Malibu Heating and Air conditioning provided a detailed fair quote, the most detailed one I received. They installed top grade Mitsubhishi HVAC heat pump. The installers were professional and did an outstanding job going above and beyond expectations. We are extremely happy with the installation, quality, and professionalism of the entire purchase life cycle. I am going to reccommend Malibu to everyone in the building who needs their aging HVAC replaced.
