EV Charger Installation FAQs
As electric vehicle adoption grows across Houston, many property owners are exploring charging solutions, but they have important questions before getting started. Below, we’ve answered the most common and highly searched questions about EV charger installation, permitting, panel capacity, and daily use.
The right EV charger depends on your vehicle, driving habits, and property layout. Level 2 chargers are the most popular option for both residential and commercial use. They provide a faster, more practical charging experience than standard wall outlets and can be installed indoors or outdoors.
For businesses or fleets, DC fast chargers may be the better fit, delivering high-speed charging for multiple vehicles in public or high-turnover environments. Colwell Electric evaluates your power needs, existing electrical capacity, and future goals to recommend the best setup for your location.
Installation costs typically range from $500 to $2,500, depending on charger type, wiring distance, and panel upgrades. Residential installs are usually more straightforward, while commercial properties may require trenching, load management, or dedicated circuits.
Colwell Electric provides transparent quotes based on an on-site or virtual assessment. We walk you through every line item and ensure your installation meets local code, brand specifications, and your long-term charging needs.
You might. Many older homes and buildings don’t have enough available amperage to safely support a Level 2 charger, especially when paired with HVAC, appliances, or other large loads. If your panel lacks capacity, we’ll recommend and install an upgrade that aligns with your usage.
Our team handles full panel upgrades, subpanel installations, and circuit assessments in-house. We’ll make sure your system is safe, future-ready, and compliant with NEC and City of Houston requirements.
Yes, most Level 2 and commercial EV chargers are rated for outdoor use. These units are weather-resistant, sealed, and tested for exposure to rain, heat, and debris. Outdoor installations are common for garages, driveways, parking lots, and fleet depots.
We ensure proper placement, GFCI protection, and secure mounting for every outdoor installation. Whether you’re charging overnight at home or offering access to customers, Colwell Electric installs systems that perform in Houston’s toughest conditions.
Most residential installations are completed in one day, assuming no panel upgrade or trenching is required. Commercial installs may take longer depending on system size, permitting, and utility coordination.
After your assessment, Colwell Electric provides a clear installation timeline. We manage the full process, including permitting, inspection, and system testing, so there are no surprises, just a clean, code-compliant setup that’s ready to use.
