Who Makes Heil Air Conditioners?
Heil air conditioners are made by Heil Heating and Cooling, which operates as a brand of International Comfort Products, or ICP, a Carrier Global subsidiary.
ICP produces Heil systems alongside several other brands from the same manufacturing facilities, all sharing the same core components and engineering standards.
The ICP brand family includes Heil, Tempstar, Comfortmaker, Arcoaire, Day and Night, KeepRite, and Lincoln, each targeting different regional markets or distribution channels.
Although Heil and Carrier use different branding and distribution, ICP’s backing means Heil benefits from Carrier’s deep parts availability, technical training programs, and national service infrastructure.
ICP is headquartered in Lewisburg, Tennessee, where it manages manufacturing for its entire family of brands, as confirmed by ICP’s official brand overview.
Where Are Heil Air Conditioners Made?
Heil air conditioners are made in the United States at ICP’s manufacturing facilities, with key plants in Lewisburg, Tennessee, Norman, Oklahoma, and Texas.
The Lewisburg, Tennessee facility is ICP’s primary production hub for residential air conditioners, heat pumps, and air handlers for the North American market.
Because all ICP brands share the same production infrastructure, a Heil air conditioner rolling off the Lewisburg line is built on the same chassis, controls, and compressor platforms as systems sold under other ICP brand names.
Carrier maintains strict quality control standards across all ICP facilities, ensuring consistent performance regardless of which brand name appears on the unit.
Who Owns Heil Air Conditioners?
Heil is owned by Carrier Global Corporation through its International Comfort Products subsidiary.
Carrier acquired ICP, and with it the Heil brand, in 1999, bringing the Milwaukee-based brand into its expanding HVAC brand family.
Carrier Global became an independent publicly traded company in 2020 when it was spun off from United Technologies Corporation.
Heil’s history and ICP’s full brand portfolio are outlined in Carrier’s company history.
What Is the History of Heil?
Heil was founded in 1929 in Milwaukee, Wisconsin, originally focused on residential oil furnaces.
The brand partnered with Sears in 1957, supplying HVAC products under the Sears Kenmore name and building a broad distribution base across the United States.
Carrier acquired Heil through its purchase of ICP in 1999, integrating the brand into its expanding portfolio of residential HVAC brands at the mid and value tier.
Today Heil is a well-recognized name among HVAC contractors and competes in the mid-range market across the United States and Canada.
Heil Air Conditioners vs Carrier Air Conditioners: How Do They Compare?
Heil and Carrier are both made by Carrier Global, but serve different market positions.
Carrier premium systems sit at the top of the portfolio with the highest efficiency ratings, the most advanced variable-speed technology, and the exclusive Infinity System Control.
Heil is typically priced 15 to 25% below Carrier and offers solid mid-range efficiency through its Ion Series and Performance Series, making it accessible to a broader range of buyers.
For homeowners who want Carrier-backed engineering at a more accessible price point, Heil is one of the most direct options available through the ICP dealer network.
Are Heil Air Conditioners Any Good?
Heil air conditioners are well regarded as a reliable mid-range choice, consistently recommended by HVAC contractors for their durability and value.
The Ion Series, Heil’s premium tier, offers variable-speed inverter technology and SEER2 ratings up to 19, which is competitive with many premium brands.
One standout feature is Heil’s No Hassle Replacement limited warranty on premium models, which provides a full unit replacement if a major component such as the compressor fails within the warranty period.
Because Heil shares ICP’s parts infrastructure with other Carrier family brands, service is widely available and replacement parts are generally easy to source.
For homeowners who want a dependable, well-warranted HVAC system at a mid-range price from a manufacturer with deep American roots, Heil is a smart and well-supported option.
