Eco-Friendly Tips to Keep Your Cooling & Heating System Running Smoothly

The way you use your cooling or heating system is just as important as the features. Here are some tips to help maximize their efficiency.

Monthly air conditioning and furnace cleanings will make your unit operate at maximum efficiency. Remember to change your filters twice a year!
In the summer set your thermostat to 25C, while in the colder months set it to 20C. This will help manage cooling and heating costs.
In the hotter months, make sure to turn off your air conditioner at night when the temperature dips. Similarly, lower your heater during the day in winter.
