Electrician in Tempe, AZ: Your Trusted Local Experts

Your electrical panel, also called the circuit breaker box or breaker panel, controls every circuit in your home. When it fails or falls short of your home’s electrical needs, the effects show up throughout the house: breakers that trip under normal load, circuits sharing capacity they should not, and outlets delivering inconsistent power.

Older Tempe homes, particularly those built between the 1960s and 1990s, often have 100-amp panels. A 100-amp service was adequate for a home with a gas range, no pool, no EV, and window AC units. A modern Tempe home with central air conditioning (typically a 4-ton unit drawing 14 to 18 amps at 240 volts), a pool pump (5 to 10 amps at 240 volts), a Level 2 EV charger (32 to 48 amps at 240 volts), and standard household loads will exceed 100-amp capacity under normal use.

Our electricians inspect your panel, identify the problem, and recommend the right solution: a breaker replacement, an electrical panel repair, or a full panel upgrade to 200-amp or 400-amp service. We also identify and replace dangerous legacy panels, including Federal Pacific Electric (Stab-Lok) and Zinsco panels, which have well-documented breaker failure and fire risk issues and are still found in some Tempe homes.

Electrical panel upgrades in Tempe require a permit from the City of Tempe and coordination with your utility, APS or SRP, for the service entrance upgrade. We handle both. Expect the full panel upgrade process, from permit application to utility sign-off and final inspection, to take 2 to 4 weeks, depending on utility scheduling.

Signs your panel needs attention:

• Breakers that trip under normal household loads
• A circuit breaker that trips and will not reset, or resets and trips again immediately
• Breakers that feel warm or hot to the touch
• Rust, corrosion, or moisture inside the panel enclosure
• A burning smell near the circuit breaker box
• Your panel is a Federal Pacific Electric or Zinsco brand
• You are adding a major new load: EV charger, pool, hot tub, or additional HVAC equipment

Arizona ranks among the top states for electric vehicle adoption, and Tempe homeowners are adding EVs at a rapid pace. A standard 120-volt outlet, sometimes called a Level 1 charger, delivers roughly 3 to 5 miles of range per hour of charging. A near-empty battery on most EVs takes 40 or more hours to fully charge at Level 1. That is not a practical home charging setup for daily driving.

A Level 2 home charging station operates at 240 volts and typically draws 32 to 48 amps, depending on the charger model. Most EVs charge fully overnight at Level 2, adding 25 to 30 miles of range per hour. For a Tesla Model 3, a Ford F-150 Lightning, or a Rivian R1T, a Level 2 car charging station is the standard home solution.

Installing a Level 2 EV charger at your Tempe home requires:

• A dedicated 240-volt circuit, typically 40 to 50 amps
• Adequate capacity in your main panel (a 100-amp panel serving a fully loaded home often does not have room for a 40-amp EV circuit without a panel upgrade)
• A conduit runs from the panel to the garage or carport location
• A NEMA 14-50 outlet or hardwired EVSE connection, depending on the charger
• A permit from the City of Tempe Building Services Department

We assess your panel’s available capacity before recommending a charger. If your panel is at or near capacity, we will discuss your options: a panel upgrade, a load management device, or a subpanel in the garage. The federal residential clean energy tax credit (IRS Form 8911) covers up to 30% of the cost of a home EV charging station installation through 2032. We provide only residential and commercial EVSE installations.

Tempe’s monsoon season runs from June through September. Lightning, high winds, and sudden storms knock out power for hours or longer. In a city where summer temperatures regularly exceed 110°F, a home without air conditioning becomes dangerous within hours for elderly residents, young children, and pets.

A Generac home backup generator is permanently installed outside your home, connected to your natural gas or propane supply, and wired through an automatic transfer switch. When utility power from APS or SRP drops, the generator detects the outage and starts automatically, typically within 10 seconds. No manual setup. No extension cords. No fuel runs during a storm.

