The Role Of Our Home Air Conditioner And Heater

In terms of maximizing our comfort in our own homes ? something we go to great lengths to achieve ? the proper functioning of our air conditioner and heater is paramount to our success. Determining, and ensuring, the maximum efficiency of these systems first depends on understanding their operation.

We all know that our home air conditioner and heater are used to adjust our interior temperature. The air conditioner lowers the temperature in the home so that we are comfortable in warmer weather; in contrast, the heater is used to elevate the temperature in the home so that we are comfortable in colder weather. But the air conditioner and heater also play roles in moderating humidity within the home subsequently affecting our comfort level.

Humidity is defined by the level of moisture in the air. Humidity can vastly affect our comfort level; as a point of reference, the human body positively responds to a relative humidity level between 20% and 60%. When the outside temperature is between 20?F and 70?F, the humidity level within in our homes is generally within this comfort level. But in more extreme temperatures, the humidity level ? along with the temperature ? inside our homes must be modified to maximize comfort.

When using the air conditioner and heater, humidity levels will also adjust accordingly. However, when the humidity level drops too low, those inside the home will often complain of dryness of the skin, irritation of their throat and eyes, and overall discomfort. Most people, in an effort to maximize comfort, will use a humidifier along with their air conditioner and heater. A humidifier will keep the humidity level consistent in the home.

The modern air conditioner and heater allows us to be completely comfortable no matter what the temperature outside. The humidifier, added to these conveniences, can take your comfort to the next level.

Benefits Of A Portable Air Conditioner

There are mostly three kinds of air conditioners which are used for commercial and domestic purposes. These are:

- The central air conditioners,
- The window air conditioners, and
- The portable air conditioners.

While the central air conditioners are meant for entire houses or offices, the window and portable air conditioners are meant for a smaller area, generally a room. The central air conditioners require a healthy investment and also your house needs to have the provisions to have it installed. Window air conditioners also need to be fitted to the window or a wall and requires installation facilities.

Portable air conditioners are much better on that count as there is no installation hassle and you can just put the plug in the socket and enjoy the nice cooling effects of an air conditioner.

Of course, being portable also allows it to be carried anywhere we want them to. For commercial purposes, the portable air purifiers are generally used in conjunction with the central air conditioners. Even with the best laid out duct network and proper outlets in a large factory floor there remains a few hot spots where air form the central air conditioner do not reach. For such areas placing a portable air conditioner can solve the problem. So, portable air conditioners can be of great benefit to many a business and warehouse owners. A comfortable environment ensures that their workers can focus on their work and not worry about other basic things.

Portable air conditioners are great for domestic purposes also. If you have a small family and most of the rooms in your house are not occupied at one given time, then you can go for portable air conditioners. That way you don?t have to invest separately on air conditioners for each room but carry your portable air conditioner where you are. When you are watching a movie on your television, place it in the living room. When it s time for bed you can just move it to your bedroom.

Portable air conditioners are also generally very durable. They are also equipped to deal with the most severe environments.

The portable air conditioners these days available in the market are based on two kinds of technologies ? they use either the Freon technology or the evaporation technology. Though the latter is a bit expensive, it is the most effective and popular version these days.

Air Conditioners

It's that time of year again. Things are starting to heat up, the snow is melting and it's time to start looking for a new air conditioner or swamp cooler. Along with the warm weather comes the allergy inducing pollens and debry in the air. If you have allergies, you may want to invest in an air conditioner with air purifying and air cleaning features. If you live in a dry climate, you may want a humidifier. Some air conditioner systems may include all of the above features, and more. This article will tell you what to look for in an air conditioner and help you decide what type of air conditioner system will be right for you this summer.

There are many types of air conditioners, and many variables that can affect which air conditioner you purchase. If you are looking at the long term and live in a climate with both extreme summers and winters, you may want a system that is both an air conditioner and a heater. If you would like to cool or heat only certain areas of your house, or particular rooms, to conserve energy, or just for convenience, a portable air conditioner may suit your needs. A portable air conditioner can also be taken on trips to relatives, to the cabin by the lake, on a boat, or a number of other places.

A dry climate can irritate your skin causing it to become too dry and begin to crack. For those who have a hard time coping with a dry climate you may want to look at air conditioners that includes a humidifier feature. You can create your own refuge from the heat and dryness of the environment that surrounds you. On the other hand, you may live in an overly humid climate, in which case you may consider purchasing a dehumidifier to get that sticky wet feeling off of your body that those who have lived in humid climates understand.

If you have allergies, you may want an air purifier feature attached with your air conditioner. When looking for air purifiers, be sure to find out if it is a HEPA, a brand well known for removing toxins and allergens from the air through their powerful HEPA air filters. HEPA and activated carbon technology can remove the smallest airborne particles and eliminate noxious gases, chemicals, and odors. Separate air cleaner filters eliminate virtually all irritants, including infectious microorganisms. Check the description of your air purifier before you purchase it, to see how powerful and effective it is, for example, for how many square feed it is guaranteed to purify the air. Some air purifiers are good for purifying the air in a single room, while others may purify your whole house.

