Your Bryant Packaged Heat Pump rooftop unit (RTU) was designed by customers for customers. With no-strip screw collars, handled access panels, and more we’ve made your unit easy to install, easy to maintain and easy to use.

Easy to install:

All Legacy Linet units are field-convertible to horizontal air flow; no special adapter curbs or kits are necessary. Convertible airflow design makes it easy to adjust to unexpected job-site complications. Lighter units make easy replacement. Bryant 3-8.5 ton 548J rooftops fit on existing Bryant curbs dating back to 1989. Also, our large control box gives you room to work and room to mount Bryant accessory controls.

Easy to maintain:

Easy access handles by Bryant provide quick and easy access to all normally serviced components. Our “no-strip” screw system has superior holding power and guides screws into position while preventing the screw from stripping the unit’s metal. Take accurate pressure readings by reading condenser pressure with panels on. Simply remove the black, composite plug, route your gauge line(s) through the hole, and connect them to the refrigeration service valve(s). Now, you can take refrigeration system pressure readings without affecting the condenser airflow.

Easy to use:

The newly designed, master terminal board by Bryant puts all your connections and troubleshooting points in one convenient place, standard. Most low voltage connections are made to the same board and make it easy to find what you’re looking for and easy to access it. Bryant rooftops have high and low pressure switches, a filter drier, and 2” (51mm) filters standard.

548J specifications

The Bryant 548J is a high-efficiency gas furnace that combines advanced features and technologies to provide exceptional heating performance. Designed for residential applications, the furnace is notable for its ability to deliver consistent warmth while ensuring energy efficiency and reliability.

One of the main features of the Bryant 548J is its ultra-high efficiency rating, which allows homeowners to save significantly on energy costs. With an Annual Fuel Utilization Efficiency (AFUE) rating of up to 96.5%, this furnace is designed to convert a large portion of fuel into usable heat. This is a remarkable characteristic that not only reduces utility bills but also contributes to a lower environmental footprint.

The 548J is equipped with a modulating gas valve and a variable-speed blower motor. The modulating gas valve enables the furnace to adjust its heating output based on real-time temperature demands, ensuring a more precise heating experience. This results in reduced temperature fluctuations within the home, providing a comfortable living environment. The variable-speed blower motor works in tandem with the modulating valve, facilitating improved air circulation and efficient temperature control.

Additionally, the Bryant 548J features a durable and compact design, making it suitable for various installation spaces. Its quality construction ensures longevity, while the optional stainless steel heat exchanger enhances its reliability. The furnace also includes a quiet operation mode, which minimizes noise levels, ensuring that the unit works quietly in the background without disturbing the household's peace.

Integration with smart home technology is another advantage of the Bryant 548J. Homeowners have the option to connect the furnace to a Wi-Fi-enabled thermostat, allowing for remote temperature control and monitoring. This feature offers enhanced convenience and the ability to optimize energy use according to a homeowner’s schedule.

For peace of mind, the Bryant 548J comes with a range of warranties, protecting the consumer's investment.
