Read on for an overview of why SEER ratings are so important.

SEER ratings determine energy consumption.

As you are comparing SEER ratings of different air conditioning systems, it is helpful to understand what the SEER rating is actually telling you about the unit. SEER ratings are calculated based on a unit’s consumption of energy. A unit that is very energy efficient may have a SEER rating of 20 or more.

SEER ratings can result in cost savings.

If you want to save as much money as possible on your monthly air conditioning bills, you will want to purchase an air conditioner that boasts a high SEER rating. Air conditioners that are more efficient will consume less energy throughout the course of a day. When you invest in a system that has a high SEER rating, you may start to notice that your energy bills drop, even during the hottest months of the year.

SEER ratings may change after installation.

SEER ratings are essential because they demonstrate the projected energy efficiency of an air conditioning system. You should note, however, that your system’s SEER rating may change after the installation process is finished. To achieve the best SEER rating from your air conditioner, you will need to make sure that your unit is properly insulated.

For additional information about SEER ratings and air conditioning services, contact B&J Refrigeration by calling (520) 308-6722. We proudly offer commercial refrigeration and air conditioning services in Tucson, and our experienced team members can help you purchase the right air conditioning unit for your property.

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.

For answers to your questions about how your heater or air conditioner works, contact the team at B&J Refrigeration. 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.
