Recognizing Signs of Problems with Your HVAC

If you have problems with your HVAC system, the worst time to find out is when your AC goes out on the hottest day of the year. Fortunately, you can head off this unwelcome surprise by paying close attention to signs that trouble is brewing with your HVAC system. If you spot these signs, call your HVAC repair tech to have your system inspected and any necessary repairs made.

Musty Odors

When your AC kicks on, does the air start to smell musty? If you, so you could have a problem with moisture inside your system. In some cases, the musty smell may simply be from excess water, but in other instances, your system may have mold or mildew in the ducts. Not only will a moisture problem eventually lead to a system failure, but it could also cause mold to be carried in the air throughout your home, putting your family at risk.

Uneven Temperatures

Do some areas of your home feel cool and comfortable, while others feel hot and stuffy? These zones of uneven temperatures are usually the result of a problem with your HVAC system. In addition to uneven temperatures, pay attention to signs that your system is having a hard time moderating your home’s interior temperature. For example, you may notice that your home doesn’t feel as cool as normal, or you may note that your system is running constantly, trying to maintain the temperature. All of these issues are signs of trouble with your HVAC system.

Drainage Leaks

All HVAC systems have a drain line that should efficiently remove moisture from the system. However, the line could become clogged or rusty, which causes it to fail. When this happens, you may notice leaks from your system. Get your HVAC specialist to inspect and replace your line, if needed.

Don’t let HVAC malfunctions catch you off guard. When you spot any signs of trouble, call B&J Refrigerator for repair services. For more information or to schedule an appointment for HVAC service in Tucson, call (520) 308-6722.

What You Need to Know About Choosing a Lab Fridge

Selecting a new laboratory fridge is a far more delicate procedure than choosing a new fridge for a home kitchen. Lab samples must be stored within very tightly controlled temperature ranges to avoid compromising their integrity or viability. Because of this, labs must choose from cold storage options specifically designed and constructed for use in a lab setting.

Temperature Control

Perhaps the most important consideration when choosing a new lab fridge is the temperature control. These days, the most sophisticated options use microprocessor temperature controllers with digital LED displays. Some options allow for setting a temperature accurate to one decimal place.

Temperature Recording

Lab technicians following the recommended best practices will manually evaluate and record the temperature of the lab fridge twice daily. To reduce the need to open the door, and subsequently, cause temperature fluctuations, consider selecting a fridge that displays the internal temperature on the outside of the unit.

Temperature Alarm

Although automatic alarms don’t replace the need for twice-daily manual checks of the temperature, they can alert technicians to unexpected fluctuations. This is crucial when storing vaccines and pharmaceuticals, as a dip in temperature can affect the potency. High-end lab fridges integrate the temperature alarm system with remote alarm contacts, which will alert technicians elsewhere in the building to the temperature fluctuation at the lab fridge.

Fridge Defrost

Most lab technicians prefer to work with cold storage units that have an automatic defrost feature. These models tend to produce a more uniform internal temperature. For precision control, look for a unit that allows users to control the duration and frequency of the defrosting.

Special Considerations

Samples that are volatile or explosive require specialized refrigeration units. Explosion-proof fridges protect the lab employees, samples, and the environment. These generally feature a spark-free interior and exterior.

For all of your commercial refrigeration needs, you can count on B & J Refrigeration. We offer affordable new system installation and repair services in the Tucson area. Call us today at (520) 308-6722 to discuss getting a new lab fridge installed.

Building a Home? Here’s How to Pick the Right HVAC

There are so many choices when it comes to residential heating, ventilation, and air conditioning (HVAC) systems. To make sure you select the right system for your new home, it’s best to turn to an HVAC company for expert guidance. The HVAC technician will ensure you choose the right size and type of air conditioner, heat pump, or furnace to make your new home as comfortable and energy-efficient as possible.


Homeowners have more choices available to them than ever before. You could choose a heat pump, for example, which both heats and cools the home. You might prefer a central AC unit with ductwork. Or, you might be more interested in investing in a ductless mini split system, which allows for zoning control and doesn’t require the installation of ductwork.

Energy Efficiency

Energy efficiency is a top priority for many homeowners, especially in sunny Arizona where air conditioners get plenty of usage. Your HVAC technician will consider the size of your home, the insulation used, and the climate of the area to make recommendations regarding the most energy-efficient HVAC system for your home. Feel free to ask any questions you may have about energy efficiency ratings and labels.


Your family’s comfort is important, and your HVAC contractor can help you maintain it. Discuss your options for customizable zoning. For instance, you may want to be able to adjust the temperature within individual rooms, rather than on a floor-by-floor basis. This is particularly helpful for families with young children and for future parents who plan to grow their families. Consider noise as well as temperature. If you’re particularly sensitive to the typical noises that an average HVAC system makes, talk to the technician about quieter options.

At B & J Refrigeration, we’re known for our expertise in commercial refrigeration, but we also provide exceptional home heating and cooling services. If you’re building a new home in the Tucson area, give us a call at (520) 308-6722 to discuss your needs.

