This value 12k runs on a 115V circuit and comes in at 21.4 SEER2 with a low 10.0 EER2 and 8.7 HSPF2 on R-454B. It is not ENERGY STAR certified and not cold-climate designated, and its heating reflects that - 12,000 BTU at 47F falling to 9,000 BTU at 17F and 7,000 BTU at 5F. The appeal is straightforward: one-ton capacity on easy 115V wiring at a budget price.

Frequently asked questions

Can I install the Midea Essence 12,000 BTU R-454B 115V (D5FEHAH12XCJ / D5CERAH12AAJ) myself, or do I need a pro?
Midea Essence 12,000 BTU R-454B 115V (D5FEHAH12XCJ / D5CERAH12AAJ) 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 Midea Essence 12,000 BTU R-454B 115V (D5FEHAH12XCJ / D5CERAH12AAJ) keep heating in a cold winter?
The AHRI/ENERGY STAR certification lists 7,000 BTU/h of heating capacity at 5F. Rated heating operation extends down to 5 F. Certified heating efficiency is 8.7 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 Midea Essence 12,000 BTU R-454B 115V (D5FEHAH12XCJ / D5CERAH12AAJ) need?
Published electrical requirements: 115 V voltage. 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 164 ft. Measure the planned routing before ordering.
What warranty does the Midea Essence 12,000 BTU R-454B 115V (D5FEHAH12XCJ / D5CERAH12AAJ) carry?
The manufacturer publishes these warranty tiers: Registered: 10 yr parts / no separate compressor term (timely registration). Score uses Registered.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
