Business ProfileforBrisk Air, Inc

I called them a month ago, ac coils were frozen. Tech came and was very professiional and competent. We were very low on freon. He added and advised there may be a leak, paid $738. Wrote om the **** that an isolation test was $691 if we need to locate a leak. 3 weeks later same thing. Pay again for emergency service again $560. On new **** it said same thing isolation test $691. I schedule isolation test for 3 days later. Paid **** when he came and performed isolation test . 2 days no ac last week during 90+ degree weather. He comes back 2 days later and gives us the results for the isolation test and they cannot fix the problem till a "project manager" can evaluate the cost and how to proceed. We are told the project manager will not be available for 7 Days!! He then tells us, to hook back up our ac will be another $540. NEVER on any of my estimates for the isolation test was there any mention of a reconnection fee. I refused to pay. I called the office and complained. I was able to get the project mgr to come next day, so without ac another day. He looked at whole job which was a big job, replacing copper line and rerouting them through attic. He assures me he will take care of us and give us a fair price but we MUST pay him $500 to reconnect our ac till he can do the job. I HAD NO CHOICE!! Paid him 500. Four days later he gave us a price of $7300 to do the job. Meanwhile I had 4 other ac companies give me estimates from $2500 to $3400. All the other companies gave me the price within 1 hour. I had the job completed the next day by Air America for $3195 I feel betrayed and bent over a barrel and taken advantage of. My next step is contacting the Better Business Bureau to file a complaint because no where in any of their emails and bills did they tell me of another expense to reconnect my ac after the test, not to mention the more than double price to complete the other job. Very very poor way to people when there is a problem
