Stay Cool This Summer, Cost-Efficiently

Our team put together simple, low-cost tips to help keep you comfortable this summer season. Summertime in Nova Scotia is the best. But let’s face it, being too hot isn't pleasant. We put together a guide to help keep your home comfortable, without driving your energy costs up.
Keep your heat pump running optimally by cleaning its air filters. Once a month, remove them from the unit, rinse under hot water with no soap, and allow to dry before putting them back into the unit.
Whether you have a window unit or a heat-pump, you are using energy to generate cool air. If your space is comfortable without air conditioning, turn it off and save money.
If you don't have a heat-pump and are looking to purchase an air conditioner, consider an ENERGY STAR® model. ENERGY STAR® is the government-backed symbol for energy efficiency. Click here to visit the ENERGY STAR® website for a list of models
In the warmer months, your ceiling fan should rotate counterclockwise. This will push the cold air down and help keep your space cooler.
Fans don't actually cool a room – they move air, so their placement is important. Ensure your fan is placed next to an open window at night to allow it to pull in cool, outdoor air.
Block the sun from entering that space by closing the window curtains and blinds during the hours the sun is beaming in. It limits the sun’s heat from heating up your space.
Your oven is a large appliance that can throw a lot of heat – the last thing you need on a hot summer day. Instead, use a smaller appliance or your barbecue for dinner.
It'll cost you! We recommend keeping your air conditioner at 25°C, which should keep the room at a comfortable temperature.
