I'm a bit late to this thread but figured I wold let you know I have the 29,000 btu unit in my house. A small cape. Cools the whole house but I do keep a fan to blow it into the bedroom as it does not push the cold air into every room upstairs. Not a big deal but you might find you need a fan in some spots to deliver the heat/cooling. We use the same vendor and they usually have a service special that you can pay for each spring. Ours is $179.00 I think. They will come out and clean everything and tune it up. We have had ours for over 6 years now and you will be surprised how much dust builds on the drum fan even with cleaning the two front filters. Having two cats does not help with that....
I always tip the guys when they come as they have to climb under my deck to get to the condensor, plus I figure if I take care of them.....They will take care of me should the need arise. But they do a great job any way. And everyone that has shown up to my house for the install and cleaning were very nice and always polite. (Nice to see that in a company now days.) Great crew. Great company. We are thinking about getting another small system to do the upstairs bedrooms on their own.
If you get it....you will love it.
