We paid for a house call because they had good reviews and they tried to sell us a product we didn’t need. They used our young kids to try to make the sale saying because we had young children we shouldn’t take the chance. They also kept calling us all day offering to give us a bigger discount each time. Then the sales man called us and said he had the product at his house and could sell it to us for half the price. We just asked for a price to replace our central AC unit and never heard back from them. Our AC unit has still been working fine without the product they wanted to charge us hundreds of dollars for. They never got back to us with a price on replacing our AC unit. Don’t trust what they say is wrong they are just trying to make sales.
