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 on R-32, with 24,000 BTU of heat at 47F and 15,800 BTU at 17F; LG's submittal lists at most 16,580 BTU at 5F. 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 15,800 BTU at 17F - solid 2-ton 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?
Rated heating operation extends down to -4 F. Certified heating efficiency is 9.7 HSPF2. Match that published heating floor against your climate's design temperature - below the low-ambient rating, output can fall off or the system can pause to protect itself.
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. The outdoor unit's factory charge covers up to 24.6 ft of line; longer runs need added refrigerant. 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: Base: 5 yr parts / 7 yr compressor (standard coverage); Registered: 10 yr parts / 10 yr compressor (registration within 60 days of startup, by an installer with current LG training and an HVAC license). Score uses Registered.. Registration requirements and proof of qualified installation commonly affect coverage, so read the warranty terms before install day.
