Rooftop Commercial Services

Packaged rooftop heating and air conditioning systems are the most common HVAC systems for commercial buildings. A rooftop unit contains all the same components found in a residential forced air heating and cooling system such as the: Compressor, Evaporator coil, Condenser, Heating unit, Supply fan, Exhaust fan and Filter.

A wide number of sizes and rooftop unit designs are available that are found on the rooftops of most of our regional office buildings, retail stores, malls, schools, manufacturing plants and a host of other commercial facilities. Single rooftop units can cover all the heating and cooling needs of a facility, or they can be configured to manage only cooling. The major advantages of rooftop units are their simplicity and relatively low installation and maintenance costs.


Routinely scheduled maintenance of rooftop units and multi-split systems is the key to their longevity, performance and ability to deliver proper indoor air quality. Unfortunately, commercial heating and air conditioning systems are often “out-of-sight, out-of-mind” and completely neglected to a point where the unit is no longer providing adequate comfort for your employees and customers. It is very important that you schedule preventative maintenance to maximize the lifespan of your commercial system.

Commercial Multi-Split Systems

Commercial heating and air conditioning split systems consist of two key parts: the outdoor unit and the indoor units. The outdoor unit is installed on or near the wall outside of the room or space that you wish to cool. This unit houses the compressor, condenser coil and the expansion coil or capillary tubing. The indoor unit contains the cooling coil, a long blower and an air filter. Heating and Cooling split systems do not require much installation time because these systems do not require ductwork. The indoor and outdoor units are connected with a set of electrical wires and tubing, which is beneficial both for your wallet and the environment.

Commercial heating & cooling split systems offer a variety of advantages to your business operations. The most obvious benefit of split systems is their quiet performance, which is because the compressor and fan for the condenser are located outside of the room being cooled. No component of your business operations will be disrupted due to noise with heating and cooling split systems. Also, you can expand a split system for a multi-split system, where you can have more than one indoor unit connected to a single outdoor unit. This makes it very easy to cool multiple rooms in a large commercial facility. Additionally, a split air conditioner is an efficient and highly cost-effective way to cool your business.
