FAQs: Rooftop HVAC Unit Services

A rooftop unit, like the name implies, is a packaged unit installed on the roof. These packaged units contain all air conditioning components, including:

Evaporator coil
Fan
Compressor
Condenser

They also can be slab-mounted on the ground and have heating capabilities, depending on the particular model. Unlike split systems commonly used in residential properties, packaged units don’t separate the evaporator coil and fan from the compressor and condenser.

Getting the Heat Out

Once a rooftop AC unit is installed, cool, low-pressure refrigerant arrives at the compressor as a gas and then compresses into a hot, high-pressure gas as it flows into the condenser coil. There, the metal fins on the coil absorb and disperse the heat, and the condenser fan blows the exhaust away from the building.

As warm return air travels through the ductwork into the rooftop unit, fresh air enters as well for ventilation. Positioned over the return air duct are air filters to prevent contaminants from landing on the sensitive cooling equipment.

The Refrigerant Cycle

Now that you understand how a packaged unit gets the heat out, below we’ve listed the steps in the refrigerant cycle:

The now-cooled liquid refrigerant passes through the evaporator coil.
As the pressure drops, the liquid converts back to a gas.
As warm air from the building passes over the evaporator coil, the refrigerant extracts heat from the air.
The evaporator fan returns the ice-cold air back into the building.
The warmed refrigerant (having absorbed the heat) circulates back to the compressor to release its heat through the exhaust system.
And the cycle repeats again and again until your building’s temperature reaches the thermostat setting.

Rooftop Units That Can Heat

Rooftop units that also provide heating often contain a gas heat exchanger downstream from the evaporator fan. In heating mode, return air is discharged into the heater and blows over gas-fired coils. A fan then sends newly heated supply air back into the building.

Rooftop units have a few advantages over split systems that you might want to consider when choosing your new AC system. Rooftop units:

Are quieter inside your building
Save space
Can undergo maintenance in one place
Are easier to install

AHU stands for Air Handling Unit while RTU is an acronym for Rooftop Unit. An RTU is a type of AHU and as such is there any difference between the twoAHU vs RT? There are no differences between an AHU and an RTU except for the fact that an RTU is placed on the rooftop.

The Air Handling Unit is a huge metal box, which helps in conditioning and circulating the air to create an ideal atmosphere. The AHU consists of components such as heating elements, cooling elements, blower or fan, filters, mixing chambers, vibration isolators, humidifiers, heat recovery devices and controls. All these components are also present in an RTU as it is only a type of AHU. Three types of AHUs are available in the market. The Mall Air Handlers and Make Up Air Units are the other two types of AHU.

The Roof Top Unit is an outdoor AHU. As the RTU is mounted on the roof, this removes the concern about creating extra space or room for fitting it as is the case for the other types of AHU. As the Unit is fitted on the rooftop, one should have more care as it is exposed to the weather. The RTU box is made of aluminum sheets or galvanized steel with a coating of corrosion resistance materials. All the components like the fan, motor, damper actuator linkages, water valves and controls are installed inside the box.

Both the RTU and the AHU function in the same manner. They sucks air from the room and pass it through cooling coils. After this the cold air is discharged into the room. The moisture in the air is condensed as it passes through the cooling coils.

Rooftop HVAC systems can have a long operating life—15 to 20 years or more is not unusual. Fullerton from Trane points out, “There is no substitute for a strong preventive maintenance program. This can help avoid emergency replacement situations.” Even if your rooftops are well-maintained and still operating, it might be useful to have an energy analysis performed by a qualified contractor. As Fullerton points out, “Then a proactive decision can be made whether to replace the unit based on energy savings, or to wait until a major component fails. Fixing on failure often limits the potential savings of a replacement unit, since availability of a new unit tends to drive the decision process.”

A valuable function in rooftop units is the so-called economizer function. This is the capability of using filtered outdoor air for cooling in lieu of running the compressor, thus saving significant energy. Economizer systems test both the temperature and humidity of the outdoor air to ensure it is cool enough and dry enough to meet building comfort standards. The economizer function is used in many areas during the “shoulder” months when temperatures and humidity levels are both moderate. Use of economizer cooling is a priority in many new building efficiency standards.
