Why Pasadena Homeowners Trust LMH Services for EV Charger Installation
Licensed & Insured Electricians
Every EV charger installation is performed by a licensed electrician who understands the unique electrical demands of high-amperage, long-runtime circuits. Our team carries full liability coverage and adheres to all NEC (National Electrical Code) and local building code requirements. We pull permits, coordinate inspections, and leave you with documentation that protects your home’s electrical integrity and safety.
Site-Specific Assessment Before Any Work
Proper EV charger installation starts with understanding your home’s electrical system. We evaluate your main electrical panel capacity, existing load distribution, available breaker space, wire gauge requirements, and distance from panel to charger location. This assessment prevents costly surprises—like discovering you need a panel upgrade after the fact—and ensures we recommend the right charger size and installation approach.
Fast, Clean, Professional Installation
Most Level 2 charger installations complete in a single day (4–6 hours). Our process includes breaker installation, conduit running, charger mounting, full circuit testing, and thorough cleanup. We respect your home, protect your flooring and walls, and leave you with a fully functional, inspected charger and complete documentation.
Transparent Pricing & Flexible Financing
We provide upfront quotes with no surprises. If a panel upgrade is needed, we’ll explain the cost and timeline separately. We also offer financing through our partner lenders (Wisetack), making it easy to spread charger installation costs over time without straining your monthly budget.
Multiple Charger Options & Expert Guidance
We install and service Tesla Wall Connector, Siemens, Eaton, Leviton, and other leading brands. Rather than pushing one brand, we discuss your vehicle type, charging habits, and preferences to recommend the best fit. If you want app connectivity, prefer a compact design, or need weatherproof outdoor capability, we’ll guide you to the right unit.

What Pasadena-Area Homeowners Say
How EV Charger Installation Works
From the initial site assessment to final testing and inspection, every step is documented and done to code — so your new charger performs safely from day one.
We visit your home to inspect your electrical panel, measure distances from panel to garage, and identify the best charger location. We verify panel amperage and available breaker capacity, discuss your vehicle and charging habits, and explain Level 2 vs. DC Fast Charging options. This step ensures we order the right equipment and avoid surprises.
- Panel inspection: main service size, existing load, breaker availability
- Distance measurement from panel to proposed charger location
- Conduit routing: wall-mounted vs. underground vs. overhead
- Charger type recommendation based on vehicle and home setup
- Code review: ensures compliance with local electrical ordinances
Before any installation, we file for electrical permits if required by your city or county. This step protects you legally and ensures inspectors approve the work. We coordinate permit timing so installation isn’t delayed.
- Obtain building permit (if required by local authority)
- Prepare electrical drawings showing panel, breaker size, and charger specs
- Verify utility company requirements for high-amperage circuits
- Schedule city/county electrical inspection if needed
Our licensed electrician installs a new breaker in your panel rated for the charger (typically 40–50 amps). We run THHN copper wire or conduit from the breaker to the charger location, following code for wire gauge, spacing, and grounding. All connections are secure, labeled, and inspected.
- Install new breaker in main panel
- Run properly-gauged copper wire or conduit (UF-B or THHN)
- Install conduit supports and cable management
- Ground the circuit per NEC requirements
- Test continuity and amperage at each junction
The charger is securely mounted at the chosen garage location (typically 4–5 feet high for easy access). We connect the hardwired circuit to the charger’s terminals, install the mounting hardware, and seal any conduit penetrations to prevent moisture and pests.
- Mount charger bracket securely to wall or pedestal
- Connect copper wire to charger terminals
- Install weatherproof cover plates and conduit seals
- Verify no kinks or sharp bends in wire runs
- Test operational readiness: power delivery, button response
Before we leave, we perform comprehensive testing to confirm safe operation. We verify voltage, amperage, and ground integrity using professional test equipment. If a building permit was filed, we schedule the city or county inspection and address any inspector notes before final sign-off. You receive complete documentation, charger manuals, app setup instructions, and our one-year workmanship warranty.
- Perform load test: verify 240V delivery, proper amperage output, and ground resistance
- Test pilot signal and safety interlocks (charger-to-EV communication)
- Contact inspector if required; address any corrections before final approval
- Provide homeowner with charger manual, warranty, and electrical permit receipt
- Set up app/software account if applicable (Tesla, Siemens, Eaton, etc.)
- Review daily charging best practices, scheduling tips, and emergency procedures
- Document all test results, breaker info, and wire gauge on work order for your records

EV Charger Installation & Service FAQs
A Level 2 charger typically requires 40–50 amps at 240V. Most homes built in the last 20–30 years have adequate capacity, but older homes or those with large HVAC systems may need a panel upgrade. We assess this during the site visit and recommend solutions if needed.
Most Level 2 charger installations complete in one day (4–6 hours). Time varies based on distance from panel to charger, whether conduit runs through walls or outdoors, and if a permit inspection is required. We’ll give you a timeline during the consultation.
Requirements vary by city. Pasadena, La Porte, and Baytown each have their own codes. We handle permit coordination—it’s part of our service and ensures your installation is compliant and future-proof.
Yes, but with restrictions. You’ll need HOA or landlord approval and access to dedicated parking. We can discuss feasibility during a consultation and explore options like portable Level 2 chargers if wall-mounting isn’t allowed.
We provide panel upgrade services. Depending on your current service (100-amp, 150-amp, 200-amp), we can upgrade to a larger panel or add a subpanel near your charger location. This adds cost and time but is often simpler than running long wire runs from a distant panel.
Yes. We troubleshoot issues like failed charging sessions, error codes, connectivity problems, and faulty outlets. We also perform annual safety inspections and handle warranty claims with manufacturers.
We install and service Tesla Wall Connector, Siemens, Eaton, Leviton, and other major Level 2 brands. If you have a specific charger in mind, let us know and we’ll confirm compatibility.
Yes, with proper weatherproofing and NEMA-rated components. Outdoor installations require weatherproof enclosures, corrosion-resistant hardware, and UV-rated conduit. We handle all weatherproofing to ensure longevity.
We warranty our installation workmanship for one year. The charger itself carries the manufacturer warranty (typically 2–5 years). We provide full documentation with your charger purchase.
No. Level 2 chargers require grid power. Some advanced systems have battery backup capability, but most home chargers won’t operate during an outage. If you’re interested in backup power, we can discuss home battery or generator options.
