Prompt, courteous service at a fair price.
My mother's air conditioning unit was due for replacement. Having had a good experience with Hammock's before at my own house, I called them for an estimate. The sales consultant showed up on time that same day, only three hours later. Within thirty minutes, we had a fair estimate in hand, some $800 cheaper than another company that bid the job earlier. The next day, the crew was on time, did the work in a professional manner, cleaned up, and didn't try to increase the bill by even one penny. I'm not sure how you can do any better: These guys are on time, courteous, and professional, and they do all of this for a great price.
