Best Annual Preventive Maintenance in Raleigh NC

2005 Builder-installed 2nd floor system went out a few years ago. I had so many problems with the same brand on the first floor that I really wanted to have a Trane. The repair Company that I called did not sell Trane brand, so I called Cape Fear. Prompt, clean and otherwise excellent installation experience.
18 months ago I did not have a maintenance contract but they showed up within a couple of hours away for a first floor air-conditioning issue in the hot mid summer weather and quickly fixed it.
Since then I have had maintenance contracts and the fellas that come out put on cloth shoe covers like medical professionals when they come inside.
They are very knowledgeable when I have asked questions about the systems and they spend a lot of time cleaning and checking the systems every six months so that we are not caught off guard by a breakdown. (I think it’s in the neighborhood of 45 minutes to an hour on each system.)
Their technician James has been twice for maintenance Contract service and he is excellent! I can’t say enough good things about him!

I am disappointed by the service. I have a service contract with them. They claim to have mailed me a service card in the mail (which I did not receive) and when I offered feedback, they brushed off a suggestion about a different reminder system.
