The LG Extended Piping 24k is built for installs where the outdoor unit sits far from the indoor head - it supports longer refrigerant line runs than a standard single-zone. Ratings are respectable for the class: SEER2 22, EER2 13, HSPF2 9.7, with 24,000 BTU of heat at 47F and 20,000 BTU held at 5F on R-32. It solves a placement problem other 2-ton single-zones cannot.

Strengths

  • Supports extended refrigerant line lengths - flexible outdoor placement for tall or spread-out installs.
  • 24,000 BTU at 47F and 20,000 BTU at 5F - strong cold-climate output.
  • SEER2 22 with current R-32 refrigerant.

Weaknesses

  • A specialty line-length product; if a normal run works, a standard 24k is simpler and often cheaper.

Frequently asked questions

Can I install the LG Extended Piping R-32 24,000 BTU (230V) myself, or do I need a pro?
LG Extended Piping R-32 24,000 BTU (230V) 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 LG Extended Piping R-32 24,000 BTU (230V) keep heating in a cold winter?
The manufacturer publishes 20,000 BTU/h of heating output at 5F. Rated heating operation extends down to -4 F. Certified heating efficiency is 9.7 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 LG Extended Piping R-32 24,000 BTU (230V) need?
Published electrical requirements: 208/230V voltage, 19 A minimum circuit ampacity, and 30 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 164 ft, and the included line set comes pre-charged for 24.6 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 LG Extended Piping R-32 24,000 BTU (230V) carry?
The manufacturer publishes these warranty tiers: Standard: 5 yr parts / 7 yr compressor (standard coverage); Best case: 10 yr parts / 10 yr compressor (qualified registered installation). Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
