to drink. In this case a slightly more powerful type of water filtration would be needed. Other instances in which you might need to have a much more aggressive method |
of water filtration is when traveling in foreign countries or in the event of a major disaster such as a flood. The charcoal based water filter is one of the |
most common of all types of water filter. This is the type of filter that you would find in a typical water filtration pitcher such as the Brita pitcher, and |
also in most types of on-the-faucet water filters. These types of water filter usually have a cartridge that contains a combination of charcoal and sand. When water is poured through |
the filter, the charcoal removes chlorine, chemicals and some other contaminants and the sand filters out any larger particles. The end result is clear looking and clean tasting water. For |
filtration of outdoor water sources when camping and backpacking, a portable reverse osmosis system is one option. Reverse osmosis purifies water by passing it through a semi-permeable membrane, which traps |
nearly 100% of all contaminants, both chemical and biological. Since biological contaminants such as bacteria and viruses are a major threat in rivers and lakes, it is important to have |
a water filter that is able to safely remove them. One disadvantage of reverse osmosis is that the process is extremely slow and wastes a lot of water. A reverse |
osmosis filter can also be a valuable part of any emergency supply kit, because contaminated water is a common hazard encountered in emergency situations. Because reverse osmosis is capable of |
even removing viruses from water, this type of filter can save lives in countries where there is an extreme shortage of safe drinking water. Another one of the more popular |
types of water filter is the ceramic microfilter. Like a reverse osmosis system, a ceramic filtration system also uses an ultra-fine material to filter the water. In this case, porous |
ceramic is used as a filter. The ceramic is fine enough to trap even most bacteria and some types of virus, so they can successfully purify water in most parts |
of the world. Many ceramic-based water purifiers also incorporate charcoal and sand into the filters to improve taste while offering maximum filtration at the same time. To read more about |

an HVAC Technician? The typical salary of an HVAC technician depends on many factors such as the type of HVAC job, employer location, level of experience, and whether or not a union is involved. When it comes to HVAC, salary is usually implemented in the form of hourly wages. Most |
HVAC technicians, regardless of their training, begin their careers at a relatively low rate of pay, but their wages rise gradually as they increase their skills, knowledge, and experience. So, what are some average HVAC salaries? Based on national estimates, yearly wages for HVAC and HVAC/R technicians break down this |
way: * - The bottom 10 percent earn $26,490 or less. - Median wages (50th percentile) are $42,530. - The top 10 percent earn $66,930 or more. The pay scales of similar employers, even within the same city, can sometimes vary dramatically. HVAC/R technicians that install and service commercial or |
industrial systems generally get paid the most. Unionized employers also tend to have much higher wages than non-unionized ones. However, you can expect a large chunk of your wages from any union job to go toward paying for union fees, insurance, and other benefits. Many HVAC technicians maximize their income |
by working longer hours during peak seasons (summer and/or winter). Additional wages can also come, in some cases, from earning commissions on the sale of new equipment or service contracts. Are There Any Downsides to Working in the HVAC Trade? For the people who turn it into a long-term career, |
HVAC is a lifestyle. Many HVAC technicians reap a great deal of personal satisfaction from their work. But, like any occupation, the field of heating, ventilation, and air conditioning has its upsides and downsides. It's not a career for everybody. You've got to be 100 percent committed in order to |
succeed. Here are some of the possible drawbacks of being an HVAC or HVAC/R technician: - Physical hazards—It can be grueling and hard on your body. Installing or servicing HVAC systems often requires heavy lifting, crouching, and kneeling—including in tight places like attics and crawl spaces. Other physical hazards a... |
exist such as the potential for cuts, scrapes, electrical shock, burns, or muscle strain. And, although rare, working with refrigerants without appropriate safety equipment can result in injuries like frostbite, skin damage, or even blindness. - Uncomfortable working conditions—It frequently involves working outdoors i... |
and cold). - Mental fatigue—In addition to being physically demanding, HVAC work can also be mentally tiring. That's because you must remain alert and focused in order to solve problems and avoid injury or costly mistakes. Plus, no matter how experienced you are, there is always a lot to learn. |
HVAC technology changes quickly, so being an HVAC technician requires staying on top of the latest developments and adding that knowledge to what you've already learned about older systems that are still in use. That makes the job sometimes feel overwhelming. As HVAC technology improves, much of it is also |
becoming more and more technically challenging to work on. - Fluctuating work hours—Employment in the HVAC trade can sometimes be subject to seasonal fluctuations, particularly for technicians without much experience. It is common for many HVAC service technicians to work very long hours during peak seasons (summer and... |
