I have already recommended Air & Heat Hospital multiple times. They are prompt, they have no hidden costs, and all the times I used them they were in and out, very clean, and backed up what they put in. I had two old A/C units and I called them to replace them. They did such a good job that when my third unit went out I called them again. I trusted them and didn't need to go anywhere else, their services and prices are the best, and I did a lot of research! Their customer service is top-notch, if I ever had any issues they came out the next day to resolve it.
