How to Make an Air Conditioner Colder

For many people, winter brings about a change in their living conditions. Some are forced to move south for the cold weather, while others crank up the thermostat to stay warm. But what if you could have it all? What if you could precisely control your temperature and not break the bank on cooling costs? Consider an air conditioner that can go colder than standard units!

The most common reason your AC would not be as cold as usual is because of an issue with the refrigerant in the unit. This will need to be replaced by a certified technician who has experience working on these systems.

If you want to keep up with maintenance so this doesn’t happen again, we recommend having routine tune-ups done at least twice a year. Here we have given some tips on how to make an air conditioner colder so you don’t feel like you’re living in Hell anymore. 

How to Make an Air Conditioner Colder

10 Reasons Why You Should Make an Air Conditioner Colder:

Here are some reasons we have discussed why you should make an air conditioner colder before you know how to make an air conditioner colder.

1. Energy Efficiency:

An air conditioner needs to be on to keep your room cool. However, if the temperature is already cool (say 60 degrees), then the AC doesn’t need to continue running because it wastes energy and money.

2. Comfort:

Often, when people don’t want their air conditioner on, they crank up the heat. Unfortunately, turning on the heat is not an option for those who already live in a colder climate. So how do we keep your houses cool? Opening windows and doors brings in hot air from outside.

3. Health:

Humidity can influence your well-being. For example, when humidity levels are too high, it can cause you to feel tired. In addition, the heat from your AC will add to the humidity levels in your home, which is not healthy for anyone suffering from respiratory ailments such as asthma and allergies.

4. A/C Unit Health:

When an air conditioner is constantly running, it can break down because it needs too much work. Instead of forcing the A/C unit to work extra hard by making it run for long periods, turn your AC off when you don’t need it. The A/C team will have to work less, saving you money in the long run.

5. Less Humidity:

When your AC unit is always on, it’s constantly running and dripping water inside your home. Without a constant flow of cold air circulating throughout your house, the humidity levels rise, which causes mold to form.

6. Fewer Dust Mites:

Dust mites do not like dry weather; they prefer warm and humid climates where they can breed. Therefore, turn off your AC unit when you’re not at home to keep the humidity levels low, reducing the possibility of dust mites growing in your home.

7. Preserve Your Wood Furniture:

If you have expensive or antique wooden furniture, you will want to keep it in its best condition possible. Leaving the AC on all the time will cause moisture to build up, damaging your wooden pieces. Turn off your A/C when you’re not home to prevent this problem from occurring.

8. Optimize the System:

When you turn off your AC unit when you’re not using it, the system’s overall efficiency increases. The AC will need less work to keep your room cool whenever you turn it on, so all its energy won’t be wasted while idle.

9. Longer Machine Life:

If the moving parts in your AC unit aren’t constantly under stress, they will most likely last longer. So instead of forcing your AC to work overtime whenever you turn it on, just let it take a break and turn it off.

10. Save Money:

Your AC unit is one of the most significant energy expenses you have each month; running an air conditioner costs a lot of money and costs you Money to buy the unit. To save as much as possible, turn off your AC when you’re not at home or when you’re sleeping.

10 Ways on How to Make an Air Conditioner Colder:

10 Ways on How to Make an Air Conditioner Colder

Here we have mentioned some ways how to make an air conditioner colder. Be sure to follow these steps.

1. Clean the Filters:

The dust that accumulates on the filters reduces the airflow, which means your air conditioner has to work harder. Cleaning them will make it easier for the system to keep you cool. It’ll also help you save money since dirty filters force your unit to run longer and use more energy than needed

2. Check for Leaks:

If your home is losing cool air, it’s a sign that the unit isn’t as effective as it once was. In addition to opening windows and doors, check for leaks around the edges of exterior walls or near utility penetrations where sheet metal is crimped onto small screws that hold joints together.

Make sure all seams are completely sealed and that all screws are tight. You can also caulk small gaps or spaces to prevent warm air from seeping in. This is a common problem, so there’s no need to be embarrassed.

3. Check the Temperature:

Don’t set the thermostat at 80 degrees and call it good you’ll only pay more for cooling and lose comfort. The best place for your thermostat is in the central part of your home, probably on an interior wall or ceiling close to where you spend most of your time.

To see if the system is working efficiently, check the temperature at various locations throughout your home with a thermometer before heading off to work in the morning.

This is especially important if you’re in an older home with inadequate Insulation or single-pane windows, which lose more heat than newer homes. Adjust the temperature setting up or down until you find a comfortable temperature for your family while still keeping energy costs at a minimum.

4. Keep Windows Closed:

When the sun beats down on your house, it heats both the inside and outside air. So if you’re home during the day, keep windows closed. If you want some fresh air in your house at night, open them then to take advantage of cooler evening temperatures.

