Electrical Warning Signs in Older Lubbock Homes
Short answer: in an older home, the signs worth a call to a licensed electrician are lights that flicker or dim, switch plates or outlets that feel warm, buzzing or crackling, a burning smell, breakers or fuses that trip often, a fuse box, two-prong outlets, and silver-colored aluminum branch wiring. None of these proves a problem on its own. Together, or in a house from the 1950s to 1970s, they are a good reason to get an evaluation.
If you see smoke or fire, or smell burning that won't go away, get out and call 911.
How old is Lubbock's housing?
Lubbock, TX has a large stock of mid-century homes. In the Census Bureau's American Community Survey (ACS 2020–24 5-year), 44.7% of homes in the city were built before 1980, and about 33,200 homes, roughly 28%, date from the 1960s and 1970s. Near Texas Tech the numbers climb: in ZIP code 79410, around Tech Terrace and Overton, the median home was built in 1957, and in 79413, around Rush, the median is 1963.
Older doesn't mean unsafe. Many of these homes have been updated. But wiring, panels and outlets from those decades were designed for far less load than a modern household puts on them, especially with central air running hard. Lubbock averages about 92 days a year at 90°F or hotter (NOAA 1991–2020).
Warning signs and what they may mean
| Sign | What it may point to | How soon to act |
|---|---|---|
| Burning smell, smoke, scorch marks | Overheating connection or device | Now: shut off the circuit if safe; 911 if smoke or fire |
| Warm switch plate or outlet | Loose connection, overloaded circuit, worn device | Soon: stop using it and call an electrician |
| Buzzing or crackling | Arcing at a device or in the panel | Soon |
| Lights flicker or dim when the AC starts | Heavy load on the circuit or service; loose connection | Get it checked, especially if it is getting worse |
| Breakers trip or fuses blow often | Overloaded circuit, failing breaker, short | Get it checked; don't upsize a fuse or breaker |
| Fuse box | Original or very old service | Plan an evaluation |
| Two-prong outlets | Ungrounded circuits | Plan an update |
| Silver-colored branch wiring | Possible aluminum wiring (CPSC era 1965 to mid-1970s) | Plan an evaluation |
Flickering lights and warm switch plates
One flickering bulb is usually the bulb. Flicker across several rooms, or dimming every time the air conditioner kicks on, can point to a heavy load or a loose connection somewhere between the meter and the fixture. A switch plate or outlet that feels warm to the touch is a sign of heat at a connection. Stop using it and have it looked at. Dimmers can run slightly warm by design, which an electrician can sort out quickly.
Buzzing, crackling and a burning smell
Outlets, switches and panels should be quiet. Buzzing or crackling can mean arcing, which creates heat. A burning or hot-plastic smell with no obvious source is the most urgent sign on this list. If you can do so safely, turn off the breaker for that area, and call an electrician. Our emergency electrician page explains what to do first.
A fuse box or an older panel
Fuse boxes aren't automatically dangerous, but they are often a sign of original, smaller service, and they invite the risky habit of putting in a bigger fuse when one keeps blowing. Some insurers also ask about older panel brands. The CPSC closed its 1983 investigation of Federal Pacific Stab-Lok breakers without finding that its data established a serious risk, but it said its data were limited, and some insurers treat those panels as a concern. Some insurers ask about Zinsco panels too; ask your agent. Our post on Federal Pacific and Zinsco panels goes deeper, and the panel upgrade and replacement page explains the work.
Two-prong outlets
Two-prong outlets mean the circuit likely has no ground wire. That matters for three-prong appliances, electronics and surge protectors. There are code-recognized ways to update them, including GFCI protection. See two-prong outlets: can you swap them?
Aluminum wiring
The U.S. Consumer Product Safety Commission says homes built before 1965 are unlikely to have aluminum branch wiring, while wiring installed between 1965 and the mid-1970s may contain it. CPSC reports that pre-1972 homes wired with aluminum are "55 times more likely" to have connections reach "Fire Hazard Conditions" than homes wired with copper. CPSC recognizes three repairs: rewiring with copper, COPALUM crimp connectors and AlumiConn connectors. Read aluminum wiring in Lubbock homes or the rewiring and aluminum wiring page.
Don't open the panel to look. Checking wiring type, panel brand or connections inside the panel is a job for a licensed electrician. The panel label, the age of the house and what you can see at the outlets are enough to describe the situation in a quote request.

Before you hire
Texas requires electrical contractors and electricians to be licensed by TDLR (Occupations Code Ch. 1305). Check any license at tdlr.texas.gov/LicenseSearch and look for the TECL number on the truck and the written proposal. Ask for a certificate of insurance, ask about any trip or diagnostic fee, and ask who pulls the permit for repairs.

Frequently asked questions
What are the signs of old wiring in a house?
Common signs include flickering or dimming lights, warm switch plates or outlets, buzzing, a burning smell, frequent tripping, a fuse box, two-prong outlets and cloth-covered or silver-colored wiring. A licensed electrician can confirm what is there.
Are lights that dim when the AC starts a problem?
A brief dip can be normal when a large motor starts. Dimming that is getting worse, flicker across several rooms or lights that stay dim are worth having an electrician check, since they can point to a heavy load or a loose connection.
Does a 1960s Lubbock home need rewiring?
Not automatically. Many have been updated. Homes wired between 1965 and the mid-1970s may contain aluminum branch wiring, according to the CPSC. An evaluation tells you what is in the walls and which repairs, if any, make sense.
How much does an electrical inspection cost?
National cost guides put an electrical inspection at about $149–$312 (homeyou). These are estimates, not quotes. Ask for the price and what is included in writing before the visit.
