How to Keep Your Home Cool During an Irish Summer

Irish summer weather can change quickly, but when the warm days arrive, homes can heat up faster than many people expect. Bedrooms, home offices, apartments, conservatories and south-facing rooms can become uncomfortable, especially during still, humid spells.

Met Éireann’s forecast for Saturday 13 June 2026 pointed to highs of 17 to 22°C in Leinster and Munster, with further warm weather expected on Sunday. Its seasonal outlook for July, August and September also signals above-average temperatures overall, making now a good time to think about practical cooling at home.

The good news is that you do not always need a full air conditioning setup to feel more comfortable. Depending on your space, budget and routine, a fan, portable air conditioner, air cooler, dehumidifier or air purifier can all play a useful role. At Euronics Ireland, you can browse cooling appliances including fans, air conditioners, air coolers and dehumidifiers for different rooms and household needs.

Start with simple cooling habits

Before choosing an appliance, it helps to control the heat entering your home. HSE hot weather guidance recommends closing curtains in rooms that get morning or afternoon sun, closing windows that face the sun during the day, and opening windows at night when temperatures drop, where it is safe to do so.

You can also reduce indoor heat by turning off lights and appliances you are not using. Ovens, dryers, chargers, computers and lighting can all add warmth to a room, so small changes can make a noticeable difference during hot spells.

Close blinds or curtains on sunny windows during the hottest part of the day.
Open windows in the evening or at night if the air outside is cooler.
Turn off unnecessary appliances and lights.
Use lighter bedding in warm bedrooms.
Avoid cooking with the oven during the hottest hours if possible.

Fans: the simple choice for everyday comfort

A fan is often the easiest and most affordable way to improve comfort in warm weather. Fans do not lower the room temperature in the same way an air conditioner does, but they move air across your skin, helping you feel cooler.

They are a good option for bedrooms, living rooms, desks, kitchens and home offices, especially when temperatures are warm but not extreme. HSE guidance says electric fans can be used in hot weather, though caution is advised at very high temperatures.

When choosing a fan, think about room size and how you will use it. A desk fan is ideal for personal cooling while working. A pedestal fan can cover a larger area. A tower or bladeless fan may suit living spaces where you want a slimmer design.

Portable air conditioners: best when you need stronger cooling

A portable air conditioner is designed to actively cool the air, making it a stronger option for rooms that become genuinely uncomfortable. This can be useful for bedrooms during warm nights, attic rooms, apartments, home offices or rooms with large windows.

Portable air conditioners usually need to vent warm air outside through a window kit or hose, so placement matters. Before buying, check the room size, the available window position and whether you can safely fit the venting setup.

Key features to compare include cooling capacity, noise level, timer settings, fan speeds, remote control, sleep mode and whether the unit also has a dehumidifying function. If the room is used for sleeping, pay particular attention to noise and night-time settings.

Air coolers: useful for personal cooling

Air coolers sit somewhere between a fan and an air conditioner. They use water or ice packs to help cool the airflow, but they do not refrigerate the air like a true air conditioner.

An air cooler may suit someone who wants more comfort than a basic fan but does not need the stronger cooling of an air conditioner. They are often best for personal cooling in a smaller space rather than whole-room temperature control.

Because air coolers add moisture to the air, they may not be ideal in already humid rooms. If your home tends to feel damp or stuffy, a dehumidifier may be the better supporting appliance.

Dehumidifiers: not just for winter

Many people think of dehumidifiers as winter appliances, but they can also help in warm, humid weather. High humidity can make a room feel heavier and less comfortable, even if the temperature is not especially high.

A dehumidifier removes moisture from the air, which can help rooms feel fresher and may also support better drying of laundry indoors. This can be especially useful in apartments, utility rooms, bedrooms, bathrooms and older homes where ventilation is limited.

A dehumidifier will not cool a room like an air conditioner, but reducing humidity can improve comfort and help manage condensation, musty smells and dampness.

Air purifiers: useful when windows are closed

During warm spells, many households close curtains and windows during the day to keep heat out. That can help with temperature, but it may also make rooms feel stale, especially in homes with pets, dust, pollen or cooking smells.

An air purifier does not cool the room, but it can help improve air freshness by filtering particles from the air. This may be useful for bedrooms, home offices and living spaces where comfort depends on both temperature and air quality.

Which cooling appliance is right for your room?

The right choice depends on what problem you are trying to solve.

For quick personal cooling: choose a desk fan, tower fan or pedestal fan.
For a hot bedroom or office: consider a portable air conditioner.
For a smaller space where you want cooler airflow: consider an air cooler.
For damp or humid rooms: choose a dehumidifier.
For stuffy rooms where windows stay closed: consider an air purifier.

What to check before buying

Before choosing a cooling appliance, consider the room, the people using it and how often it will run.

Room size: larger rooms need more powerful airflow or cooling capacity.
Noise level: important for bedrooms, nurseries and home offices.
Running time: timers and sleep modes can help manage overnight use.
Portability: wheels, handles and weight matter if you will move it between rooms.
Ventilation: portable air conditioners need a suitable way to vent warm air outside.
Humidity: humid homes may benefit from dehumidifying features.
Controls: remote controls, digital displays and app features can make daily use easier.

Keep safety in mind during hot weather

Cooling appliances can make warm days more comfortable, but they should be part of a wider approach to staying safe. HSE advice highlights the importance of hydration, staying out of the strongest heat where possible, using shade, and keeping indoor spaces cool.

People over 65, babies and young children, and people with underlying health conditions can be more vulnerable during heatwaves. If you are buying a cooling appliance for someone at higher risk, prioritise easy controls, reliable cooling, low noise and safe placement.

The bottom line

For many Irish homes, a good fan is enough for everyday summer comfort. For hotter bedrooms, apartments or home offices, a portable air conditioner may be worth considering. If humidity is the issue, a dehumidifier can make a room feel fresher and more comfortable, while an air purifier can help when windows are closed for long periods.
