FAQs about electrical wiring in London, ON

There are many ways to tell if your home’s electrical wiring is poor. Some of the most common signs of bad wiring include frequently tripped circuit breakers, flickering or dimming lights, buzzing or crackling sounds, frayed wires, smoke emanating from outlets or appliances, burning smells or scorch marks on electrical fixtures, and warm or vibrating spots on outlets or walls.

If you’re concerned about the existing electrical wiring in your home, the best thing you can do is hire a professional electrician to assess the electrical system. M&K Heating and Air Conditioning technicians are all fully licensed and certified and will be able to offer a professional opinion as to the condition of your home’s electrical wiring. Contact us as soon as you suspect an issue, as failing to repair faulty wiring can lead to sparking, overheating, and fire.

Generally speaking, electrical wiring should last 50 years or more. However, it depends on the type of metal wire used, if it has any protective coating and if so, the type of coating, and how well the wiring was installed. For example, aluminum wiring is not as durable as copper. Where copper wiring may last 100 years without needing to be replaced, aluminum wiring may last closer to 80 years. Beyond the type of metal used, the protective coating on the wiring (which ranges from knob and tube wiring to cloth wiring) can also impact its lifespan. Finally, if the wiring was badly installed to begin with or amateur modifications were made to it along the way, the lifespan of your home’s electrical wiring may be reduced. Ultimately, whether you’ve started to notice some of the telltale signs of bad wiring or not, we recommend hiring a licensed electrician to inspect your electrical system every 25 years.

What Homeowners Say About Us

“I recently had an Air Conditioner and Furnace installed by M&K. I called around and talked with several companies, they have the best warranty and were the most knowledgeable when it came to answering my questions. Everything was installed perfectly and up to code in a timely manner. Very happy with the system and service!“​
