I refused because was not prepared for the bill of 1140/- instead of $ 114/-. The most important thing to inform is after their visit, my electricity bill is doubled, For the last three years, my bills were consistent, but now I don't know what that guy has done to my system, my monthly electricity bills are too high. I wish someone can help me with that.
It sounds like they may have damaged your ducts. If the electricity bill went up, it's probably because the furnace fan (for heating and cooling) and the condenser outside (for cooling) have to run harder and longer. The easiest thing to do is to look for damage to ducts where you can see them. If you see HVAC tape that's missing in the basement, apply that to any air gaps. If that doesn't help the energy bill then you're going to need to get a camera and inspect the ducts inside the walls to look for a broken one. You may be able to figure this out by feeling which room isn't heating/cooling like it was prior to them coming out. They may have also done something to the HVAC unit itself (though this is unlikely). You can get a professional HVAC company to take a look at it.
