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.

A galvanized steel cabinet with baked-on powder coat finish provides protection against corrosion and weather hazards.

After 3 years it leaked (apparently a common problem). Replaced it with a Goodman…as I have in all our properties.

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.
