Replaced my furnace and a/c unit. Was looking at possibly $6,000-$7,000...Ronier did it under $5,000. He was informative in old unit, what units were good and not so good, what will work in the size of my home, gave me link for financing...excellent information. Installation of my units was about 3 hours. Work was superior and they cleaned up and hauled away old units and any debris. I have already spoken to several people and gave out his phone number to one. Thank you, Ronier for your professionalism and care!
