ELECTRICAL CALCULATORS
See what you're actually spending — and what a licensed electrician could save you. Real numbers, not guesses.
Calculator 01
EV Home Charging Savings
Compare what you pay at public charging stations versus what you'd pay charging at home. Most EV owners save over $1,000/year with a Level 2 home charger.
Your Vehicle
Charging Details
Houston area avg: $0.155/kWh
Why this matters: At Houston rates, home charging costs 64% less per kWh than a Tesla Supercharger. Over 5 years, the gap compounds significantly.

LED Lighting Savings
LEDs use 85% less energy than incandescent bulbs and last 25x longer. See exactly what switching your home to LED would save you — energy costs and bulb replacement combined.
Your Lighting
Did you know? LEDs use 85% less energy than incandescent bulbs and last 25× longer. A single incandescent burning 5 hrs/day needs replacing every 6 months. An LED lasts 13+ years.
Beyond the bulb: Aging incandescent wiring and fixtures often have other issues — outdated sockets, loose connections, and improper grounding. A lighting assessment catches all of it.

Surge Protection Risk Assessment
80% of surge damage comes from inside your home — not storms. Select everything you own to see how much you have at risk and whether whole-home protection makes financial sense.

The hidden threat: 80% of surge damage comes from inside your home — your HVAC, refrigerator, and appliance motors cycling on and off generate transient voltage spikes constantly. It's not about waiting for a storm.
Silent lifespan killer: Repeated transient stress causes cumulative damage to IC components and semiconductors. Appliances fail years early and it gets misattributed to "normal wear." It isn't.

Your HVAC alone — protected — is worth $2,471 in deferred replacement costs. Surge protection pays for itself before you ever need to use it.
