Tips to Make Your Air Conditioner Colder

Staying cool during hot weather is important, and your air conditioner plays a big part in that. An air conditioner works by taking the warm air from inside and cooling it down for you to enjoy.

Making sure your air conditioner gives out colder air can help keep you more comfortable. To do this well, you need to know about things like cleaning filters and where to put your thermostat.

Keeping an eye on the sun can also make a difference. If you use blinds or curtains, less sunlight gets in, which helps keep things cooler without making the air conditioner work too hard.

Sealing up gaps around your window unit stops warm outside air from coming in, so your room stays cooler with less effort.

Fans are good friends of air conditioners because they move cool air around faster so that it cools spaces quickly and saves power. Knowing where to place your thermostat matters too; keep it away from things that get hot so it can measure room temperature better.

Using these tips means thinking about how big your AC should be for the space and maybe even getting a new one if yours is old or not working well anymore because newer models usually cool better for less money spent on electricity.

Let’s find out how we can get our rooms really chilly this summer!

Understanding the Cooling Mechanism of Air Conditioners

Air conditioners work by moving warm indoor air over cold, refrigerant-filled coils. This process cools the air as heat transfers from the air to the refrigerant. The now cool air blows back into your home, lowering the temperature.

A key part is the compressor – it pumps the refrigerant between two sets of coils. One set releases heat outside (the condenser coil), and another absorbs it indoors (the evaporator coil).

The refrigerant changes from liquid to gas as it absorbs heat inside your house. It then travels outside where it gives up its heat and turns back into a liquid. This cycle repeats again and again until your home reaches the desired temperature that you’ve set on your thermostat.

Fans play an important role too; they circulate cool air throughout rooms via ducts or vents. All these parts need regular maintenance to keep them working effectively, which helps avoid common problems like obstructions in airflow that can reduce an AC’s cooling power.

Effective Ways to Enhance Your Air Conditioner’s Performance

To ensure your air conditioning operates at peak efficiency, implementing certain strategies can markedly improve its output. This section delves into practical methods to boost the performance of your cooling system without the need for technical expertise or costly investments.

Regular Cleaning and Replacement of Air Filters

Keep your air conditioner’s air filters clean to save on energy bills. Dirty filters make the system work harder, which uses more energy. Check and clean your filters every month, especially during heavy use periods like summer.

If they’re really dirty or damaged, it’s time for a new one.

Switch out old filters to keep the air fresh and allergen-free. New filters can trap dust and pollen better than old ones. This helps everyone breathe easier at home. Clean filters mean the cooling system doesn’t strain so you get cooler air without extra cost.

Ensuring Proper Sealing and Insulation

Check your home for air leaks around windows, doors, and air vents. Sealing these gaps keeps cool air in and hot air out. Use draught excluder or sealant to seal any openings you find.

Proper sealing boosts your HVAC system’s efficiency and helps it cool your space faster.

Insulate your loft and walls well. Good insulation acts like a cool bag, keeping the cold inside during summer months. Install insulation according to local building regulations to enhance energy efficiency.

Ensure the central air conditioner unit is the right size for your home; a unit too small or big affects performance and sealing.

Regularly maintain by cleaning or changing filters as part of ensuring that evaporator coils function optimally without straining from dust or dirt buildup in the system. Employing proper refrigerant types maintains good seals within the cooling mechanisms, preventing loss of cold air from the ACs throughout their operation cycle.

Optimal Thermostat Placement

Place your thermostat away from direct sunlight, drafts, and windows. This helps it measure the room temperature accurately. Make sure it’s on an interior wall in a room you use often.

Keep it at eye level for easy access and better performance.

Move to the next point: Use fans effectively. Fans can spread cool air throughout your home. Ceiling fans or pedestal fans work well with your air conditioning system for cooler comfort.

Utilising Fans for Improved Air Circulation

Fans play a key role in spreading cool air through your home. Position them to blow cooler air around, making each room feel more comfortable quickly. Ceiling fans should spin anticlockwise, pulling up warm air and pushing down the chilled breeze from your air conditioning unit.

This trick makes you feel cooler without turning the thermostat down.

Stand-alone fans also help move cold air from an air-conditioned space to other parts of the house. Try placing a fan near an open door or passageway. It helps share the coolness with nearby rooms that might not have direct airflow from your central air conditioners or HVAC systems.

Keep dust away from fan blades to ensure they work well and circulate fresh, clean air effectively.

The Importance of Cleaning Evaporator Coils for Cooler Air

Dirty evaporator coils can make your air conditioner work harder. This means it won’t cool the air as well. The coils take heat out of the air with refrigerant. When they are dirty, they can’t remove heat properly.

Then, your AC runs longer and uses more energy.

Cleaning these coils is a key step in keeping your system efficient. Use a gentle brush or cloth to remove dust and grime gently—never use harsh chemicals that could damage them.

For deeper cleans, consider hiring an expert who knows how to handle the coils without causing damage.

A clean condenser unit also helps keep everything running smoothly. Let’s look at how its maintenance affects performance next.

Recognising Common Issues Affecting Cooling Efficiency

Recognising common issues is crucial for maintaining your air conditioner’s efficiency. These problems can cause your AC to work harder and increase energy costs.

– Air filters clogged with dirt and debris restrict airflow, straining the cooling system. Clean or replace them regularly to keep your air conditioning systems running smoothly.

– Blocked or covered air vents prevent proper air circulation. Check that furniture or curtains are not obstructing vents to ensure efficient room cooling.

– A mismatch between unit size and home size affects performance. Ensure the air conditioner’s capacity matches the cooling load required for your space.

– Leaks in the air ducts lead to loss of cool air. Inspect ductwork for any gaps or holes and seal them properly to avoid wastage of cold air.

– Incorrect thermostat placement can misread actual temperatures leading to overuse of AC units. Place thermostats away from heat sources for accurate temperature control.

Stay alert for these common signs that hinder an AC’s efficiency as you move towards enhancing overall performance with regular maintenance.


Keep your air conditioner running cold and efficient. Clean or change the air filters regularly, and don’t forget about the evaporator coils. Make sure your home is well insulated and use fans to move cool air around.

Place your thermostat wisely to avoid false readings. Stay on top of maintenance for a comfy, chilled summer at home!


1. How can I use a garden hose to improve my air conditioner’s performance?

Attach the garden hose to an outdoor tap and gently rinse off your air conditioner’s outside unit. Remove dirt and debris to make your AC colder.

2. What should I do if my air conditioner isn’t cold enough?

Check the filters inside your home’s air handler unit. Clean or replace them regularly for better airflow and a cooler environment.

3. Why is it important to maintain my air conditioner regularly?

Regular maintenance keeps your AC running efficiently, so it blows colder air. It also saves money on energy bills and prevents big repairs.

4. Can I make my room cooler without calling a technician?

Certainly! Clear away any plants or objects blocking your outdoor AC unit with care, allowing for more effective cooling in your space.
