"Randy replaced my old gas pack at my residence back in 2005. I had three other bids. Not only did Randy offer a higher quality product at a much lower price, he was the only one who pointed out and corrected faulty air send/return ducts from the heating unit to under the house. 
I have had Randy service the unit since then and he again did excellent work at a fair price. 

Highly recommend you call Carter first. They don’t get any better!"
