HVAC systems provide thermal comfort by heating and cooling indoor spaces. They also ventilate rooms by circulating fresh air and removing stale air, reducing moisture that can cause mold and mildew.

Various types of HVAC systems include furnaces and boilers to warm air, air conditioners to cool it, and ductwork to transport both heated and cooled air throughout indoor spaces. Some systems feature programmable thermostats to allow homeowners to control temperature settings. Visit https://www.taphvac.com/ to learn more.

Heating is one of the main functions of HVAC systems, and there are a variety of different options for home use. Some popular choices include furnaces, boilers, and steam radiators. Furnaces operate by converting fuel to heat through combustion, while boilers boil water and distribute it via a network of radiators. Both can be powered by either gas or oil. Another option is a radiant system, which uses electric resistance heaters to create warmth by convection.

Air conditioning is a common addition to HVAC systems, and it works by using a fan to draw air in through vents. The fan then passes it over refrigerant-filled coils, which cool the air before blowing it into the home through ducts. This helps to keep homes comfortable without consuming a lot of energy. Some systems also have multiple cooling stages, which can help to improve efficiency even more by running the system at lower temperatures for longer periods of time.

Other important HVAC systems include ventilation and air quality control, which help to keep indoor spaces healthy and clean. Many systems feature filtration systems that can trap harmful pollutants, such as dust, dirt, and pet dander. This can reduce asthma and allergy symptoms in people who suffer from these conditions. In addition, some systems can control humidity by preventing excess moisture from building up in the home, which can lead to mold and other structural problems.

Lastly, ventilation systems can help to prevent dangerous fumes and gases from entering the home, which is important for people who work with toxic chemicals. Some systems can even detect carbon monoxide and other dangerous gasses and alert homeowners to their presence.

While HVAC can be a complex topic, it’s important for people who are interested in improving their home or pursuing careers in the industry to understand this technology. With an understanding of the basics, it’s easier for people to select the right equipment for their needs and take care of it properly. Whether you’re looking to buy a new HVAC system or simply want to learn more about the technology, the best way to get started is by visiting an ATI Training Center near you.

Cooling

When you’re sitting in a cool room during a summer heat wave or staying warm and cozy during winter, you have the HVAC system to thank. These essential indoor comfort systems control temperature, humidity and air movement to make your home or business healthy, comfortable and energy efficient.

The technology behind HVAC systems is complex but essential to our everyday lives, maintaining the safety and comfort of countless homes, offices and other enclosed spaces. Whether you’re a homeowner looking to maintain your HVAC system, a business owner interested in optimizing energy efficiency or considering a career in the field, understanding how these systems work and why they matter is key.

Most people are familiar with the concept of heating and cooling, but the acronyms and technical terminology can be confusing. Some contractors and builders use the terms AC or HVAC interchangeably, but there is a clear difference between the two. An HVAC system is designed to heat and condition the air in a space, while an AC unit focuses solely on cooling the air.

Humans have used evaporative cooling for centuries, using sweat to cool the body through a process that works much like how water cools a wet surface. In 1902, Willis Carrier invented mechanically chilled air, creating the foundation for modern HVAC technology.

In order to cool air, an HVAC system uses a refrigerant that absorbs heat from the air and carries it away through ductwork and vents, which are usually located in the ceiling or on the walls. The cooled air is then dispersed throughout the space. In order to ensure the system continues to provide cooling efficiently, it is important to maintain a regular maintenance schedule.

Keeping up with the latest in HVAC technology is also crucial. The latest units feature smart controls that allow you to set timers and schedules for cooling and heating, ensuring the most cost-effective and energy-efficient operation. High-efficiency models are also able to track energy usage, helping you keep tabs on how much your system is being used and reducing the environmental impact of your equipment.

Ventilation

Ventilation is the process of providing fresh air to a space and removing stale, polluted air. It can be done through natural or mechanical means. While open windows can provide adequate ventilation for small buildings, more complex spaces such as offices and factories often require mechanical ventilation systems to ensure a healthy work environment.

HVAC systems are also used to control humidity and temperature. They can also help reduce secondhand smoke in buildings. However, it is important to note that ventilating a building will not eliminate all air pollution and smoke. The best way to control pollution and smoke is to not have it produced in the first place, such as by prohibiting smoking indoors or near the entrance of a building.

