In 1992, a non-governmental organization, Greenpeace, was spurred by corporate executive policies and requested that a European lab find substitute refrigerants. This led to two alternatives, one a blend of propane (R290) and isobutane (R600a), and one of pure isobutane. Industry resisted change in Europe until 1993, and in the U.S. until 2011, despite some supportive steps in 2004 and 2008 (see Refrigerant Development above).
Although HVAC is executed in individual buildings or other enclosed spaces (like NORAD's underground headquarters), the equipment involved is in some cases an extension of a larger district heating (DH) or district cooling (DC) network, or a combined DHC network. In such cases, the operating and maintenance aspects are simplified and metering becomes necessary to bill for the energy that is consumed, and in some cases energy that is returned to the larger system. For example, at a given time one building may be utilizing chilled water for air conditioning and the warm water it returns may be used in another building for heating, or for the overall heating-portion of the DHC network (likely with energy added to boost the temperature).
Multiple inventions within this time frame preceded the beginnings of first comfort air conditioning system, which was designed in 1902 by Alfred Wolff (Cooper, 2003) for the New York Stock Exchange, while Willis Carrier equipped the Sacketts-Wilhems Printing Company with the process AC unit the same year. Coyne College was the first school to offer HVAC training in 1899.
Advantages of the ductless system include smaller size and flexibility for zoning or heating and cooling individual rooms. The inside wall space required is significantly reduced. Also, the compressor and heat exchanger can be located farther away from the inside space, rather than merely on the other side of the same unit as in a PTAC or window air conditioner. Flexible exterior hoses lead from the outside unit to the interior one(s); these are often enclosed with metal to look like common drainpipes from the roof. In addition, ductless systems offer higher efficiency, reaching above 30 SEER.
The changing seasons take a toll on your HVAC equipment. Unfortunately, it always seems that your aging furnace gives up in the middle of a cold snap and your AC unit sputters out during the hottest day of summer. These events are more than an annoyance: they can quickly turn into emergencies when your home reaches extreme temperatures. That's when it's time to call in your local ARS®/Rescue Rooter® HVAC specialist, who has the training to get to the root of any heating, ventilation or air conditioning problem quickly.

Called a few different places and they were the only ones that called back. The technician Tony came out and after a little testing said the main control board needed to be replaced. He quoted us a total of $489 which seemed on the high side but it was cold and we were somewhat desperate, so we agreed and paid a parts deposit.
A heating, ventilation and air conditioning (HVAC) service technician starts an appointment with a customer by asking about any problems with the heating, ventilation, and/or air conditioning systems in the client's home or business. From there, the technician will carefully examine the equipment in question to diagnose and troubleshoot the problem. Once the issue is determined, the technician provides the customer with a repair quote and, if authorized, begins to repair or replace defective equipment, mechanical components, or wiring in HVAC systems. An HVAC service technician might also be called upon by a customer to carry out preventative maintenance tasks or inspections to ensure that heating, ventilation, and air conditioning systems continue to run smoothly. A technician should have certification or an associate's degree from a technical or trade school that is accredited by HVAC Excellence, the National Center for Construction Education and Research, or the Partnership for Air Conditioning, Heating, and Refrigeration Accreditation. Formal training programs can last anywhere from six months up to two years. The job involves working with electrical equipment, so it is very important that a technician know exactly what he or she is doing or the job can get very dangerous very quickly. If an education is not in the picture, it is sometimes possible to go through a formal apprenticeship program which can take three to five years and mixes on-the-job experience and training with classroom instruction. Exams for certifications are offered by a number of associations. A license to work as an HVAC technician is required in several states and can be obtained by passing a written test.

6) Check your ductwork and seal open spaces. Make sure all your doors and windows are properly sealed to help keep your home cool. Perform a visual inspection of your ductwork occasionally to be sure it is sealed correctly. If ductwork is not properly sealed, cool air will escape before getting into your home. The less cool air that escapes your home, the less your unit will have to work.
A contactor is a $25 mechanical relay that uses low-voltage power from the thermostat to switch 220-volt high-amperage current to the compressor and condenser fan. AC contactors can wear out and are at the top of the list of common air conditioning service failures. Even if your contactor is working, it pays to replace it every five years or so. Unscrew the old contactor before removing the wires. Then move the wires to the new unit (photo 6).
