A Few Words On Central Air Conditioners

Although there are quite a few variants of air conditioners available in the market today, it is being observed that the central air conditioners are increasingly gaining popularity even for domestic purposes. It is a fact, that the central air conditioners have ruled the roost as far as commercial air conditioning goes. Now that they are making inroads in the domestic market also is significant.

Besides the general effects of air conditioners of keeping you cool and comfortable, central air conditioners have also been positioned by their manufacturers as partial air filters and dehumidifiers. Now if someone in your family has minor problems of allergy or asthma, then installing a central air conditioner can be of help.

Before you get yourself a central air conditioner installed in your house, you need to know exactly what capacity of air conditioner you will require. With other kinds of room air conditioners, knowing the dimensions of the rooms can be good enough. However, since the central air conditioner will be for the entire house, calculating the capacity of air conditioner you will require should be best left to an expert. You can call a contractor and take inputs from him. Any contractor would use , what we call the ?manual j? method to determine the size of the air conditioner you will require for your house.

When you actually shop for a central air conditioner you should consider two ratios, the Seasonal Energy Efficiency Ratio (SEER) and the Energy Efficiency Ratio (EER). These ratios will tell you how efficient your air conditioner really is. Since most modern air conditioners come with SEER ratio higher than 13, you should settle nothing less than that. Even the EER ratio should be around 12.

There are still a few negatives to the central air conditioning system. First of the installation is costly and it is also a lot of hassle. There need to be provision for installing a central air conditioner, the network of ducts has to be perfect so that all the areas in the different rooms are evenly cooled. The central air conditioner is also much less energy efficient than the room air conditioners. It cools the entire house even though all the residents of the house are in a single room.

So think before investing on a central air conditioner and weigh your options. If you find it is a worthwhile investment then go ahead and get yourself one.

Air Conditioner Installation

Air conditioners have become an essential part of many households and there are a variety of air conditioners available on the market for different prices, serving different purposes and under different brand names. Buying an AC is not at all difficult, owing to the many companies selling them these days. The tougher task is the installation once the unit has been purchased.

Correct installation is very important, as it has quite a bearing on the actual effect of the air conditioner. Incorrect installation can lead to high electricity bills, poor cooling air circulation, as well as maintenance problems. Many studies have proven that air conditioners that are improperly installed reduce its capacity and efficiency by more than twenty percent. Incorrect airflow problems are another common problem with improper AC installations. In fact, appropriate air conditioner installation is one of the four elements needed to maintain an economical, efficient and comfortable cooling system.

There are four things that one must keep in mind while installing the air conditioner. First, it is important that the airflow over the fan coil unit goes through the forced air duct system in the air handler. Secondly, the refrigerant charge must be at a proper level. Third, the outdoor air supply unit must be fixed in the right place. Finally, the control system, especially the thermostat that turns the equipment on and off, must be at a hands reach. These general installation guidelines are applicable to all installations. Air conditioners come with an installation guide that should be read thoroughly and can prove to be quite an asset.

However, these days almost all companies offer to send a technician to your home or business to install the air conditioner, and it is advisable to allow an installation professional handle the work.

Central Air Conditioners

When buying new central air conditioning equipment, it is very important to have the work done by a qualified contractor. Most review sites and available information say that the best way to save money on a central conditioning unit is by hiring a good contractor. This is followed in close second by picking an energy efficient system. A proper installation of a central air conditioner will ensure that the unit is tightly sealed and no energy is wasted thought leaky ducts thus saving as much money as possible.

When speaking of saving money through efficient air conditioning systems the topic of SEER usually comes up.Central air conditioners are rated by something called SEER or seasonal energy efficiency ratio. Without going into details, the higher the SEER the more efficient your central conditioning system is thus saving you money and helping the environment through less power demand.

Most central air cooling systems run on Freon and have for many years but this is apparently going to change. Freon will be replaced by a newer refrigerant called Puron that is friendlier to the environment no later than 2010. The good news about this is that although Puron powered central air conditioners may cost more initially, the Freon machines and parts are going to get scarce. Getting scarce parts for your conditioning unit will cost you as all the older machines start to break down and need repairs, but parts are harder to find.

Speaking of costs, this is the one glaring down point of a central cooling system. While cost may not be an issue for some, the central air conditioner unit is the most expensive way to cool your house on the initial investment. Because the conditioning unit must be installed and venting systems run, you will have to hire a contractor. Therefore part of the cost of getting a central cooling system will depend the flexible pricing of the local contractor. With the unit air conditioning systems this is not an issue, but again with the unit systems you can only cool one room at a time and they could be a bit of an eye sore in a posh setting.

Students learn to troubleshoot the electronic and mechanical components of HVAC units.

HVAC Schools offer numerous options to earn diplomas, certificates, and Associate of Applied Science (AAS) degrees. Diploma and certificate programs can be completed in a year or 18 months; AAS degree programs can be completed in two years and involve more in-depth study of management and business applications.

Training will include commercial heating, refrigeration and air conditioning, wiring techniques, service call procedures, and troubleshooting training programs and courses. Graduates of HVAC Schools are prepared for positions working with heating, refrigeration, and air conditioning systems as entry-level technicians, mechanics, and service sales persons.

Some HVAC Schools offer two-year Associate of Applied Science degree programs in service management. Students in AAS service management degree program will concentrate on business operations - accounting, business law, salesmanship, and management - and aspects of customer service. AAS service management graduates are prepared for positions as repair technicians, apprentice mechanics, supervisors, and managers at the entry-level.

HVAC technicians may work in various types of businesses and manufacturing, for private contractors, or in institutional buildings. There is a steady demand for skilled HVAC technicians. Even though the work can be strenuous at times, the rewards can be worth it, with most technicians bringing home respectible salaries.

If you are interested in the field of heating, ventilation, air conditioning, and refrigeration, apply to a HVAC School or Online HVAC School today!
