I've used Air & Heat Hospital for quite some time now. They recently installed a new air conditioning unit in one of my rental properties. Before this, they replaced two air conditioners in other properties for me and I use them for yearly maintenance. Air & Heat Hospital is easy to work with. They conveniently schedule appointments and I am very satisfied. The techs fix what is broken and they don't have to come back. I also think that their price is very fair. I recommend Air & Heat Hospital!
