How a 4 Ton AC System Works

How It Works

Step 1

The indoor unit draws warm indoor air across the evaporator coil, where heat is absorbed by the refrigerant.

Step 2

The refrigerant carries the absorbed heat to the outdoor condenser through the refrigerant lines.

Step 3

The outdoor condenser releases the heat outside before the cooled refrigerant returns indoors to repeat the cycle.

A properly matched system will help you maintain reliable cooling performance throughout the warmer months.

What Does “Equipment Only” Mean?

Equipment-only means that you are purchasing the HVAC equipment without any installation services. Depending on our current inventory, you can choose a complete 4 ton AC unit or individual components such as a 4 ton AC unit condenser or 4 ton AC unit evaporator coil, but installation is something you must take care of.

This option gives homeowners, landlords, property managers, and contractors the flexibility to replace only the equipment they need rather than replacing entire HVAC systems, while staying within budget. You can simply pay for the equipment without paying additional charges for installation.

What Size AC System Do I Need? Is a 4 Ton AC Unit Right for My Property?

The cooling capacity of a 4 ton AC unit is equal to 48,000 BTUs. This is one of the ideal sizes for properties that are relatively larger in size and have a greater demand for cooling.

Ideally, it is said that for properties located in Florida, there should be one ton of cooling capacity for every 400 to 500 square feet of property. However, due to the erratic climatic conditions in Southwest Florida, it is always better to conduct a professional load calculation to ascertain the right tonnage.

Note: These sizing ranges are general estimates only and should not be used as a substitute for a professional load calculation. Every property is different, and their different composition factors such as insulation, ceiling height, window area, and sun exposure can significantly affect the equipment size required.
