Whatever you do do not use these people to help you with your AC or heating problems. They are negligent and irresponsible. They replaced the ducting in my home with ducting that was too large and there is no airflow in 4 of the 6 vents in the house. They refused to take responsibility for their errors after several other companies and professionals noted their mistakes. There is a little boy in the home who has seizures when it gets too hot in the house and the family who is living there is struggling with their monthly bills especially their energy bills, and still they take no responsibility and have no compassion. Not saying they're totally evil, but if you have a choice do not use them for any work that you may need. Unless you want to find yourself in a two year battle like I have. One star is generous..Stay away!!!
