Hey everyone! I'm trying to figure out if a 3-ton HVAC system will work for my 1300 sq ft single-story home in Florida, which has high ceilings and three bedrooms. I'm looking for advice on whether this size is appropriate, considering the hot summers and possible insulation issues. Any insights would be appreciated!

Getting a professional opinion is key here! A 3-ton unit does fall into the reasonable range for a 1300 sq ft house, especially if you're dealing with hot summers and potentially poor insulation. Just keep in mind that being oversized can lead to short cycling, causing the AC to turn on and off frequently. This can impact efficiency and lead to humidity issues, particularly if you're in a humid climate. So, double-check your insulation and how much sunlight your place gets!
Thanks for the advice! The HVAC tech is coming tomorrow, and we just got a new unit last month. Fingers crossed they can help with these humidity problems.
Sounds like you might need a more thorough assessment! It's common for HVAC pros to oversize systems to avoid call-backs during heat waves. Consider getting a Home Energy Audit done with a blower door test to check your insulation and any air leaks. Also, make sure your attic is properly sealed and insulated. Once you address these issues, see what the HVAC guys recommend regarding unit size.
I can definitely back up the concern about humidity! If the unit is too big, it might not run long enough to dehumidify properly, leading to that musty smell, especially if you have carpet. In my case, I went with a 2-ton system for a 1660 sq ft house and have had no cooling issues during really hot days.
