FAQs
What does your thorough electrical diagnostics service include?
Our technicians start with a full visual inspection of your service panel, outlets, fixtures, and any affected appliances. We then use calibrated multimeters, circuit tracers, and infrared cameras to measure voltage, current draw, resistance, and heat signatures. Every test point is documented so you receive a written report that lists code violations, failing components, and safety hazards along with recommended fixes—no guesswork, just data-driven conclusions.
How do I know if I need a diagnostic before an electrical repair?
If you are experiencing flickering lights, tripped breakers, burning odors, sparking outlets, or unexplained increases in your utility bill, a diagnostic is essential. Modern homes in Cosby often have hidden junction boxes and multiple circuits, so the root cause is rarely obvious. A proper diagnostic prevents incomplete or unnecessary repairs and ensures we correct the problem the first time.
How much does a diagnostic visit cost in Cosby and is it applied to the repair?
Our standard diagnostic fee is $99 for residences within a 20-mile radius of Cosby. For larger commercial sites the fee starts at $149 due to additional testing time. If you approve the quoted repair within 30 days, we credit 100 % of that diagnostic fee toward the final invoice, so you never pay twice for the same work.
Are your electricians licensed and insured to work in Cosby and the surrounding counties?
Yes. Every field technician carries a Tennessee State LLE (Limited Licensed Electrician) or Master Electrician license, plus $2 million in general liability and full workers’ compensation coverage. We also stay current with the latest NEC (National Electrical Code) and local Cosby amendments, so all repairs pass inspection and meet insurance requirements.
How soon can you complete repairs after diagnosing the problem?
In most residential cases we can start repairs the same day because our service vans are stocked with the most common breakers, receptacles, switches, and wire gauges. For specialty parts, we order immediately and schedule a return visit within 24–48 hours. Commercial projects may require permitting, but we handle the paperwork and coordinate with Cosby building officials to minimize downtime.
Do you guarantee your diagnostic findings and repair work?
Absolutely. We stand behind every diagnosis with a 90-day warranty—if the same issue reappears we’ll re-test at no charge. All repair parts and labor carry a minimum one-year warranty, and many components (such as breakers and panels) include manufacturer warranties of up to 10 years. You’ll receive all warranty details in writing before we leave the job site.
