Had the company install a new heating and air unit on our house. We hired them as a Home Depot certified company. 13 months after the installation the air conditioner is not functioning. Called to schedule an appointment and was told the service warranty is up 12 months) and they have absolutely NO appointments available. Of course they promise you the world when trying to get you to buy a new unit. HORRIBLE company. Keep looking and hire someone else!
