AC Sizing: Why It Matters

Your air conditioning system plays a major role in staying comfortable in Jacksonville’s hot and humid climate. But did you know that the size of your AC unit is just as important as the brand or model you choose? At All Weather Mechanical Inc., we’ve seen firsthand how proper AC sizing makes a huge difference in performance, efficiency, and overall satisfaction.

Let’s break down why AC sizing matters—and how our team can help you get it right.

What Is AC Sizing?

AC sizing refers to the cooling capacity of your air conditioning system. It’s measured in tons (not weight, but how much heat the unit can remove from your space in an hour). The right size ensures your AC system can keep your home or commercial space cool without overworking itself or falling short.

The Problem with an Undersized Unit

An air conditioner that’s too small for your space will have to run constantly to try to meet your cooling needs. This leads to:

  • Higher energy bills

  • Increased wear and tear

  • Inconsistent temperatures

  • Shortened system lifespan

In Jacksonville, where summer temperatures can easily climb into the 90s, an undersized unit will struggle to keep up—leaving you hot, frustrated, and wasting money on energy you’re not really benefiting from.

The Problem with an Oversized Unit

You might think a bigger unit means better cooling, but that’s not the case. An oversized AC system will cycle on and off more frequently, which can:

  • Create hot and cold spots

  • Reduce indoor humidity control

  • Cause unnecessary noise

  • Shorten system life due to frequent cycling

Plus, those short bursts of cooling don’t allow the system to run long enough to properly dehumidify the air—a major issue in Jacksonville’s muggy climate.
