HVDC is a programmer for heating and air. The HVAC is the installer for heating and air. I have a license for both of them,
limit switch on hvac used to cut off low voltage on heating when system over heat limit
When dealing with HVAC systems, notice that there are two systems at work, and two possibilities for failure: the HVAC control system, and the actual HVAC unit. Determine if your problem is in the function of the controller (blank screen, not turning on, relay does not click on when fan or thermostat is set past current temperature), or in the HVAC unit (thermostat relay is clicking but HVAC fan does not turn on, condenser outside fan is not spinning, etc.) If the air conditioner was 'grounded', as I understand it, I would think your HVAC breaker would trip. This should help you figure out your problem.
Determine the SEER rating of the HVAC system. The SEER rating is usually provided by the manufacturer and is a measure of the system's energy efficiency. Find the total cooling capacity of the HVAC system in BTUs (British Thermal Units). This information is also typically provided by the manufacturer and can be found in the system's specifications. Plug the SEER rating and the total cooling capacity in BTUs into the formula: Tonnage = (Total Cooling Capacity in BTUs) / (SEER) For example, if you have an HVAC system with a SEER rating of 16 and a total cooling capacity of 48,000 BTUs: Tonnage = 48,000 BTUs / 16 SEER Tonnage = 3 tons

HVAC systems depend a lot on electrical motors. If you have an interest in motors, expand it to understanding electricity and electronics. Couple some math with this interest. With such a background, you will be ready for HVAC training in school or an apprenticeship program.
Most states will have a place to obtain a career in hvac. There is a place named ashworth that offers a career in hvac. Most careers in Hvac are learned in the field under qualified supervisors.
In the HVAC career field, you do not have to intern to obtain a job in this field. As an intern you gain more knowledge of your career and will help you to progress, but is not necessary if you want to advance.
No, they are all already taken. Get on the list
Many schools have bachelor's degrees in HVAC. For example, Ferris State University has a four-year program to prepare individuals for careers in HVAC.
If you look to do more with your HVAC training degree, you can do just that. By having a HVAC degree, you can seek out further opportunities in CAD related fields.
Wichita Technical Institute (WTI) is well experienced in providing HVAC certification in Wichita. It has been in this field since 1952

HVAC students typically study equipment design, construction, electronics, temperature control, maintenance & repair, and more. After training, you can expect between six months and two years of field experience--usually through an apprenticeship--before you are considered proficient in HVAC.
This depends on what country you live in. In Canada, for example, you can visit this site: http://www.trade-schools.ca/programs/hvac.asp. This is a directory of all the trade schools in Canada which have hvac training.
HVAC (Heating, Ventilation, and Air Conditioning) refers to technology of indoor or automotive environmental comfort. HVAC system design is a major subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. Refrigeration is sometimes added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped as in HACR (such as the designation of HACR-rated circuit breakers).
Typical training and college classes such as electricity and wiring are required to obtain a degree in HVAC repair; however, each school is different so it's best to check on the school itself.
