Beware of the 99.00 fee that they try to charge you once your appt. is over....whether you use them or not......Made my appt. for a possible whole home surge protector...after a longer then needed appt. and beating around the bush answer...plus an astronomical estimate in the thousands...we decided no and were told there would be a fee of 99.00...I was NEVER told of this fee when I made my appt. or I would NOT have used them, thankfully after this was stated, the fee was waived. Just be careful and ask before they come to your home. Andrea R.
