Description
SUZ-AA15NL-SLZ-AF15NL is a Mitsubishi Electric single-zone heat pump system built around a four-way ceiling-recessed cassette. The SLZ-AF cassette delivers comfort from above while keeping the space clean and uncluttered. The SUZ-AA outdoor unit is matched one-to-one for a straightforward performance story. This NL generation uses R-454B refrigerant, aligning with the A2L low-GWP equipment direction. Four-way air delivery is designed to reduce hot and cold zones by spreading airflow across the space. Customers pick this style when they want a premium look without giving up efficiency. It’s a strong option for main living spaces, suites, and offices where appearance matters.
Rated cooling capacity is 15,000 BTU/h, with a listed maximum of 15,000 BTU/h. Minimum cooling capacity is listed at 3,600 BTU/h to support steadier control when loads drop. Moisture removal is listed at 3.8 pints per hour for stronger humidity comfort support. Rated cooling power input is 1,240 W, providing a clear number for operating-cost comparisons. Sensible heat factor is listed at 0.72, showing more focus on moisture management at this size. Variable-capacity performance helps reduce temperature swing compared to legacy single-stage systems. That smoother comfort is what customers notice day to day.
Rated heating capacity at 47°F is 18,000 BTU/h, with a listed maximum of 19,600 BTU/h. Minimum heating capacity at 47°F is listed at 4,600 BTU/h for better shoulder-season comfort control. Heating capacity at 17°F is listed at 11,300 BTU/h for a real cold-weather reference. Heating at 5°F lists a maximum capacity of 9,600 BTU/h to support continued output in lower temperatures. COP at 47°F is listed at 3.3, supporting an efficiency-forward heating story. HSPF2 is listed at 10.1, helping buyers compare seasonal heating value. If the customer wants electric heat that stays comfortable without constant cycling, this pairing fits.
Airflow rate at cooling, dry is listed at 245, 315, or 405 CFM depending on fan speed. Four discharge vanes support flexible airflow direction to match different room layouts. Indoor sound pressure levels are listed at 27, 34, or 39 dB(A) based on fan speed selection. Outdoor sound pressure is listed at 49 dB(A) in cooling and 51 dB(A) in heating. SEER2 is listed at 20.6 and EER2 is listed at 12.0 for clear efficiency comparison. This system is built to feel balanced, not drafty, while keeping noise controlled. That’s the premium ceiling cassette experience buyers are looking for.
Electrical is listed at 208/230V single-phase 60 Hz, which is standard for many residential applications. Recommended fuse or breaker size is listed at 20 A for planning and scope. The ceiling cassette format is a strong match for rooms where wall units are not wanted. It’s also a clean solution for remodels where you want the comfort upgrade to blend in visually. The combination of verified output and strong published efficiency makes the value easy to communicate online. When the spec story reads clean, buyers feel safer moving forward. If you want a 15k ceiling cassette pairing with strong comfort coverage, this is a smart pick.
