Will a 22kW generator power my entire house?

A 22kW air-cooled generator can power most 2,000–3,500 sq ft DFW homes completely, including central AC, refrigerator, lights, outlets, and well pump. For homes larger than 4,000 sq ft, multiple HVAC zones, or electric water heaters, we typically recommend a 24kW–26kW unit or a 38kW+ liquid-cooled generator.

Can I run my generator on propane or natural gas?

Yes. Most residential standby generators are dual-fuel capable and can run on either natural gas or propane. Natural gas is preferred for convenience — no tank refills needed. Propane is ideal for rural properties without gas service. The right fuel is recommended based on your availability and preference.

How loud is a standby generator?

Generac Guardian air-cooled generators operate at approximately 66–68 dB at 23 feet — similar to a lawn mower heard from across the yard. Kohler liquid-cooled models run quieter at 62–65 dB. QuietSource and commercial enclosures can reduce noise to 55–60 dB. We position generators to minimize noise impact on patios, bedrooms, and neighboring properties.

Do I need a permit to install a generator in Dallas or Fort Worth?

Yes. All standby generator installations require an electrical permit from your city. Natural gas connections require a plumbing permit and gas line inspection. Clements Electric handles all permitting, utility coordination, and inspection scheduling as part of the installation service. HOA additional approval requirements are assisted with as needed.

Why Standby Generators Matter in Dallas–Fort Worth

North Texas faces unique power reliability challenges that make standby generators a smart investment:

Ice storms and freezing rain — tree limbs and power lines collapse under ice weight, causing multi-day outages

Summer heat waves and ERCOT grid strain — rolling blackouts during peak demand leave homes without air conditioning when it is 105°F outside

Spring derechos and severe thunderstorms — straight-line winds of 60–80 mph topple poles and transformers

Tornadoes and hail storms — direct strikes and debris damage destroy above-ground electrical infrastructure

Planned maintenance and substation upgrades — utilities schedule multi-hour outages for grid modernization

Medical equipment and home health needs — oxygen concentrators, CPAP machines, and refrigerated medications require uninterrupted power

Home offices and remote work — power outages now mean lost wages and missed deadlines

Security systems and sump pumps — outages disable alarms and allow basement flooding

Generator Maintenance and Repair Services

A standby generator that sits unused for months will fail when you need it most. Clements Electric offers comprehensive generator maintenance to keep your system reliable:

Annual maintenance — oil and filter change, spark plug inspection, air filter replacement, coolant check, battery load test, and exercise cycle verification

Bi-annual maintenance for commercial generators — more frequent service for high-duty-cycle units

Remote monitoring setup and troubleshooting — Mobile Link, OnCue Plus, and third-party monitoring integration

Battery replacement — generator batteries typically last 3–5 years. We test and replace before failure.

Fuel system service — propane regulator checks, natural gas pressure testing, and fuel line inspection

Transfer switch maintenance — contact cleaning, controller firmware updates, and load testing

Emergency generator repair — 24/7 response for generators that fail to start, overload, or produce unstable power

Generator relocation — move an existing generator to a new pad or new property
