Leaky units, moldy walls, and dangerous, clogged pipe runs leaking condensate water over electrical outlets. With demand for air conditioning hitting 6.77 million units in Latin America in 2017, incorrect sizing of air conditioning units is no joke. Americans use 6 percent of all electricity produced in cooling their buildings, and the cost of running central air conditioning can easily come to thousands of dollars a year. Incorrect assessment of buildings' cooling requirements often results in wrong unit sizing and unnecessary costs for the client by paying for a system that is over/under specified.
The environment also plays a factor in the type of air conditioning that is specified — whether a whole building approach is needed or cooling and heating is needed on a room by room basis. With more people in arid climates moving to wall mounted units for better efficiency and cost control, it is becoming increasingly important to ensure that the right type of unit is specified, and also that installation methods used are in line with the type of unit installed, ultimately saving money and time.
