If you’re like the majority of homeowners, you’ve probably never given much consideration to how your central HVAC system works. As long as it keeps your home cool in the summer by producing cool, conditioned air, chances are you don’t care how it does it–at least not until it breaks down unexpectedly.

Most homeowners see their central air conditioners as unnecessarily complicated equipment that only a skilled HVAC expert can comprehend. The usual air conditioner is made up of four major components: the evaporator coil, compressor, condenser coil, and expansion valve. Each component contributes to your central air conditioner’s ability to deliver cooling comfort in your house.

Know more about the components of your central HVAC system and how they help your comfort unit give you the best air quality in your home.

  • The Evaporator Coil

The evaporator coil, which is located inside the air handler of your central air conditioner, plays an important function in keeping your house cool and pleasant. The evaporator coil, which is lined with thin aluminum fins, resembles and acts nearly exactly like a vehicle radiator, except that it absorbs heat rather than reject it.

When the cold refrigerant reaches the evaporator coil, it absorbs latent heat from the air moving through it. Capturing this thermal energy causes the refrigerant to change from a chilly mist to a heated vapor. Meanwhile, the air that travels through the evaporator coil loses heat and moisture, resulting in the cold, dry air that is distributed throughout your home via ductwork.

  • The Compressor

Your central AC’s compressor is its heart. It would be hard to keep your house cool and pleasant without it. The compressor for your central air conditioner is located in the exterior cabinet, next to the condenser coil.

The compressor, as the name indicates, takes in heated refrigerant vapor and compresses it into a denser form. This procedure also raises the temperature and pressure of the refrigerant, making it hotter than previously. Finally, the compressed refrigerant is forced through the condenser coil.

  • The Condenser Coil

The condenser coil, like the evaporator coil, is critical to the operation of your central AC. The condenser coil, unlike the evaporator coil, is responsible for releasing heat from the refrigerant. Consider your car’s radiator, which is meant to disperse heat generated by the coolant moving within.

In fact, it works in much the same way as the evaporator coil. A condenser fan integrated into the outdoor cabinet distributes ambient air through the condenser coil in the same way as the built-in fan in the inside air handler moves air through the condenser coil. Instead of accumulating latent heat, the condenser coil expels heat from the refrigerant via the airflow.

  • The Expansion Valve

There’s not much your central AC can do with liquid refrigerant. It will not be able to absorb latent heat when it cycles around the evaporator coil in its current state. To finish the air conditioning process, the refrigerant must be converted back into a chilly mist. The expansion valve comes into play here.

The expansion valve turns the flow of liquid refrigerant back to vapor form. The liquid refrigerant enters the valve through a very small hole that is designed to meter the amount of refrigerant that flows through. A temperature-sensing bulb aids in modulating refrigerant flow based on suction line temperatures.

Expenses You May Spend to Install a Central AC System

In most areas where temperatures may rise throughout the hot season, air conditioning is considered a necessity. If your central air conditioner is more than 10 to 15 years old, your energy bill for cooling your house is more than normal, or the air doesn’t feel as chilly as it used to be, it’s time to replace it.

Central air conditioners are the most common way to circulate cool air throughout the home, and the cost of installation varies based on the size of the home and unit. Installing a central air conditioner in an older home may be more expensive than installing one in a new one.

It is critical to understand the alternatives for residential air conditioning before making a decision to install it since there are many factors that influence the price, including the type of unit purchased, the size and energy efficiency of the unit, and the layout or structure of your home.

The overall cost of a central air system is determined by a number of factors. The size of your unit is very crucial to consider. Additionally, the cost of a central air conditioning unit is influenced by a few key factors: the quantity of ducting required, the size of the unit, the Seasonal Energy Efficiency  Ratio (SEER) rating, and any necessary repairs.

Here are the typical costs of an air conditioning unit, including installation, which varies by size:

AC Size Average Cost
1.5 ton $2, 500 – $4, 500
2-ton $3, 100 – $5, 100
3-ton $3, 400 – $5, 400
4-ton $4, 200 – $6, 200
14 SEER $3, 000 – $6, 000
16 SEER $3, 700 – $9, 000
