We have used Metro Energy for the last 2 years when we bought our home. Anytime we have called they have been there within the hour. Their service men are professional and very knowledgeable, always ready to explain what's going on and always have some money saving tips as well. When they came out last week he suggested that we put up a small fence around the compressor to keep our dogs away when nature calls because this ruins your copper. Who knew! Fence is up and we will always use Metro.
