Electrical Panel Upgrades in Largo
Largo has a large stock of 1960s to 1980s single-story block homes and many manufactured home communities. Original panels from that era, including Federal Pacific and Zinsco, are common, and insurers frequently flag them during 4-point inspections. Manufactured homes have their own electrical requirements, so we check the service type and park rules before we quote.
Largo is also home to many retirees adding equipment like heat pumps, mini splits or standby generators, which usually requires more capacity than an original 100-amp panel can provide.
Panel upgrade questions from Largo homeowners
Can you upgrade a panel in a Largo manufactured home?
Yes, in most cases. We confirm the service setup and any park requirements first.
Is a panel replacement covered by insurance?
Usually not, but replacing a flagged panel is often what keeps a policy active.
How much notice do you need?
We can usually inspect within a few days and schedule the replacement after permitting.

Recent Panel Work Near Largo
Our technicians completed 222 jobs in Largo in the last 12 months. These recent Pinellas County calls show why we test before we recommend a new panel.
- A loose connection, not a new panel. In Clearwater (33762) this month, a homeowner had been told they needed a new panel. Sasha measured 14 volts on one leg at the main breaker, found bus bar discoloration from a loose connection, tightened it and restored power.
- Burn marks on the bus bar. In Pinellas Park, Sasha found a burn mark on a panel bus bar during a backup power consultation and explained when it should be monitored and when the panel should be replaced.
- Utility-side problems. In St. Petersburg (33712), Nick traced a no-cool call to missing 240-volt service at the meter base and sent the homeowner to the utility instead of selling AC parts that would not fix it.
