Yes, it might seem expensive, but it is worth the money. You'll never want to experience troubles again, don't you? So if you need quality, you need to provide enough resources. I know people who paid a lot more, so you should be happy with the bill you can receive. If you are unsure about that, get yourself a new specialist and see what he'll tell you. Probably, you'll get a more significant amount of money to pay. My air conditioning installation cost me a lot, but it lasts until today, and I'm delighted with it; by that, I mean that sometimes we have to forget about the money and look for the quality.
