Unless there's an active leak, there's no reason.

As for any oil tank, if they're leaking oil into the ground then yes you have an environmental issue to deal with. 

Did someone install too small a system, did the Freon leak out, are the air filters dirty.

Sorry. iOS means any Apple device. iPhone or iPad. 

If you have an iphone and a printer that can receive directly from the iphone, you can snap pics of small receipts send them to the printer, then punch holes in them and file them that way.Here is a video that is a little bit boring how about filing.

I'm working on putting together an APP that you can download on android or iphone to make it easier to use.

And also look in markets where it seems even some of the top performing listings still have ikea furnishings and iphone photos.For example, in the Poconos market, many listings are still marketed poorly like this, and most homes are 3-4 bedrooms.
