These regulations typically specify a maximum gallons per flush (GPF) allowed. Dual-flush toilets allow users to select a lower flush volume for liquid waste and a higher volume for solid waste.
- Water-Efficient Faucets and Showerheads: Plumbing regulations often mandate the installation of water-efficient faucets and showerheads that restrict water flow without compromising performance. These water-conserving plumbing fixtures are designed to reduce water wastage during everyday use, while flow rate limits specify maximum flow rates.
- Greywater Systems : In some areas, regulations support the use of greywater systems . This technology captures and treats wastewater from sinks, showers, and laundry machines for reuse in activities like irrigation, toilet flushing, or outdoor cleaning.
- Rainwater Harvesting: Certain regions have regulations promoting the use of rainwater harvesting systems. These systems collect rainwater from roofs and store it for non-potable uses, such as landscape irrigation.
- WaterSense Certification: The EPA has established the WaterSense program , which sets criteria for water-efficient plumbing fixtures. Products bearing the WaterSense label meet these criteria and are encouraged by regulations for their use.
- Leak Detection and Repair: Some plumbing codes require regular inspection and maintenance to detect and address leaks promptly.
- Water Metering : Many municipalities have regulations in place that require water metering for residential and commercial properties. Metering helps track water usage and can encourage conservation by billing based on consumption.
- LEED Certification: This certification helps save millions of dollars’ worth of water and billions in energy costs. For a building to attain full LEED certification, it must meet three requirements: water-efficient landscaping, innovative wastewater technologies, and water use reduction by at least 40%.
- Education and Incentive Programs : In addition to traditional regulations, some areas have implemented educational programs and financial incentives to encourage water conservation. These initiatives may include rebates for purchasing water-efficient fixtures or educational campaigns to raise awareness about water conservation practices.

In summer, the process is reversed to cool the space. This efficient technology reduces energy consumption and greenhouse gas emissions, and it also offers sustainable, renewable heating and cooling solutions. Homeowners also notice more consistent temperatures throughout their homes, low noise, and a 20+ year lifespan of the system.
Environmental benefits of geothermal heating

Geothermal systems significantly reduce greenhouse gas emissions due to their low carbon footprint. By tapping into the Earth’s stable temperatures, these systems avoid the burning of fossil fuels and lessen the release of carbon dioxide and other pollutants. This endless source of energy ensures that geothermal systems can operate for decades without depleting their fuel source.
They also don’t rely on external factors like sunlight or wind, and this consistency makes them a reliable energy source, contributing to grid stability and reducing the need for backup power sources that may be less environmentally friendly.
Cost benefits of geothermal heating
Compared to a traditional HVAC system, geothermal heat pumps use between 25% and 50% less energy , which can result in lower monthly energy bill. Local and federal tax credits may be available to help homeowners and business owners offset the cost of geothermal systems. Installation is significantly more costly than a traditional HVAC; however, the long-term savings of a geothermal heat system is a compelling reason to spend more upfront.

How Electricians Install EV Charging Stations | Apex
The electric car market has grown exponentially in recent years. Motorists are getting more comfortable with hybrid and battery electric vehicles, and many are choosing to purchase EVs when it’s time for a new vehicle. EV drivers benefit from lower to no fuel costs, along with a more environmentally friendly transportation option in the face of increasing climate laws and regulations.
In fact, EV sales exceeded 10 million in 2022 , and the sale of electric cars more than tripled from 4% in 2020 to 14% in 2022. As the electric car market continues to expand, there is a need for EV charger installation electricians. EVs require residential and commercial charging stations, as well as electricians with the knowledge and hands-on skills to not only install them, but also ensure they adhere to the National Electrical Code (NCE).
Here’s how electricians—with their expertise in wiring, electrical codes and safety—can help to accelerate the future of electric vehicles through residential charging station installation.
Understanding EV Charging Stations
Charging stations installed at residential homes ensure that EV drivers have access to power when they need it. Charging stations are not as widely available as gas stations, so many homeowners prefer to install a convenient charging station in their garage. The two most common residential EV charging stations are:
Level 1 charging
Level 1 charging stations are the most common for residential use, as they use a standard 120-volt outlet. Many modern garages already have this outlet type installed, making this a cost-effective choice for homeowners. However, level 1 charging is the slowest, and some homeowners may contact an EV charger installer to upgrade for faster charging.
Level 2 charging
Level 2 charging stations can’t plug into a typical wall outlet—instead, they require a 240-volt special plug for homes. An EV charger installer must install a level 2 unit, which gives motorists the opportunity to charge an EV in about two hours.

