John...here is a review in your area...this would be a good place to start.
If you were in Georgia, I have the perfect company! Elite Heating and Air. You might want to research them and see if they will come to NC. We had our A/C go out in the dead middle of Summer here and it was 100 degrees. He canceled other appts and came to our house immediately because we have two small kids... he was VERY honest and trustworthy and did a great job. We have a heat pump for our upstairs and he gave us money saving tips for how to cool and heat our house and cut down on our energy bill. It's been a HUGE help!! Good luck! Candice, EXOVATIONS
I recommend Ideal Services. They are based out of Holly Springs, but service the entire area. We have been very pleased with Brian and his crew.
