FAQs
Why is preventive maintenance important for my electrical system in Cowan?
Cowanâs humid summers and cool winters put extra stress on wiring, breakers, and outdoor service equipment. Preventive maintenance finds loose connections, insulation breakdown, corrosion, and overloaded circuits before they cause outages, fires, or expensive downtime. By scheduling routine inspections you stay compliant with local safety codes, protect valuable appliances, and extend the life of your entire electrical system.
How often should I schedule electrical preventive maintenance for my home or business?
For most residences we recommend a full electrical safety check every two years and a breaker-panel torque test once a year. Commercial and industrial facilities with higher loads or critical equipment should plan semi-annual visits. If your property is older than 25 years, has undergone recent renovations, or supports sensitive electronics, annual maintenance is the safest interval.
What does your preventive electrical maintenance service include?
Our licensed electricians perform a 25-point inspection that covers: infrared thermography of panels to detect hot spots; tightening of lugs, neutrals, and grounds; testing of GFCI/AFCI devices; load balancing; breaker trip calibration; megger testing of motor and feeder insulation; cleaning of switchgear and transformer vents; verification of surge protection; and a written report with prioritized repair recommendations.
Can preventive maintenance help lower my energy bills?
Yes. Loose terminations, unbalanced phases, and aging motors waste energy as heat. During maintenance we correct these inefficiencies, recommend LED lighting or high-efficiency transformer upgrades, and make sure power factor stays within utility thresholds. Customers typically see 5â15 % reductions in monthly electric costs once issues are corrected.
Are your electricians licensed and familiar with Cowan electrical codes?
Absolutely. Every technician holds a Tennessee Journeyman or Master Electrician license, carries full liability and workersâ compensation insurance, and receives ongoing training in the latest National Electrical Code (NEC) revisions. We also coordinate with the Franklin County Building & Codes Department to ensure all repairs and upgrades meet local permitting requirements.
What signs indicate I need immediate electrical repair instead of waiting for the next maintenance visit?
Call us right away if you notice frequent breaker trips, burning smells from outlets, flickering lights on a single circuit, warm or buzzing panels, sparking receptacles, or water intrusion near electrical equipment. These symptoms signal imminent hazards that require urgent troubleshooting and repairâwaiting could lead to fire or equipment failure.
