HVAC, or Heating, Ventilation, and Air Conditioning is an extremely important field of work. Those who work in this field strive to ensure that the space in which we live is cool (or warm). The environments in which people work and live in are always in need of proper maintaining. Without an HVAC technician, those areas become vulnerable to outside elements. So what exactly is HVAC and what do the technicians accomplish?
What is HVAC? HVAC (Heating, Ventilation, and Air Conditioning) is the field that operates any technologies used in heating or cooling an occupied space. This could be someone's home or place of employment. It also includes businesses and places where people shop. The ultimate goal is to control the temperature inside of buildings through different channels. For example: Heating: This applies to the units used to warm a building. There are various types of heating sources, although gas is most common. But they can also be packaged into one unit with an air conditioner, known as central heat and air. Ventilation: Any air duct space throughout a building that provides airflow to every room. It is connected to heating and cooling services. Air Conditioning: The variety of air conditioning options are quite large. From packaged units to provide central heat and air, to stand alone air conditioning units, to window units. What is an HVAC System? An HVAC system is exactly as it sounds. It works behind the scenes of a building to provide the comfort of temperature and climate control. This is especially important in places where the humidity is quite high. The three most common systems include: Split and Window units: Window units use coils to cool air and dispense it into a room. The hot air that enters is retracted back out into the atmosphere. Split units work a bit differently. A cold coil is placed in what is called a "handler", or the location of where the coil will be. This is generally in a furnace. Then the air is transferred to various rooms throughout, with the coil converting it to cool. Packaged heating and cooling units: These units provide complete cooling and heating needs in one package. All the components for getting the desired temperature are in this one unit. A center fan or blower processes the air into the desired space. Central Air: The central air system may be the hardest working. Their systems are a bit more complex. Typically used in places like apartment buildings etc, they work to transfer indoor heat through the use of refrigerant. This pushes hot air out and through a coil and into the outside of the building. The air is cooled at one location and pushed into several areas throughout the building. The compressor in this option is what makes the air conditioning distribute as it should. The compressor helps push the air throughout the air ducts in the ceilings and/or fan units in a building. While these are the most common, it is important to know what type is right for the space it is being placed. That's where the technicians come in; they will know the exact needs of a building, based on square footage (how big the space is). If someone is unsure about their current air conditioning or heating set up, calling a technician may be key. They will provide insight and solutions to any HVAC related issue or concern.

Repairs are such a scary word, but in reality, it just ensures that everything is running properly. Many companies will also offer regular maintenance on units to provide consistent and safe temperature control environments. Even with that, sometimes repairs are needed. Units get old and overworked and knowing when to call the technician is crucial. Someone should call if they experience:
These are the most common issues associated with heating and cooling services. It is best to contact someone to get it looked at. Homeadvisor.com offers local searches so that customers can find technicians quickly and schedule an appointment. While the big stuff should be addressed by a licensed tech, there are some minor maintenance projects people can handle themselves. This includes changing the air filter. The world of HVAC is more than just heating and cooling; it is the safety of the environments in which we live. Having the most comfortable and consistent air quality is of utmost importance. That is why this field is one to appreciate and utilize as necessary.
