Your heater and air-conditioner are all that separate your home and business from the elements. For this reason, keeping them in top shape is imperative in Southern Ontario. Without heat and cooling, we are left to brave the elements on our own.
The Government of Ontario recommends the following to keep your costs of operation lower in the summer and winter months:

  • Heat and cool when the costs of electricity are lower, meaning nightly or on weekends.
  • Ensure your windows are leak proof to avoid unnecessary electricity use and install a programmable thermostat to have constant control over your energy use.
  • To ensure that your electricity costs are lower, you can install an Energy-Stars rated heating or cooling system.
