"Amer Talla is the best! He knows the industry, he is an expert HVAC person all-around. Actually, he is a general contractor. He diagnosed the problem, provided a detailed solution, and was the consummate professional. He is not just the expert you should call because he is knowledgeable and professional, BUT he is thorough. You can tell he loves what he does and he cares about his customers. He’s the one I will call for future maintenance and anything else HVAC-related. I highly recommend him!"

"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."
