Hvac OverviewHeating, ventilation and air conditioning (HVAC) controls the air temperature and quality of residential and commercial buildings. HVAC is critical both during the construction and development phase as well as afterward. It is necessary for everything from providing a comfortable work environment for laborers to keeping the curing temperature of concrete above freezing. Heating, ventilation and air conditioning machines can be powered with gas, electricity, propane, liquid propane or natural gas.
How do you know which machine is right for the job?
If HVAC is necessary on a job site, it has already been determined that a method for cooling or heating air is required. The question becomes, what is the ideal temperature, and what is the most efficient way to reach it? Heaters warm the air and air conditioners cool the air, obviously, but it is important to consider whether moving the air from a staging area -- near a door or window, for example -- into or across a building is necessary. If so, air ducts are necessary.
If neither hot nor cold air is required, ventilation is the only other possible requisite. When considering ventilated air, it is important to know if the air needs cleaning or dehumidifying. Air ducts are almost always necessary for a ventilation system.
Common Types of Hvac Equipment
Workers can combat the cold with extra clothing if heating units are not an option, but there is very little a crew of laborers can do if the temperatures become too hot. Working in temperatures that exceed 90 degrees for more than a few hours is not only uncomfortable, it can be dangerous. Air conditioners are available in two types: duct system compatible and free-standing. There are also two sizes of air conditioners: industrial and portable. Industrial air conditioners generally require a machine to move, while portable air conditioners are equipped with wheels.
Fans and Ventilators
Fans and ventilators serve the same function as electric heaters, but on the other end of the temperature spectrum. When air conditioning units are not a feasible or justifiable option, fans and ventilators are the best alternative.
Other Considerations When Renting Hvac Equipment
Indoor or Outdoor?
The most important factor to consider when renting HVAC equipment is whether it will be used inside or outside. There are heater types that cannot be used inside -- K1 heaters, for example. There are also heaters than cannot be used outside -- mostly electrical heaters that can not withstand precipitation. Air conditioning units, dehumidifiers and scrubbers are almost never used outside of a building. As such, air ducts are almost always used inside a building as well.
