Best Central Air Conditioner in Dallas TX

I would not recommend this company to anyone! They have a national call center that answers their phones and the reps do not have access to any owner account. They ask you to repeat all of your account information each time because they cannot see your service details or account details. Company gave me a 2 hour window and did not even call to let me know they were running several hours behind. They gave me a window of 1-3pm or 3-5pm (which I was to choose) and no one called me when tech was running ours behind. I called the company to find out where the tech was. The tech that came to our home was beyond rude. And then the price was 3x more than others in the area. I would never use this company! When I asked to speak with a manager, they said that had no phone numbers or emails of anyone to contact but the 'Manager' will call you back. I asked for a 'Manager' to call back yesterday and then never did. I called again today with the exact same script given to me. You cannot cancel any appointments with the without speaking to a 'Manager' and good luck getting a hold of any 'Manager.'
