A system that works smarter.

Revolutionary ComfortBridge technology is factory-installed into select Goodman brand gas furnaces and air handlers to ensure that the entire system operates at peak, energy-efficient performance. Simply put, communications technology that is typically located in a thermostat was moved from the wall and securely placed into the HVAC equipment!

  • The two-stage scroll compressor runs at either 65% or 100% capacity, depending on cooling/heating demand. This operational flexibility provides a great energy-efficient option when compared to a traditional, single-stage unit.
  • The top performance of an electronically commutated motor (ECM) allows for two levels of operation depending on your airflow needs. It is a great energy-efficient option when compared to a traditional, single-speed motor.
  • Designed to regulate and communicate with your ComfortBridge™ Controls System so you can remotely monitor and manage your heating and cooling system – at any time, from anywhere with just an internet connection.
  • Filter-driers play a pivotal role in the operation of air conditioning and refrigeration systems. A factory installed filter-drier absorbs and filter''s residual system contaminants and moisture.
  • Ensures refrigerant is ready even in extreme external temperatures.
  • Prevents condensation of refrigerant in the crankcase of a compressor.
  • Reduces pass-through vibration noise from compressor operation.
  • A high-pressure switch prevents the system from operating at extremely high pressures by shutting off the compressor circuit if the pressure exceeds the designated rating. When a refrigeration system operates at lower than normal pressures, the low-pressure switch prevents freezing from working its way to the compressor.
  • High-density foam compressor blanket provides noise reduction when the compressor is in operation.
  • Consistent and concise monitoring helps to ensure that the system is operating efficiently, regardless of the weather.
  • Assists contractors in troubleshooting the system with improved diagnostic accuracy by utilizing indicator lights, seven-segment LED display, and fault code storage.
  • Time-delay defrost technology allows for a reliable, quiet, and smooth transition when units enter defrost mode.
  • By simplifying the communication connection to two low voltage wires to the outdoor unit, technicians may eliminate the need to run additional thermostat wiring.
  • Contractors can securely connect wires with large screw lugs, allowing for quick and solid wiring.
  • Proprietary, self-contained sequence of actions designed to help control system operation for energy efficient performance and enhanced reliability.
  • Fully charged with refrigerant sufficient for 15’ of tubing length to assist with easy installation of unit.
  • Meets the performance requirements for AHRI certification and complies with ETL North American safety standards.
  • A straight-forward, color-coded terminal strip for non-communicating set-up helps to simplify installation.
  • Copper coil tubing with enhanced aluminum fins increases the area for heat absorption, providing outstanding, energy-efficient heat transfer performance.
