Here are a few practical tips on how to manage your air conditioning units.

What is a rooftop unit?

A rooftop unit, as its name indicates, is a piece of equipment installed on a building’s roof which is used to ventilate, heat and/or cool commercial or industrial spaces in order to maintain optimal comfort. The main advantage of a rooftop unit is that it provides a decentralized design, which means that it is not necessary to completely shutdown the system to change the filters, for example.

The importance of rooftop unit maintenance

Inadequately heated and/or cooled buildings can cause many problems, including a loss of employee productivity and computer equipment problems. Additionally, an HVAC system’s mechanical failure can result in several thousand dollars in damages. It is therefore essential to prevent these incidents as well as many service calls by performing proper maintenance.
