We want our electric meter checked for any faults because our last a/c was over the top, for 2 people who have gas hot water and gas cooking. If the meter was faulty, no charge, and I assume it would be remedied. HOWEVER. If there was nothing wrong, we would be charge nearly $500. AND I WANT TO KNOW WHY such a huge charge, to prove an electric meter is OK. Can AGL please explain.
