I use A Advanced a/c & heat the owners name is Brian Linder ###-###-####. He is great he did some duct work for us last year each estimate we got was $250.00 per duct. He charged me $75.00 great deal. My mother needed to get her a/c, heater, and some duct work done. Her estimates ranged from $16,000 - $8,600, Brains company was the lowest. Everyone tried to sell her a TRAN, but he got her an Amana which came with the exact same warranty as TRAN. He is really good about being honest with you not selling you more expensive name brands just to make more money off of you. Give him a call.
