"Frostcore made contact with me immediately and we scheduled a same day appt. due to my AC Blower which had stopped working. It is a very hot and humid day and Sami and his business partner explained throughly what repairs were needed to get my AC unit working again. They gave me a fair estimate and final price and I intend to give Frostcore my repeat business. They were both very knowledgeable friendly and pleasant to work with and I welcome them as my future cooling and heating pros. Thank you."
