Hatch Mechanical in Chattanooga: EV-Ready Electrical Upgrades for Home Charging
Hatch Mechanical is a licensed mechanical contractor that handles residential electrical work tied to EV charger installation, with particular focus on the 200-amp panel upgrades and dedicated circuits that newer charging equipment demands. The company operates across Hamilton County and serves homeowners moving from gas to electric vehicles who discover their existing service cannot safely support Level 2 home charging without substantial panel work.
What Hatch Mechanical actually does
Hatch Mechanical evaluates residential electrical systems for EV readiness, then sizes and installs the dedicated circuits and breakers that Level 2 chargers require. A Level 2 charger pulls 30 to 50 amps continuously; most homes built before 2010 have 100 or 150-amp main panels that cannot safely accommodate this without reducing capacity elsewhere. Hatch assesses whether your current panel has available breaker slots, whether your service entrance and utility lines support an upgrade, and whether your home's wiring gauge matches the amperage. The company pulls all required permits through the City of Chattanooga and schedules inspections before and after work. They do not install the charger itself; that comes from the charger manufacturer or a specialized EV installer, but without the electrical foundation Hatch provides, those installers cannot legally proceed.
Services and pricing
Hatch charges $125 per hour for standard electrical work, with most EV prep jobs falling between $1,500 and $3,500 depending on whether a main panel upgrade is needed. A simple job, where your existing panel has an open 50-amp breaker and the charger location is close to the panel, runs closer to $1,200 to $1,800. If you need a new 200-amp main panel because your current service is undersized, add $2,000 to $3,500 for the panel itself, labor, and permit fees. Hatch requires a $500 deposit to schedule work and confirm the permit application. Call ahead for a site evaluation; many homeowners assume they need a full panel upgrade when a sub-panel or circuit reroute will suffice, and paying $200 for an assessment often saves $2,000 later.
How Hatch compares to other Chattanooga contractors
Other licensed electricians in Chattanooga, such as Second Generation Electric and Mtn State Electric, also perform EV charger prep work. Second Generation tends toward larger commercial projects and may take longer for residential slots. Mtn State Electric quotes higher hourly rates (around $150 per hour) but has faster turnaround on inspections. Hatch's advantage lies in its willingness to do hybrid jobs: if your panel is marginal, Hatch will sometimes relocate existing circuits to free capacity rather than upgrade the entire panel, a move that saves time and cost but requires more diagnostic work upfront. Choose Hatch if you want someone to problem-solve around your existing infrastructure; choose Second Generation if you need quick scheduling for a straightforward new panel; choose Mtn State if budget is secondary to speed.
Who this fits and who it does not
Hatch suits homeowners with older Chattanooga homes who want to install Level 2 charging but are uncertain whether their electrical service will allow it. The company is particularly useful if your home is on older copper wiring or if you have a mix of 100 and 150-amp panels from different eras of renovation. It does not suit anyone who only needs a standard 120-volt outlet adapter; that is plug-and-play and does not require a contractor. It also does not suit builders or large-scale commercial EV fleet projects, which require different licensing and experience.
What the first visit involves
Call Hatch with your charger model number and your home's age and electrical panel location. They will schedule a no-cost walkthrough, usually within three to five business days. During the visit, a technician opens your main panel, photographs the breaker configuration, checks the gauge of existing wires, and confirms whether your utility service can support an upgrade. They will identify whether you need 50, 60, or 100 additional amps. After the visit, Hatch emails a written quote with a line-item breakdown: panel upgrade cost (if needed), circuit installation, permits, labor, and timeline. Once approved, they submit the permit to the City of Chattanooga, which typically approves residential electrical permits within 7 to 10 business days. Work itself takes one to two days. A city inspector must sign off before your charger installer can connect the equipment.
Hours, parking, and logistics
Hatch operates Monday through Friday, 8 a.m. to 4:30 p.m., with emergency calls accepted during business hours. Saturday appointments are available for an additional $150 fee; call ahead to confirm availability. They keep three service vehicles in Chattanooga and typically arrive within a two-hour window on the scheduled date. Permits cost $50 to $80 and are paid to the City of Chattanooga, not to Hatch; Hatch handles the paperwork. Chattanooga's electrical inspection office, located at 921 East 11th Street, operates by appointment Monday through Friday; confirm inspection dates before scheduling your charger purchase.
Hatch Mechanical fills the gap between general electricians and EV charger retailers. Chattanooga has more than 800 registered EVs as of 2024, and nearly all require panel work before home charging is possible. Hatch does the unsexy but essential work that makes the charger installation happen.