Generac generator sizing for Tempe homes:

• 10 kW: Covers essential circuits: lights, refrigerator, select outlets, fans. Does not power the central AC.
• 18 kW: Powers most of the home, including one central AC unit (3 to 4 tons). Recommended minimum for Tempe homes with a single AC system.
• 22 kW: Whole-home coverage including two AC units, well pump, and all standard loads.
• 24 kW and above: Large homes with multiple high-draw systems.

In Tempe’s summer heat, keeping at least one AC unit running during a power outage is a health priority, full stop. We recommend a minimum of 18 kW for any Tempe home with occupants present during a summer outage. A full generator installation includes site assessment, connection to natural gas or propane lines, automatic transfer switch wiring, electrical permit, and utility notification to APS or SRP. We also perform annual generator maintenance and service existing Generac systems.

Tempe sits in one of the most electrically active monsoon corridors in the United States. The Phoenix metro area averages more than 30 thunderstorm days per year, and monsoon season brings lightning strikes, utility switching events, and sudden power restoration after outages. Each of these sends a surge through your electrical system.

A whole-house surge protector, also called a Type 2 SPD (Surge Protective Device), installs at your main electrical panel and intercepts surges before they reach your devices and appliances. A point-of-use power strip protects only the devices plugged directly into it, with no protection for hardwired equipment: your HVAC system, water heater, pool equipment, smart home devices, or any appliance on a dedicated circuit.

The cost to replace a modern variable-speed HVAC system in Tempe ranges from $5,000 to $12,000. A smart home hub, panel, or automation system adds thousands more. A whole-house SPD installed at your panel costs a fraction of that and protects everything in the home simultaneously.

After a power outage, the moment utility power is restored often produces a surge as voltage stabilizes. This is one of the most common causes of appliance damage in Tempe homes following a monsoon storm. We install whole-house surge protection as a standalone service or as part of a panel upgrade. We recommend it for any Tempe home with smart home products, newer HVAC equipment, or high-value electronics.

Arizona has one of the highest rates of residential pool ownership in the country, and many Tempe homes have pools. Pool electrical systems are governed by NEC Article 680, which requires GFCI protection, proper bonding, and specific wiring methods for all pool equipment.

If your pool pump has lost power, your pool lights are flickering, or your GFCI breaker keeps tripping, our electricians diagnose and repair the issue. We also handle new pool wiring, bonding grid installation, and equipment circuit upgrades. All pool electrical work in Tempe requires a permit and inspection, and we manage both.

Common pool wiring issues we see in Tempe homes include failed GFCI breakers for pool equipment, bonding wire corrosion from years of exposure to pool chemistry, and pump motor circuit failures during peak summer use. Pool lights in older Tempe homes are sometimes wired with non-compliant methods that predate current NEC Article 680 requirements. We identify and correct these conditions during any pool electrical service call.

Tempe’s housing stock spans more than six decades, and the wiring inside older homes tells that story. If your home was built before 1970, there is a real chance the electrical wiring inside your walls was never designed for the loads you are putting on it today.

Two wiring types require particular attention in older Tempe homes.

Knob and tube wiring was the standard in homes built before the 1940s. This system runs separate hot and neutral wires through ceramic knobs and tubes, with no ground wire. Knob and tube wiring cannot support grounded outlets, GFCI protection, or the electrical loads of today’s appliances. Insulating over knob and tube wiring in an attic during an energy upgrade traps heat and accelerates insulation breakdown. Most Arizona homeowner’s insurance carriers will not write a policy on a home with active knob and tube wiring, or they charge significantly higher premiums. If your Tempe home has knob and tube wiring, a full house rewire is the correct long-term solution.

Aluminum branch circuit wiring, common in homes built between 1965 and 1975, requires AL/CU-rated devices at every connection point. When aluminum wiring connects to devices rated only for copper, the connection loosens over time due to different expansion rates, generating heat and creating a fire risk. The CPSC-recommended remediation is pigtailing: attaching a short length of copper wire to the aluminum at each outlet, switch, and fixture connection point.

