Rooftop HVAC Repair & Installation

Many commercial properties use rooftop HVAC systems for heating and cooling. This type of HVAC may offer benefits. As cool air naturally moves down through the building while warm air rises, there's no need to force air downward. This saves energy. Additionally, all HVAC components are in one unit that's located outdoors, thus taking up less indoor space.


Like any other equipment, regular maintenance and repair services from a qualified, trusted commercial HVAC contractor like 1 Source Mechanical is key to a comfortable, safe indoor environment. Here's what you should know about rooftop HVAC installation and repair.

Installation Process


Rooftop HVAC installation differs from property to property, depending on factors such unit size and complexity, as well as the specific ventilation requirements and needs of the building itself. But there are a few steps common to any rooftop HVAC installation process.


First, professional HVAC technicians complete a roof evaluation. The roof must be structurally strong enough to bear the weight of the HVAC unit. In most cases, a flat roof or a slating roof — in combination with support beams — can accommodate a rooftop unit.

Technicians will determine if there's enough space on the roof to fit the HVAC equipment. There also must be enough room to allow for maintenance and repair.


Next comes analysis. A trained HVAC specialist analyzes the heating and cooling needs of the building. This information is key when deciding on the size and capacity of the HVAC system needed.


Of course, each rooftop HVAC installation situation is different, Size of the unit, system complexity, and even weather conditions all affect the length of the installation process. Generally speaking, though, most HVAC rooftop units can be installed within just a couple days.