by a reduction in hours (often less than full time) during the slower seasons. The peak seasons can be extra difficult if you have a family since working overtime and being on call at all hours (including weekends) can mean you're not able to spend as much quality time with |
those you care about. On the other hand, slow weeks are also inevitable, so you have to know how to account for the ups and downs in your personal finances. - Irritable customers—Since many service calls happen when customers are in distress over failing heating or cooling equipment during extreme |
weather, HVAC technicians sometimes must deal directly with people who are cranky and impatient. Tempers are heightened when a problem can't be fixed right away because a part needs to be ordered. - Delayed gratification—It takes time—usually at least five years—to develop the skills that enable you to begin making |
what are considered good wages in the HVAC industry. As a new technician, you should expect the starting pay to be lower than what you might be hoping for. You have to be willing to stick it out and learn everything you can in the meantime. What are the Good |
Things About Working in HVAC? The downsides of being an HVAC technician are balanced—and some might even say overcome—by the many positive attributes of the HVAC trade. Here are a few of them: - A sense of accomplishment—It can be intensely rewarding to fix problematic equipment or install new systems |
since it means that your hard work directly impacts the ability of people to feel comfortable in their environments. You have the chance to make someone's day if they were freezing (or sweating) prior to your arrival. Plus, looking back on a job well done often leads to a great |
feeling of personal satisfaction, regardless of how difficult it might have been. - Built-in exercise for mind and body—Despite the occupational hazards, being an HVAC technician can help you stay in shape—physically and mentally. - Variety—Every day is bound to be somewhat different. You won't be stuck in an office. |
Instead, you'll get to solve a variety of problems and meet new people. And the fast pace of busy times helps the work days pass quickly. - Pride—Because HVAC technicians can impact the well-being of people and the environment, they often feel a great sense of personal responsibility and pride |
of purpose. - Stimulation—Opportunities for learning something new happen on a frequent basis, which means boredom is rare. As the HVAC industry moves closer and closer toward full computer automation for heating, ventilation, and air conditioning systems, the chance to develop advanced skills and knowledge also increa... |
you've established yourself in the trade, there is great potential for making good money. And the job security can also be good. This is particularly true when you consider that HVAC skills are portable, and the work must be performed on location, which means that HVAC jobs are not subject |
to foreign outsourcing. What Personal Characteristics Do I Need for an HVAC Career? People who succeed as HVAC technicians possess key traits that enable them to handle the challenges of the occupation while taking advantage of the benefits. It's important to keep in mind that those who find long-term success |

aptitude for mechanical, hands-on work - Strong interpersonal skills - Common sense - The ability and willingness to learn - Determination and a strong work ethic - An interest in the science behind HVAC technology - Good problem-solving abilities How Do You Become an HVAC Technician? There is more than |
one path to establishing a career in heating, ventilation, and air conditioning. When asking, "How do you become an HVAC technician?" it is important to consider that there are essentially four different ways to begin going about it: - Obtaining formal HVAC training from a high school program or post-secondary |
school - Entering a formal apprenticeship program for your training - Joining the Armed Forces and receiving military HVAC training - Pursuing an entry-level HVAC position without any formal training and hoping that you find an employer willing to teach you everything informally on the job (an increasingly rare circums... |
Each option has its advantages and disadvantages. However, most employers generally consider formal training a must before they will even consider you for an open position. Here are some things to consider about post-secondary training at an HVAC school: - Most HVAC training programs at technical and trade schools take |
between six months and two years to complete. - Programs that last a year or less generally award a diploma or certificate of completion. Those that last two years usually award an associate's degree. - Shorter certificate or diploma programs are often designed only to teach students the basics of |
one of the three main areas of HVAC/R: (1) residential heating and air conditioning, (2) light commercial heating and air conditioning, or (3) commercial refrigeration. - Most well-respected HVAC training schools offer programs that are accredited by at least one of the following agencies: HVAC Excellence, the National... |
Construction Education and Research (NCCER), or the Partnership for Air-Conditioning, Heating, and Refrigeration Accreditation (PAHRA). - Taking the right courses in high school can help you better prepare for HVAC school. These include subjects such as mechanical drawing, basic electronics, math, computer science, and... |