A full house rewire involves running new copper wiring throughout the home, replacing the panel if needed, and bringing all circuits up to current NEC code. In Tempe, a full rewire requires a permit from the City of Tempe Building Services Department and inspections at rough-in and final stages. Permit timelines for residential electrical work in Tempe typically run 5 to 10 business days through the city’s online portal. We manage the entire process, from permit application through final inspection sign-off.

Signs your Tempe home needs a rewiring assessment:

• Outlets or switches that feel warm to the touch
• Lights that flicker or dim when appliances run
• Breakers that trip frequently without an obvious cause
• Outlets with only two prongs (no ground) throughout the home
• A home built before 1970 with no documented electrical updates
• Burning smell without an identified source

Yes. A GFCI (Ground Fault Circuit Interrupter) outlet monitors the flow of electricity through a circuit and shuts off power within milliseconds if it detects an imbalance. That imbalance happens when current flows somewhere it should not, such as through water or a person. Under NEC Section 210.8, GFCI protection is required in kitchens, bathrooms, garages, all outdoor locations, crawl spaces, unfinished basements, and near pools, hot tubs, and wet bars.

Many older Tempe homes lack GFCI outlets in several required locations. This is a code compliance issue and a genuine safety risk. Our electricians assess your home’s outlet layout, identify locations that require GFCI protection, and install the correct devices. A standard GFCI outlet installation takes less than an hour per location, and no permit is required for a like-for-like replacement.

Faulty outlets are one of the most common electrical issues we see in Tempe homes. An outlet stops working for several reasons:

• A GFCI has tripped and needs to be reset (check for a GFCI outlet nearby, even in another room, as one GFCI often protects multiple downstream outlets)
• A breaker has tripped at the panel
• The outlet has failed internally, which happens with age and heat exposure
• A loose wire connection at the outlet or in the junction box behind it
• Aluminum wiring that has loosened at the connection point

Before calling us, press the Reset button on any GFCI outlet in the same area. If that does not restore power, or if the outlet feels warm, shows discoloration, or sparks when you plug something in, call our team. Faulty outlets left unaddressed generate heat inside the wall and represent a fire risk over time.

We also install AFCI (Arc Fault Circuit Interrupter) breakers, which are required by NEC Section 210.12 for most living areas in new construction and electrical renovation projects. AFCI breakers detect the electrical signature of an arc fault, a dangerous condition that standard breakers do not detect, and shut down the circuit before a fire starts.

A ceiling fan running counterclockwise in summer creates a wind-chill effect, allowing you to raise your thermostat by 4°F without changing your comfort level, according to the U.S. Department of Energy. In Tempe, where cooling costs are highest from May through October, that translates directly to lower APS or SRP bills.

Installing a ceiling fan where no fixture previously existed requires running a new circuit or extending an existing one, installing a fan-rated electrical box (standard light fixture boxes are not rated for the weight and movement of a fan), and running a proper switch leg for independent fan and light control. Homes wired before the 1990s often have only a single-conductor switch leg to ceiling fixtures, which limits independent speed and light control unless a new wire run or wireless control system is added.

Our electricians handle the full installation: box replacement or new rough-in, wiring, fan mounting, and switch installation. We also assess whether your existing circuit is appropriately sized. A 14 AWG wire on a 15-amp circuit handles a single ceiling fan without issue, but adding multiple fans or combining them with other loads requires a proper load calculation before proceeding. If you are replacing an existing ceiling fan, the process is straightforward. If you are adding a fan to a room without a prior fixture, plan for a half-day installation that includes the necessary wiring.

LED bulbs use 75% less energy than incandescent bulbs and last 15 to 25 times longer, according to the U.S. Department of Energy. In a Tempe home where lights run year-round and cooling costs are already high, reducing heat output from lighting fixtures also reduces the load on your AC system. A full LED lighting upgrade addresses both energy efficiency and comfort.

