The Latest with Apex

What do trade schools offer that a four-year university or two-year community college doesn’t? For many students, trade school can be a compelling alternative. Trade schools, or technical schools, have gained prominence in recent years as invaluable institutions providing specialized training and practical skills for a variety of careers.

Students enrolled in trade school cite several reasons why they chose this path for themselves, often pointing to benefits like the hands-on training they receive, as well as job placement assistance and a faster route to joining the workforce. Whether you’re considering a career change or seeking a more direct route to employment, understanding the benefits of trade school could be the key to unlocking your future success!      

1. Career Focus  

Trade schools specialize in technical education. Unlike students at traditional universities or community colleges, trade students are not required to complete electives or unrelated subjects like English or geography. Instead, trade students get the opportunity to focus on a career-related curriculum. This allows them to home in on their technical field of choice—such as A/C & refrigeration, automotive repair, construction, electrical, plumbing or welding—to gain skills applicable for entry-level employment.

2. Small Class Sizes  

University or college students often attend classes in large lecture halls, where they are merely a number. In a smaller, more student-focused trade school,  instructors get to know students . Learning is split between the classroom and the shop at Apex, and students have the opportunity to learn side by side, collaborate with one another and form friendships that they may carry into their life or career beyond graduation. Small classes foster learning opportunities that can help position students for a hands-on experience.  

3. Hands-On Training

Most students who pursue a technical career path have a passion for working with their hands. Sitting behind a desk at a 9-to-5 job may not sound challenging or fulfilling to a trade student who would rather problem-solve with their hands. Trade schools give these students an opportunity to follow their dreams, feel accepted as hands-on learners and gain knowledge through experiences.  

At Apex, students have access to workshops where they use tools of the trade to practice techniques and accomplish projects. Each course is designed to introduce students to knowledge they can use in the trade after graduation.

 4. Scheduling Options

Whether you’re a recent high school graduate, a professional interested in advancing your current career or planning to enter an entirely new field in the technical industry, you need an education that fits into your busy life. Trade school is an excellent option because classes are often offered at different times to better accommodate students’ schedules.  

For example, at Apex, students can choose to enroll in day or evening classes depending on their lifestyle and needs. While day classes work for some, evening classes are popular with students who work a part-time or full-time job during the day, have family commitments or caregiving responsibilities.

5. Job Placement Assistance  

     Trade schools understand that you’re pursuing hands-on training because you’re ready for a fresh start. By completing an Apex program, you show that you’re ready to start an entry-level job in your field.

Like blood in the human body, refrigerant circulates through an air conditioning unit. It helps our homes feel comfortable, our office spaces feel cool, and gives warehouses and industrial plants the technology they need to store food and other substances or equipment at safe temperatures.

Industries have relied on certain traditional refrigerants for decades. While many still leverage these conventional refrigerants in A/C systems and equipment, some may choose to explore alternative refrigerants for the benefits they can offer. Let’s take a closer look at the difference between traditional and alternative refrigerants, including their properties, benefits and reasons for use.

What is a traditional A/C refrigerant?

Traditional A/C refrigerants include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs). You may recognize the term “freon” when you think of refrigerants. Freon is a trade name for a class of CFC and HCFC refrigerants.

These refrigerants have been widely used in A/C systems but are now being phased out of the industry because of their detrimental impact on the ozone layer.

What is an alternative A/C refrigerant?

Alternative A/C refrigerants serve as a substitute for traditional refrigerants. Alternatives are often chosen due to their less harmful properties. They are undergoing gradual adoption within the A/C industry, as older systems that run on traditional refrigerants are phased out and new systems are developed to handle alternative refrigerants.

Examples of alternative refrigerants, or freon substitutes, include the following:

Hydrofluoroolefins

Hydrofluoroolefins, or HFO refrigerants , are a new generation of refrigerants made of hydrogen, fluorine and carbon. They are used in air conditioning systems, heat pumps and commercial cooling installations. HFOs were developed to meet higher compliance standards and to replace older refrigerants like HCFCs and HFCs.

