Polar Express Plumbing, Heating and Air Conditioning can install a mini-split AC in Corona, CA. Mini-split systems don’t need ductwork to function. We install a compressor outside and small handlers inside your home. The setup includes a conduit to link the compressor and indoor handlers. Ductless AC systems are efficient and give you the ability to fine-tune the cooling within each room. They also work well in small homes and apartments. If you’re adding a room to your home, then you might find that a mini split is a convenient choice for giving it air conditioning.
