Dear Sirs,

I want to thank you for introducing us to your filter service. Our company has no program in place to service the filters for the unit on the roof. I have found the cost to be very reasonable and the value of having a heating and cooling system that works when it is needed is essential. The cleanliness of the store alone, more than pays for the service.

I would recommend FSI/Northwest for the service that they provide.

Sincerely,
Ken Fox

Manager/ Salem North
