Most people do not care about how electrical systems in their home work; as long as the light goes on when they flip the switch they are satisfied. However, there may be potential for dangers in some of the electrical circuits that were installed in older buildings years ago. The increasing use of “high-drain” appliances, home office business machines, air conditioners, and other items that require an abundance of electricity was not foreseen by many home and commercial builders of decades ago.

Being an electrical contractor in Toronto has changed a great deal over the years.

The safe and efficient use of electricity in the home starts with a carefully planned electrical wiring system. Astron Electric Limited, your electrical contractor in Toronto, can help you plan the wiring for an upgrade to your electrical system, or wiring for a renovation to your house, or electric systems and fixtures for a new home or commercial building.

Keep in mind your present lifestyle and the future possibility of acquiring more appliances or such a luxury as a sauna, hot tub, or air conditioner. You should plan for a sufficient number of branch circuits for lights, appliances, and heating/cooling equipment to operate at full efficiency without excessive power drop.
