Of course, the price tag will vary depending on the type of system you wish to install, the size and location of your household, and whether you have air ducts or you wish to install them from scratch.
Things That Affect the Overall Expenses for Installing HVAC System
The price of the AC unit is just a piece of the puzzle that you should consider and implement.
The next step is to pay for a pre-installation evaluation, air duct installation or repair, finding a qualified contractor that will handle all HVAC system issues, and installation of everything you need.
1. Pre-Installation Evaluation
The first step that you should make is to understand the Manual J load calculation. This particular calculation will determine how much heat your house will gain throughout the day, which will determine the size of units you should get along the way.
Remember that energy audit can cost a few hundred dollars, depending on numerous factors. Of course, some companies may offer you both rebates and discounts, which is something you need to remember.
In the best-case scenario, the load calculation will be part of the audit. At the same time, the assessment will determine the potential issues and air leaks that will increase the expenses you should consider for getting an AC.

An energy audit can cost several hundred dollars, but your utility company may offer discounts or rebates. After handling this particular calculation, the contractor will check the systems, such as ductwork, to determine whether it can handle the central AC unit.
If the existing ducts cannot handle the airflow of the latest AC unit, you may also lack a space to put a refrigerant line to the exterior, especially if the room does not come with properly-sized vents.
As a result, you will have to include the costs for making a new system based on both modifications and upgrades that you wish to implement. That way, you will reduce high-energy expenses and other problems that may happen along the way.
2. The Central AC
As soon as they evaluate both support systems and home performance, you need to find the proper AC unit that will meet your needs and preferences. Everything depends on the structure and size of your home, which is why you should understand the common types such as:
- Split Air Conditioning Systems – Keep in mind that these units come with three elements, including the air handler, evaporator coil, and condensing unit. The condensing unit goes outside, and it is like a large metal box with a fan. The air handler and evaporator coil are inside. A split system is the best choice for people with low budgets because they are economical, quiet, effective, and affordable.
- Packaged Central Air Systems – These systems are similar to split ones, except everything is inside a single box, which is located next to the foundation or on the roof. They are not as famous for residential purposes unless you cannot fit the split system, especially since you will not get the same level of efficiency.
- Heat Pumps – You should know that they act as both furnaces and AC units at the same time, but they are not for areas with extreme weather conditions. Therefore, you should use them in areas with mild climates. Keep in mind that a heat pump will extract hot air from your household and dump it outside during the summer days while it will pump the heat inside during the winter days. It is a useful option, especially if you combine it with a gas furnace you already own.
Apart from the idea that the price depends on the type, it also varies based on the size you wish to get.

Remember that AC capacity is measured in tons, which means that the residential system should go between 1.5 and 5 tons.
However, more significant is not always better, because the AC unit size should depend on the previous calculation we have mentioned.
