Optimize ventilation for quality indoor air

Clean air inlets and outlets

Over time, dust, pollen and even insects can accumulate on air intake screens. This debris impairs ventilation efficiency, affects indoor air quality and can even shorten the life of your equipment. Remember to :

• Remove visible dust and debris from around external grilles.
• Check that dampers close properly and remain airtight.
• Clean exhaust vents, such as those in the dryer or bathroom.

Maintain your air exchanger

To ensure that your air exchanger operates to its full potential, we recommend that you :

• Switch off and unplug the unit.
• Remove filters and clean with hot, soapy water.
• Allow filters to dry completely before replacing.

Always consult the manufacturer's manual for instructions specific to your model.

Control indoor humidity

Close air exchanger if windows are open

In summer, if you don't have an air-conditioning system, natural ventilation through the windows is often sufficient. Leaving the air exchanger running continuously can bring in humid air unnecessarily.

Keep humidity below 55%.

Quebec's summer heat and humidity, combined with the moisture generated by daily life (up to 63 liters of water per week for a family of 4), can lead to :

• Condensation on windows
• Mould growth
• Bacterial growth

Use a hygrometer to measure relative humidity. If it exceeds 55%, it's time to take action.

Use a dehumidifier if necessary

Choose an ENERGY STAR-certified model, which is more energy-efficient and quieter. Consider extraction capacity and sound level according to your needs.

Clean range hood filters

Grease filters quickly accumulate residues. Regular cleaning will maintain your hood's performance and prevent lingering odors in your home.

Simple, effective cleaning:

• Fill sink with boiling water.
• Add 1/4 cup baking soda and a little dish soap.
• Sprinkle filters with baking soda too.
• Soak for one hour.
• Brush, rinse and dry thoroughly before replacing.

Maintain the surroundings of your home

Clear the vegetation around the house to a perimeter of 24 inches (60 cm).

This prevents problems related to :

• Insects and small rodents attracted by plants or food residues.
• Excessive humidity near foundations, caused by watering too close to the foundation.
• Root growth that can damage infrastructure.
• Minimal clearance around the house is an excellent preventive measure against infiltration, pests and premature wear of exterior cladding.
