I currently have two window units, a 12,000 BTU first floor level and a 10,000 BTU upstairs, and they cool the house of adequately. But, I'm getting older and installing/removing window A/C units is getting to be a real hassel; they are heavy and awkward to carry. So, I'm thinking of ductless A/C systems. Unfortunately, I know little about them and do not know of anyone who has used them.
Are these good alternatives?
Are they expensive?
Are they efficient?
Are they easy to install?
Are multiple units required to cool an entire two level house of 1800 Sq. Ft. each level? (Afraid I know the answer to this one).
Can you recommend a good manufacturer?
Is this a handyman installation or better to have a factory rep install?
Sorry for all the questions, but I'm trying to get a handle on this. If you can point me to good reference material, I'll follow up there.
Thanks for your help.