The HVAC system is a large network of ductwork, air handlers, filters and dampers. The ductwork delivers conditioned air to rooms, while the air handlers and filters clean it before delivering it. The dampers control how much air flows through the ducts. The HVAC system can also be used to heat and cool the air in a building, depending on the season and the climate.

During the pandemic, UW Facilities maintained and operated ventilation systems in accordance with ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) and Washington Labor & Industries guidelines as well as CDC (Centers for Disease Control) guidance. UW maintenance teams performed extra checks during the pandemic to ensure that ventilation systems were working correctly and to maintain high indoor air quality.

An HVAC system consists of a furnace, an air conditioner and ductwork. Furnaces burn fuel to produce heat, which is then pushed through the ductwork by an air conditioner. Then, the air is cooled by the refrigerant that is forced through an evaporator coil, which draws heat from the air and changes it to a cold liquid. The vapor is then blown through the condenser coil where it absorbs heat and returns to its cold, liquid state.

The term “HVAC” is often used to refer to the whole system of heating, ventilation and air conditioning; however, there are many other types of systems that fall under this category. The type of system you choose will depend on your budget and the needs of your space. For example, some people prefer to use a heat pump instead of an air conditioner because it provides both heating and cooling.

Maintenance

A heating, ventilation and air conditioning system is a vital component of a healthy home. It is responsible for providing warmth during colder months and cool air during warmer months, and it works with the rest of your home’s ductwork to distribute that air throughout the living spaces.

HVAC maintenance is essential to keep the system operating efficiently and at a high level of performance. This is done by regularly inspecting and cleaning components, lubricating moving parts, and performing other tasks to ensure the system is functioning properly. Performing these preventative tasks can significantly reduce the likelihood of unexpected breakdowns and costly repairs.

Preventative HVAC maintenance includes air filter cleaning, evaporator coil cleaning, electrical system inspection, and refrigerant recharge. Dirty filters restrict airflow, causing the system to work harder to achieve the desired temperature. Regularly changing or cleaning the filters allows the system to operate at peak efficiency.

Keeping the evaporator coil clean helps prevent the coil from becoming iced over, which can interfere with the efficient transfer of heat and negatively impact energy consumption. During routine cleaning, the technician removes the fan cage and sprays the coil with commercially available no-rinse coil cleaner. The coil is then rinsed off with a sprayer hose and allowed to dry completely before reattaching the fan cage.

Electrical connections and capacitors should be inspected during HVAC maintenance to identify any problems that could result in fires, overloaded equipment, or inefficient operation. The thermostats should also be inspected and calibrated to make sure they are running as efficiently as possible.

Leaking ductwork must be identified and repaired during HVAC maintenance to avoid wasting conditioned air. Similarly, a clogged condenser drain pan can result in poor cooling and moisture accumulation within the home. Regularly draining and rinsing the pan keeps it free of debris, helping to prevent the buildup of mold and mildew.

Performing preventative maintenance on your HVAC system can improve the comfort of your family and save you money in energy costs, repairs, and replacements. A good Computerised Maintenance Management System (CMMS) can help you maintain a comprehensive HVAC Preventive Maintenance program by recording the history of inspections, work orders completed, repair and replacement costs, and other details about your system’s performance. It can also enable you to schedule maintenance appointments for your properties more efficiently and effectively.

One roof may seem ordinary, but each has complexity. A contractor sees geometry, airflow, and material science. They read every slope like a coded map. Their mastery turns raw materials into enduring shelters.

Roofing contractors embody the balance between craftsmanship and guardianship. They are builders, planners, and advisors at once. Their contribution extends beyond the visible structure. They create comfort, safety, and peace under every roof.

Standing Strong: The Legacy and Future in Supporting Workers

July 23, 2025

Uncategorized No Comments

On Labor Day, we celebrate the profound social and economic contributions of the country’s workers. But this holiday also reminds us of a legacy of workers’ struggles that must not be forgotten.

Health system leaders have a unique opportunity to seize the moment and make worker well-being a core organizational value. To do this, they must embrace strategies that foster open communication and empower workers.

West Bank’s 130-Year History

As one of Iowa’s oldest existing businesses, West Bank has seen its share of change over the past 130 years. It’s survived recessions and depressions, 23 U.S. presidents, and the changing landscape of the economy and technology. But it’s been the company’s deep investments in people that have anchored its stability and allowed it to thrive regardless of what happens.