A proper LED upgrade involves more than swapping bulbs. Older recessed cans, track lighting fixtures, and decorative fixtures often require compatible LED trim kits or full fixture replacements to work correctly with LED technology. Dimmer switches installed for incandescent bulbs frequently cause LED lights to flicker or buzz unless replaced with LED-compatible dimmers. We assess your existing fixtures and switches and recommend the right products for each location.

We install Energy Star-rated fixtures and LED-compatible dimmer switches throughout Tempe homes. Energy Star-certified LED fixtures meet strict efficiency and performance standards set by the U.S. EPA and, in many cases, qualify for utility rebates through APS and SRP.

Outdoor LED upgrades are particularly valuable in Tempe. Exterior fixtures run long hours in a harsh UV environment, and LED fixtures rated for outdoor use hold up significantly better than older halogen or incandescent alternatives. We install weatherproof LED fixtures, motion-activated security lights, and low-voltage landscape lighting systems that enhance both safety and curb appeal in South Tempe neighborhoods such as Warner Ranch, The Lakes, and Royal Palms.

Yes. Smart home devices require more than a Wi-Fi connection. Smart switches, smart dimmers, smart thermostats, whole-home audio systems, and automated lighting controls all need proper wiring to function correctly and safely.

Standard smart switches require a neutral wire at the switch location. Many Tempe homes built before 1990 were wired with a switch loop, which carries only the hot wire to the switch and back, without a neutral. Installing a smart switch in this configuration requires either running a new wire or selecting a smart switch designed to work without a neutral. We assess your existing wiring before recommending a product, so you are not buying hardware that will not work in your home.

We also install smart panel systems that replace your standard circuit breaker box with a unit that monitors energy use by circuit, controls loads remotely, and integrates with solar or battery backup systems. These installations require a licensed electrician and a permit in Tempe. We install smart switches, smart dimmers, whole-home lighting controls, smart thermostats, and smart panel systems throughout the area. Every installation is wired to code and tested before we leave.

High-load 240-volt appliances, including your central air conditioner, electric range, and water heater, run on dedicated circuits. When these circuits fail in the middle of a Tempe summer, you are dealing with a health and safety concern, not a minor inconvenience.

Our electricians quickly troubleshoot and repair 240-volt circuits. Common causes include a failed double-pole breaker, a loose connection at the panel or appliance, or a wiring fault in the circuit. We identify the problem and restore power fast. Both your electric range and electric water heater run on 240-volt dedicated circuits. If one of these appliances loses power, check your panel for a tripped double-pole breaker. A tripped double-pole breaker sits in the middle position rather than fully on or off. If resetting the breaker does not restore power, or if the breaker trips again immediately, there is a deeper issue that requires hands-on diagnosis.

Yes. From recessed lighting and ceiling fans to outdoor security lights and landscape lighting, we handle all types of residential lighting work. South Tempe neighborhoods like Warner Ranch and The Lakes see strong demand for outdoor lighting upgrades and custom lighting installations that improve both security and curb appeal.

We install motion-activated lights, LED retrofits, dimmer switches, and custom lighting layouts tailored to your home. We also repair and replace existing fixtures that are flickering, dead, or simply outdated. Every lighting installation is wired to code with the correct wire gauge, box rating, and switch configuration for the fixture type and load.

Not every electrical problem announces itself clearly. Flickering lights, outlets that stop working, a breaker that trips once and never trips again, a room that loses power intermittently: these are the kinds of electrical issues that are easy to dismiss and harder to diagnose without the right tools and experience.

Our electricians use systematic electrical troubleshooting to identify the root cause, not the symptom. We test outlet voltage, check continuity throughout the circuit, inspect connections at the panel and at each device, and determine whether the problem is in the wiring, the device, or the panel. Many intermittent electrical problems trace back to a loose connection, which generates heat and resistance over time and can eventually cause a failure or fire.

