This is the most horrid Air Conditioning repair and sales company I've ever come across.
They sell new units, install them incorrectly, do not stand behind the product, and keep charging you for items covered by warranty, or worse.. parts not needed.
When confronted, they take the parts and disable the appliances.
Rude and sneaky. The worst of the worst.
Save yourself the time, trouble and money, and go somewhere else.. ANYWHERE else!
