2 Ton Mitsubishi 19.5 SEER2 R454B Side Discharge Inverter Heat Pump System SUZAA24NL, SVZAP24NL
At 19.5 SEER2, the Mitsubishi SUZ-AA24NL outdoor heat pump paired with the SVZ-AP24NL ducted air handler is the most efficient size in this R-454B inverter series. The AHRI-matched system (AHRI 215734905) is rated at 22,800 BTU/h cooling with an 11.8 EER2 and 9.4 HSPF2, and it produces 25,000 BTU/h of rated heat at 47°F. Homeowners replacing a tired 2 ton split system, landlords upgrading rental units, and contractors who want Mitsubishi inverter efficiency through standard ductwork will find this the sweet spot of the lineup.
Is a 2 Ton Heat Pump System the Right Size?
A 2 ton system commonly serves mid-size homes, larger condos, and individual floors of a multi-story house, often in the range of roughly 900 to 1,200 square feet in typical construction. Since the SUZ-AA24NL modulates between 9,000 and 22,800 BTU/h in cooling, it can match a wide spread of daily loads, running gently through spring evenings and ramping up during peak summer afternoons.
Your real load depends on attic and wall insulation, glass area and orientation, air leakage, duct condition, how many people live in the space, and how cool you like it. Coastal and humid climates also put extra weight on latent (moisture) removal, and this system is rated to remove 5.6 pints of moisture per hour at standard cooling conditions. A load calculation confirms whether 2 tons is the right fit before you commit.
Ideal for: Two- and three-bedroom homes, larger condos and townhomes, upstairs or downstairs zones of two-story homes, rental properties, and small offices that want the highest SEER2 rating in this Mitsubishi series.
Need more capacity? Step up to the 2.5 Ton Mitsubishi SUZAA30NL & SVZAP30NL Heat Pump System for homes and zones that need more heating and cooling output and a larger air handler.
Recommended applications are general guidelines only. Actual system requirements depend on a load calculation, insulation, windows, climate, ductwork, occupancy, and desired indoor temperature. Request free sizing assistance, contact Budget Heating, or call 813-885-7999.

Mitsubishi pairs the SUZ-AA24NL with the same compact 17" wide cabinet used on the 1.5 ton air handler, but the SVZ-AP24NL moves up to 700 CFM on its top speed, and the outdoor unit steps up to a 5/8" gas line with 100 ft of allowable height difference. Compare it against other 2 ton heat pump systems with backup heat strip options, and finish the install with a 25 ft 1/4" & 5/8" insulated copper and 14/4 wire combo. If you are reusing existing lines, an Easy One-Step Rf11 flush kit helps clean out old oil and debris before you connect the new R-454B equipment.

Frequently Asked Questions
How much space can the 2 ton SUZ-AA24NL system handle?
The SUZ-AA24NL is rated at 22,800 BTU/h cooling and 25,000 BTU/h heating at 47°F, which typically suits mid-size homes, larger condos, or one floor of a two-story home. Final sizing should come from a load calculation that accounts for insulation, windows, and your local climate.
What do I gain by stepping up from the 1.5 ton SUZ-AA18NL to the SUZ-AA24NL?
The 2 ton system adds roughly 4,800 BTU/h of rated cooling and 5,000 BTU/h of rated heating, moves up to 700 CFM instead of 675 CFM, and raises efficiency from 16.2 to 19.5 SEER2. It also uses a 5/8" gas line and allows 100 ft of height difference instead of 50 ft.
Why does the 2 ton model have the highest SEER2 rating in this Mitsubishi series?
In Mitsubishi's matched-system data, the SUZ-AA24NL with SVZ-AP24NL reaches 19.5 SEER2, compared with 16.2 for the 1.5 ton, 17.8 for the 2.5 ton, and 15.8 for the 3 ton. The 2 ton outdoor unit is built on the same larger cabinet and compressor platform as the 2.5 and 3 ton models, so it has extra capacity to spare at its rated load.
Does the SVZ-AP24NL air handler include an R-454B refrigerant leak sensor?
Yes. The SVZ-AP air handler has a factory-installed refrigerant leak detection system for R-454B. Mitsubishi requires the unit to stay powered except during service, lists a 15-year sensor life, and says it should not be installed where a drop ceiling is used as a return air plenum.
Can the SVZ-AP24NL be installed in a closet, attic, or crawl space?
The air handler is multi-position and can be set up for upflow, downflow, or horizontal left or right airflow, which covers closet, attic, and crawl space installations. Mitsubishi offers a DFK-S downflow kit and recommends the CMA-1 for proper condensate management in downflow setups.
Can I control this 2 ton Mitsubishi system with a wall thermostat?
Yes. The system works with Mitsubishi wired and wireless controllers, including the MHK2 RedLINK wireless thermostat offered as an option. Mitsubishi also offers the PAC-US445CN-1 thermostat interface for compatible third-party thermostats.