Common electrical problems we troubleshoot in Tempe homes:

• Outlets that stop working for no apparent reason (often a tripped GFCI on the same circuit, even in another room)
• Lights that flicker when an appliance starts (often a loose neutral connection or an undersized circuit)
• A breaker that trips under normal load (overloaded circuit, failing breaker, or a wiring fault)
• Burning smell without a visible source (loose connection heating up inside a wall or junction box)
• One room or area losing power (a tripped breaker, a failed GFCI, or a wiring fault in the circuit)
• A circuit that works intermittently (almost always a loose connection at an outlet, switch, or junction box)

We diagnose first, then repair. That approach saves you money and makes sure the actual problem gets fixed.

An electrical safety inspection gives you a clear picture of the condition of your home’s electrical system. Our licensed electricians assess every major component: the service entrance, main panel, subpanels, branch circuits, outlets, switches, fixtures, and grounding system. We check for code compliance against the current NEC and Tempe’s local amendments, identify safety hazards, and provide a written summary of findings.

A home electrical inspection in Tempe covers:

• Service entrance condition and amperage rating
• Main panel and subpanel condition, breaker operation, and labeling
• Double-tapped breakers (two wires on a single breaker terminal, a code violation in most cases)
• GFCI protection in all required locations per NEC 210.8
• AFCI breaker installation in living areas per NEC 210.12
• Outlet grounding and polarity throughout the home
• Visible wiring condition in attic, crawl space, and accessible areas
• Aluminum wiring identification and connection condition
• Knob and tube wiring identification
• Smoke and CO detector placement relative to electrical hazards

When to schedule an electrical inspection in Tempe:

• Before purchasing a home (a general home inspector checks for visible issues; an electrical inspection goes deeper)
• If your home is more than 25 years old and has never had a dedicated electrical assessment
• Before starting a major home renovation or addition that will add new circuits or loads
• After a significant monsoon storm or lightning event near your home
• If you notice flickering lights, warm outlets, tripping breakers, or a burning smell without an identified cause
• Before installing a whole-home generator, EV charger, or pool equipment

Code compliance matters beyond safety. Unpermitted or non-code-compliant electrical work creates problems when you sell your home, affects your insurance coverage, and creates liability if an incident occurs. Our electricians identify existing non-compliant conditions and give you a prioritized list of what needs to be addressed, so you can make informed decisions about your home’s electrical needs.

1. Call or book online. Reach us 24/7 by phone. A real person answers every call. Tell us what is going on, and we will schedule a visit at a time that works for you.
2. On-site assessment. Our licensed electrician arrives at your Tempe home, inspects the issue, and gives you a clear explanation of what we found and what it will take to fix it.
3. Upfront pricing. Before any work begins, we walk you through the cost. You approve the work, and we get started. We quote by the job, not by the hour.
4. Expert service with permits handled. We complete the work, code it, pull any required permits from the City of Tempe, and schedule inspections as needed.
5. Final walkthrough. We test everything, clean up the work area, and make sure you are satisfied before we leave.

Yes, permits are required for most significant electrical work in Tempe. The City of Tempe Building Services Department requires permits for panel upgrades, new circuit installations, EV charger installs, standby generator hookups, pool and spa wiring, and service entrance changes. We pull all required permits on your behalf and coordinate inspections, so you do not have to navigate that process yourself. Skipping a permit on work that requires one creates problems when you sell your home, and affects your homeowner’s insurance coverage for related incidents. Residential electrical permits in Tempe typically process within 5 to 10 business days through the city’s online portal.

Your panel likely needs attention if it is more than 30 years old, if breakers trip frequently and will not reset, if you notice a burning smell or see scorch marks near the panel, or if your panel is a Federal Pacific Electric (Stab-Lok) or Zinsco brand. Both FPE and Zinsco panels have well-documented safety issues and are still found in some Tempe homes built in the 1960s and 1970s. A 100-amp panel is also typically insufficient for a modern Tempe home running central AC, a pool, an EV charger, and standard appliances. Our electricians inspect your panel and give you an honest assessment of whether a repair or a full replacement is the right move.

