Bosch HVAC

Bosch HVAC main picture

Bosch Home Comfort brings over a century of German engineering heritage into the U.S. HVAC market. Known worldwide for precision and efficiency, Bosch has carved a niche in residential HVAC by focusing on inverter-driven comfort solutions and compact designs. In the U.S., Bosch offers both traditional gas furnaces and advanced ductless heat pump systems, giving homeowners flexible options depending on their climate and home setup.

For this review, I’ll focus on the Bosch BGH96 Gas Furnace, which offers high-efficiency heating with a quiet, dependable design, and the Bosch Climate 5000 Ductless Mini-Split Heat Pump/AC, which showcases Bosch’s strength in inverter-driven, variable-capacity technology. Together, they highlight Bosch’s dual focus: combining American-style furnaces with global expertise in ductless and heat pump technology.

Heil HVAC

Heil HVAC main picture

Heil may not be the first HVAC brand homeowners think of, but industry insiders know it as part of ICP (International Comfort Products)—the same corporate family that builds Carrier and Bryant systems. This means Heil equipment often shares the same engineering DNA as its premium siblings, but is marketed at a slightly lower price point with fewer flashy brand campaigns.

For this review, I’ll focus on Heil’s flagship Ion™ series: the Ion 98 G97CMN Furnace, the Ion 21 Variable-Speed Air Conditioner, and the Ion Variable-Speed Heat Pump HVH8. Together, these represent Heil’s top technology tier, blending high efficiency, modulating or inverter-driven performance, and smart connectivity. In my experience, Heil appeals to homeowners who want near-premium comfort without paying Carrier Infinity pricing.
