A: Yes! The I-PAC+ 12 offers heat/cool/auto operation modes. In cooling mode, it can reduce water temperature from 12°C to 30°C, with a cooling capacity of 6.7 kW at 35°C ambient. This prevents your pool from becoming uncomfortably warm during hot summer weather. Auto mode automatically switches between heating and cooling to maintain your set temperature.

Q: What maintenance does it require?
A: Minimal routine maintenance required: (1) Clean air inlet fins periodically with soft brush, (2) Check water chemistry regularly and maintain within specifications, (3) Inspect electrical connections annually, (4) Professional service recommended every 2-3 years. Proper winterization is essential if not used during cold months. Water chemistry maintenance is critical for warranty validity.

Q: Why choose inverter technology over traditional heat pump?
A: Inverter technology provides: 50% lower running costs through variable-speed operation, 9-11 dB(A) quieter operation, no power surges (eliminates massive startup currents), longer component life (no constant on/off cycling), better temperature stability (no temperature swings), and higher average efficiency (COP 10.6 vs 4-5 for traditional units). The extra initial cost typically pays back within 2-3 years through energy savings.

Q: Is the R32 refrigerant safe and environmentally friendly?
A: Yes. R32 has a Global Warming Potential (GWP) of 675 compared to 2,088 for older R410A refrigerant—a 68% reduction. It has zero ozone depleting potential and is F-Gas regulation compliant. R32 is classified as A2L (low toxicity, lower flammability) and performs excellently in cold weather. The environmental impact is significantly lower than older refrigerants.
