Yes. Aaron was born and raised in Tucson and has particular familiarity with the more electrically challenging older structures found in and around the city, such as adobe and straw bale, along with the best practices that come with the desert’s unique building needs.

Yes. If a solar contractor left you high and dry, we know the ins and outs of these complex systems and can repair yours or figure out what you need to get it back on track. We also design new systems around how you actually use power.

Yes, it’s a specialty. Off-grid living is a particular interest of Aaron’s, and we’re especially skilled with off-grid solar systems, wells, pumps and battery backup, including systems that run on alternative fuel.

Yes. From single-head units to ceiling cassettes to multi-zone systems, we install and repair mini-splits across Tucson.

A breaker trips to protect the wiring. The usual causes are an overloaded circuit (too many devices), a short circuit, or a ground fault (often from moisture or a damaged cord). Unplug everything on that circuit and reset the breaker. If it trips again right away with nothing plugged in, or it trips repeatedly, there is a wiring or breaker problem and you should call an electrician. Never swap in a larger breaker to stop the tripping, since that can let the wire overheat.

Motors draw a large surge of current when they start, which can briefly dim lights, especially on a shared circuit. A quick, slight dim is often normal. Frequent or heavy flickering can point to loose connections, an overloaded circuit, an undersized service, or a utility-side issue, so it is worth having an electrician check it.

No. Warmth, browning, or scorch marks mean heat is building at the connection, usually from a loose wire, a worn outlet, or an overloaded circuit. Stop using it, unplug what is in it, turn off the breaker, and call an electrician. If you smell burning or see smoke or sparks, shut off power and call 911 if there is any sign of fire.

Start with two checks: press RESET on any GFCI outlet nearby (in bathrooms, kitchens, garages, or outdoors, since one can control others), and look in the panel for a tripped breaker. If both are fine, the cause is often a loose or failed connection in a wall box or outlet. That needs an electrician to trace safely.

A tingle usually means electricity is finding an unintended path, such as an ungrounded or miswired outlet, a faulty appliance, or moisture. Stop using the item and have it checked. Even small shocks can signal a fault that could cause a more serious shock or a fire.

They can be. Aluminum branch wiring, common in some homes built in the 1960s and 1970s, can loosen and oxidize at connections and create fire risk. Approved repairs include special connectors or crimps, or rewiring. Federal Pacific (Stab-Lok) and Zinsco panels have a documented history of breakers that fail to trip. If your home has either, have an electrician evaluate it and plan for replacement or repair.

Common signs include frequent breaker trips, no open slots for new breakers, a fuse box, or an older panel brand with known problems. Upgrades are also common when adding an EV charger, heat pump, addition, or hot tub. An electrician does a load calculation to decide if your current service can handle what you have and what you plan to add.

Warning signs include repeated tripping, dimming lights, warm plugs or cords, buzzing, and heavy reliance on extension cords or power strips. As a rule, continuous loads should stay under about 80% of the breaker rating. For example, a 15-amp circuit is best kept to roughly 12 amps (about 1,400 watts) of steady use.

Usually yes, if the main panel and service have enough capacity. A subpanel is common for garages, workshops, and additions. The job needs a load calculation, correct wire and breaker sizing, proper grounding, and typically a permit and inspection.

A Level 2 (240-volt) home charger commonly runs from around $500 to $2,500 installed, though prices vary by region. The biggest factors are the distance from the panel to the charging spot, whether the panel has spare capacity, and the charger itself. If the panel needs an upgrade, the total goes up. A written local quote is the only reliable number.

Yes. Ceiling fans need a fan-rated box that can support the weight and movement. Recessed lights in insulated ceilings must be IC-rated. Dimmers should be matched to the bulbs, since LED fixtures need LED-compatible dimmers to avoid flicker or buzzing.

A whole-home surge protector installs at the panel and diverts voltage spikes from lightning, utility switching, and large appliances cycling on and off. It is generally worth it if you have expensive electronics and appliances. It reduces risk but cannot guarantee protection from a direct lightning strike, and it works best paired with plug-in surge protectors for sensitive devices.

Yes, and a properly installed transfer switch or interlock is essential. It keeps generator power from feeding back into the utility lines, which can seriously injure or kill line workers. Never plug a generator into a wall outlet using a dual-male cord. Installations typically need a permit, and portable generators must run outdoors, well away from windows, because of carbon monoxide.

Yes. New outlets can be added to an existing circuit if it has capacity, or on a new circuit for heavier use. USB outlets replace standard receptacles and are a simple upgrade. An electrician can run wiring inside walls or use surface-mounted options where opening walls is impractical.

A GFCI detects tiny current leaks and shuts power off in a fraction of a second to prevent electrical shock. It is required in wet or damp areas such as bathrooms, kitchens, garages, basements, laundry areas, and outdoors. An AFCI detects dangerous arcing in wiring and cords to prevent fires, and is required in bedrooms and many other living areas under newer codes. Dual-function breakers provide both. Requirements depend on the code edition your area has adopted, and both types should be tested regularly using their test buttons.

Current codes require hardwired, interconnected smoke alarms with battery backup in new construction and major renovations, so when one sounds they all sound. Requirements for existing homes vary by location. Carbon monoxide alarms are generally needed near sleeping areas and on each level of the home.

Two-prong (ungrounded) outlets are not automatically dangerous, but they lack a safety ground. Options include GFCI protection on those circuits or rewiring. Knob-and-tube wiring is more of a concern, particularly when it is covered by insulation, has been modified, or is overloaded by modern use. Insurers may also restrict coverage. An inspection will tell you if you need a partial or full rewire.

Permits are usually required for new circuits, panel changes, service upgrades, EV chargers, generators, and additions. Simple like-for-like swaps of an outlet, switch, or light fixture often do not need one, but rules vary by city and county. Licensed electricians normally handle permits. Unpermitted work can cause problems with insurance claims and when selling a home.

It depends on the job. Troubleshooting and small repairs are often billed hourly, sometimes with a service-call fee. Defined projects like installing a circuit, fixture, or charger are commonly quoted at a flat rate. Rates vary widely by region and complexity, so ask for a written estimate that lists labor, materials, and permit fees.

Yes. Light The Way Electrical is licensed, bonded and insured under Arizona ROC #359885. You can verify any Arizona contractor’s license with the Arizona Registrar of Contractors at roc.az.gov.

A reputable electrician should be licensed in your state or locality, carry liability insurance, and have workers’ compensation coverage for employees. Ask for their license number and verify it with the licensing board, and ask for a certificate of insurance. That protects you if something goes wrong on the job.

Many homeowners safely replace a switch, outlet, or light fixture after turning off the breaker and confirming the power is off with a voltage tester. Panel work, new circuits, aluminum or old wiring, and anything you are unsure about should go to a licensed electrician. Some areas also restrict or require permits for homeowner electrical work, so check local rules first.

Simple jobs like a fixture, outlet, or dimmer can take an hour or two. A new circuit or charger may take a few hours to half a day. A panel upgrade often takes most of a day and needs power off for several hours, sometimes with utility coordination. A good electrician will tell you the expected outage in advance so you can plan around refrigerators, medical equipment, and work-from-home needs.

Many electricians offer 24/7 emergency service at a higher rate. Free estimates are common for larger projects, while troubleshooting or diagnostic visits are often charged. If you see sparks, smell burning, or suspect a fire, turn off the main breaker if it is safe to do so and call 911 before calling an electrician.
