I love that this program has all my customers in one place! It's very user friendly as well so no matter what your skill level you can still get things done with ease using their site/applications!! The customer service from them could always improve however they are great at responding quickly when there isn't anything wrong or needed changed within our account (which happens quite often). You will find yourself needing more than 1 computer screen just trying to navigate through everything available because some areas have too much information - which gets confusing sometimes if not used correctly-but overall its been pretty good thus far. We've had several new clients come into business since we started utilizing Simpliehvac over 2 years ago now & haven't regretted putting any money towards purchasing an application like theirs yet either :) I like that the software is easy to use and very user friendly. The software is easy to use and very user friendly. I also like that it is easy to add and delete equipment types. I dislike that it is not possible to export the information to other programs like Excel. I recommend Simple HVAC to all sheet metal contractors. I use Simple HVAC to help estimate my projects.
