The Heil QuietComfort 12 split-system air conditioners from International Comfort Products Inc. were designed with service technicians in mind. They feature an easy access service control panel, slanted to allow the tech to see all electrical connections while standing up. The compressor compartment opens with the removal of only four screws. The discharge grill also pops off easily for inspection and cleaning.
The QuietComfort12's service valve stubs are longer (3.5 inches), protecting the valves from heat and making access easier. Only six inches of clearance are required to install the unit. Parts are standardized, meaning less parts need to be loaded on the service vehicle.
