Gas Pack Options

Packaged Gas Heating and Electric Cooling Systems

Standard Gas Packs

Packaged gas heat and electric cooling in one outdoor cabinet for dependable residential comfort.

High-Efficiency Gas Packs

Upgraded efficiency options can reduce energy use compared with older or failing equipment.

Two-Stage Gas Packs

Two-stage operation can improve comfort, reduce temperature swings and lower operating sound.

How Gas Packs Work

A gas pack combines a gas furnace section, electric cooling system and blower assembly in one outdoor cabinet. Conditioned air is delivered through a central duct system.

Safety matters: Gas pressure, combustion, venting, temperature rise and electrical operation must be tested during installation and service.

Major Components

  • Gas furnace section and heat exchanger
  • Compressor and refrigerant coils
  • Blower assembly and controls
  • Supply and return duct connections

Why Choose a Gas Pack?

All-in-One Outdoor System

Heating and cooling components are combined in one weather-resistant cabinet.

Indoor Space Savings

A gas pack can reduce the need for a separate indoor furnace or air handler.

Strong Gas Heating

Natural-gas or propane heat can provide reliable cold-weather comfort.

Central Cooling

The same packaged system provides air conditioning during warm weather.

Simplified Replacement

Compatible properties can replace an older packaged unit without redesigning the entire HVAC layout.

Flexible Efficiency Options

Single-stage, two-stage and variable-speed models are available.

Smart Thermostat Compatibility

Compatible controls can manage schedules, staging and alerts.

Residential and Commercial Use

Gas packs can serve qualifying homes and light-commercial buildings.

Signs Your Gas Pack Needs Attention

No Heating or Cooling

Electrical, ignition, refrigerant, blower or control problems may stop operation.

Frequent Cycling

Sizing, airflow, thermostat or safety issues can cause short cycling.

Higher Utility Bills

Dirty components, duct leakage or declining efficiency can increase gas and electric use.

Uneven Comfort

Airflow, ductwork or equipment problems may create hot and cold areas.

Unusual Noises

Rattling, squealing, grinding or ignition sounds require professional diagnosis.

Repeated Limit Trips

Restricted airflow or overheating can trigger safety controls.

Water Around the Unit

Drainage problems or coil icing can lead to water leakage.

Aging Major Components

An older compressor, heat exchanger or blower may justify replacement.