Assessing the Electrical System
It’s important that a skilled electrician conduct a thorough assessment of the existing electrical system in the home before installing an EV charging station. Assessments ensure that the electrical panel is up to code and can support an EV charging station. Sometimes, the electrical panel may need an upgrade to accommodate the increased electrical load.
Residences equipped with level 2 vehicle chargers necessitate a 200-amp service. In cases where the house is equipped with a 100-amp electrical panel, an electrician will need to upgrade it to a 200-amp.
Code Compliance and Location
Licensed electricians have hands-on skills and code compliance knowledge to ensure that residential EV charging stations adhere to local electrical codes and regulations. In addition to compliance with EV charging station safety, electricians can help advise homeowners on choosing the right location for their EV charging station. Many EV charging station cords are approximately 15 feet long. Electricians can help residents consider the desired parking space proximity and the length of the charging cord when installing the charging outlet.
Safety, Testing and Troubleshooting

Electricity poses unique safety risks, whether it’s a bathroom light fixture or an EV charging port. Qualified, highly trained electricians emphasize safety precautions during installation, such as proper grounding and insulation. They also use high-quality materials and components to ensure longevity and safety for residents and their vehicles.
Electricians may perform a number of testing procedures to ensure the EV charging station functions properly, including verifying the voltage, current and power outlet. Electricians can also instruct homeowners on how to safely use their new charging station.
Despite safe installation and thorough instructions, homeowners may find they need maintenance from time to time. Electricians can also provide regular, scheduled checks and troubleshooting to reduce risks posed by a charging station.

History of HVAC Tools | Apex Technical School
HVAC systems—that is, heating, ventilation, and air conditioning —have been used to make indoor spaces more comfortable for hundreds of years. And in the case of indoor heating, people as far back as the Romans were enjoying warm homes and businesses thanks to their early heating technologies. As HVAC systems evolved, so did the tools and equipment needed to maintain them. Find out more about the tools HVAC technicians have used, and still use, to work on today’s air conditioners and furnaces.
Who invented air conditioning and indoor heating?
Air conditioning is a modern concept, developed by Willis Carrier in 1902. The American engineer needed to solve a humidity problem at a printing company in New York, so he invented a series of coils and fans that cooled the temperature and dehumidified the building. Frederick Jones, an African American, invented the first portable air conditioning unit.
Indoor heating is even older than the history of air conditioning. Humans have been heating indoor spaces for centuries, using various methods and systems. The heating systems we use today are attributed to the Romans, who were the first to circulate warm air under floors and behind walls of homes and buildings. Wood and coal powered these early systems, but eventually these sources were replaced by steam and forced-air systems.
The tools used for installation and maintenance are just as important as the air conditioning and heating systems. Without the right tools, HVAC technicians couldn’t keep units in safe working order . But when HVAC was invented, the Romans and Willis Carrier couldn’t have imagined some of the tools technicians use today! Let’s dive into the history of common HVAC tools.
Multimeter
Like the air conditioning unit, the first multimeter can be traced to the early twentieth century, although its inventor is unknown. The first multimeters were used for general electrical measurements and were adapted by technicians to be used on HVAC systems.
As HVAC systems grew more complex, multimeters became specialized and included measurements for temperature, pressure, humidity and more. Today, digital multimeters are common in the HVAC industry; they are more accurate, easier to use and offer more measurement capabilities than the first multimeters of the early 1900s.

Tube Cutter
A patent for the tube cutter was filed in 1895 by John Kelsoe Fitzpatrick, although many unnamed individuals contributed to the evolution of the tube cutter throughout history. The first tube cutters were used in the plumbing and pipefitting industry, but as HVAC technologies emerged, tube cutters became an indispensable tool for technicians to efficiently cut tubes and pipes during installation and repair. Technicians today use tube cutters to slice through copper, aluminum and plastic pipes.
Refrigerant Weight Scale

The refrigerant weight scale is an important tool for HVAC technicians because it helps them measure the weight of refrigerant during the charging or recovery process. HVAC technicians know they are adding or removing the correct amount of refrigerant thanks to this valuable tool. Specific refrigerant levels ensure the system runs efficiently and safely, as it prevents over- and undercharging—problems that can cause damage or poor performance.
The inventor of the refrigerant weight scale is unknown, mostly because there have been many individuals throughout history who have improved upon this device, such as engineers, scientists and manufacturers. The development of scales and weighing systems in general can be traced back to ancient civilizations. Today, many manufacturers produce refrigerant scales with different features and capabilities to meet the specific needs of the industry.
