Heil Product Lines

Ion Series (Premium Tier)

The Heil Ion Series is the premium tier of Heil heating and cooling equipment, featuring two-stage or variable-capacity operation, advanced Wi-Fi-enabled smart thermostat compatibility, and SEER ratings reaching the high-efficiency range for air conditioning. Ion Series gas furnaces use modulating or two-stage gas valve technology for precise heating output control, reducing temperature swings compared to single-stage equipment. Ion Series air conditioners and heat pumps operate at high efficiency levels while maintaining quiet operation through advanced compressor technology. Ion Series equipment is specified for applications where maximum efficiency, smart home integration, and the lowest operating sound levels are the primary specifying criteria. The Ion System Control connects Ion Series equipment to Wi-Fi for remote monitoring and control through a smartphone application.

QuietComfort Series (Mid-Tier)

The Heil QuietComfort Series represents the mid-tier of Heil heating and cooling equipment, designed for reliable, quiet operation in residential applications where premium features of the Ion Series are not required but single-stage entry-level equipment does not meet the installation or specification. QuietComfort Series equipment is available in gas furnace, air conditioner, and heat pump configurations suited to standard residential load calculations. QuietComfort Series products provide the reliability and parts availability of the Heil brand at a mid-market price point. Where the Ion Series targets maximum efficiency and smart home connectivity, the QuietComfort Series targets consistent, quiet performance for standard residential applications.

Performance Series (Standard Tier)

The Heil Performance Series is the standard-efficiency tier of Heil heating and cooling equipment, designed for residential new construction and replacement applications where standard efficiency meets local code requirements and the installation budget does not call for premium-tier equipment. Performance Series gas furnaces operate at 80% AFUE, the minimum efficiency level for gas furnaces in most U.S. climate zones. Performance Series air conditioners and heat pumps operate at SEER ratings that meet minimum federal efficiency standards. Performance Series equipment provides the breadth of the Heil product line at a cost-effective entry point, backed by the same ICP manufacturing infrastructure and parts availability as the premium tiers.

Air Handlers and Coils

Heil air handlers and evaporator coils are matched system components designed to pair with Heil outdoor condensing units for split-system air conditioning and heat pump applications. Matched system combinations from Heil are AHRI-certified, providing the efficiency ratings required for equipment permit and rebate documentation. Heil air handlers are available in upflow, downflow, and horizontal configurations to match the installation orientation at the air handler location. Where a Heil condensing unit requires an indoor coil component, Heil air handlers and evaporator coils provide the factory-matched indoor unit with documented AHRI system ratings.

Why Contractors Specify Heil

HVAC contractors specify Heil because the brand is part of International Comfort Products, which has manufactured heating and cooling equipment for more than 70 years in U.S. and international facilities, providing a long-established parts availability chain for in-service equipment. Heil products span three distinct efficiency tiers, allowing contractors to specify the right product for the installation budget and local efficiency code requirement without switching manufacturers. Ion Series equipment carries AHRI certification on matched system combinations, providing the certified efficiency documentation required for utility rebate applications in jurisdictions where high-efficiency equipment incentives are available. Heil gas furnaces include limited lifetime heat exchanger warranties on qualifying products, covering the highest-cost component in a gas furnace over the life of the installation. Heil products are available through SupplyHouse and authorized Heil distributors.

How to Choose a Heil Product

The primary selection variable for a Heil product is application type. Gas furnace applications call for a Heil gas furnace in the appropriate AFUE tier (80% for standard efficiency, 90%+ for high efficiency). Air conditioning applications call for a Heil air conditioner matched to an indoor coil or air handler. Heat pump applications call for a Heil heat pump outdoor unit paired with an indoor air handler. Confirm the system type (gas/electric, split-system or package) before selecting the Heil product family.

The second variable is efficiency tier. Which Heil series is right for the installation depends on the local efficiency code minimum, available utility rebates, and the installation budget. The Heil Performance Series meets standard minimum efficiency requirements. The QuietComfort Series provides a mid-efficiency upgrade with quieter operation. The Ion Series provides the highest efficiency and smart home connectivity. Confirm the SEER2 and AFUE minimums for the installation jurisdiction before selecting a Heil series.

The third variable is system matching. Heil split-system components (outdoor unit plus indoor coil or air handler) must be matched to achieve AHRI-certified efficiency ratings. For warranty and rebate documentation purposes, use the AHRI directory to confirm the rated system efficiency for the specific Heil outdoor unit and indoor coil combination selected for the installation. Consult Heil engineering documentation for how to size a Heil furnace or air conditioner for the calculated heating or cooling load.
