They make you sign a one-year agreement for a short-term problem. Then they come to your house for servicing without an appointment and when you are not home and claim they are treating your house.
They supposedly treated my house-- there was 2-3 feet of snow all around. What could they be treating with snow covering my house? And I wasn't home to see what they had done. I had repeatedly requested for them to make an appt with me and not just show up, but they never honored my requests.
Never use this service. It is a huge rip-off.