By adopting this refrigerant alternative in A/C units, businesses and homeowners may benefit from higher energy efficiency, lower cost of ownership and better performance. HFO refrigerants are spurring economic growth by creating opportunities and innovation in the HVAC and chemical industries.

Hydrocarbons

Hydrocarbons (HCs) are made of hydrogen and carbon. They are nontoxic refrigerants with various efficiency, environmental and performance benefits. HCs can be used in air conditioners, refrigeration equipment, heat pumps, foam blowing and in equipment in the food industry.

While HCs are classified as highly flammable, compliance is crucial for safety. It is considered unsafe to retrofit hydrocarbon refrigerant into an existing A/C unit that isn’t designed for flammable refrigerant.

Some alternative refrigerants, such as hydrocarbons and carbon dioxide, are more readily available and less expensive than their traditional counterparts. This can lead to cost savings for A/C manufacturers, service providers, and ultimately, consumers.

Ammonia

Systems that use ammonia refrigerant are deemed more cost effective than traditional refrigerant systems with freon or fluorocarbon. The cycle time is significantly less for the same cooling capacity, and ammonia is approximately 10 times less expensive than other cooling agents, according to kuhlmaninc.com . This freon alternative can help save on energy costs and reduce carbon emissions.

While replacing a system that relies on traditional refrigerant for an ammonia system may be more costly up front, many ammonia systems are more durable and longer lasting. There are also fewer regulatory oversights with ammonia refrigeration methods, according to kuhlmaninc.com , so expensive upgrades are less likely over the life of the system.

Carbon dioxide​

We typically think of carbon dioxide (CO2) as the substance humans breathe out. But it’s also a natural cooling agent with energy-efficient refrigeration properties. Carbon dioxide is used in air conditioners, ice machines and other cooling equipment. It’s become popular recently, but its use in refrigeration dates back a centuryor more.

CO2 refrigerant has many benefits; it’s non-toxic, non-explosive, environmentally friendly, has good thermodynamic and heat transfer properties, is highly energy efficient with a wide working temperature range, and is less costly than synthetic refrigerants.

Carbon dioxide is a good alternative refrigerant for commercial and industrial refrigeration. However, old and new units cannot be adapted or retrofitted for CO2 — the unit must be designed for the characteristics of this gas.

Reasons for Transitioning to an Alternative Refrigerant

Do all scenarios call for an alternative refrigerant? Despite the benefits of alternatives, traditional refrigerants may still be required with some A/C systems if they offer superior performance, lower costs or greater availability on the market. Ultimately, the decision depends on careful assessment to determine the most appropriate option.

Before transitioning to an alternative refrigerant, A/C professionals must ensure compatibility with the system, conduct routine safety assessments and adhere to environmental and regulatory guidelines. In addition to regulatory compliance, there are other important reasons an alternative refrigerant might be selected, including:

• Consumer demand
• Energy efficiency standards
• Technological advancements
• Phase-out mandates to protect the ozone
• Reduced operating costs
• Safety considerations

The power grid in the U.S. is a massive network of power plants, transmission lines, and distribution systems. It provides electricity to millions of homes, businesses and industries across the nation. But this critical infrastructure is showing its age. Over 70% of the power transmission lines and transformers that carry electricity across the country are over 25 years old , with the average age being approximately 40 years old.

Power demand is rising 1–2% annually, straining decades-old equipment. The complex grid is overdue for major upgrades but faces slowing advancement due to technical, regulatory and financial roadblocks. As the infrastructure deteriorates, electricians face more complex and frequent repairs, requiring them to keep up with the latest technologies and regulations.

America’s Antiquated Power Grid

One of the clearest signs of this aging infrastructure is the increasing number of power outages and blackouts experienced in different parts of the country. These outages can be caused by outdated equipment, overloaded systems, and poor maintenance. As the power grid gets older, its reliability decreases, which disrupts the electricity supply.

Climate change impacts power systems and suppliers with dire results. The lines and poles that deliver power to homes and businesses are susceptible to increasing storms, floods, and wildfires which jeopardize reliability. For example, extreme cold weather in Texas in 2021triggered generation capacity issues and crashed the state’s independent grid for days. In December 2023, New York City saw a blockbuster stormthat brought flooding rains and knocked out power to more than 500,000 people.

