This is the second time I have had electrical work done by AUX. Patrick and Derrick did both jobs for me and I could not be happier with the outcome. They are both professional and very conscientious. They wanted me to be totally happy with the work. I have additional items I want done and will definitely have them back out. I would high recommend them for any electrical work you need.

Best people for your job. Called and setup an appointment. Instant response. Worked past quieting time to complete the job. Both people had a great attitude in the rain and on the job.5 stars is not enough to rate these people. I plan on using them anytime for all my home services. Thanks Patrick and AUX Home Sevices

Report
I had to reschedule but I did not have an emergency and there had been torrential rains, so I knew that others had immediate problems. I was kept informed. When Caleb showed up he was professional and well prepared to clean the underground drains from my downspouts. It did it all for the quoted special price of $99. He was knowledgeable and everything went well. Compare to the ridiculous price of $500 that Roto-Rooter wanted + another $300 because Roto-Rooter's old truck could not get up the hill and he expected ME to pay for their inadequacies. This is the best plumbing company I have found since moving here two years ago.
