What is the Central Air Value?
The term central air conditioner usually refers to a split system composed of outdoor and indoor units. The outdoor unit is commonly used as a metal cabinet that serves as the housing for the compressor and the condenser.
This metal cabinet is connected to the indoor unit with a series of pipes that allow the air and the refrigerant to flow between the two components. In addition, the system’s evaporator that is responsible for generating cool air is located in the indoor unit.
The variation of this system called the packaged central air conditioner features only the outdoor unit that houses the condenser, compressor, and evaporator.
This type of central AC unit has to be connected to the duct system that protrudes through the structure’s external wall, which is why it is usually installed on buildings that already have a duct system.

The Coverage Area of 4-ton AC Units
The amount of space you can cool with a 4-ton AC unit depends on the climate you live in. So, if you live in a cold climate, you can use this system to cool to 2,400 sq/ft area, while its coverage range drops to approximately 1,900 sq/ft in regions with moderate climates.
In warm climates, these systems can’t cool spaces larger than 1,600 sq/ft, and given the fact that the average size of a single-family house in the United States is around 2,400 sq/ft, you must make sure that a 4 -ton AC unit is powerful enough to keep your entire home cool.
Getting an AC unit that is too large for your home is just as bad as choosing a system that isn’t big enough because, in either case, the system needs high amounts of power to maintain a constant temperature in all rooms.

Energy-Saving Features of 4-ton AC Units
High utility bills are one of the most common side effects of inefficient cooling systems. That’s why you should pay close attention to the unit’s energy efficiency ratings.
The Seasonal Energy Efficiency Rating or SEER shows how much energy the unit needs to consume during the cooling season to maintain the room temperature at the same level during that time.
The energy efficiency ratio or EER shows how much power an AC system needs every hour to achieve its maximum cooling capacity measured in British Thermal Units (BTUs).
Choosing a model that is Energy Star certified is probably the easiest way to ensure that your cooling system will consume too much power. However, you should bear in mind that the unit’s efficiency can be affected by your home’s insulation and numerous other factors.

The Durability of 4-ton AC Units
The quality of central air conditions varies depending on the brand and the model, only the basic single-stage AC is considerably less durable than a high-end variable speed cooling system.
Manufacturers like Goodman , Payne , or AIRE-FLO are generally considered budget brands whose models aren’t stacked with features offered by Amana , York , or Trane brands.
Nonetheless, most 4-ton AC units can remain functional for more than ten years, although all models require maintenance regardless of how much they cost.
Refrigerant leakage or corrosion is more common on entry-level systems because they don’t have water-resistant outdoor components, which can ultimately cause the metal parts to rust and leak.
Central 4-ton ACs don’t have high upkeep requirements as maintenance checks are usually performed once per year. Go through our guide to the best GE portable air conditioners if you don’t want to go through the trouble of installing a 4-ton AC unit in your home.
Installing a 4-ton AC Unit
The complex ductwork or connecting the system’s outdoor and indoor components are overwhelming tasks for skilled and experienced DIYers. That’s why you have to hire a licensed contractor to install a central 4-ton AC unit in your home.
Depending on the system’s complexity, it takes between 4 and 8 hours to complete the installation process. The installation of a central air conditioner can cost between $1,000 and 10,000, and the service can be even more expensive if your home doesn’t have existing ductwork.
In addition, you’ll have to acquire the permit to install a 4-ton AC unit through the contractor you choose before the installation process can start. The cost of acquiring this allows is usually added to the overall installation costs.

Factors to Consider While Choosing a 4-ton AC Unit
You shouldn’t choose a 4-ton AC unit by yourself, especially if you’re not familiar with all aspects of these cooling systems. Instead, you should consult with a contractor every step of the way and make sure that the model you choose is a good fit for your home.
This doesn’t mean you should let the contractors make all the decisions for you, but rather that you should work with them on finding an optimal cooling solution for your house, and to do that, you’ll need to pay attention to a wide range of factors.
We’ve shortlisted some of the most important ones, so let’s take a closer look at them.
The Size of Your Home
The coverage range of 4-ton ACs ranges from 1,600 sq/ft in warm climates to 2,400 sq/ft in cold climates. If your home is smaller or larger than the coverage range of a 4-ton AC unit, you should search for a model with a higher or lower tonnage.
The unit’s coverage is largely affected by the climate, which is why you should ask the contractor if a 4-ton cooling system is a good solution for your home. You should also factor in the structure’s insulation because poorly insulated spaces are generally difficult to cool.
You can choose between single-stage, dual-stage, and variable speed compressor types. As their name implies, single-stage units operate constantly, and you can’t lower their output. Consequently, they consume more power than dual-stage units that let you adjust their current output.
Variable speed central ACs grant you complete control over their output as they can offer up to 700 compressor settings.
Such a wide variety of output options allows for a gradual increase or decrease in airflow. It boosts the unit’s energy efficiency since you don’t always have to use it at the maximum capacity.
ACs are not loud because they generate a similar noise as vacuum cleaners, washing machines, or hairdryers. The quietest models are slightly louder than a refrigerator or an electric toothbrush, while the loudest models are as loud as a coffee grinder.
You should opt for a unit that produces between 50dB and 60dB if you want to make sure that the central AC isn’t going to disturb your neighbors. Units that generate more than 70dB of noise are better suited for households with large backyards or commercial buildings in non-residential parts of the city.
4-ton AC Unit Brand
The quality of a 4-ton AC often depends on the manufacturer, so you shouldn’t expect the same level of performance from all brands. However, comparing models produced by different brands will enable you to find the most reliable cooling solution for your home.
You should keep in mind that the performance of a 4-ton AC unit depends on its features, so going through the model’s specification list is going to help you understand the model’s capabilities.
However, units equipped with high-end features cost significantly more than central ACs with a basic set of options.
Cost and Warranty
Even the least expensive central AC units cost more than a thousand dollars, while you can spend more than $3,000 on a high-end model. In addition, the installation costs of these units are incredibly high, and in some cases, you may have to spend more than $10,000 just to install the AC switch.
The length of the warranty depends on the manufacturer, but most brands offer 10-year limited warranties. You should search for a model that is covered by a warranty that includes free replacement or repair of broken components.
The Advantages of 4-ton AC Units
Great Coverage Range
These units are designed to supply cooling to large venues and homes. Their coverage range helps you avoid installing separate AC units in different parts of your home. In addition, you can control the entire cooling system with just one thermostat.
Long Life Span
Even the least expensive 4-ton AC units last for more than a decade, while in most cases, these cooling systems remain functional for more than 20 years. Moreover, you won’t have to spend time on their maintenance as the contractor that installs the unit is usually in charge of their upkeep.
Excellent Energy Efficiency
Opting to install a 4-ton central AC unit in your home will save you hundreds of dollars on utility bills every year. In addition, most models have SEER and EER above-average ratings and Energy Star certifications that vouch for their high energy efficiency.
The Disadvantages of 4-ton AC Units
High Price Tag
Obtaining and setting up a 4-ton AC unit is likely to cost you several thousand dollars. These cooling systems are far from being budget-friendly, and you should search for alternative options if the cost of the AC switch exceeds your budget.
