Islandaire EZ Series HQ is a replacement for the Heil Quaker models of SEA and SHA units. Our commercial duty construction with heavy gauge galvanized steel and superior components create an efficient reliable unit. This design eliminates the need for any interior or exterior renovation. Use of the existing wall sleeve-cabinet and louver saves time and money, two very important factors in today’s competitive environment!​​​ ​
