We at Dial One Johnson have served North Texas since 1965, and we treat backup power the way we treat every system: sized correctly, installed to code, and proven before we leave.
Thinking About Backup Power? You Are Not Alone
The moment most DFW homeowners start pricing a generator is the day after an outage. The common triggers:
- A storm outage that outlasted the food in the refrigerator
- A household member who depends on powered medical equipment
- A home office that cannot afford a dark day
- An existing generator that failed its one job when the power went out
A standby generator answers all four, but only if it is sized, fueled, and maintained correctly.
Common Generator Problems We Solve Across DFW
Undersized Units That Stall Under Real Load. A generator sized by guesswork drops the AC the moment the well pump kicks in. We calculate your home actual starting and running loads before recommending a unit.
Generators That Fail When Finally Needed. Standby units that sit untested for months develop dead batteries, stale fuel issues, and failed transfer switches. Scheduled exercise cycles and annual maintenance are what make a generator a guarantee instead of a gamble.
Improper Fuel and Gas Connections. A whole home generator draws far more gas than any appliance in the house. Our licensed plumbers size and install the gas supply correctly, because an undersized line starves the unit exactly when demand peaks.
Aging Units Past Reliable Service. Like any engine, a generator has a service life. We repair what can be trusted and tell you plainly when it cannot.

Why Backup Power Is a Serious Question in North Texas
Dallas Fort Worth sits in one of the most active severe weather corridors in the country. The National Weather Service Fort Worth office tracks the region spring supercell season, straight-line wind events, summer heat-driven grid strain, and the occasional ice storm, and every one of those hazards takes down power lines somewhere in the metroplex most years.
The outages that matter are not the twenty-minute flickers. They are the multi-day events: an ice storm coating lines in February, a derecho snapping poles in May, a strained grid shedding load in a July heat wave. In each case, the homes that stay lit, cooled, and connected are the ones that answered the backup power question before the weather asked it.
A standby generator is only as reliable as its weakest detail: the load calculation that sized it, the gas line that feeds it, the transfer switch that engages it, and the maintenance schedule that keeps all three honest. Those details are exactly where we focus.
We size against your real loads, install gas and electrical connections to code with permits pulled, commission the unit under load, and put it on a maintenance schedule that means the next outage is an inconvenience for the neighborhood and a non-event for your house.

Why DFW Families Choose Dial One Johnson for Backup Power
Sized by Calculation, Not Catalog. Your home real starting and running loads decide the unit, so the system holds when everything kicks on at once.
Licensed Where It Counts. Gas connections by licensed plumbers (Texas plumbing license 41416), as state law requires, with permits and inspections handled on every installation.
Proven Before Handover. Every installation ends with a commissioning test under load and a walkthrough of the transfer switch, exercise schedule, and maintenance plan.
Maintained for the Long Wait. Annual maintenance and exercise verification, because a generator job is to sit ready for years and then work perfectly on minute one.

Frequently Asked Questions About Generator Services in DFW
It depends on what must stay powered: whole home coverage including central AC demands far more capacity than essentials only. We calculate your starting and running loads and show you options at each coverage level, priced side by side.
A portable covers a few circuits and requires you to be home, fuel it, and run cords safely. A standby unit starts itself within seconds of an outage, powers what it was sized for, and refuels from your gas line. For medical equipment, home offices, or summer outages, standby is the reliable answer.
Annual professional service at minimum, plus the unit own weekly exercise cycle, which we verify is actually running. Batteries, oil, and transfer switch function are the usual failure points in units that skip it.
Often not without upgrading. Whole home units draw more gas than any household appliance, and an undersized line starves the engine under load. We size and, when needed, upgrade the supply line as part of every installation.
Yes. Generator installations involve gas, electrical, and placement requirements that vary by city across the metroplex. We pull the permits, install to code, and coordinate the inspections.
