If you drive an EV in the Denver metro area, a home charger is the single upgrade that changes daily ownership the most. Instead of planning your week around public charging stations, you plug in at night and wake up to a full battery. At Impact Energy & Roofing, we install home EV chargers across Denver, Centennial, Aurora, and Pueblo, and we handle every step from the initial electrical load assessment to the final inspection. This guide explains how home charging actually works, why a 240-volt Level 2 charger is the right choice for most drivers, and what to expect from a professional installation along Colorado's Front Range.
Level 2 vs. Level 1 Charging: What Is the Difference?
The difference comes down to voltage and speed. Level 1 charging uses a standard 120-volt household outlet and the cable that came with your car. It adds roughly 3 to 5 miles of range per hour, which means a full charge can take more than a day. Level 2 charging uses a dedicated 240-volt circuit, the same type that powers an electric dryer or oven, and adds about 20 to 40 miles of range per hour. For most EVs, that is enough to fully recharge overnight. If you drive daily and want your car ready every morning, Level 2 is the practical choice.
How Long Does It Take to Charge an EV at Home?
With a Level 2 charger, most electric vehicles go from nearly empty to full in about 4 to 10 hours, depending on the size of the battery and the charger's output. Because that easily fits inside an overnight window, you rarely arrive at a low battery in the morning. Most Denver drivers simply plug in when they get home and top off during off-peak hours. A standard 120-volt outlet, by contrast, may only replace a partial day of driving overnight, which is why it works as a backup but not as a primary charging method for daily drivers.
Why a Load Assessment Comes First
Before any charger goes on the wall, the right setup depends on your electrical panel. A Level 2 charger draws a significant amount of power, so we start with a load assessment to confirm your home can handle it safely. This evaluation looks at your panel's total capacity, how much of it your existing appliances already use, and whether there is room for a new 240-volt circuit. Many Denver-area homes are ready as-is, while older homes may need a panel upgrade or a smart load-management device that balances the charger with the rest of the house. Skipping this step is the most common cause of failed inspections and tripped breakers, which is why we never treat it as optional.
What Does Home EV Charger Installation Involve?
A professional installation is more than mounting a box and running a wire. Our process is designed to keep you safe, code-compliant, and charging reliably for years.
Load assessment and site walk to confirm capacity and choose the best charger location.
Charger selection based on your vehicle, driving habits, and whether you want Wi-Fi and scheduling features.
Dedicated 240-volt circuit and wiring run from your panel to the charger location.
Mounting and hookup of the charger, indoors in a garage or outdoors in a weather-rated enclosure.
Permitting and inspection so your installation meets local Colorado electrical code.
Testing and walkthrough so you leave knowing exactly how to use your new charger.
How Much Does a Home EV Charger Cost in Denver?
Total cost depends on three main factors: the charger unit you choose, the distance from your electrical panel to the charger location, and whether your panel needs any upgrades. A straightforward installation where the panel is close to the garage and has spare capacity sits at the lower end. Longer wiring runs, trenching for detached garages, or a panel upgrade will add to the price. The most accurate way to budget is a free consultation and load assessment, which lets us give you a firm quote instead of a rough guess. It is also worth checking for local utility rebates and federal tax incentives, which can meaningfully lower your out-of-pocket cost.
Charging Through Colorado Winters
Front Range winters matter for EV owners. Cold temperatures temporarily reduce range and slow charging, so home charging becomes even more valuable when the weather turns. With a Level 2 charger in your garage, you can precondition the cabin and battery while still plugged in, which preserves range and improves comfort on cold Denver mornings. Outdoor installations are fully weather-rated for snow and freezing temperatures, and we position and protect every component with Colorado's climate in mind.
Where We Install: Denver, Centennial, Aurora, and Pueblo
Impact Energy & Roofing installs home EV chargers throughout the Denver metro area and along the Front Range. Whether you are in a newer Centennial subdivision, an established Denver neighborhood, a growing Aurora community, or a home in Pueblo, we handle the assessment, permitting, and installation from start to finish. Working with a local team means your installer understands regional utility requirements, local permitting, and the electrical realities of homes in each of these areas.
Frequently Asked Questions
Do I really need a Level 2 charger, or is a regular outlet enough?
A standard 120-volt outlet only adds a few miles of range per hour, which is fine for very low-mileage drivers or as an occasional backup. For anyone who drives daily, a 240-volt Level 2 charger is the practical choice because it fully recharges most EVs overnight.
How many miles of range does a Level 2 charger add per hour?
A 240-volt Level 2 charger adds roughly 20 to 40 miles of range per hour, depending on your vehicle and the charger's output. That is typically enough to fully charge most EVs overnight.
Will my electrical panel support an EV charger?
Many homes can support a Level 2 charger without changes, but it depends on your panel's capacity and existing load. That is exactly what our load assessment confirms before installation. If an upgrade or smart load-management device is needed, we will explain your options clearly.
Can the charger be installed outdoors?
Yes. We install weather-rated chargers designed for outdoor use, which is well suited to Colorado's snow and freezing temperatures. We position and protect each unit so it performs reliably year-round.