Most modern Tempe homes need at least a 200-amp panel. If you have or plan to add a pool, a Level 2 EV charger, multiple HVAC units, or other high-draw appliances, 200 amps is the minimum you should have. Homes with larger electrical loads often need a 400-amp service. The right answer depends on your current and planned usage. We assess your home’s specific needs before recommending a panel size, so you are not paying for more than you need or underestimating what your home requires.

Yes. A Level 2 charger (240 volts) charges most electric vehicles in 4 to 8 hours, compared to 40 or more hours on a standard 120-volt outlet. For Tempe homeowners who drive daily, that difference is significant. Arizona’s EV adoption rate continues to grow, and a Level 2 home charging station adds measurable value to your home. The federal residential clean energy credit covers up to 30% of the installation cost through 2032. We handle the full installation, including the permit required by the City of Tempe.

In Tempe’s summer heat, air conditioners run almost continuously, putting a sustained load on your electrical circuits. A breaker that trips repeatedly is telling you one of three things: the circuit is overloaded, the breaker itself is failing, or there is a wiring fault somewhere in the circuit.

An overloaded circuit is the most common cause. A 15-amp circuit can handle up to 1,800 watts continuously. A window AC unit alone draws 1,000 to 1,500 watts. Add other high-draw devices to the same circuit, and you will reliably trip the breaker. The solution is to redistribute loads or add a dedicated circuit.

A failing breaker trips at loads well below its rating. Do not tape a breaker in the on position or install a higher-amperage breaker as a fix. Both approaches remove the protection the breaker is designed to provide. Our electricians diagnose the root cause and fix the problem properly the first time, rather than simply resetting the breaker.

A GFCI (Ground Fault Circuit Interrupter) outlet detects when electrical current flows along an unintended path and cuts power within milliseconds. Under NEC Section 210.8, GFCI protection is required in kitchens, bathrooms, garages, all outdoor locations, crawl spaces, unfinished basements, and near pools, hot tubs, and wet bars. Many older Tempe homes are missing GFCI outlets in several of these locations, which is both a code compliance issue and a safety risk.

A GFCI outlet protects the outlet itself and any standard outlets wired downstream from it on the same circuit. If an outlet in your kitchen, bathroom, or garage stops working, check a nearby GFCI outlet for a tripped reset button before calling us. If resetting the GFCI does not restore power, or if the GFCI trips again immediately, call our team.

First, check whether the outage affects your whole neighborhood or only your home. If your neighbors have power and you do not, the problem is in your service entrance, main panel, or the utility connection to your home. Call us and also report the issue to APS or SRP. If the outage is widespread, check the APS or SRP outage map for the estimated restoration time.

Turn off or unplug sensitive electronics and appliances before power is restored. The surge when utility power comes back on is one of the most common causes of appliance damage after a monsoon storm. A whole-house surge protector handles this automatically. If you have a Generac standby generator, it should start automatically within 10 seconds of detecting the outage. If it does not start, check the generator’s status panel and call us for service. In Tempe’s summer heat, do not wait out a long outage without a plan. If you do not have a generator and the outage extends beyond a few hours, move to a cool location.

A brief, slight flicker when a large motor starts, like an AC compressor, is normal and usually harmless. If the flickering is pronounced, frequent, or happens on multiple circuits, it points to a more serious issue: an undersized service, a loose connection at the panel or meter base, a failing breaker, or insufficient wire gauge on the circuit. In Tempe homes where the electrical system is already under heavy summer load, pronounced flickering deserves an inspection. Loose connections generate heat over time and create a fire risk if left unaddressed.

We know that Tempe’s climate puts real demands on your electrical system. Summer temperatures regularly top 110°F, pushing air conditioners, pools, and appliances to their limits. Monsoon season brings lightning, power surges, and outages that damage electronics and disrupt your home. Older homes in Tempe face a different set of electrical issues: outdated wiring, undersized panels, and aging infrastructure that was never designed to carry today’s electrical loads.
