The Senville AURA Multizone 4-Zone 28k (SENA-28HF-MOA) is a value cold-climate four-zone engineered so heating strengthens rather than fades as it gets colder. It posts a certified nominal SEER2 of 23, EER2 12.5, and HSPF2 10.5, and its heating actually rises from 27000 BTU at 47F to 30000 at 17F before returning to 27000 at 5F - output above its 47F rating deep into the cold.

It runs on current low-GWP R-454B refrigerant, is ENERGY STAR certified, and is AHRI cold-climate designated. Senville is a popular value ductless brand whose AURA line is well known online, delivering high-efficiency inverter multi-zone below the premium names.

Professional installation is required and units are dealer-quoted.

Sizing note: do not just add up the rooms. Multi-zone condensers have a maximum total connected capacity, and connecting more head capacity than the unit is rated for is a common installer mistake that hurts efficiency and comfort. Match total head capacity to the condenser's rating.

Frequently asked questions

Can I install the Senville AURA Multizone 4-Zone 28,000 BTU R-454B 208/230V (SENA-28HF-MOA) myself, or do I need a pro?
Senville AURA Multizone 4-Zone 28,000 BTU R-454B 208/230V (SENA-28HF-MOA) is built for professional installation: the line set must be flared, evacuated, and charged, which requires EPA-certified refrigerant handling. Installing it outside the manufacturer's requirements can void the warranty, so budget for a qualified HVAC installer.
Will the Senville AURA Multizone 4-Zone 28,000 BTU R-454B 208/230V (SENA-28HF-MOA) keep heating in a cold winter?
The manufacturer publishes 27,000 BTU/h of heating output at 5F. Rated heating operation extends down to -22 F. Certified heating efficiency is 10.5 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
What electrical circuit does the Senville AURA Multizone 4-Zone 28,000 BTU R-454B 208/230V (SENA-28HF-MOA) need?
Published electrical requirements: 230 V voltage, 30 A minimum circuit ampacity, and 35 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
How far can the outdoor unit be from the indoor head?
The published maximum line-set length is 262.4 ft, and the included line set comes pre-charged for 100 ft. Longer runs than the included set allows typically mean added refrigerant and a pro visit, so measure the planned routing before ordering.
What warranty does the Senville AURA Multizone 4-Zone 28,000 BTU R-454B 208/230V (SENA-28HF-MOA) carry?
The manufacturer publishes these warranty tiers: Standard: 5 yr parts / 10 yr compressor (registration/professional-installation terms). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