also be beneficial to gain some basic knowledge of electrical and plumbing work. - HVAC schools are designed to give you a head start in the acquisition of your skills, but it will likely take a few years of working experience as an assistant HVAC technician after you graduate before |
anyone will begin to think of you as proficient. Another popular and advantageous way to receive formal training is through an apprenticeship. Here is what you should know about HVAC apprenticeships: - In general, apprenticeship opportunities pop up only periodically depending on the needs of employers, both unionized ... |
- Apprenticeships are often a pathway to national certification in the HVAC industry, and they can even allow you to earn college credits. - In order to reap all of the benefits of a formal HVAC apprenticeship, you'll want to find an apprenticeship program that is registered with the Office |
of Apprenticeship, which is part of the U.S. Department of Labor's Employment and Training Administration. - Most apprenticeships allow you to earn a wage while you learn. And, if you are part of a registered apprenticeship program, your paycheck is guaranteed to increase over time. Unionized apprenticeships offer the ... |
advantages of working under the protection of a union contract and, usually, receiving insurance and pension benefits. - Apprenticeships usually last four to five years, and they include both classroom instruction and hands-on training on the job. After completing a five-year registered apprenticeship, you can become a... |
HVAC field. - The organizations with the most HVAC apprenticeship opportunities include, in no particular order: (1) Air-Conditioning Contractors of America (ACCA), (2) Mechanical Contractors of America (MCAA), (3) Plumbing-Heating-Cooling Contractors (PHCC), (4) Sheet Metal Workers' International Association (SMWIA), ... |
Journeymen and Apprentices of the Plumbing and Pipe Fitting Industry of the United States and Canada (UA). - Apprenticeship openings are often highly competitive. Plus, you must meet the minimum requirements of whatever apprenticeship program you are applying for. Organizations that offer or coordinate apprenticeships ... |
candidates that have at least a high school diploma (or equivalent), good math and reading skills, above-average manual dexterity and hand-eye coordination, strong mechanical aptitude, patience, dependability, the ability to get along well with other people, and a desire to do whatever it takes to learn the trade. As p... |
of the application process, you may also be required to take aptitude tests and attend multiple interviews. - Completing an HVAC program at a technical college or trade school can sometimes give you a leg up on the competition when applying for a registered apprenticeship. Regardless of how you get |
your HVAC training, there are a number of other things to keep in mind about the HVAC trade and finding work in it. Consider the following points: - Many employers look for HVAC professionals with at least two to five years of on-the-job experience. Schooling alone, while beneficial, is often |
not enough—particularly for openings at larger companies. - In order to break into the trade and get the experience you need, you might have to spend a few years working for a smaller HVAC company at a lower wage than you might be expecting. The more you are willing to |
swallow your pride and do whatever is necessary to gain experience, the more opportunities you will have at the beginning of your career. - In many regions, you are more likely to land your first HVAC job during a peak season (summer or winter) since that is when demand for |
HVAC workers increases. - Employers want workers who will stick around for the long haul. That's why many of them prefer to hire people who've completed a formal HVAC program. Completing an HVAC education is a sign that you aren't just looking for a temporary job but, rather, have put |
your heart into making HVAC your career. - As you seek to gain experience early in your career, it's best to go for variety, if possible, in the type of HVAC work you do. Some people in the trade get "stuck" in just one particular area (such as installation) and |
find it difficult later on if they wish to move into a different HVAC specialty that they might enjoy better. - It pays to be assertive and proactive, especially when it comes to increasing your HVAC knowledge. You'll have better job security and advancement opportunities if you can become the |
"go-to" person for technical information and troubleshooting know-how about the equipment your employer sells and services. As you begin your career, it is essential to ask a lot of questions, pay close attention, and study, study, study. And, as you continue your career, the need to learn never stops. There |
will always be more to know. - Like in any other trade, the better you are at your job, the more quickly you can climb the HVAC career ladder. - It is impossible to learn everything you need to know in two years or less. So, although trade school can |
give you a great head start on the fundamentals, you should expect to begin your HVAC career in a "helper" or apprentice role as you continue to learn. It generally takes at least five years of on-the-job experience before you're ready to work on your own. - Since demand for |
HVAC technicians can sometimes be prone to seasonal fluctuations, it is important to learn how to manage your money in a way that allows you to ride out any downtimes comfortably. - Long-term success as an HVAC technician hinges a great deal upon your reputation. So it's important to develop |
