I will use Castel JUST because of Ricardo! I have a bad taste in my mouth over heating/air companies. Lenox treated me horrible and Relaible took advantage of my mother after my father had JUST passed away and basically stole $7,000 from her. Ricardo came out and was A- such a gentleman and B- very knowledgeable of the system and what needed to be done. He went above and beyond to ensure everything was done properly!! I was completely impressed in the way he did his job. He respresented Castel AMAZINGLY!! They should be extremely proud to have an employee such as him on his team!!
