Summer in Tallahassee doesn’t ease your building into the heat — it slams the door. July and August average highs are roughly 91°F, and afternoon heat indexes regularly exceed 100°F. For a business, that means your HVAC, refrigeration, and equipment all run harder, longer, and simultaneously. Across Florida, air conditioning in homes and businesses is the single biggest driver of electricity use — the state’s residential sector alone accounts for more than half of all electricity consumed, the largest share of any state in the country.

Here’s the part most owners don’t think about until it’s too late: the statewide grid hits its peak between 2 p.m. and 6 p.m. on the hottest days, exactly when your building is also pulling its hardest. If your electrical system was sized years ago — before you added that second walk-in cooler, those extra workstations, or a new rooftop AC unit — summer peak is when the weak link finally shows itself.

As a commercial electrician serving Tallahassee and the Big Bend, GT Electric sees the same preventable failures every July. Below are five warning signs your business needs an electrical upgrade before the summer peak hits — not during the outage that shuts you down.

1. Your Breakers Trip Repeatedly (Especially in the Afternoon)

A breaker that trips once is doing its job. A breaker that trips every afternoon is telling you the circuit is carrying more load than it was built to handle. When your AC compressor, kitchen equipment, or production line all draw at once on a 95°F afternoon, an overloaded circuit generates heat — and heat is what turns an inconvenience into a fire hazard.

This isn’t a small-business footnote. Electrical distribution, lighting, and power-transfer equipment is the leading category of equipment involved in fires at industrial properties, and wiring-related issues alone account for roughly 12% of those fires, according to the National Fire Protection Association (NFPA). Most non-home electrical fires start between 8 a.m. and 8 p.m., while your people are inside working.

What an upgrade looks like: Rebalancing loads across circuits, adding dedicated circuits for high-draw equipment, or upgrading the panel to handle your real-world demand instead of the demand you had five years ago.

2. Lights Flicker or Dim When Equipment Kicks On

If the lights dip every time the AC compressor or a large motor starts, your service is struggling to deliver steady voltage under load. That voltage drop isn’t just annoying — it shortens the life of motors, compressors, and sensitive electronics, and it’s a classic symptom of an electrical service that’s undersized for the building’s current needs.

In a Tallahassee summer, that strain is constant. When cooling demand is the largest single use of electricity in commercial buildings and your equipment cycles all day, an undersized service never gets a break. The flicker you ignore in June becomes the compressor failure you pay for in August.

What an upgrade looks like: Evaluating your service capacity and, where needed, upgrading the service entrance, transformer feed, or panel to keep voltage stable even when everything runs at once.

3. Warm Panels, Discolored Outlets, or a Faint Burning Smell

Walk over to your electrical panel and put the back of your hand near it. It should be cool. Warm cover plates, outlets that are hot to the touch, scorch marks, or a faint “fishy” or burning odor are signs of loose connections and arcing — the conditions that precede an electrical fire.

These warning signs deserve urgent attention. Over the last decade, more than 20,000 U.S. workers have been injured in workplace electrical incidents, and there were over 1,300 workplace fatalities involving electricity between 2011 and 2022 (OSHA data compiled by the Electrical Safety Foundation International). The vast majority of workplace electrical fires trace back to electrical or mechanical failures, overloaded equipment, or combustible material too close to a heat source — all of which intensify under summer load conditions.

What an upgrade looks like: A licensed commercial electrician performs an infrared/thermal inspection of your panel and connections, tightens or replaces failing terminations, and corrects the underlying overload before it ignites.

4. You’re Running an Outdated or Undersized Panel

Many Tallahassee commercial buildings are still running on panels and service sizes specified for a different era of business. Fuse boxes, certain discontinued panel brands, and service sizes that can’t keep up with modern HVAC and equipment loads are common — and they quietly cap how much your business can grow.

Electricity accounts for about 60% of the energy used in U.S. commercial buildings, and cooling is the largest summer draw. If your panel is at or near capacity today, there is no headroom for that next rooftop unit, EV charger, or kitchen expansion — and no margin on the hottest day of the year. An aging panel is also harder to service, more likely to have brittle insulation and loose lugs, and more prone to the heat-related failures that cluster in summer.

What an upgrade looks like: A panel or service upgrade sized to your actual and planned load — giving you both safety margin and room to expand without redoing the work in two years.

5. You Have No Backup Power or Surge Protection

Summer in North Florida means afternoon thunderstorms, lightning, and hurricane season — layered on top of a grid already running near its limit. Florida is the third-largest electricity consumer in the nation and routinely sets new peak-demand records during heat waves, with major utilities pushing toward 30,000 megawatts on the worst days. When the grid is stressed, and a storm rolls through, commercial buildings are exactly where outages bite hardest: lost refrigeration, downed point-of-sale systems, idle production, and customers turned away.

A whole-building surge protection device shields your equipment from voltage spikes caused by lightning strikes and grid switching. A properly sized standby generator keeps you open when the power is out for hours. As an authorized Kohler and Generac dealer, GT Electric specs, installs, and maintains commercial backup generators built for Tallahassee businesses that can’t afford to go dark.

What an upgrade looks like: Whole-building surge protection at the panel plus a commercial standby generator sized to carry your critical loads — refrigeration, HVAC, security, and operations — through an outage.

Don’t Wait for the Outage to Make the Decision

Each of these five signs worsens under load, and load peaks in July and August. The cheapest time to fix an electrical problem is before it fails — not during the afternoon your breakers finally give out, and you’re closed for business with a freezer full of spoiling product.

A commercial electrical assessment is straightforward: a licensed GT Electric technician evaluates your panel, service capacity, connections, and backup readiness, then gives you a clear, prioritized plan — what’s urgent, what can wait, and what it costs. No pressure, no surprises.

Schedule your commercial electrical assessment before the summer peak. Call GT Electric at (850) 655-0868 or request service online. We serve commercial and residential customers across Tallahassee and the Big Bend from our office at 3154 Eliza Rd, Tallahassee, FL 32308.

Frequently Asked Questions

How do I know if my business needs an electrical panel upgrade?

The clearest signs are breakers that trip repeatedly, lights that dim when equipment starts, warm or discolored panels and outlets, a burning smell, or a panel that’s already at capacity with no room for new equipment. A commercial electrician can confirm with a load evaluation and thermal inspection.

Why is summer the most important time to address commercial electrical issues?

Cooling is the single largest electrical load in Florida buildings, and the grid peaks between 2 and 6 p.m. on hot afternoons. Your system runs at its absolute hardest in July and August, so any weakness — an overloaded circuit, an undersized service, a loose connection — is most likely to fail then.

How long does a commercial electrical upgrade take?

It depends on the scope. Rebalancing circuits or adding surge protection can often be done in a day, while a full service or panel upgrade is typically scheduled over one or more days with minimal disruption. GT Electric provides a timeline and a quote up front after the assessment.

Does GT Electric install commercial backup generators?

Yes. GT Electric is an authorized Kohler and Generac dealer and installs and maintains commercial standby generators sized to keep your critical operations running through outages and storms.
