If your Colorado home was built or renovated in the 1960s or 1970s, there’s a chance aluminum wiring may be part of its electrical system. Aluminum wiring isn’t automatically a reason to panic, but it does deserve attention—especially as electrical systems age and today’s homes place greater demand on them.
At Colorado Integrated Electrical Systems (CIES), thermal imaging is one of the tools we can use during an electrical evaluation to look beyond what’s visible and identify areas that may warrant a closer inspection.
Why Is Aluminum Wiring a Concern?
Aluminum wiring was commonly used in residential construction during the 1960s and 1970s as an alternative to copper. The concern isn’t simply that the wiring is aluminum. Problems can develop at connections, terminals, switches, outlets, and other devices if the installation or components aren’t appropriate for aluminum conductors.
Over time, expansion and contraction, oxidation, or loose connections can contribute to increased electrical resistance. Increased resistance can generate heat—and excessive heat at an electrical connection is something you don’t want to ignore.
Because these issues can occur behind outlets, inside panels, or at other connection points, homeowners may not always see an obvious warning sign.
What Is Thermal Imaging?
Thermal imaging uses an infrared camera to detect differences in surface temperature. For electricians, it can provide another layer of information when evaluating an electrical system.
Rather than opening every wall or relying only on what can be seen with the naked eye, a thermal camera can help identify unusual heat patterns at accessible electrical components.
For example, an electrician may notice a breaker, connection, outlet, or other component operating at a noticeably different temperature than surrounding components. That temperature difference doesn’t automatically tell us what the problem is—but it tells us where further investigation may be needed.
How Can Thermal Imaging Help With Aluminum Wiring?
Thermal imaging cannot look through a wall and tell you, “There’s aluminum wiring here,” nor can it replace a hands-on electrical inspection.
What it can do is help identify abnormal heat associated with electrical resistance or connection issues.
In a home with known or suspected aluminum wiring, that information can be particularly useful. If thermal imaging identifies an unusually warm area, a licensed electrician can investigate further to determine the cause and recommend the appropriate next step.
Think of thermal imaging as another set of eyes—ones that can see temperature differences we can’t see ourselves.
Warning Signs Homeowners Should Pay Attention To
Whether your home has aluminum or copper wiring, certain electrical symptoms deserve professional attention. These can include:
- Warm or discolored outlets and switch plates
- Flickering lights
- Frequently tripped breakers
- A burning or unusual electrical smell
- Crackling or buzzing near switches or outlets
- Outlets or switches that stop working intermittently
- Evidence of previous electrical repairs or modifications you’re unsure about
If you notice any of these signs, don’t wait for a thermal imaging inspection to address them. Have the electrical system evaluated by a qualified electrician.
Does Aluminum Wiring Mean You Need to Rewire Your Entire House?
Not necessarily.
Finding aluminum wiring doesn’t automatically mean a whole-home rewire is the only solution. The appropriate recommendation depends on the type and condition of the wiring, how it was installed, the devices and connections being used, and what an electrician finds during an inspection.
That’s why proper evaluation matters.
At CIES, our goal isn’t to recommend work you don’t need. It’s to understand what’s happening within your electrical system, identify areas of concern, and explain your options so you can make an informed decision.
Thermal Imaging Gives Us More Information Without Guesswork
Electrical problems aren’t always obvious. A breaker may look normal from the outside while operating hotter than expected. A connection may appear fine until it’s evaluated more closely.
Thermal imaging gives our electricians another diagnostic tool to help identify those areas before determining whether additional investigation or repair is necessary.
For owners of older Colorado homes—particularly those with known or suspected aluminum wiring—it can be a valuable part of a broader electrical evaluation.
Not Sure What’s Behind Your Walls? Start With an Electrical Evaluation.
If you’ve purchased an older home, have been told you have aluminum wiring, or simply aren’t sure about the condition of your electrical system, CIES can help.
Our licensed electricians can evaluate your system, identify potential concerns, and use tools such as thermal imaging when appropriate to get a better picture of how your electrical components are performing.
