About ICP HVAC Systems
Owned by Carrier Global
ICP stands for International Comfort Products, a Carrier Global division that operates as a contractor-only distribution business. Rather than selling under the ICP name at retail, ICP runs a family of separate brands, Heil, Tempstar, Arcoaire, Comfortmaker, Keeprite, Day & Night, and Airquest, each sold through different dealer networks with different warranty packaging.
The equipment across all of those brands comes from the same manufacturing facilities. If you have an ICP-branded unit (typically found in commercial or multi-unit settings), the serial number decodes the same way as any ICP family brand: two-digit year in positions 2 and 3, manufacturing week in positions 4 and 5.

ICP HVAC Quick Facts
Warranty
ICP-branded equipment is mostly sold into commercial and multi-family channels, so warranty terms vary by project specification. Standard residential coverage is 10 years parts and 10 years compressor with registration; commercial installs may carry shorter terms negotiated at purchase.
Expected Lifespan
AC / Heat pumps: 13 to 18 years
Furnaces: 18 to 25 years
Where It's Built
Lewisburg, Tennessee (ICP's main residential plant). All ICP family brands — Heil, Tempstar, Comfortmaker, Arcoaire, Day & Night, Keeprite, Airquest, and ICP-branded — come off the same production lines.
Price Positioning
Mid-tier — ICP-branded equipment is typically priced at the contractor level rather than retail, so end-user pricing depends heavily on the install contract.
Known ICP Issues to Watch For
A short list of patterns reported on ICP equipment. Most have been addressed with revised designs or service bulletins, but they're useful context if you're diagnosing an older system.
- •ICP-branded equipment is unusual in residential settings; if you have one, it likely came from a commercial or multi-unit project and may not have the consumer-friendly warranty packaging of Heil or Tempstar.
- •All ICP-family units share the same micro-channel coil leak rates in coastal environments and the same Observer thermostat sensitivity to thermostat wiring.
- •Service parts are best sourced through any ICP-affiliated dealer (Heil, Tempstar, Comfortmaker, etc.) — they're cross-compatible across the family.
