When the mercury rises for multiple consecutive days, the temperature inside a home can quickly become unbearable. Now is the time to prepare for heatwaves!
A few easy adjustments are all it takes to keep your home cool and even reduce your energy consumption.
Inspect the Air Conditioner
It’s essential to make sure your air conditioning system is functioning properly before the first heatwave. Many homeowners wait until the first days over 30 °C to turn on their air conditioner for the season… only to discover that it’s not working when they really need it.
Clean or replace the filters (online how-to videos can help!), check the ducts if you have a central system, and make sure the outdoor unit isn’t blocked by leaves or debris. Preventative maintenance can improve the system’s efficiency and extend its lifespan.
If you plan on using portable or window air conditioners, it’s a good idea to purchase and install them before the onset of hot weather to avoid the crowds in shops or items being out of stock.
Keep the Heat Out
One of the most effective ways to keep a house cool is to stop the heat from entering in the first place. Sun-facing windows can rapidly turn certain rooms into veritable ovens.
- Close the curtains or blinds during the hottest part of the day, particularly on south- and west-facing windows.
- Thermal or blackout curtains can make a real difference during a heatwave.
- Other longer-term solutions: Install awnings, plant trees, and erect pergolas outdoors to provide shade and reduce heat build-up inside the house.
Check the Home’s Insulation
We typically worry about insulation in winter, but it also plays an important role in summer. A well-insulated house retains the cool air produced by the air conditioner more effectively.
A lot of warm outdoor air can get in through poorly sealed doors and windows. Check the weatherstripping and pinpoint any drafts. These small fixes improve not only comfort but also energy efficiency.
Prevent Indoor Overheating
We don’t realize how many household appliances give off heat. The oven, the television, the dryer, or even certain light fixtures can all contribute to raising the temperature inside the home.
- On very hot days, eat cold meals, cook on the barbecue, or use small kitchen appliances.
- Also try using the washing machine and dryer in the evening, when the temperature outside is lower.
Replace some light bulbs with LED models to help reduce the amount of heat the lights give off in rooms.
Remember the Importance of Air Quality
During heatwaves, the air inside homes can become stifling and humid. Poor ventilation often makes the heat even more oppressive.
Ceiling fans or portable fans can help improve air circulation. It’s also a good idea to air out your home early in the morning or late in the evening, when temperatures are cooler.
In some situations, a dehumidifier or an air purifier can also improve indoor comfort.
Protect the Most Vulnerable
One final point: very hot weather can be particularly hard on young children, the elderly, and pets. Houses that get too hot can quickly become dangerous. Ensure that you have a constant supply of cold water, create cool zones in your home, and keep an eye out for signs of heat exhaustion.
Happy summer!
