Why Upgrade Now

Is Your Generator Ready for Today's Electrical Load?

Most homeowners don’t realize their older generator can’t handle modern power demands. Generator system upgrades solve this problem. Your 10-year-old unit may struggle with new HVAC systems. It may not support electric vehicle chargers. Additional home office equipment adds even more load. We assess your current backup capacity. We compare it against actual household demand. Then we recommend specific upgrades that match your needs. Our electricians perform load calculations per NEC Article 220. This tells us if you need a larger unit. We determine if you need an upgraded automatic transfer switch. We also check if enhanced fuel delivery systems are required.

Technical Precision

Modern Transfer Switch Integration

We install 200-amp automatic transfer switches. These units prioritize critical circuits during an outage. Your refrigerator gets power first. Your heating system stays on. Your well pump keeps running. The switch manages the total load your generator can safely supply.

Common Questions

Residential Electrical FAQs

Common questions from Triangle homeowners about residential electrical services. Don’t see yours? Call us directly — we’re happy to help.
How do I know if my generator needs an upgrade?
Check the age of your generator first. Units over eight years old often need upgrades. Have you added major appliances like central air conditioning or an EV charger? Then you likely need more capacity. We perform a load calculation to compare your current power needs against your generator’s output. Warning signs include frequent overload shutdowns. Watch for slow engine cranking. A transfer switch that hesitates during power outages is another red flag.
Yes, we often upgrade transfer switches separately. This works when the generator itself still has good capacity. A modern automatic transfer switch with load management distributes available power better. It sends power to critical circuits first. We install switches rated from 100 to 400 amps depending on your panel size. This upgrade costs significantly less than replacing the entire generator unit.
Converting fuel types requires replacing the carburetor or fuel injectors. We adjust the regulator. A new gas line must run from your meter. We coordinate with licensed gas fitters for the supply line installation. Natural gas provides unlimited runtime during extended outages. Propane offers slightly better cold-weather starting. The conversion typically takes one full day. This includes testing and permit inspections.
Yes, any work involving the automatic transfer switch requires a permit. Changes to your main electrical panel also need permits in most jurisdictions. We pull all necessary permits before starting work. We schedule the required inspections. Unpermitted generator work can void your homeowner’s insurance. It creates liability issues. Our permit fees are included in our upgrade quotes. You won’t see any surprises.
That depends on your current unit and what you install. Upgrading from a typical 12kW generator to a 20kW unit nearly doubles your available power. You can run central air conditioning along with essential circuits. We measure your actual peak demand during our assessment. Most families upgrading from older 8-10kW units need at least 16-18kW. This covers modern electrical loads comfortably.

Most upgrades take one to two days depending on scope. Replacing just a transfer switch usually requires four to six hours. A complete generator replacement takes longer. This includes new gas lines, concrete pad work, and electrical connections. A full day is typical. We add a follow-up visit for final inspection. We schedule permit inspections in advance. This avoids delays in returning your backup power system to service.
