My airconditioner is 8 years old. the technician said he needed to add 7 lbs of refrigerant and i believed him. So, the checkup went from $87 to over $1000. He then asked me if i wanted him to check for a leak. I said yes. He never told me it would cost another $300 until I got the bill. I thought it would be in the first bill. He was polite, but I was livid. I will not use Huft again.
