The Heil N4A3 is a single-stage central air conditioner with an efficiency rating of 13 SEER. A filter drier protects the system from moisture and debris, and the unit’s top-discharge design improves airflow while reducing operating noise levels to as low as 74 decibels. The control panel is easily accessible for quicker serviceability, and the unit is compatible with most cooling thermostats. A galvanized steel cabinet with baked-on powder coat finish provides protection against corrosion and weather hazards.
A homeowner on hvac-talk.com asked for opinions between a Heil system, including the N4A3, and a Trane system. A member noted that the N4A3 is a builder model and that Heil units are very similar to Carrier. In another post on the same site asking for opinions on several units, it is again noted by a member that the N4A3 is a builder model. There is also a post on central-air-conditioner-and-refrigeration.com from a homeowner who is very pleased with his N4A3. An installer replied that he installs about 4 Heil AC units per week and never has a problem.
