They come when I need them and when they’re here, they are very knowledgeable in what they are doing and very thorough. After the job is done, their quality manager calls us to make sure that everything is fixed. Also, I appreciated that when we had issues with our electricity, they gave us a warranty card for 4 days, so that if the problem reoccurs, they will come and fix it again at no charge. I have recommended them to most of our friends in our community.