What You Need to Know About Electronic Air Cleaners

Does the air in your home feel or smell stuffy all the time, no matter how often you clean? Does someone in your family suffer from asthma or allergies, or display persistent respiratory symptoms? If so, it’s time to talk to an air conditioning company about having an electronic air cleaner installed in your home.

Why You Need an Electronic Air Cleaner

The air indoors can sometimes be more heavily contaminated than the air outdoors—even for city dwellers! In fact, indoor air pollution is considered to be among the most serious environmental health risks. The indoor air can be polluted by particulate matter, including the following:

  • Smoke
  • Dust
  • Pollen
  • Animal dander
  • Tobacco

Particulate matter includes tiny particles associated with bacteria, viruses, molds, and dust mites. Gaseous pollutants can also contaminate the indoor air. These are derived from combustion processes. Some common sources of gaseous pollutants include the following:

  • Paints
  • Adhesives
  • Gas cooking stoves
  • Vehicle exhaust
  • Varnishes
  • Cleaning products
  • Pesticides

These are just a few of the contaminants that could be clouding up the air in your home. By installing an electronic air cleaner in your home, your family can have a safe haven from these dangerous pollutants.

How Electronic Air Cleaners Work

Although there are some differences from brand to brand, electronic air cleaners generally rely on three mechanisms of action to scrub the indoor air clean. They are the use of physical filters, ionization, and ozone generators.

  • Physical filters: Air is pushed through a filter to remove large particles, such as lint and fur.
  • Ionization: The smaller particles pass through the filter and enter the ionization area, where they are charged so that they clump together. The plates inside the device use positive and negative charges to cause the small clumps of particles to stick to the plates.
  • Ozone generator: Air passed through here gets extra oxygen atoms, which combine with the contaminants to kill microorganisms.

Questions to Ask When You Choose an HVAC System

A heating, ventilation, and air conditioning system is one of the most important investments you’ll make for your home. Whether you’re replacing an old system or getting ready to move into a new construction house, it can be tough to make a final decision regarding the right HVAC system for your home. Your HVAC technician can answer all of your questions and provide expert recommendations.

How energy-efficient is this HVAC system?

Energy efficiency is a hot button issue in the heating and air conditioning industry. Plenty of homeowners rank environmental friendliness as a top priority, and everyone likes to save money. Both of these goals are attainable with an energy-efficient HVAC system. Your HVAC contractor can let you know what the SEER rating is for your chosen system, and whether it’s an ideal SEER rating for the climate in Arizona.

Is this HVAC system appropriately sized for my home?

HVAC technicians can calculate the right size of system for your home. This is a major consideration because, if your HVAC system is too small, it will run constantly and your home won’t reach the comfortable temperatures you desire. On the other hand, if your system is too large, it will run too infrequently to properly regulate the humidity levels inside your home. Neither of these situations is ideal.

Is a ductless mini split right for my home?

Ductless mini splits are very popular, particularly among homeowners who are interested in separating their homes into different heating and cooling zones. This allows you to more precisely control the temperature in any given room. As the name suggests, a ductless system doesn’t use ductwork. The hookup between the indoor, wall-mounted units and the outdoor unit requires only a very small hole in the wall.

Zoning Systems 101

There are many elements to consider when building a residential or commercial space. One of the most important is the HVAC system and whether you’ll include zoning systems. Keep reading to learn the basics of zoning systems and their benefits:

What is a zoning system?

A zoning system is one that separates parts of the home or commercial building into different zones. Each zone has its own thermostat so that different parts of the building can be heated or cooled as needed. The ductwork in zoning systems feature dampers that are electronically-controlled. These dampers are used to control the flow of hot and cold air that circulates throughout the house. Each zone’s thermostat can control the dampers in that area, telling them to open to allow more cool air in or close when the desired temperature has been reached.

What are the benefits of a zoning system?

Whether you’re building a home or commercial space, you should consider including a zoning system in your construction plans. These systems allow you to regulate the temperature in different parts of the building, instead of choosing one temperature for the whole space. A zoning system can be beneficial in multi-level buildings that might suffer from hot and cold spots. Each level will be part of its own zone, so temperature can be regulated level by level for optimum comfort. Zoning systems are also great choices in home with families who have different temperature preferences. If some members of the family prefer a warm home while others like it cooler, you can design the home to have different zones that will let each family member pick his or her desired temperature.


If you’re in need of a zoning system for your new construction project, you can contact B & J Refrigeration. Our Tucson refrigeration specialists can work with you during every phase of the project to make sure everything goes according to plan. Call us at (520) 308-6722 to get started.


Examining the Benefits of Home Humidifiers

Home humidifiers make it easier to regulate the level of moisture in the air inside of your home. How can you tell if this feature is right for your space? Keep reading to learn about the benefits of home humidifiers:

Using less energy and saving money

Humidifiers can help make your home feel warmer, which means you won’t need to rely as much on your heating system. You can use less energy during the colder months of the year when you invest in a home humidifier. Because of this, you’ll also save money on your utility bills!

