Hvac Degrees: Heating And Cooling

The demand for heating, venting, and air conditioning professionals, commonly known as HVAC, has never declined. Well-trained HVAC professionals and graduates are skilled with the essential knowledge of system components, tools, brazing and soldering, and more. This includes the installation and troubleshooting of valves, compressors, water chillers, thermostats, heat pumps, connection switches and controls. Effective HVAC specialists are also trained to adjust refrigerant levels as well as work safely with gas, oil, and electric heat.

Among the various trades, the fastest growing branch is HVAC. It is expected to increase by 31.8% through 2012. This includes job opportunities that include working for and as building contractors, residential maintenance and service companies, plumbing supply and hardware shops, and, of course, self-employment.

Because of the sophistication of heating, air-conditioning, and refrigeration systems, employers choose to hire those who have completed technical school training or a formal apprenticeship. Some mechanics and installers, however, still learn the trade informally on the job. A number of high schools, colleges and junior colleges, and even Armed Forces branches offer programs that train prospective HVAC students. This training includes the study of temperature control, equipment construction, and electronics, as well as the basics of installation, maintenance, and repair.

There are three certified agencies that set HVAC academic standards: HVAC Excellence, National Center for Construction Education and Research, and Partnership for Air-Conditioning, Heating, and Refrigeration Accreditation. Upon completion of the academic part of the training, students typically spend another two and a half years in the field.

Apprenticeships are still very popular and practical means to gain valuable HVAC certification and training. Apprenticeship programs are often managed by local chapters of the ACCA (Air-Conditioning Contractors of America), the MCAA (Mechanical Contractors Association of America), and the PHCC (Plumbing-Heating-Cooling Contractors). Formal apprenticeships typically span three to five years and involve on-the-job training along with classroom instruction. The subjects of study include the use and care of tools and blueprints, and the theories at work with regards to heating, ventilation, air-conditioning, and refrigeration.

Students and potential apprenticeships must have a high school diploma or GED. And it should be noted that aptitudes in math and reading comprehension are crucial for successful HVAC careers. Once an apprenticeship is adequately completed, the apprentice graduates to "skilled tradesman" status and is legally certified to work alone to start his or her own company. It should be noted that some apprenticeships can qualify a student for some college credits.

An Air Conditioning Service Contracts Is Necessary For Maintenance Purposes

Experienced homeowners realize that when it comes to their air conditioning systems, prevention is always much better than the cure. Having a good quality air conditioning service plan can save homeowners from expensive repair bills for system damage that has been caused by worn and damaged components. There are many companies that offer service contracts on air conditioning units and these can provide peace of mind, as well as saving money in the long-run.

A service contract for such systems can be rather expensive in terms of the upfront cost, depending on how extensive the air conditioning system is. In most cases, the more extensive the system, the more the homeowner depends on the air conditioning equipment functioning without fail, making service contracts even more important. Many of the heating and air conditioning companies provide service contracts on the units they sell and usually have financing plans available as well.

Typical air conditioning service contracts are very comprehensive in terms of the services and parts that will be provided. The intent is to keep the air conditioning unit in good working order and to maintain the unit in order to avoid a major breakdown. Most people who have had these types of service plans for a few years have learned that they more than pay for themselves, as various equipment issues and problems come up with them.

For those who live in extremely warm climates, having an service contract is even more important because often in these areas where the temperature can climb above 90 degrees for extended periods of time, it is essential to keep the such a system always running in good condition. For homes and other facilities that have elderly residents, this is even more crucial.

The companies that sell air conditioners will typically place a higher priority on the service calls that come in from their customers who have a service contract for their heating and air conditioning equipment. Often, this means that a customer who has a service contract will have someone there to service their unit within just a few hours of reporting a problem, while other customers might have to wait for a day or two before they can expect to have someone arrive to repair their unit.

Maintaining the compressor in an such a system in also very important to prevent inefficient operation and potential damage to the equipment and to make sure the system is operating at peak efficiency at all times. Most service contracts allow for an annual maintenance check-up, in order to make sure that the unit is working well and no problems are developing. In the warmer parts of the country, it is a good idea to get a plan that allows for these check-ups on a semi-annual basis.

In all cases, the homeowner must also be sure to keep the unit free from any obstructions that might prevent the free flow of air in and out of the unit. Air conditioning service contracts can become null and void if the homeowner does not do his or her best to maintain a proper operating environment for the air conditioner.
