Hello everyone,

I own an approximately 1600 sq ft townhouse that is 17 years old. The HVAC system is original to the home (Comfort Maker). I have gotten bids from 3 independent companies. With all the options, I could really use some input regading which system is best.

Company A: 3 different proposed setups. Each one include replacing the condenser lines.
