Too much spacing in wrap around image.

Good evening! A reoccurring issue i've been having with my pages is the amount of white space around images that wrap around text. Is there some sort of code I can input to tighten up the space around the images? You can see what I'm talking about on each image I have on this page: http://www.hvac-residential.com/mini-splits/ I appreciate any feedback. Thanks in advance.
