Help with size, SEER2 and measuring
Size. It is in the model number on your current unit’s label: 018 is 1.5 tons, 024 is 2, 030 is 2.5, 036 is 3, 042 is 3.5, 048 is 4 and 060 is 5.
SEER2. The cooling efficiency rating. A higher number uses less electricity for the same cooling. Each choice shows only systems in that range, for example 14 SEER2 covers ratings below 15.
Fit. The indoor unit (air handler) is the cabinet inside the home. Choose how it sits, then measure the inside of the closet or the clear space in the attic. Leave a box empty if you do not know it.
Not every air handler fits every closet. Short wall-mount cabinets are about 36 in. tall. Standard cabinets run from 42.5 to about 62 in.

About these options. Matchups, ratings, AHRI reference numbers and cabinet sizes come from our suppliers’ AHRI matchup sheets dated June to November 2026. Manufacturers change models and ratings, so the AHRI certificate number is confirmed on your digital estimate. You can look up any reference number at ahridirectory.org.
About sound. The dBA numbers are estimates from the manufacturers’ lab sound data for the unit while cooling. Bosch and ClimateMaster test in different ways, so compare sizes within one brand, not one brand against the other. What you hear in the room depends on the closet, the door and the ductwork.
About fit. Sizes are the cabinet only, in inches. Ducts, the drain line, wiring and service access need more room, and a technician confirms the fit and the size of the system on the free estimate visit.
New installations come with a 1-year labor warranty and up to 12 years on parts, depending on the manufacturer. A city permit is pulled on every installation.