Preserving materials in your home

There are many materials in your home, furniture, and accessories that can become damaged due to dry air. Items like wood floors and furnishings, walls, paint, and art can all become damaged, warped, and cracked when the air in a home is too dry. Other items, like electronics, can be damaged when there is too much moisture in the home. A home humidifier will help you maintain an appropriate level of moisture in your home, helping to preserve these and other materials.

Feeling more comfortable

Do you suffer from dry skin, allergies, or asthma? If you do, then dry air can make your symptoms even worse. You should feel totally comfortable when you’re at home, and a humidifier can help. With more moisture in the air, you won’t have to worry about symptoms being intensified by a dry environment.

Improving your health

Low-humidity environments can make it easier for viruses to spread. This means you might be more likely to catch a cold or the flu or develop respiratory issues if your home has low humidity levels. You can prevent this with a home humidifier. You’ll be able to breathe easier your home has the right levels of humidity!

SEER Ratings 101

When you’re choosing an air conditioner, one of the things that you are likely to check is the SEER rating. The SEER rating can tell you a lot about the efficiency of the air conditioner you’re considering, but does it tell you the whole story? Here is what you need to know about SEER ratings and how they should impact your air conditioner selection.

What exactly is a SEER rating?

SEER is short for Seasonal Energy Efficiency Ratio. Although many people associate SEER ratings with air conditioners, they are also listed on heat pumps as well. The SEER rating is determined by using an equation: cooling air output during a typical season divided by the amount of energy used by the system, also referred to as the energy input. This figure essentially says how much cool air is produced by an air conditioning system and how much energy it requires to produce it.

How can I tell if a SEER rating is good or bad?

The higher the SEER rating, the more efficiency an air conditioner is. Most states have minimum requirements for SEER ratings and don’t allow units rated below 13 or 14. Ratings go as high as 25 SEER. As technology advances, higher SEER ratings are likely.

Should I always buy the highest SEER available?

Because the cost of air conditioners increase with higher SEER ratings, you have to balance the cost of the unit with the savings you are likely to achieve on your energy bills. If you have an old air conditioner, then upgrading to even a 14 SEER unit can lead to significant savings. Keep in mind that SEER ratings represent the maximum efficiency of a unit and don’t mean that the air conditioner functions at that level at all times. Other factors can also impact your air conditioner’s efficiency.

Why HVAC Maintenance Is a Smart Investment

Replacing your HVAC system is a major expense, so it makes sense to try to make your current system last for as long as possible. The key to maximizing the longevity of your HVAC is having regular maintenance services. If you think you have been saving money by skipping regular maintenance, you could actually be making an extremely costly mistake. Here are some of the reasons that spending on HVAC maintenance is a start investment.

Longer Lifespan

Although many variables determine how long an HVAC lasts, from the quality of the system to how much use it gets, most systems last for about 15 to 20 years. However, without maintenance, the lifespan of your HVAC could be much shorter. During maintenance, your technician will ensure that all of the components of your HVAC are in good working order and make any necessary repairs, which will prevent small issues from turning into more complex problems that can ultimately cause you to need a new system.

Better Efficiency

When your HVAC is tuned up and working properly, it will work as efficiently as possible. Even a small issue can significantly reduce the efficiency of your system, causing it to work harder to maintain a comfortable temperature. Regular maintenance will ensure that your system is working efficiently, which will reduce your energy usage and help you save money on your utility bills.

Affordable Repairs

If a problem does occur with your HVAC, fixing it may be less expensive. When you have maintenance services, your tech can find problems before they even begin to cause any signs, so you can have them repairs as soon as possible. By catching the problems early, the repairs are usually less expensive.

Tips for Organizing Your Restaurant’s Walk-In Cooler

As businesses that work with perishable inventory, restaurants must follow a well-designed organizational system for their commercial refrigeration units. Good organization allows your restaurant employees to find needed items quickly, prevent food spoilage, reduce the risk of cross-contamination, and perform proper sanitation.

Storing Meat Products

Juices, marinades, and meat fragments can fall from stored meat products onto other foods. You can prevent cross-contamination by storing meat products on the lowest shelf. Keep all non-meat products away from meats. If any other food does come into contact with meat or its juices, you must throw away the contaminated food.

Storing Produce

Commercial refrigeration units like walk-in coolers have strong fans to maintain a safe air temperature for food storage. Because of the vigorousness of the air flow, it’s a good idea to store delicate produce items away from the fans to prevent the possibility of freezer burn. Fresh greens and berries are examples.

Organizing by Use-By Dates

Give yourself or your employees enough time to stock newly delivered food items. Taking a few extra minutes to organize new items can prevent food loss from spoilage. Check use-by dates on old and new items, and move things around as needed so that the items with a shorter shelf life are placed toward the front of the shelf. Items that will keep longer should be placed toward the back, and they should be used last.

Spacing Items

It might seem like packing everything as close together as possible would be an efficient use of your walk-in cooler space. But actually, the cold air needs to be able to circulate. Uneven cooling may lead to food spoilage. Leave about three to six inches of space between food items, and between the food and the walls.