5. Adjust Your Thermostat:

Set back the thermostat when you’re going to be away from home for a while. If you have a programmable thermostat, which allows you to pre-set it to turn on and off at different times of the day or night, use it! Set your thermostat higher in the morning and just before bedtime in the summer months. Set it lower when you get up and turn it back a bit before bedtime in the winter.

6. Dry Clothes Indoors:

Drying clothes on an outdoor line makes them crisp and fresh. But if your air conditioner is running throughout the day to keep up with all that drying, you could be wasting energy and Money. If it’s a nice day, dry your clothes outside and let the breeze do some of the work for you. Or hang them up to air dry without using the dryer at all. Nothing beats natural drying on a breezy day!

7. Check Your Air Seals:

During the winter, cold air can seep around windows and doors. This will increase your heating bill since you’ll have to compensate by turning up the heat. To stop leaks, caulk cracks between windowpanes, weatherstrip around the exterior doorjamb, check caulking dry rot or cracking, air toward the center, and ensure all air vents that lead into your house are sealed.

8. Check the Condenser:

It’s your outdoor unit’s location, usually at the side or rear of your home. Make sure there’s no debris around it, like leaves and fallen tree limbs. Check the coils on top to ensure they’re not covered with dirt or caked with ice (which restricts airflow). Check if connections are loose, screws corroded, or if it looks damaged.

9. Clean Any External Grates:

If you have a central air system where hot, cooled, or even warm air from within the house is pushed through exterior grates, ensure they’re clean and free of debris. If they’re blocked, cool air will stay inside.

10. Add Insulation:

Adding Insulation to the attic or walls is a great way to keep cool air inside your house during the summer months. Check your insulation levels with an insulation meter, and if it’s below-recommended levels, beef up those areas! Most utility companies offer rebates for this home improvement project.

Some Tips and Tricks:

Tips and Tricks to Make an Air Conditioner Colder

1. Change the air filter every three months or more frequently if it is dirty. This helps keep your AC running efficiently and will save you money by having to purchase a new one less often.

2. Clean the coils on an air conditioner outside your house at least once a year to make the unit work more efficiently.

3. If you have a portable air conditioner, make sure the exhaust hose is not blocked in any way.

4. If you use an air conditioner that works with your window, ensure it is adequately sealed by closing and opening the window when running the unit to ensure no gaps between the window and frame.

5. Make sure all windows are opened in rooms with an air conditioner when it is running. This helps allow cold air to circulate throughout the room instead of just sitting in one area.

6. Avoid turning off your central air conditioning by closing vents that lead to other areas in your house, such as bathrooms or garages. This will cause the unit to run longer, which will cool the space more efficiently.

7. Ensure windows are adequately sealed with blinds or curtains to reduce heat transfer from outside air into your house during daytime hours when the air conditioning is usually running.

Precautions and Safety Measures:

1. Never try to make an air conditioner colder by putting it in the fridge.

2. Never put anything inside the AC to make it colder. This could cause damage or injury.

3. Keep all flammable items away from the AC.

4. Make sure to turn off and unplug the AC before you do any maintenance or repairs on it.

5. Keep pets and children away from the AC when you’re working with it. This could be dangerous if they come into contact with the AC’s moving parts or electricity.

6. Read the owner’s manual for safety and maintenance tips before you begin tweaking your AC’s settings.

7. Make sure to unplug or turn off the unit when it is not in use; this will help reduce energy costs and wear and tear.

How to Prevent Dust and Grime Build-Up on Your Air Conditioner?

How to Prevent Dust and Grime Build Up on Your Air Conditioner

An air conditioner works by sending cooled air into your home. To do this, the unit circulates its internal parts that get warm during the cooling process. Unfortunately, dust and grime build up on these internal components over time, which causes additional wear on the system and leads to less than optimal performance. Hence, keeping these components clean is essential.

It is also essential to make sure that the unit’s exterior isn’t covered in dirt or debris, which would lessen its cooling ability as well. If you want to know more, check out this blog post on how to make an air conditioner colder. This would help give you some guidelines about your air conditioner.

How to Keep Your Air Conditioner in Good Working Order?

How to Keep Your Air Conditioner in Good Working Order

You can do a few things on your own to keep it in good order. Firstly, change the air filter according to the manufacturer’s instructions. Dirty filters make the unit work harder and less efficiently, leading to more wear and tear on components.

Checking the refrigerant level is also essential. A professional technician can do this, but if you are comfortable checking it yourself, you should do so annually. Sometimes refrigerant leaks go undiagnosed for months or even years before causing issues with the system.


As you can see, there are several ways to make your air conditioner colder. For example, one way is by turning the fan speed down and getting an insulation kit for your windows. Another option may be changing the filter on your furnace or installing a whole-home humidifier to help cool off the home more efficiently.

The point is that if you want cold air in summer heat then it’s possible with some creativity! We hope this blog post on how to make an air conditioner colder has been helpful.
