They sold me an A/C unit at $5,000 that later I found out was being sold at just over $3,100 with other A/C companies. On a maintenance visit 2 years later the A/C coil of that same unit 'broke' for no apparent reason and they wanted to charge me an extra $1,000 for 'labor' even though it was covered under the warranty. I called another A/C repair company since I figured a 2 year old coil would not break down easily and the technician confirmed my suspicion that the A/C coil was tampered with and broken by external means by someone who knew how to break it without damaging other parts of the unit. Cornerstone Air Conditioning & Heating Inc. is extremely dishonest and criminal in their practice, they should be avoided at all cost. I will be following up with a complaint with the BBB and I want to advice to all of you to stay away from these criminals but don't take my word for it, you can call them up and roll the dice yourself, it will only cost you a good amount of your hard earned money to prove me wrong. That is if you think it is worth it to ignore this warning.
