Customer Questions
What is a Commercial Gas Packaged Unit?
A commercial packaged gas/electric unit is an all-in-one HVAC system that contains the air conditioner, gas furnace, evaporator coil, condenser, compressor, and controls inside a single cabinet. Unlike split systems, everything is housed in one outdoor unit, typically installed on a roof or concrete pad. This simplifies installation and frees up indoor space.

What types of buildings use Rooftop Gas Packaged Units?
Commercial Gas Package Units are commonly used for: Retail Stores Restaurants Churches Warehouses Office Buildings Schools Light Industrial Facilities Most Gas Package Units can be used on a rooftop or at ground level
Read More
How does a Commercial Gas Packaged Unit work?
Commercial Gas Packaged Unit uses two separate heating and cooling methods: Cooling Mode The electric air conditioning system removes heat from the building. A scroll compressor circulates refrigerant to provide cooling. Heating Mode Natural gas is burned inside the furnace section. Heated air is distributed through the ductwork. Your Commercial Gas Packaged Unit will automatically switch between heating and cooling based on thermostat demand
Read More
What is the life expectancy of the typical Commercial Gas Packaged Rooftop Unit?
The typical life expectancy of a Commercial Gas Rooftop Packaged Unit is approximately 15–20 years with proper installation and routine preventative maintenance. Factors such as operating hours, weather exposure, maintenance frequency, and overall operating conditions can affect equipment longevity. Regular filter changes, coil cleaning, inspections, and servicing of burners and heat exchangers can help extend the unit's lifespan.
Read More
Can a Commercial Gas Packaged Unit provide suitable year-round operation?
Yes. A commercial gas packaged unit provides year-round heating and cooling by combining a gas furnace for heating with an electric air conditioner for cooling in one self-contained system. During colder months, the gas furnace provides reliable heat, while the cooling components operate during warmer months to maintain comfortable indoor temperatures. This makes gas packaged units a versatile HVAC solution for commercial buildings that require heating and cooling throughout the year.
Read More
What does BTU and Tonnage Mean?
BTU (British Thermal Unit) measures the amount of heating or cooling energy a commercial rooftop packaged unit can produce per hour, while tonnage measures the unit's nominal cooling capacity. One ton of cooling equals 12,000 BTU/h, meaning a 10-ton commercial rooftop unit provides approximately 120,000 BTU/h of cooling capacity. Both measurements help contractors and customers determine the appropriate HVAC system size and output for a building's heating and cooling requirements.
Read More
What accessories or additional components are needed to install a Commercial Rooftop Units?
Installing a commercial rooftop unit may require several accessories and additional components depending on the building's existing setup and installation requirements. Common components include a roof curb or curb adapter, ductwork transitions, electrical disconnects, thermostats, economizers, dampers, and supplemental heating kits when applicable. Additional accessories, such as hail guards, smoke detectors, and condensate drain components, may also be recommended based on the application. Always verify equipment compatibility and manufacturer installation requirements before purchasing additional components.
Read More
Can I replace my existing Commercial Rooftop Unit without replacing the ductwork?
Yes. In many cases, an existing commercial rooftop unit can be replaced without replacing the current ductwork, provided the duct system is in good condition and compatible with the new equipment. Before installation, an HVAC professional should evaluate the ductwork, airflow requirements, unit capacity, and existing connections to ensure proper system performance. Additional modifications may be necessary if the new unit has different dimensions, airflow configurations, or connection requirements.
Read More
What is the difference between EER and IEER ratings on Commercial Rooftop Units?
EER (Energy Efficiency Ratio) and IEER (Integrated Energy Efficiency Ratio) are ratings used to measure the cooling efficiency of commercial HVAC equipment. EER measures how efficiently a unit operates under specific full-load outdoor temperature and operating conditions, while IEER evaluates efficiency across multiple operating conditions, including part-load performance. IEER provides a broader picture of how efficiently a commercial rooftop unit operates under varying cooling demands throughout the year. Higher EER and IEER ratings generally indicate greater energy efficiency and potentially lower operating costs.
Read More
Can a Commercial Rooftop Unit be installed on the ground instead of the roof?
Yes. Some commercial packaged rooftop units can be installed at ground level when the equipment is designed for horizontal airflow rather than vertical rooftop discharge. These horizontal-flow units require adequate space, a stable mounting surface, proper ductwork connections, and sufficient clearance for airflow and servicing. Always verify the manufacturer's installation requirements and local building codes before selecting a ground-level installation.
Read More
Do Commercial Rooftop Units require professional installation?
Yes. Commercial rooftop units should be installed by qualified HVAC professionals to ensure proper equipment placement, electrical connections, ductwork compatibility, refrigerant handling, and system performance. Professional installation helps ensure the unit operates safely and efficiently while meeting applicable building codes, manufacturer requirements, and local regulations.
