A standard three-prong electrical outlet typically lasts for about 15 years with normal use and should be replaced accordingly. GFCI outlets may have a longer lifespan of 15 to 25 years. While some outlets can last longer if used infrequently, they can also fail prematurely. Reasons for early failure include poor wiring, an overloaded circuit, improper grounding or installation, or loose plugs. Signs that an outlet is failing include flickering lights, overheating, a discolored or melted faceplate, plugs that fall out easily, or frequently tripping circuit breakers. It is essential to address faulty outlets promptly to avoid safety hazards, especially in homes older than 15 years.

It can be safe to buy or live in a house with knob and tube (K&T) wiring, but only if the system is in good condition, functional, and has been thoroughly inspected and approved by a licensed electrician. Never purchase a home with K&T wiring without getting a professional electrical inspection first.

Key considerations include:

• Safety and Condition: An inspector will verify that the wiring is safe and has not deteriorated. Over time, the insulation can wear away, leaving exposed wires that pose a significant fire or shock hazard.

• System Capacity: The electrical service should be at least 60 amps. However, even at this capacity, K&T systems often struggle to handle the demands of modern appliances and electronics.

• Lack of Grounding: Knob and tube wiring is an ungrounded system, which is a safety concern for many modern devices.

• Ongoing Maintenance: If you live in a home with K&T wiring, it's recommended to have it inspected by an electrician every one to two years to ensure it remains in safe working order.

Ultimately, any inspection or modification of a knob and tube system should always be performed by a certified professional.

If your thermostat does not have a C-wire, you can hire a professional to check for an abandoned C-wire hidden in the wall, install a new C-wire, repurpose an existing G-wire to function as a C-wire, or purchase a C-wire adapter kit. 

There are some smart thermostat models that do not require a C-wire, but this will limit the functionality of the smart technology.

The safest option is to let a technician conduct the inspection. However, if you are certain that the capacitor failed and you take all precautions to avoid electric shock, you can take a look yourself. Usually, you can open the front panel of the unit and use a flashlight to find the small capacitor cylinder. It should have a sticker on it that provides its product number, capacity, and similar information that you can note when talking to a contractor.
