I've called them on two occasions. Our AC quit. I called Gillece and set up an appointment. Took the day off work to wait. They didn't show up. In my free time I decided to check them out on the BBB website. I was glad I did. I called them back and cancelled the service call. I chose a vendor who had a much better rating. I had called them once before about a clogged drain line. They told me I would have to have them break up our driveway and replace the line. I looked down the vent hole and could see a stick. I bought a tool for a few dollars and was able to pull up the stick. I replaced the broken vent cover with one from Home Depot. The whole job set me back about $20 instead of the thousands it would have cost me had I allowed them to proceed. I'd stay as far away from these people as possible.
