The AURA 33k is Senville's largest single-zone system, holding a -22F heating floor at 2.75 tons - which is genuinely rare, since most brands abandon deep-cold capability at this capacity. Efficiency drops to SEER2 19.5, the expected taper at the top of a range. If you need one large head that still heats through a hard winter, this is a short list and Senville is on it.

Frequently asked questions

Can I install the Senville AURA 33,000 BTU R-454B 208/230V (SENA-33HF-IGG / SENA-33HF-OG) myself, or do I need a pro?
Senville AURA 33,000 BTU R-454B 208/230V (SENA-33HF-IGG / SENA-33HF-OG) 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 33,000 BTU R-454B 208/230V (SENA-33HF-IGG / SENA-33HF-OG) keep heating in a cold winter?
The manufacturer publishes 35,000 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 33,000 BTU R-454B 208/230V (SENA-33HF-IGG / SENA-33HF-OG) need?
Published electrical requirements: 187-253 voltage, 34 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 25 ft, and the included line set comes pre-charged for 25 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 33,000 BTU R-454B 208/230V (SENA-33HF-IGG / SENA-33HF-OG) carry?
The manufacturer publishes these warranty tiers: Standard: 5 yr parts / 10 yr compressor (published warranty terms). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