The company has been at the forefront of supporting the needs of working families throughout the Midwest, and in 2024, it will celebrate its 130th anniversary in a way that highlights the role its employees play in building strong communities. During the past decade, it has invested more than $1.4 billion in the communities where its employees live and work.

In the West Bank, Israeli infrastructure projects like the ‘Samaria road’ allow Israel to move its settlers across the Palestinian territory separately from Palestinians. Khalil Tafakji, an expert on Israeli settlements, says this allows the Jewish state to lay the groundwork for annexation.

Following the Oslo Accords, which facilitated the segregation of the West Bank into cantons of varying degrees of Palestinian control, the Palestinian Authority now controls less than a fifth of the territory. The remainder is largely under Israeli occupation (or, in some cases, combined Palestinian local governance with Israeli control). Settlement expansion has continued unabated since the accords, and the issue of Jerusalem continues to fester as Israel maintains its refusal to recognize or negotiate over the Temple Mount, which is home to Islam’s holiest site, the Al-Aqsa Mosque.

The Legacy of Cesar Chavez

After an introduction by Rio Salado Administrative Services Program Manager Reina Ferrufino, Karol Schmidt presented a detailed and informative talk about the life and work of Cesar Chavez. The presentation included archival footage and interviews with people who knew him well or worked closely with him.

Chavez was a civil rights, Latino, and farm labor leader; a religious and spiritual figure; a social entrepreneur; a champion for militant nonviolent social change and education; and a crusader for environmental and consumer rights. He forged a national coalition of students, middle-class consumers, trade unionists, farmers, and minorities and was an inspiration to millions.

The seed for his activism sprouted in the dusty California community of Delano and grew into a national movement. In 1974, Chavez led a 110-mile march that resulted in the E & J Gallo winery signing the first collective bargaining agreement for farm workers and changed working conditions in ways that have had a lasting impact.

Throughout his career, Chavez was a tireless worker, organizer, and advocate who inspired many to stand up for what they believed in. He was also a man of great humility who, one-on-one, was far more soft-spoken and humble than the fiery activist he is renowned for being in the media. In fact, the son of Chavez, Paul, visited the West Bank campus on Monday to pay respect to his father and administer the Oath of Allegiance to a new group of workers.

The Future of the Labor Movement

It is hard to say if the current moment will be a period of reversal or renewal for the labor movement. Certainly, there is a sense of urgency to the labor movement right now as it faces challenges.

Unions are struggling to maintain their relevance in a world where the economic and political environment is hostile. The growth of private-sector “right-to-work” laws and the rise of precarious work threaten their traditional base of membership and power. Corporations are moving jobs to countries with lower wages and fewer regulations, and their focus on short-term shareholder value undermines the long-term health of their companies and workers.

There are signs that the labor movement is adapting to these challenges. A number of unions have re-branded and refocused their efforts. Many of them are experimenting with new models, including digital organizing and partnerships across industries and geographies. And a number of unions have started to rethink their role in the political arena, seeking to build alliances with Democrats and other progressive groups to address economic issues that go beyond the bargaining table.

And, despite the political climate, American public opinion remains fairly positive toward unions. As my colleague Megan Brenan explained in her analysis last September, 90% of Democrats approve of unions, while only 57% of Republicans do so. That gap is consistent with long-term trends, going back to the first time Gallup asked this question in 1936.

The Value of Unions

Unions benefit the broader economy in a wide variety of ways. They increase productivity by aligning worker interests with those of businesses, which reduces turnover and makes work more pleasant. They increase the share of national income that workers receive by lowering inequality. And they create good jobs, reducing poverty and driving economic growth.

They led the fight for a better quality of life for workers, bringing us things we take for granted today like weekends, safety provisions, and equal pay for equal work. They help to end bullying and harassment at work, push for fair-trade agreements that lift standards worldwide, and promote policies that make our families and communities stronger, such as expanded family and medical leave, affordable health insurance, and pension benefits.

The political influence of unions also gives their members a stronger voice in politics, increasing the likelihood that they vote and contribute to the causes they believe in. Studies show that a 1 percentage point increase in union density results in between 3.1 million and 4 million more votes being cast in a given election. This is why it is so important to continue strengthening our country’s unions. But there are some things that need to be addressed to ensure that unions remain a key tool in our democratic process. These include making it easier for people to join them and ensuring that their representation is objective.
