Central air is a feature in US homes. The cost to install central air and other cooling options depends on house size and location. An AC system provides air from a main source and distributes it via fans and vents.
The air system has an outside compressor that’s attached to the home which generates air.
How Much Does It Cost To Install Central Air?
The biggest question regarding central air is “how much does it cost?” It seems like a dream to cool your house with one ac unit.
The cost ranges between $3,000 to $7,000. Why is this the price and how can you lower the cost?
Evaluation – Under $500
It may be tempting to skip an evaluation, but it will save money. You want to get the right central air unit. You don’t want to overpay for something you don’t need.
Type Of Central Air Unit – $1,400 to $4000
The type of central air unit matters. However, most contractors or HVAC installers will help you decide what’s right for you. Heat pumps are expensive, but they can also heat your house. Whereas split air systems are cheaper but work one way.
The size of the unit you choose also matters. It cost more to buy a unit that heats a 3,000 square foot home than a 1,000-square foot home. The last thing that affects the cost of the unit is the brand name. A Lennox unit will be twice as much as Coleman.
Labor – $400 to $2,000
The cost of labor depends on whether you need ducts installed or not. If you don’t, you can pay as little as a few hundred dollars. If you do, you may pay up to $2,000. This means about a third to half of what you pay will be labor.
Some people try to install central air themselves, but this will cost more money in the end. Repairs can add a lot to your cost. With half of all AC units being installed wrong, you can reduce the efficiency by 30 percent or more.
Pros And Cons Of Central Air
In the end, it all comes down to the pros and cons.
- No Maintenance – If installed by a pro, expect to leave the central air for decades without having to fix it. You need to watch out for mold and mildew in the ductwork.

- Natural Filter – Central air units clean and filter the air. Dust and harmful particles are removed from air without the need for another air filter.
- Expensive – AC isn’t cheap. You will spend a few thousand dollars, which is more than other systems.
- Energy Hog – Central air uses energy and can raise your power bill. It’s not the most energy-efficient way to cool your home.
- Can’t DIY – If it needs repairing, cleaning, or installing, call a pro if you have central air. This will add to the cost of cooling your home as labor isn’t cheap.
- Overshared Air – AC units ensure an entire home is at the same temperature.
Other Cooling Options
Central air isn’t the sole option for cooling your house. The other option doesn’t have to be a basic fan either. Those can work for cool climates, but most homes need something stronger. These days, there are dozens of ways to cool a home.
Window AC Units
Window air conditioning units are one of the cheapest ways to cool a room. Just like central air, window ac units come with a list of pros and cons.
- Cheap – This is the cheapest way to cool a home. Window AC units are affordable, and they work for the room they are installed in.

- Can change window – You can move AC units to different windows in your home. When you move the unit, reinsulate it.
- Cools one room – Window AC units aren’t made for entire houses. You can add one to each room but then this makes the cost that much more. They are better for smaller houses that need one or two.
- Can be hard to insulate around – AC units need an open window. This can cause problems. You need AC insulation. This doesn’t raise the cost.
- Needs a strong window frame – Some frames can’t support an AC window unit. The windows won’t work without a frame. For homes without good windows, a different type of unit is necessary.
- Unsafe if not installed right – Units have been known to fall out of windows. It’s best if someone who knows what they are doing installs it for you. A frame may need to build for extra security.
- Security risk – The units are easy to move, so they pose a security risk. You’ll need a home security system if you have a window unit. Make sure it covers windows and doors.
Standing AC Units
Also known as a portable AC unit, these are the easiest air conditioners to install. You plug it in and you’re good to go.
- No installation needed – You can take it home and plug it in. Some require a tiny bit of setup but it’s easy and can be done by anyone that can read a manual.
- Cheap – This is one of the cheapest AC options available. You can get a good one for less than a central air system or a small one for the same price as a heater.

- Out of sight – It’s safe to put these units behind furniture or a curtain. You can hide them, and they’ll keep a room cool.
- Loud – Portable AC units can be quite loud. While quiet options are available, most of them are noisy and can be annoying if you don’t like a lot of white noise.
- No outdoor heat release – Because standing AC units don’t allow heat to escape outside, it can counter inside. The heat can’t escape and makes it harder to cool the room.

- For small areas – Portable air conditioners are for small areas. You can use them to cool a room, but that air isn’t l to travel far outside the room. You’ll need one for the rooms you want to cool.
An evaporative cooler, or swamp cooler, is for outdoor. It turns water into cool air. This is an eco-friendly, though a less effective way to cool.
- Energy-efficient – Evaporative coolers use water and cool with humidity. They save money and reduce any bills you may have associated with cooling your home.
- Eco-friendly – They recycle water, evaporative coolers are eco-friendly. If you’re going off-the-grid or want a more natural lifestyle.
- Great for mild climates – If the temperature never gets above 90 degrees where you live, then evaporative coolers may cool your home.
- Not for hot climates – If your climate gets over 95 degrees, then evaporative coolers won’t work. You want it to stay mild. It can’t make a room more than 20 degrees cooler than it is outside.
- Not for humid climates – These systems use humidity to cool a room, so using them in humid climates will make the room hotter.
- Other systems more effective – Evaporative coolers are one of the least effective methods for most climates. In the future, they may be the number one type of cooling unit, but now, they don’t work in most cases.

Mini-Split Air Conditioners
Mini-split units heat and cool, which is why they are becoming popular. But just like other cooling options, they have both pros and cons.
- Small – mini-split ACs are small and don’t take up a lot of room. They are noticeable but they aren’t as large as other AC units, yet they cool the area just as good, perhaps even better than standard AC units.
- Heats and cools – Mini-splits heat and cool a home. You won’t have to pay for a heating system. You won’t have more than one system to take care of.
- Separate systems – many mini-splits have multiple units connected to an outdoor unit. You can use them when needed and turn them off when you want.
- Easy installation – though installing a multi-split isn’t as easy as using a portable AC, it’s much easier than installing central air. You don’t need to use any ducts and a small conduit.
- Multiple ways to mount – mini-splits are mounted on a wall, hung from ceilings, or in a window. There are many ways to install them so you can set them up to match your room.
- Secure – because they need a small hole, they are more secure than other mounted units or window units. So, no one is crawling in even if they do manage to get the unit out.
- Medium-priced – though they don’t cost as much as central air most of the time, they do cost more than most other cooling systems.
- Not invisible – you can’t hide them like other units or central ACs. If you don’t like how they look, you’re out of luck.
- Requires a pro – you shouldn’t attempt to install mini-splits alone. Since they are new and upgrading, it’s best to call a pro. If you don’t, you risk your safety and lose money on repairing mistakes.
Air Condition Filters
If you have allergies or suffer from asthma, you will need to pay attention to your AC filters. An AC unit cleans the air inside your home. When the air enters your home, allergens have been removed from it.
Changing your AC filter is vital. If you have pets and one person with allergies, change the filter every 20 to 40 days.
There are a few types of AC filters to consider.
- Fiberglass filters are cheap and will protect your AC unit. The problem is they’re not the best at purifying indoor air.
- Pleated filters are polyester or cotton. They’re great for blocking harmful air particles that trigger allergies. You can wash them and use them multiple times.
- HEPA (high efficiency particulate air) filters are the strongest and best at blocking harmful air particles. They’re also known to accumulate dust and mold.
