3 Ton Mitsubishi 15.8 SEER2 R454B Side Discharge Inverter Heat Pump System SUZAA36NL, SVZAP36NL
The Mitsubishi SUZ-AA36NL outdoor heat pump and SVZ-AP36NL air handler are the largest pairing in this ducted R-454B inverter series, built to move up to 910 CFM through full-size duct systems. Rated in Mitsubishi's matched-system data (AHRI 215748459) at 33,000 BTU/h cooling, 34,200 BTU/h heating at 47°F, 15.8 SEER2, 9.3 EER2, and 8.2 HSPF2, this system serves larger homes, open floor plans, and light commercial spaces that need heavy-duty dehumidification and steady inverter comfort from a single ducted air handler.
Is a 3 Ton Heat Pump System the Right Size?
Three ton systems are commonly chosen for homes and zones of roughly 1,400 to 1,800 square feet in typical construction, but the number that matters is the calculated load. Because Mitsubishi rates this pairing at 33,000 BTU/h of cooling, it is best matched to spaces with a cooling load slightly under a nominal 36,000 BTU/h. Its strong 8.2 pints per hour of rated moisture removal makes it especially effective in humid climates where latent load drives comfort.
Sizing should account for insulation, window area and shading, ceiling height, duct static pressure, occupancy, and appliance heat, plus your winter design temperature. The SUZ-AA36NL heats down to -4°F and is rated at 20,800 BTU/h at 17°F, and an optional heat strip covers extra heating demand. If your load calculation shows more than this system can supply, a larger system is the better answer than running this one at its limit.
Ideal for: Larger three- and four-bedroom homes, open-concept living spaces, humid coastal properties, small offices and retail stores, medical and professional suites, and light commercial spaces with full-size ductwork.

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.

The SVZ-AP36NL uses the same 21" cabinet as the 2.5 ton air handler but runs at higher fan settings of 767 and 910 CFM, giving the 3 ton system more air volume for bigger duct systems and more supply registers. It sits at the top of our 3 ton heat pump systems as the Mitsubishi inverter option. The outdoor unit is precharged for 25 ft of line. Longer runs need extra charge, which you can add from an R-454B refrigerant jug. For short, tidy installs, the 15 ft 1/4" & 5/8" insulated copper and 14/4 wire combo keeps the line set and wiring together.

Frequently Asked Questions
What size home is the 3 ton SUZ-AA36NL system a good match for?
With 33,000 BTU/h of rated cooling and 34,200 BTU/h of rated heating, the SUZ-AA36NL system typically fits larger homes, open floor plans, and light commercial spaces. A load calculation is the best way to confirm that your cooling load fits within its rated capacity.
What is the difference between the 3 ton and 2.5 ton SVZ systems?
Both use the same 21" air handler cabinet, but the SVZ-AP36NL runs at higher fan settings (767 to 910 CFM compared with 613 to 875 CFM). The 3 ton system adds 6,000 BTU/h of rated cooling and 4,200 BTU/h of rated heating, and it removes 8.2 pints of moisture per hour compared with 5.5.
Is the SUZ-AA36NL the largest outdoor unit in the SUZ-AA series?
Yes. Mitsubishi's SUZ-AA series covers the 18, 24, 30, and 36 models, and the SUZ-AA36NL is the top of that range. All four share the same 33-1/16" W x 13" D x 34-5/8" H side discharge footprint, which makes it easy to fit in tight side yards.
How loud is the SVZ-AP36NL air handler?
Mitsubishi lists sound pressure levels of 47 to 49 dB(A) for the SVZ-AP36NL across its fan settings. Higher airflow is the reason it runs a bit louder than the smaller SVZ models.
What warranty comes with this 3 ton Mitsubishi heat pump system?
This system is listed with a 10-year manufacturer warranty. Warranty terms and any registration requirements are set by Mitsubishi, so contact Budget Heating with any coverage questions before installation.
Will the SUZ-AA36NL handle humidity in hot, muggy climates?
Yes. In Mitsubishi's rating data, this system removes 8.2 pints of moisture per hour at standard cooling conditions, the highest in the series. Inverter operation also lets it run longer, steadier cycles, which helps pull humidity out of the air instead of short-cycling.
