Stay away!!! They over price everything and the tech Robert is a complete joke. This guy is a liar and any company that would hire him is questionable. I ended up needing a complete brand new unit and before I agreed to purchase it they were at my house calling me asking why I wasn't answering the front door. Not only did I not ok the purchase but never agreed to a time to instal. Goodluck getting a receipt for your records. When the technician robert told me flat out that he is surprised they haven't fired him yet, makes you wonder what's going on over there. Stay away.
