Out of curiosity what should the humidity be in a house ? The thermostats I have can be programmed to lower humidity.

People have Ac in places like Vegas with extremely low Humidity.

I agree with the others that said that you don’t want too big of a system, but I’m sorry it’s laughable to suggest that 6 tons is too big for a 2550 sq ft house with 10 ft ceilings. There’s about 50 variables and if one or 2 are off and you are cutting it close you could be unhappy. It’s probably about $600-700 bucks to go up a half or full ton just to guarantee you are staying cool and not overworking your system. It gives you wiggle room for additions and whatever else also.

Hvac systems are like trucks, everyone has a brand they love and hate. You never know when there will be a recall or lemon for a unit. Just go with your gut but make sure you get multiple suggestions at least 3.
