HVAC

[EvinFord]

Alright guys, I need some help. I know nothing about HVAC systems and I am in need of a completely new system. My wife and I bought a house and the AC and Heater are very old and need to be replaced. The house is around 1600 square feet and everything will need to be replaced, the outside unit, inside unit and heater. How large of a unit will I need to get and how much should I expect this to cost? I have an idea but want to get some opinions first. I have always heard go bigger than you think you will need because you always want to be a little overpowered the underpowered when it comes to AC units.

Also, I am looking for a good quality HVAC company to come out and give me a quote, any recommendations in the Baton Rouge Area?

Thanks in advance.
