While most people will not require any form of HVAC, some people do, and it can be a good idea to have an HVAC system. Before you choose which HVAC system will work best for you, make sure you know a little bit about the basics of HVAC systems.
Systems vary in terms of the type of system that is installed. The most common ones are the wall and ceiling mounted types. These are usually called ambient or recirculation systems. They work by circulating the air inside the building through ducts through the walls of the building and into the rooms, offices, or other enclosed spaces.
The open ventless type of system uses an air pump to move the air and distribute it throughout the room, not by ducting. This can either be a wall-mounted unit or a ceiling-mounted unit.
There are also portable HVAC systems. Portable systems use power instead of ducts and can be moved from one location to another or used to supply cold air to other rooms in the building.
There are also attic vents systems. They are similar to the open ventless type of system, but they are mounted higher on the attic rafters than in an open ventless system. Their main function is to circulate warm air from the attic, up to the roof, where it enters the conditioned space below the roof.
Indoor systems are better suited for providing heating, cooling, and cleaning, and for some types of jobs, better than outside systems. When choosing a system for use in an office, look at the overall climate and atmosphere that are present in the room or office. Make sure the unit is rated for the intended use so that in case of an accident or leak, the system will still operate.
Measure the area of the room or office that will be serviced to determine if an indoor or outdoor system will be needed. Also, consider how many people will be using the room.
Determine how often the rooms or offices will need to be cleaned. If your entire building will need to be air-conditioned, then you may want to have a system that can handle all that cooling and circulation.
Certain types of jobs demand a more complex set of equipment than others. For example, you will probably want to have a simple, one-man system when doing work where only one person will be working or when hiring a new employee.
One of the most important decisions you will have to make is that HVAC systems will provide the heat or cooling and circulation you need, depending on the job you are doing and the needs of the room. Remember that if you don't have proper ventilation, you will end up with dust in the air, and this could possibly affect the workers, the environment, and your neighbors. So it is really important to have a system that provides air for optimum efficiency.
Making a decision on the right HVAC system for your home can be confusing, but should not be nearly as difficult as it can be if you understand the basic function of the systems you are considering. Don't forget to consider how much money you will be spending to purchase it, the type of room that will be used in, and how often you will be using it.