However, some communities are striving to improve their power systems despite the odds. They have integrated advanced meters, sensors and communication technologies to improve efficiency—but this also increases exposure to potential cyber threats.

Challenges Facing Infrastructure Upgrades

Outcomes may quicken if federal, state and investor-owned commitments begin to match the pace of technological advancements. Hurdles delaying progress include:

• Lack of consistent federal regulations and standards

Unlike roads and telecommunications, electricity delivery lacks clear national regulatory guidelines and protocols. This makes it harder to coordinate and implement system-wide upgrades.

• Investment challenges of regulated utilities

Much of the grid is owned and maintained by investor-owned utilities with regulated revenue streams. This can discourage spending on improvements that may not directly raise profits. Upgrades must be formally approved by state public utility commissions.

• Approval processes through state utility commissions are lengthy

Most oversight and planning occurs through public utility commissions in each state. These oversight boards must greenlight major capital projects proposed by utility companies before any work can begin.

• Integrating renewable sources like solar and wind generation creates new demands

Adding large amounts of variable wind and solar power to the old grid not designed for such intermittent sources creates technical and management challenges for utilities.

• Hardening the grid against climate change disasters is not prioritized

More frequent storms , floods, heatwaves and wildfires driven by climate change strain aging equipment not designed for such demands. But there are few incentives to proactively strengthen infrastructure.

What This Means for Electricians

Electricians currently benefit from the work it takes to maintain and repair America’s antiquated and fragile power grid infrastructure. The skills of electricians are needed to cope with infrastructure that is prone to failures from age, weather events, and capacity overload. Each year, electricians respond to hundreds of major blackouts and countless minor disruptions caused by an overloaded grid showing its age.

While keeping outdated grid infrastructure operational is reliable work, electricians’ long-term career growth depends on gaining experience with modern smart grid technologies and renewable energy integration advances that require an overall modernization overhaul yet to be undertaken. It will take hundreds of billions of dollarsover the next decade to modernize the grid. Until political will enables large-scale upgrades, electricians will remain relegated to short-term grid patch jobs rather than expanding renewable energy skillsets for the future.

A Brighter Future Is Possible

It’s clear that the technological know-how exists and is ready for lawmakers, engineers and electricians to take it up and reimagine the future of America’s power grid. However, overcoming institutional inertia remains challenging in the face of financial, climate and regulatory barriers. Many experts point to the successful innovation of the telecom industry as a model for electricity delivery. With this approach as their blueprint, electricians could be one important part of modernizing the power grid through advocacy, education and hands-on training.

Ductwork or ductless? For a growing number of homeowners today, the benefits of ductless heating and cooling are an appealing option. Ductless systems first gained traction in the HVAC industry decades ago in commercial buildings, but recent design innovations have made them a more aesthetically-pleasing fit for residences. Homeowners are choosing ductless HVAC systems for a variety of reasons, from energy efficiency ratings to Wi-Fi capabilities and more. Find out three of the most common reasons that ductless systems are on the rise.      

What is a ductless HVAC system?      

Ductless HVAC systems, also called ductless mini-split systems, are compact heating and cooling units that don’t require a full network of air ducts to operate. The systems consist of an outdoor compressor that works with one or more slim wall-mounted indoor air handling units mounted throughout the house. Thin refrigerant lines run between the outdoor and indoor components to remove and distribute heat.      

Keep reading to learn about three advantages of mini-split systems for residential homes.  

1. Easy to Install​

Installation for a mini-split ductless system is easier and faster than standard units with ductwork that must be incorporated throughout the home. Ductless systems require drilling holes in the wall to mount the system in each room as desired. This less-invasive installation approach enables homeowners to get climate control without renovating an old or historic home or installing modern ductwork, which can cost $10-40 per linear foot, including materials and labor.  

Once a ductless system is installed, many homeowners find they are easier to use than some traditional systems. Smart HVAC systems can offer conveniences like remote operation through Wi-Fi and settings that can be controlled via app.

