There are many choices, like central air, ductless mini-split, window units, portable models, floor-mounted systems, smart ACs, geothermal systems, and hybrid units. Each type has its own features. Knowing the Types of Air Conditioner helps you choose the best one. Are you ready to see which one is good for you?
Key Takeaways
Pick the best air conditioner for your room size, money, and how cool you want it. Central air is good for big houses. Window units are better for small rooms. Ductless mini-splits use less energy. They let you control each room’s temperature. Smart ACs are easy to use with a remote. They help save energy too. Think about how much care and setup will cost when you choose an air conditioner.
Types of Air Conditioner
Central Air
Central air cools your whole house. It sends cool air through ducts. Every room gets the same temperature. The air handler sits in one spot. Fans push air through the ducts.
Central air is good for big homes.
You can heat or cool many rooms at once.
Fans help spread air everywhere.
Most systems use CAV or VAV for better control.
💡 Most people pay about $7,000 to put in central air for a 2,000-square-foot house. The cost is usually between $5,000 and $12,000.
Ductless Mini-Split
Ductless mini-splits give you cooling without ducts. They fit almost anywhere. These are great for new rooms or old houses.
You can put them in rooms that need more cooling.
Mini-splits stop energy loss from leaky ducts.
They run quietly, so you hardly hear them.
Filters clean the air and catch dust.
You set the temperature for each room.
Ductless mini-splits save more energy than central air. They cool only the rooms you use. This means lower bills. They often have higher SEER ratings, which show better energy use.
Window Unit
Window units are easy and popular. You put them in a window and plug them in.
Here are some models and where they work best:
Model | Unique Features | Best Environments |
---|---|---|
Midea U-Shaped MAW08V1QW | WiFi control, easy mode changes | Smart home integration |
LG Smart LW1022FVSM | Remote control, smart capabilities | Rooms needing remote access |
Frigidaire FHWC084WB1 | Child lock system, air direction | Family homes with children |
Black+Decker BD08WT6 | Timer via remote, effective controls | Limited window access |
Midea EasyCool MAW05M1BWT | Simple controls, effective cooling | Budget-conscious users |
Window units work best in small rooms or apartments. You can find models for tech lovers or people who want simple cooling.
Prices go from $150 to $1,500, so there is one for almost any budget.
Portable Unit
Portable air conditioners move with you. You roll them to different rooms and vent them out a window.
Single-hose models cool small spaces up to 400-500 sq ft. They work best where air does not leak much.
Dual-hose models cool bigger rooms faster, especially in hot places.
Evaporative coolers use water instead of refrigerant and work best in dry areas.
Room Size (sq ft) | |
---|---|
8,000–10,000 | Up to 300 |
12,000–14,000 | 300–500 |
Over 14,000 | Large rooms or open spaces |
Portable units are good if you rent or do not want to install something permanent.
Floor-Mounted
Floor-mounted air conditioners sit on the ground. They plug into a window for venting.
Feature/Scenario | Description |
---|---|
Mobility | Move easily between rooms |
Ideal for Small Spaces | Perfect for apartments or single rooms |
Humidity Control | Good for hot spots or high humidity |
Cost-Effective | Cheaper than central or ductless for one room |

Less Energy Efficient | Higher energy costs than other types |
Limited Cooling Capacity | Best for small to medium spaces |
Space Requirements | Can be bulky, needs window access |
Pick this type if you want fast setup and do not mind extra bulk.
Hybrid/Dual Fuel
Hybrid or dual fuel systems use a heat pump and furnace. They switch between electric and gas, depending on the weather.
Advantage | Description |
---|---|
Energy efficiency | Uses heat pump in mild weather to save energy |
Cost savings | Cuts heating and cooling costs over time |
Consistent comfort | Keeps indoor temperature steady |
Environmental impact | Uses less fossil fuel, better for the planet |

Smart air conditioners connect to your phone or smart home. You control them from anywhere.
Automated systems save energy and lower costs.
You set custom temperatures for each room.
Remote access lets you change settings anytime.
Maintenance alerts remind you to change filters.
Smart ACs can save you up to 15% on cooling bills. You get comfort, control, and peace of mind.
Geothermal
Geothermal air conditioners use the earth’s temperature to cool your home.
These systems use underground pipes to move heat in and out.
You get lower energy bills because geothermal uses 34% less energy than regular AC.
The Department of Energy says you can save 20–50% on energy compared to standard HVAC.
Geothermal works best if you want long-term savings and care about the environment.
Evaporative Cooler
Evaporative coolers use water to cool air.
They work best in dry places like the southwestern USA.
You need a steady water supply.
They do not cool as much as regular AC, but they use less energy.
⚠️ Evaporative coolers do not work well in humid places. High humidity can cause mold and dust mites, making things uncomfortable.
Through-the-Wall
Through-the-wall air conditioners fit into a hole in your wall, not a window.
Pick an outside wall with no wires or pipes.
Use a stud finder to find supports.
Cut a hole for the AC sleeve.
Frame the opening for support.
Slide in the AC and seal the edges.
These units save window space and use less energy than window units.
You get better cooling and less noise.