Evaporative coolers and swamp coolers or air conditioners work by soaking water through foam like filters. As the water evaporates, the air flowing through the filters cools significantly. The evaporating water takes the heat from the pads. A fan inside the unit sucks the air through, speeding up the evaporative process and blowing the cool air into your home or office. The pads can catch much of the bad air and keep it from entering your home or office as well.

Be sure to research your air conditioners, swamp coolers, humidifiers, and evaporative coolers as this warm season begins, so that you can find one that is most suitable to your needs. There are many types of air conditioners with a variety of features that may or may not be best for you.

Air Conditioners - How to Cut Running Costs in Half

In today's world, most people have invested in one form of an air conditioner or another. We have either window air conditioners in our homes or central air conditioners. They keep us cool in the extreme summer heat without fail; however, have you ever set back and looked at the costs of running an air conditioner? When compared to the common household fan the amount of electricity required to run an air conditioner is phenomenal.

When using an air conditioner there are many different factors that can directly affect the cost of running it. These factors include the geographical location of your home, where you live and the amount of work the air conditioner has to do greatly influence the cost. If you live in an area that has mild summers and extremely cold winters, obviously your air conditioner will not have to work as hard. However, if you live in an area, that has warm winters and boiling summers the air conditioner will have to work double time to maintain comfort.

The difference in weather conditions from year to year will affect the costs as well. This is basically geared towards the difference in costs per year. One summer might be cooler than the next, which will lead to a greater bill.

The efficiency rating of your air conditioner plays an important role in the amount of electricity used. Most all appliances in today's world are rated, when you purchase an air conditioner it will have a tag telling you the amount of electricity that appliance uses. Look for air conditioners that use minimal electricity, which will save you money each year. If you have a model that is 10 years or older, it is definitely time to consider a new one.

Another important factor is the size of the air conditioner versus the house-cooling load. All air conditioners come in different sizes, and each will state the amount of space it is designed to cool. For example, an apartment could do with just one or two window air conditioners, while a three-bedroom house could not. Closely consider the amount of space you need to cool when considering an air conditioner. While larger air conditioners will cost more money, it will typically save you money in the long run on usage.

The setting on your thermostat greatly effects the cost. A higher setting will result in the air conditioner running less, while lowering the setting will cause it to run more often. One electric company suggests keeping the thermostat above 78 degrees. This can save you 10 to 20% on cooling costs.

Finally, the local cost of electricity influences the general cost of running your air conditioner. This is something you have no control over, however, you can control your own cost by saving energy.

Here is a general look at the difference of running an air conditioner vs. running a Ceiling or oscillating fan, at medium speed.

Running a central air conditioner that is three ton (and of average efficiency) for 8 hours per day for 15 days per month, with the average rate per kWh (kilowatt per hour) being 0.17, the average cost per month for the air conditioner alone will be $97.92. Amazing isn't it? This does not even include washer, dryer, lights, refrigerator, or stove, only the air conditioner.

On the other hand, running a ceiling fan or oscillating fan at medium speed, for 8 hours per day, for a full 30 days, at an average rate per kWh of 0.035 is only $1.43. With this comparison you could run 68 ? fans for a full month before you would reach the cost of the central air conditioning unit.

There are many other things you can do to lower you electric bill. Things such as, inspect, clean, or replace your air conditioner filters monthly. When you are not in your home, raise the temperature on your thermostat, keeping in mind pets when you do. Lower the temperature of your water heater to 120 degrees, wash only full loads in your dishwasher or clothes washer, and use the energy saving cycle on the dryer.

Other steps you can take include, replacing incandescent bulbs with fluorescent lamps, this could save up to 75% on lighting costs. You should also caulk all windows, doors, and pipes to prevent air leaks in or out, use weather stripping around windows, doors and pipes as well. Have your ducts tested for air leaks; leaking ducts can reduce the efficiency of your air conditioner by up to 20%.

HVAC Training

With strengthening modern technology, HVAC training is more necessary today than ever! While many will train for a career in HVAC (Heating, Ventilation and Air Conditioning) while on the job, more and more employers are now searching for graduates who have successfully completed their post secondary HVAC training to fill the ever-increasing demand for skilled technicians.

In an HVAC training program, students commonly learn to read blueprints; they also learn about safety issues, tools of the trade, designs, equipment construction, electronics, and the installation, maintenance and repair of heating, ventilation and air conditioning systems as well as heating and refrigeration systems. Additional coursework may include applied physics, chemistry, computer applications, electronics, and mechanical drawing.

A suitable HVAC training program is usually administered at a vocational or trade school, but there are some online HVAC schools, as well. Students are taught how to troubleshoot, repair and maintain heating, ventilation and air conditioning mechanisms and entire systems. Future HVAC technicians may evaluate settings and adjust system controls, test equipment, install fuel or water lines, and install air ducts, pumps, vent systems and other associated parts. In addition, prospective technicians learn how to connect electrical wiring and other components necessary for optimum HVAC operation.

Students who complete in HVAC training may earn a certificate or college credits. Furthermore, those who have fulfilled requirements for becoming an HVAC technician can expect a promising career outlook as the projected rate of available jobs is increasing more rapidly than many other occupations. While earnings vary, the top ten percent of HVAC technicians make more than $27 per hour.
