Best Air Conditioners Heat Pumps in Durham NC

I do not plan to use this service again. My unit is fine but 2 out of the 3 times they have visited there was something wrong that was$300+! My system works fine it was 8 years new when there was a supposed problem. Plus they were scheduled for 11-2 and called at 9:30 to say that someone was in route on my voicemail! I was totally shocked when the guy was ringing the doorbell at 10:15 while I'm getting out of the shower. What's the purpose of scheduling an appointment if you are coming when you get ready! The initial salesperson is a real nice guy but it hits the fan when it gets past him! Won't use it again!
