5 Signs Your Home Needs an Electrical Thermal Inspection

Most homeowners do not think about their electrical system until something goes wrong -- a breaker trips, an outlet stops working, or worse, they smell something burning. But electrical problems rarely appear without warning. The signs are there. They are just easy to overlook or dismiss.

An electrical thermal inspection uses thermal imaging to see what your eyes cannot: heat building up inside your walls, behind your panels, and at connections that are slowly failing. Here are five signs that your home could benefit from an infrared electrical inspection.

1. Your Electrical Panel Is More Than 25 Years Old

Electrical panels do not last forever. Breakers degrade over time, connections loosen as metals expand and contract through thousands of heating and cooling cycles, and older panel designs may not meet current safety standards.

If your home's electrical panel was installed more than 25 years ago, there is a meaningful chance that internal components are generating excess heat -- even if everything appears to work normally from the outside. Certain panel brands from the 1970s through 1990s, including Federal Pacific and Zinsco, are known to have significantly higher failure rates.

An electrical thermography scan can evaluate the thermal condition of every breaker and connection in your panel in minutes, without shutting off your power.

2. Breakers Trip Frequently or Randomly

Occasional breaker trips are normal, especially if you overload a circuit with too many appliances. But if breakers trip frequently, trip without an obvious cause, or if the same breaker trips repeatedly, something deeper is going on.

Common causes include:

• Internal breaker degradation -- the breaker's trip mechanism has weakened and is no longer calibrated correctly
• Loose connections at the breaker or bus bar generating heat under load
• Overloaded circuits that are consistently carrying more current than they are rated for
• Wiring issues inside walls that cause intermittent faults

Thermal imaging can pinpoint which components are overheating, giving your electrician a precise target for repairs instead of guesswork.

3. You Notice Warm or Discolored Outlets and Switches

If an outlet or light switch feels warm to the touch, or if you see discoloration (yellowing or browning) on the cover plate, that is a sign of heat buildup behind the wall. This is not something to ignore or monitor casually -- it indicates an active problem that is generating enough heat to affect surface temperatures.

Potential causes include loose wire connections, undersized wiring, backstabbed connections (a common shortcut in residential wiring), or a failing device. An infrared electrical inspection can map the heat pattern behind the wall and identify exactly where the problem is, without cutting into drywall.

4. You Have Had Additions, Renovations, or Increased Electrical Load

South Florida homes frequently undergo renovations, room additions, garage conversions, and upgrades like EV charger installations, pool equipment, or home offices with heavy equipment. Each of these changes adds load to your electrical system.

The question is whether your existing panel and wiring can handle it. Just because a new circuit was added does not mean the panel it was connected to is in good condition, or that the overall load is properly balanced.

After any significant change to your home's electrical load, a thermal imaging inspection is a smart way to verify that everything is operating within safe temperature ranges. This is especially important if the work was done by a previous owner and you do not have documentation of what was changed.

5. Your Home Insurance Requires or Recommends It

Insurance carriers in South Florida are paying closer attention to electrical risk. Some carriers now require an electrical inspection -- including thermal scanning -- as a condition of issuing or renewing a homeowner's policy, particularly for older homes.

Even if your insurer has not specifically required an electrical thermography inspection, having one on file can work in your favor. It demonstrates proactive maintenance, may qualify you for premium discounts, and provides documented evidence of your system's condition in the event of a claim.

Additionally, if your home is part of a condominium or multi-family building approaching its 40-year recertification in Miami-Dade or Broward County, the building's electrical systems will need to be evaluated. Individual unit panels are often included in this process, and a thermal scan provides the most thorough assessment.

What to Expect from a Residential Thermal Inspection

A residential infrared electrical inspection is straightforward and non-disruptive. Here is what the process typically looks like:

1. Preparation -- For best results, your home should be under normal electrical load. Run your air conditioning, appliances, and other typical loads before the inspection.
2. Scanning -- A certified Level II thermographer scans your electrical panel, sub-panels, outlets, switches, and any areas of concern using a calibrated thermal camera.
3. Analysis -- Thermal images are reviewed for hot spots and abnormal temperature patterns, assessed against NFPA 70B severity guidelines.
4. Reporting -- You receive a clear report with thermal images, findings, and recommended actions.

The entire process takes about an hour for most homes and does not require turning off your power.

Protect Your Home and Family

Electrical fires are preventable. The warning signs are there -- you just need the right technology to see them. If any of the signs above apply to your home, an electrical thermal inspection is a small investment that can prevent a catastrophic outcome.