a courteous and respectful attitude early on, to never cut corners, and to let the quality of work you perform speak for itself. - Persistence and enthusiasm are the biggest keys to landing your first job in HVAC. Employers look for people who are willing to commit to hard work. |
You can improve your chances of finding employment by always acting polite and professional, following up repeatedly with the people in charge of hiring, and demonstrating to them that you're not an arrogant "know-it-all" but are, instead, humble and ready to learn and take on all of the challenges inherent |
to HVAC work. How Do You Get HVAC Certification? When asking, "How do you get HVAC certification?" it is essential to understand that some certifications are required while most others are voluntary. Even voluntary certifications, however, can help you advance in your HVAC career since most employers like to see |
official acknowledgment of your competencies. But knowing how to obtain HVAC certification is just one aspect of this issue. You also need to understand what it all means. Here are the most important things to remember: - Regardless of which area of HVAC/R you choose to work in, you will |
be required to obtain at least one type of certification from the U.S. Environmental Protection Agency (EPA). Section 608 of the Clean Air Act of 1990 requires anyone who services equipment that uses specific refrigerants to take a test to prove that they know how to properly handle, recycle, and |
dispose of materials that can damage the ozone layer. - EPA Section 608 certification is broken down into four types depending on the kind of equipment you will be working with: (1) Type I for small appliances, (2) Type II for very high-pressure appliances, (3) Type III for low-pressure appliances, |
and (4) Universal for all types of HVAC/R equipment. - HVAC students enrolled in formal training are often required to take the EPA Section 608 Universal certification test as part of their program. - Although not required by the EPA, R-410A certification covers an especially dangerous type of refrigerant in |
greater detail than what is found in the EPA Section 608 test. R-410A refrigerant is used at a much higher vapor pressure than other refrigerants and, therefore, requires different tools, equipment, and safety standards. R-410A is increasingly replacing some of the older ozone-damaging refrigerants that are being phase... |
Other types of professional HVAC certifications are designed to verify the real-world skills and working knowledge of HVAC and HVAC/R technicians who've had at least a year or two of on-the-job experience. Certification is offered by independent organizations in many different specialty areas such as residential and co... |
heat pump service and installation, gas heat, electric heat, oil furnaces, hydronics, air distribution, and commercial refrigeration. - The two most recognized providers of professional-level certifications in the American HVAC/R industry are (1) HVAC Excellence and (2) North American Technician Excellence (NATE). Obta... |

You can also obtain your EPA Section 608 certification through such providers. - A certificate of completion (or diploma) from a formal HVAC training school is NOT the same thing as professional-level certification from organizations like HVAC Excellence or NATE. ... |
HVAC Classes Take? Formal HVAC programs at technical colleges and trade schools vary in length. A lot depends on the type of credential you're after and how in-depth you want your schooling to be. So, how long do HVAC classes take? HVAC programs that award certificates or diplomas typically last |
one year or less. Some take as little as about 18 weeks to complete. With these shorter programs, you often must choose to study just one of three specific areas: (1) light commercial air conditioning and heating, (2) residential air conditioning and heating, or (3) commercial refrigeration. Associate degree programs |
in HVAC/R technology, on the other hand, are designed to last two years and are often more comprehensive. How Much Does HVAC School Cost? The cost of HVAC schooling varies significantly depending on where you go to school and whether you choose to pursue a certificate or associate degree. So, |
how much does HVAC school cost? Basic program costs, including tuition, can range from as little as $2,000 or less to as much as $35,000 or more. The more expensive programs sometimes have a wider range of HVAC equipment and tools in their labs for better hands-on learning, although it |
is best to tour any school you are considering and check out their facilities to make sure you'll be getting good value for your money. Books and supplies are sometimes an extra expense and can cost as much as $4,500 depending on the program. Financial aid in the form of |
loans and grants are frequently available from the federal government for those who qualify. And some states offer financial assistance through their own retraining programs for unemployed workers. What Can I Expect to Learn in My HVAC Training? HVAC schools are set up to teach the fundamentals of what you |
need to know to begin working as an HVAC technician at the entry level. Ultimately, HVAC involves learning at least the basics of about five different trades competently, including electrical work, plumbing, welding, pipefitting, and sheet metal. HVAC education programs vary in their curriculum, but the ones that are a... |
