We are located in Scottsdale, AZ, and are planning to install a heat/cool pump to extend the pool season (in ground, ~16k gallons). The pool company recommended Pentair 120 R HC or Aquacal SQ 121. We looked at both units and did not see a significant difference in specs (COP, BTU, refrigerant, compressor, noise level, price). Aquacal offers a great warranty in FL but not in AZ which concerns us as they might have concerns regarding the reliability of their units in our climate. They offer an extended warranty at ~$500/3 years which is quite expensive. Pentair would allow us to tie the unit into our existing Sun Touch control system.
Insights regarding reliability and any recommendations would be appreciated.
