Florida Keys Roots Since 2009
Check Electric has worked the Florida Keys since 2009, with crews dispatched out of Key West and a new Summerland Key headquarters opening soon. Our team covers residential, commercial, and generator service across the island chain.
Local Team, Local Response
Crews run from Key West to Key Largo with no third-party dispatch and no mainland subcontracting. Generator repair calls route through the local team that already knows island logistics, ferry windows on Little Palm, and the gated-community access that mainland shops can't navigate.
Problems We Solve
Four Failure Modes We See on Standby Units
Generator repair searches usually start after a failed self-test, a no-start during an outage, or a missed service interval. Salt air, storm season, and the gap between install and actual readiness create real failure modes on standby units that look fine until they don't.
Salt-Air Corrosion Wrecks Standby Generators
Coastal exposure degrades enclosures, terminals, and fuel system components on units that pass weekly self-tests. Our generator repair services catch corrosion before it kills the start sequence.
- Annual corrosion inspection
- Battery and fuel system checks
- Post-storm diagnostics
Missed Annual Service Means Outage Risk
Skipping oil, filter, and battery work is the most common reason standby units fail when they're needed. Worn belts and normal wear degrade performance between service intervals. Generac maintenance guidance sets the baseline.
- Manufacturer service intervals vary by model
- Battery charge checks
- Oil and filter replacement
Post-Storm Failures, Hidden Damage
Hurricane debris, water intrusion, and load surges leave damage that isn't visible until the next outage. Post-storm diagnostics catch it before you rely on the unit again.
- Enclosure and fuel system inspection
- Electrical load test
- Fast response across the islands
Permits and Process, No Surprises
Most repairs don't need a permit, but replacement or relocation often does, and the Key West permit requirements include site plan, specs, and platform details.

Your Options
Four Ways We Service It
Annual Service Contract
For owners who want pre-season readiness without the scheduling scramble. Includes oil, filter, and battery service on a Generac annual or 200-hour interval, corrosion inspection, fuel system check, and priority response when an outage hits. Most contract holders schedule service before hurricane season opens in June.
Break-Fix Repair
For owners with a unit that won't start, won't transfer, or has thrown a fault code. One-time diagnostics across all generator makes, root-cause troubleshooting on controls, transfer switch, fuel delivery, and battery, then a clear repair quote before any work proceeds. No service contract required.
Post-Storm Diagnostic and Repair
For owners after a hurricane or named storm event, especially when the unit ran for extended hours under load. Full system check covering enclosure damage, fuel and oil contamination, battery condition, electrical load test, and corrosion review. Dispatched on a response priority based on damage severity.
Replacement and Upgrade Path
For owners with units past economical repair, undersized for current load, or facing parts obsolescence on older models. Includes replacement consultation, sizing review against actual panel load and requirements, permit navigation, and full install coordination once you select a new generator.

FAQs
Generator Repair Questions
- How often should a standby generator be serviced in the Florida Keys?
- Generac specifies annual or 200-hour oil and filter intervals on its standby units, and coastal owners should hold that schedule strictly. Salt exposure in the Keys accelerates corrosion on terminals, enclosures, and fuel system components even when the unit passes weekly self-tests, so routine maintenance catches what the self-test misses. Check Electric handles oil, filter, battery, corrosion inspection, and fuel system review on every annual visit.
- What does generator annual service include?
- Oil and filter replacement, battery load testing, spark plugs, fuel system check, corrosion review on terminals and enclosure, and debris cleaning around the unit. Our annual visit also covers a full self-test verification, transfer switch operation under load, and a written summary of any wear items that should be tracked for the next visit. On Keys properties the service adds a coastal corrosion walk-through that mainland service contracts typically skip. Most annual visits wrap in a single trip.
- Should I repair or replace my standby generator?
- Repair makes sense when the unit is under 12 years old, parts are still supported, and corrosion is surface-level rather than structural. Replacement makes sense when controls are obsolete, the enclosure is compromised, or repair costs exceed roughly half of replacement. A written recommendation on every diagnostic visit, not a sales pitch. Check Electric services all makes, so there's no incentive to push replacement when repair is the right call in the Florida Keys.
- Is salt air hard on standby generators in the Florida Keys?
- Yes. Generac notes that owners within 100 miles of the coast face long-term corrosion risk, and the entire Florida Keys sits well inside that zone. Salt air attacks terminals, control boards, fuel system fittings, and enclosure fasteners on a faster timeline than inland units. Annual inspection by a licensed electrical contractor familiar with coastal failure patterns catches early corrosion before it interrupts the start sequence. This is why annual service in the Keys is not optional maintenance.
- Can any electrician repair a Generac generator?
- Any licensed electrician can troubleshoot basic faults, but warranty work and certain control board repairs require an Authorized Dealer. Check Electric is a Generac Authorized Dealer with full sales, service, and installation authorization. Our team also services Kohler, Cummins, Briggs, and other standby makes, which matters when your unit was installed by a shop that no longer serves the Keys. All-makes diagnostic capability is rare in the local market, where most dealers service only what they sell.
- Do generator repairs require a permit in Key West?
- Repairs to an existing unit in its current location typically do not require a permit. Replacement, relocation, or new install does require a permit, with site plan, equipment specs, installation guidelines, and platform details. Check Electric handles permit submittal and inspection coordination as part of any replacement project, which is why local contractor selection matters in the Keys.
- What happens if my generator still self-tests but has not been serviced?
- A passing self-test does not replace annual maintenance. The self-test runs the unit briefly without load, which won't reveal weak batteries, degraded oil, fuel system contamination, or corrosion on load-side terminals. Most no-start failures during an actual outage happen on units that had been self-testing fine for months. Annual service in the Florida Keys catches the hidden wear that self-tests miss, especially battery degradation, which is the single most common cause of standby generator failure.
- What should be checked after a storm before I rely on my generator again?
- Enclosure damage, water intrusion, battery condition, fuel quality, control board status, and a full electrical load test. Self-test alone is not enough after a named storm. If your unit ran for extended hours under load during the outage, oil and filter should be inspected even if the annual interval hasn't hit. Post-storm diagnostics catch debris damage and salt intrusion that surface weeks later as start failures. Look for warning signs like unusual noise or fuel odors. Post-storm diagnostics are run by Generac factory-trained technicians.
