HVAC Feedback appreciated -

The one thing to remember with Carrier is that it uses Pureon freon, very costly and runs twice the pressure. Trane may have been sold a few times buy so has everyone else. The trane scroll compressor is still one of the best in the industry. Must of your units use copelan compressors, furness contactors ect. checki the compressor warranty, firebox warranty, and main board warranties they are your most expensive parts to replace. I like American Standard/Trane as I have had fewer call backs then any other brand. As stated be sure of your installer, you could have the best unit made and if not installed correctly, it can be noisy, less efficent and give you many head aches. Also Do NOT let them install a new condenser and A coil set Without running a NEW Line set!
