Cornerstone Air, Heating & Plumbing

DO NOT USE Cornerstone air. They are a dishonest company/ manager and owner included, with incompetent, unskilled service techs. I bought a brand new a/c unit from them- very expensive. I also purchased a service contract with them to maintenance the unit. They sold be a unit that has had multiple problems. They have been unsuccessful with repairing the unit. They have avoided all of my calls refusing to come out to do warranty work and let me use my service contract. They have admitted that the unit is faulty and want to wipe their hands clean of it. They left me with a big mess of water stained and mold covered ceilings and a mess of an mold and water filled attic. In addition, they have dishonest repairman. On one appointment that I had with them, the tech asked me if I had any other problems in the house and I did have a problem with my dryer vent. They Cornerstone tech sold me that they repair a/c, plumbing, and electrical, and he would gladly repair my dryer vent. He did the job and he said his credit card swiper wasn't working so I had to pay him my cash or check. I wrote him a check and he said that he would bring it to Cornerstone and write up a invoice and mail it to me. The work he did was faulty so I called Cornerstone to ask them to come to look at it. The manager/owner of Cornerstone air said that he knew nothing of this repair and refused to take responsibility for his employee. He told me that the company was not responsible for their employees doing this type of work. I have been trying to get them to come out for nearly a year now to come out and paint the ceiling that was supposed to be covered under the manufacturers warranty due to a faulty unit. I have also been calling them to have a service man come out to service my unit because I have water and mold all over my ceiling right below the a/c unit. They have avoided my calls and just finally told me today that they didn't want to service my unit anymore because there have been too many problems with it. They recommended that I find a different a/c company. Cornerstone is fantastic about taking your money to purchase and install a new a/c unit and sell you a maintenance contract but are incompetent and unwilling to make good on a faulty unit that is still under warranty and that they sold you a service contract for. Cornerstone has been nothing but a VERY EXPENSIVE, time consuming, home damaging headache for me. I HIGHLY suggest not engaging in business with them.
