About LG
LG Electronics is a South Korean company best known for TVs and home appliances, but it's also a serious player in HVAC. Its ductless mini-splits and multi-zone systems are common in homes, and its Multi V systems are used in commercial buildings.
In Santa Clarita we see LG mini-splits in additions, converted garages, ADUs and homes that were never ducted. Some homeowners install one LG head for a hot room upstairs and leave the rest of the house on central air. That works well.
What LG offers
LG's home HVAC lineup centers on ductless inverter heat pumps:
- Single-zone mini-splits: one outdoor unit, one indoor head, for a single room.
- Multi-zone systems: one outdoor unit running several indoor units, each room set separately.
- Art Cool: design-focused wall units for people who care how the head looks on the wall.
- Ceiling cassettes and ducted units for a cleaner look or for serving several rooms through short duct runs.
- Multi V: VRF systems for larger and commercial buildings.
Many LG units connect to the LG ThinQ app for control from your phone.
What's new with LG
The big change is refrigerant. Starting in 2025, new central AC and heat pump systems sold in the US moved off R-410A to lower-impact refrigerants, mostly R-454B or R-32. Ductless systems are part of the same transition. Ask us which refrigerant a specific LG model uses. Your existing R-410A system is still legal to run and repair. The catch is that new and old refrigerants don't mix, so a new outdoor unit usually means a matching new indoor coil too.
LG has been expanding cold climate heat pump options and ducted inverter systems aimed at replacing a traditional furnace and AC. The ThinQ app gives you scheduling and remote control, and some models can show error information there too. For the valley, LG multi-zone is a practical way to cool bedrooms upstairs without reworking ductwork.
How LG compares
LG is usually priced below Mitsubishi and Daikin, which makes it an attractive pick for single rooms and budget-minded multi-zone jobs. Performance on mainstream models is good.
The trade-off is mostly in parts and service. LG's HVAC parts are model-specific and sometimes need to be ordered rather than pulled from a local supply house shelf. Diagnosis depends on LG's error codes. For a whole-home system where you want the longest track record, Mitsubishi or Daikin may be worth the extra cost. For a single room or garage, LG is often a sensible choice.
Common problems we fix on LG systems
LG HVAC problems we see most:
- Blinking light or error code: sensor, fan motor, or communication fault.
- Not cooling: refrigerant leak or a failed sensor.
- Water dripping from the head: clogged drain line.
- Bad smell from the unit: mold and dirt on the coil and blower wheel.
- Noisy indoor or outdoor unit: fan motor, debris, or loose mounting.
- Cold air in heat mode: defrost or refrigerant issue.
Install or repair an LG system with WY&G
For LG mini-splits we read the error code, check the matching part with a meter, and only order what we've confirmed is bad. If a part has to be ordered, we tell you up front how long it's likely to take.
