Editorial Review
Our Take on ONYX Electric
The review count stands out. Nearly 900 reviews at 4.9 on the Google profile as of September 30, 2026 is the sort of record that comes from steady residential volume over more than a decade, not a marketing push. We would push hardest on the three-year parts-and-labour warranty and the two-hour arrival window, both claims the company makes about itself, because if they hold up as written they are genuinely better than the Tampa norm.
Best forhomeowners across Tampa Bay who want panel, generator and EV charger work from a licensed residential specialist
What We Like
- 4.9 rating from 897 reviews on its Google Business Profile, read September 30, 2026
- Florida electrical contractor licence EC13011854 published on its own website
- Hours listed as 24 hours a day, seven days a week, with emergency calls advertised at any hour
- Wide service map covering Hillsborough, Pinellas and Pasco counties
- Broad residential range, from outlet repairs to panels, rewiring, generators and EV chargers
- Trading since 2013 according to its own site, with a stated three-year parts and labour warranty
Things to Consider
- Presents itself as a residential electrician, so large commercial or industrial work is likely a poor fit
- Warranty, insurance, bonding and arrival-window claims come from the company's own website and are worth confirming in writing
- No pricing published, and after-hours call-out rates are not stated
- The Google listing and the website show different phone numbers, so confirm which line reaches dispatch

Company Background
About ONYX Electric
Tampa homes come in waves of construction, and each wave brings its own electrical headaches. Bungalows in Seminole Heights and South Tampa with cloth-insulated branch circuits and two-prong receptacles. Mid-century ranch houses in Town 'N' Country where the original 100-amp service was never meant to run a modern air handler plus a pool pump. Nineties and 2000s stock in Westchase, Cheval and New Tampa, generally sound but now getting car chargers, hot tubs and whole-home generators bolted onto panels that were sized for none of that. Onyx electric works across all of it, from Pinellas beach towns through Hillsborough and up into Pasco, and the service list reflects that spread rather than one narrow speciality.
Day to day, the work divides into repairs and installations. On the repair side that means tracing dead circuits, replacing failed breakers, sorting out tripping GFCIs, and diagnosing the kind of intermittent faults that only show up when the humidity climbs. Installation covers panel upgrades and replacements, rewiring, lighting and ceiling fans, outlets and switches, appliance circuits, generator and transfer switch work, pool and spa electrics, and EV charger installation. Electrical safety inspections are offered as a standalone service, which matters more in Florida than people expect, both for insurance underwriting on older houses and before a sale.
Who it suits: homeowners who would rather call one contractor for the small stuff and the large, and who want someone reachable outside business hours. The published hours are 24 hours a day, seven days a week, and the company states that emergency calls are answered at any hour. In a region where afternoon storms and summer lightning knock out circuits with real regularity, that availability has practical value. Who it suits less: anyone chasing large commercial fit-outs, industrial service work or ground-up multifamily electrical. The company presents itself as a residential electrician, and the marketing leans that way throughout.
The credibility markers here are worth setting out plainly. The Google Business Profile shows 4.9 from 897 reviews, read on September 30, 2026, and volume at that level usually means a crew doing a high number of modest jobs rather than a handful of big ones. The website lists Florida electrical contractor licence EC13011854 and says the business has operated since 2013. It also claims insured and bonded status, a three-year warranty covering both parts and labour, and a two-hour arrival window on scheduled appointments. Those are the company's own statements, not independently verified here, so ask for the warranty terms in writing and check what voids it. Warranty length is a genuine differentiator in this trade, where one year is common, so it is worth understanding whether it applies to the fixture the homeowner supplied or only to parts the contractor provided.
A few things to raise on the phone before booking. Ask whether an unincorporated Hillsborough County or City of Tampa permit is needed for your job, who pulls it, and whether the inspection fee sits inside the quote; panel changes and service upgrades almost always need one, and a contractor who waves that away is a contractor to avoid. Ask how the call-out is priced after hours, since round-the-clock coverage and standard daytime rates rarely coexist. For a panel replacement, ask whether the utility disconnect and reconnect is coordinated by the electrician or left to you. For EV chargers, ask about load calculations rather than just outlet placement, because a 48-amp charger on an older 150-amp service often needs a load management device instead of a service upgrade. And for coastal properties in Pinellas, ask about corrosion-rated equipment, since salt air chews through standard panel guts faster than most owners anticipate.
Compared with the alternatives around Tampa Bay, onyx electric sits between the one-van independent and the large multi-trade franchise. Independents can be cheaper and are often excellent, but they rarely answer the phone at 2am and rarely offer multi-year warranties. The big branded operations offer the coverage but usually price with membership plans and option sheets. A mid-sized residential specialist with a wide service map and a long review history is a reasonable middle path, particularly for homeowners in the northwest Hillsborough and Pasco corridor, where the Dupont Circle base and the listed service zone overlap most closely. As always, get the scope and the price in writing, and confirm the licence number against the state database before work begins.

ONYX Electric FAQs
Is ONYX Electric licensed in Florida?
Its own website publishes Florida electrical contractor licence EC13011854, and describes the business as insured and bonded. That is the company's own statement rather than something verified here, so check the number against the state licensing database before work starts. It takes a minute and is standard practice for panel or service work.
Do they really answer the phone at night?
The published hours are 24 hours a day, seven days a week, and the company advertises emergency electrical service at any hour. What is not stated anywhere public is the after-hours rate. Ask on the call whether there is a night, weekend or holiday premium and how the diagnostic fee is handled, because round-the-clock coverage is almost always priced differently to a Tuesday morning visit.
What areas around Tampa do they cover?
Hillsborough, Pinellas and Pasco counties, per its website service map. Named areas include South Tampa, Westchase, Town 'N' Country, Carrollwood, Northdale, Lutz, New Tampa and Temple Terrace, plus Clearwater, Dunedin, Palm Harbor, Largo and Tarpon Springs on the Pinellas side and New Port Richey, Trinity, Odessa and Land O Lakes in Pasco. The business address is on Dupont Circle in northwest Tampa.
How good are the reviews?
The Google Business Profile showed 4.9 from 897 reviews when read on September 30, 2026. That is a high rating on a large sample, which generally reflects consistent small-to-mid residential jobs over years rather than a short burst of feedback. Reading a handful of the most recent ones is still worth doing, since they tend to describe current scheduling and communication.
Will I need a permit for a panel upgrade?
Almost certainly, yes. Panel replacements and service upgrades in the City of Tampa and unincorporated Hillsborough County generally require a permit and an inspection, and the utility has to disconnect and reconnect the service. Ask who pulls the permit, whether the fee is inside the quote, and who coordinates with the power company, then get the answer in writing.
What does the three-year warranty cover?
The company states it covers both parts and labour for three years. Since that is longer than the one-year term many electricians offer, it is worth asking for the written terms: whether it applies to fixtures or equipment you supplied yourself, what counts as a covered failure, and whether storm or surge damage is excluded. Florida lightning activity makes that last point more than academic.
Can they install an EV charger on an older Tampa house?
Often yes, but it depends on the existing service capacity. EV charger installation is on their service list. On a 1970s or 1980s home with a 100 or 150-amp service, a full-output charger may need either a service upgrade or a load management device, so ask for a load calculation as part of the quote rather than just a price for running the circuit.
