How to Make Your Air Conditioner Colder: Top Tips & Tricks

Are you struggling to keep your home cool with an inefficient air conditioner? Many homeowners experience this problem during the hot summer months. But many simple things can be done to make your air conditioner colder and more efficient.

In this blog, we’ll provide some top tips and tricks on maximising cooling efficiency and ensuring a comfortable home environment. So, let’s get started – read on for our top tips!

How To Make Your Air Conditioner Colder

Keep your air conditioning system running efficiently and cool the room more effectively with these easy steps – read on to find out more!

Change The Air Filter

Changing the air filter is essential for ensuring your AC works efficiently. The air filter traps dirt and other particulates, and when it becomes clogged, it blocks airflow to your AC unit.

This can lead to reduced cooling, higher energy bills and damage to the compressor over time. CIt’shanging the air filter every 3-6 months or more often in environments with high dust concentrations, pet hair, or smoke particles is important.

Check The Refrigerant Levels

The refrigerant is the component that helps to cool the air in your AC unit, and when the levels are low, it makes it difficult for the air conditioner to work effectively. This may result in warm or lukewarm air coming out of your vents instead of cool air. To ensure this isn’t happening, check the levels at least once a year and, if needed, have a professional refill them.

Additionally, looking out for any signs of refrigerant leaks would be best. Suppose there is an issue with the leaking refrigerant. In that case, you should call a professional as soon as possible so they can assess and repair any damages caused by the leak before refilling it again. Doing so will help keep your AC working efficiently all summer long!

Adjust The Thermostat

Adjusting the thermostat inside your house can help make your air conditioner colder. To keep you comfortable, adjust it to a lower temperature than usual.

This way, your AC unit will have to work harder and run longer to cool down the room, resulting in cooler air coming out of the vents. It’s also recommended that you buy a programmable thermostat if possible so you can easily set different temperatures throughout the day or night to get optimal cooling according to your preferences.

Check The Air Flow

Checking and clearing any blockages or obstructions in the airflow is important to improving your unit’s cooling efficiency. Blockages can prevent cooler, conditioned air from reaching your home and reduce the system’s overall performance.

To check that the airflow is not blocked, inspect all ducts, vents, filters and coils for signs of dirt or debris build-up and clear any clogs found. Additionally, make sure that all fan blades are clean and free-spinning, as a malfunctioning fan will not be able to supply enough necessary cool airflow.

Finally, it’s also important to check for any cracks or breaks in ductwork, as these can reduce cooled airflow into each room in your house, resulting in poor cooling efficiency.

Seal Any Air Leaks

Sealing air leaks around the home is an effective way to ensure your air conditioner runs more efficiently. A simple caulk or expanding foam sealant on all windows, door frames, electrical outlets, and pipes can help prevent outside air from entering your home, cooling it faster.

Furthermore, checking for any ductwork leakage can also increase the efficiency of your AC system. Applying mastic or metal foil tape to joints in exposed ducts and ensuring no loose connections can improve cold air distribution and save you money on energy bills.

Keep The Vents Open

Keeping the vents open ensures your air conditioner is constantly supplied with fresh air. This keeps it running at an optimal level and helps to reduce strain on its components.

Closing the vents might cause a build-up of dust and debris, which can significantly reduce its efficiency and increase energy costs.

Use A Programmable Thermostat

A programmable thermostat is an ideal way to make your air conditioner colder and save money on energy bills. It helps you adjust the temperature according to certain programs compatible with your lifestyle so that it can turn itself up or down at predefined times of the day.

It also allows you to set different temperatures when you’re home, asleep, at work, or on vacation. This ensures a super-efficient cooling system by using only as much energy as necessary while providing maximum comfort levels in your living environment.

Programmable thermostats are easy to install and use – all you need is a few minutes of instruction and some basic tools for installation, after which their user-friendly interface will get you quickly accustomed and comfortable with programming schedules.

Clean The Condenser Coils

Condenser coils play a crucial role in the functioning of an air conditioner. They should be routinely cleaned to ensure cooling efficiency and reduce energy consumption. Dirt can accumulate and block air flow through these coils, making them unable to do their job properly.

Cleaning condenser coils regularly using either a brush or compressed air is important. This will help keep your system running efficiently, improving its ability to cool down your home without overworking itself, which could lead to damage. Additionally, when condenser coils are dirty, they require more power consumption leading to higher electricity bills, so cleaning them can result in significant savings.

Install An Air Purifier

Installing an air purifier in your home can help your air conditioner work more efficiently and cool down faster. An air purifier helps to remove dust, dirt and other airborne particles, which can reduce the efficiency of cooling units. Also, it traps pollutants that could otherwise build up inside the AC unit, leading to higher energy consumption and additional maintenance costs.

Moreover, by removing impurities from the air inside a room or house, an air purifier will improve indoor air quality while helping to keep rooms colder for longer periods. Not only this, but an advanced model may even offer some humidity control functions, allowing you to create a pleasant and comfortable environment at home during the summer months without having to overuse your HVAC system.


In conclusion, ensuring your air conditioner runs efficiently can bring many benefits. From lower energy bills to enhanced comfort levels, you and your family can enjoy a cool home without worrying about any added costs or damage.

By following the simple steps listed above, you can ensure that your air conditioner continues to provide an even chill for years to come.
