Best Same-Day Services in Dallas TX

Working with this company has been extremely difficult. You get a window of 4 hours for a tech, he comes out, needs something, schedules another day for a different 4 hour window. Then he says he has to get an approval and will call back. I hear nothing for 3 days so i call in and they try to get me to pay a bill i already paid and i had to provide a check number to prove it. After that they schedule me for an AM appointment, again a 4 hour window (mind you I have had no AC for over a week now). I take off work and wait. Call in and am informed that they moved me to a PM appointment and are sorry they cannot do anything. I ahve to work so have to reschedule again for another mid day window of 4 hours. I would look to another company that can keep time commitments and fix your equipment in a timely manner so you are not out of AC for over a week, including a holiday weekend, and you get a proper window where people actually show up. I cannot comment on the actual work yet as it is not even complete and my AC is still down.
