42,000 BTU, 15.3 SEER—Efficiently Reliable

With an output of 42,000 BTU and a 15.3 SEER efficiency, the Mitsubishi PVA-A42AA7 / PUZ-HA42NKA is generally able to heat and cool up to a medium-sized house, depending on variables such as your insulation. The unit comes standard encased internally with fiberglass-free insulation, decreasing airflow leakage down to less than 1% in standard conditions. This promotes temperature transfer to your home and decreases runtime of the unit since more of the conditioned air is sent into your home. Moreover, the unit can keep your room heated and comfortable at an outside temperature of as low as -13°F. This Hyper Heat pump functionality reliably keeps your home comfortable even through the coldest months of the year in most climates, and operates at a higher efficiency and at a lower temperature than most other central split systems.


On all of its mini splits, Mitsubishi offers their standard 5 year parts and 7 year compressor warranty from the time the unit is purchased. If the unit is installed following state and local codes and the unit is registered through Mitsubishi, the unit’s warranty is extended to a 10 year parts and compressor warranty, giving you peace of mind that if a rare problem does occur on your unit, you are covered.

Enhanced Comfort

With a variable speed compressor and a multi-speed ECM motor on the air handler, the Mitsubishi PVA-A42AA7 / PUZ-HA42NKA is designed to keep full control over your home’s comfort by changing the unit’s output based on the thermostat requirements. From enhanced comfort in your home to light-commercial climate control, this unit can meet your goals in the space that you need it.

Intelligent Control Options

Mitsubishi manufactures special brand-specific thermostats and controllers for their split systems. One such option, the Kumo Cloud found here, allows you to connect your unit to Wi-Fi and provides convenient control directly to your phone from anywhere that you have Internet access.

Versatile in Application Potential

From standard home comfort to light-commercial climate control, the Mitsubishi PVA-A42AA7 / PUZ-HA42NKA is designed for several different installation applications. The unit can be installed in the upflow, downflow, and horizontal positions to allow for wider application potential. For solutions that require constant heat relief in mild climates, the PVA-A42AA7 / PUZ-HA42NKA is also equipped with a 24-hour continuous cooling mode, allowing you to leave it unattended with the peace of mind that it will still function where you need it most.

Questions and Answers

Customer Questions
What filter options can use for this system?
The unit has a built in internal filter rack that can hold a 20" x 24" x 1" filter.   If you have any further questions please feel free to give us a call! Thanks
What size for a new 2000 s.f. home?
Thank you for your question. The size of system your home will require is based off of several factors including square footage, the climate zone, the number of windows and quality of insulation. For instance cooling a 2,000 square foot home in south Florida with poor insulation and many windows will require a larger system than cooling the same home in Indiana. Please reference our Sizing Guide. This will help you to determine the size of system your unique application requires. For any assistance in this, please give us a call.