2. Cost Efficient      

Ductless mini-split systems eliminate the need for ductwork to distribute conditioned air throughout a home. Installing and maintaining ductwork can be expensive. Ductwork also accumulates dust and debris over time, reducing system efficiency and requiring periodic cleaning or replacement. By choosing ductless systems, homeowners may have higher upfront equipment costs but could save on long-term operation and maintenance.      

Some ductless heat pump systems qualify for utility rebates, tax incentives, and property tax exemptions in certain areas, which further offset upfront purchase expenses. Between the potential incentives and long-term energy savings, homeowners switching to ductless HVAC can recoup costs quicker than conventional systems.

3. Energy Efficient

The Seasonal Energy Efficiency Ratio (SEER) measures ductless efficiency. Typically, high-efficiency ductless heat pumps reach SEER ratings of up to 20-30 versus central AC units rating only 14-18 SEER on average. The higher efficiency allows ductless mini-split systems to provide equivalent heating and cooling capacity using less electricity.  

Features like individual room climate control also create energy efficiency by helping to avoid heating or cooling rooms when you aren’t using them. With ductless systems, each room gets its own blower connected to an outside unit by pipes. For example, homeowners can simply set a comfortable climate in the living room, while shutting down the controls in the unused spare bedroom.

As ductless systems result in lower energy costs, this can lead to reduced environmental impact and improved indoor air quality. Ductless systems connect to the outside directly, keeping out contaminants that would otherwise build up and circulate within ductwork. Mold, mildew and other allergens can have a negative impact on the indoor environment, and ductless systems can be a healthier, more efficient alternative for some people.

What do the ancient Greeks, Benjamin Franklin , Thomas Edison and Nikola Tesla have in common? They are the forefathers of modern electricity. As scientists and inventors, their work with electricity, currents and power distribution systems was crucial for the electrical trade we have today. The work from Edison and Tesla led to electric power in homes in the late 1800s and into the 1920s when rural electrification brought electricity to more households.

The Evolution of Electrical Tools

As electricity illuminated more homes and buildings, electricians were required for installation and repair. Electricity can be dangerous and necessitates the right tools and gear. Early tools for electricians like pliers, screwdrivers and wire cutters were metal and did not protect against the risk of electrical shock. However, electrical tools have improved greatly over time and have made electrical work saferand more efficient. Let’s dive into the history of some of the most important electrical tools.

Insulated Hand Tools

The development of insulated hand tools in the 1900s was a major breakthrough for the electrical trade. Insulated hand tools such as pliers, wrenches and screwdrivers quickly became standard among electricians for their ability to protect against shocks, burns and electrocution. The plastic or rubber coating on insulated hand tools prevents the electrician from becoming a path to ground if the tool contacts an energized conductor.

Many hand tools today have a double layer of insulation to ensure backup protection in the event one layer is cut, warped or worn down. OSHA requires electricians to use insulated hand tools as a safety precaution.

Multimeter

The history of the electrical industry would be incomplete without the multimeter. This electrical measuring tool is an essential tool for electricians to measure voltage, current, resistance and other parameters. Early galvanometers in the 1830spaved the way for the first multimeters to be developed in France in 1924, which measured volts, milliamps and ohms. Handheld multimeters gained popularity in the 1960s and digital multimeters emerged in the 1980s.

The digital nature meant that electricians had more precision. As multimeters gained more special features in the 1990s, their safety and accuracy improved as well. Today’s advanced, wireless multimeters offer electricians the ability to log and graph results on a computer.

Cordless Power Drills

Advances in battery technology led to the development of the cordless drill . In the 1800s prior to cordless options, drills were bulky, corded and used mainly for industrial applications. However, in the 1900s, lead-acid batteries allowed drills to go cordless for the first time; they were popular despite their limited power and short runtime. By the 1960s, Black and Decker debuted a lightweight cordless drill that ran for a few minutes.

It wasn’t until 1991 when lithium-ion batteries transformed cordless drill capabilities. Today, lithium-ion batteries can power cordless drills with a full-day runtime, making it easy for electricians to drill holes to run wiring , sink screws and bolts to install electrical boxes, mix drywall mud, and feed cables through conduit holes.
