Howard - The unit was $5100 and I get a $300 tax credit for this. Also it doesn't change my tax basis as my Florida room is not on the same level as the house. You have step down a couple of inches when entering it. The unit is terrific and very quiet. I will be glad to discuss this at our next golf gettogether if you have any further questions. I can wholeheartedly recommend Mid-Fla for the work.
