From electrical repairs and installations to wiring and home renovation projects, we will ensure your home’s electrical system is in tip-top shape. 


This is a difficult question to answer as the cost of fixing an electrical problem varies widely depending on a number of factors. For example, the size of your property, the severity of the problem, and the technician’s diagnosis can all influence how much a residential electrical repair costs. For this reason, we recommend contacting a trusted electrical professional as soon as you suspect there may be an issue. One of M&K Heating and Air Conditioning’s expert electricians will be happy to assess the situation and offer an accurate and competitive quote for any necessary repairs.

The answer to this question depends on the type of electrical system in your London, Ontario home. If your electrical system is aluminum, we recommend having a reputable electrician inspect it every 25 years. In contrast, if your home has a copper electrical system, regular inspections can be less frequent as copper is known for its durability.

That said, if you recently bought a new home or live in an old home, you may wish to have your electrical system inspected more regularly.

Electrical work is one project you should never DIY. This is because, without the proper knowledge or training, you can easily overload a circuit, possibly leading to injury or property damage. More specifically, the risks of trying to do electrical work yourself include electrocution (which can be fatal), electrical shock (not fatal but can lead to seizures and heart attacks), and serious property damage caused by sparks or fires.

For these reasons, London homeowners should never attempt to do their own electrical work. Instead, hire a licensed electrician who knows what they’re doing and will find a solution to your electrical problem in no time.

As our homes use electricity every single day, homeowners will generally be able to tell when they need to call an electrician to their home. With that said, not all signs are as common as others, which can lead to unanticipated risks. Therefore, to determine whether you need an electrician to come to your home, take a look at some of these signs below:

  • You are using too many extension cords in your home
  • You notice that your fuse box wires are singed
  • Your electrical outlets feel warm to the touch
  • Your circuit breakers regularly trip
  • There are flickering lights throughout your home
  • There is a potent burning smell throughout your home
  • You hear a buzzing noise throughout your home.
  • You frequently experience an electric shock when you plug in your appliances

Do any of these signs look familiar? If the answer is yes, book an appointment with one of the certified electricians at M&K Heating and Air Conditioning today!

There are numerous benefits to hiring a professional electrician to perform electrical work throughout your home. These benefits include:

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!“​
