Ac and heating repair service near Brookfield, IL

Review Very negligent and irresponsible. Let them know engine had old sludgy oil stuck to engine for last 3 years and did not pass emmisions. I wanted their opinion on the possibility of passing emissions.  After cleaning oil control valve and all passengers in cylinder head. They told me to drive the car and bring back for emmisions check. I drove the car about 15 miles and the engine locked up as a result of work performed. They refused to take responsibility after never letting me know this could happen. They did not advise me that their tinkering could render my car undrivable.  They should have informed of the risk and given the choice of deciding.

I brought my car in for a diagnostic and they gave me over a quote for over $3,000 in repairs. I took it down the street for a 2nd opinion and half the things they said were wrong was a lie. Had my car repaired where I got thr and opinion for less than 1k. It's been 6 months and not a single problem. A dealership and repair shop run by conmen. Color me surprised (NOT)
