What size generator do I need for my house? (kW calculator guidance)

Generator sizing starts with understanding what you want to power and the “starting surge” of motor-driven appliances. In most homes, major loads like central air conditioners, heat pumps, well pumps, sump pumps, refrigerators, and furnaces require extra power for a few seconds at startup. A practical kW calculator approach is to list your essential circuits (refrigeration, lighting, outlets, internet, furnace blower, sump pump) and then decide whether you want to add comfort loads like central A/C, electric range, or whole-home coverage. Potts Electric can perform a load assessment in Fenton, MO and recommend a generator size that balances comfort, safety, and cost.

As a rule of thumb, many “essentials only” backup plans land in the 7–14 kW range, while whole-home standby generators commonly fall between 16–26 kW depending on HVAC and electric appliances. The best way to avoid overbuying—or worse, undersizing—is to evaluate your panel, the nameplate ratings of your major equipment, and your actual usage goals during an outage. For a more complete home electrical plan, you may also want to review our electrical panel upgrade services if your panel capacity or condition limits generator integration. Call Potts Electric to schedule a sizing consultation and get a clear recommendation with options.

Whole house generator vs portable generator: which is better for home backup power?

A whole house standby generator is permanently installed, connected to your fuel source (often natural gas or propane), and paired with an automatic transfer switch that starts the generator and switches power automatically when the utility fails. This option is ideal if you want seamless backup power, have frequent outages, travel often, or need reliable support for critical loads like medical equipment or a sump pump. Standby generators also integrate cleanly with your electrical panel, reducing the risks associated with cords and temporary setups. In Fenton neighborhoods where outages can last hours or longer, standby power offers the most convenient and dependable protection.

A portable generator is typically less expensive upfront and can be a good fit if you only need to run a few items intermittently. However, it requires manual setup, safe placement away from the home, fuel storage, and a plan to connect power properly to avoid backfeeding and carbon monoxide hazards. Many homeowners choose a portable generator paired with a professionally installed transfer switch or generator inlet to power selected circuits safely. If you’re weighing options, Potts Electric can help you compare total costs, convenience, fuel logistics, and the number of circuits you want powered—and we can install either solution with safety as the priority.

Transfer switches & automatic transfer switches (ATS): what you need and how it works

Do I need a transfer switch for a portable generator and how is it installed? If you want to power household circuits from a portable generator, a transfer switch (or an interlock kit where permitted and appropriate) is the safe, code-compliant way to do it. A transfer switch prevents dangerous backfeeding that can energize utility lines and damage appliances when power returns. Installation typically includes mounting the transfer switch near your main panel, adding a generator inlet (so you can plug in outside), and moving selected circuits to the transfer switch so you can run them during an outage. Potts Electric will help you decide which circuits matter most—refrigerator, sump pump, furnace, select lighting and outlets—then label and test the system for straightforward use.

How does an automatic transfer switch (ATS) work with a standby generator? An ATS constantly monitors incoming utility power; when it senses an outage, it signals the standby generator to start and stabilize, then automatically transfers the home’s load to generator power. When utility power is restored and stable, the ATS transfers the load back and signals the generator to shut down after a cool-down period. This automation is what makes standby systems so convenient and consistent—especially during overnight outages or when you’re away from home. If you’re planning a standby system, Potts Electric can also coordinate related work such as whole-home surge protection to help shield electronics from switching events and utility fluctuations.

Standby generator runtime, fuel choice, and powering central air conditioning

How long can a standby generator run continuously during an outage? Most residential standby generators are designed for extended operation and can run continuously for long periods as long as fuel supply and maintenance needs are met. Natural gas standby generators are often the most “set-and-forget” because the fuel is delivered through the gas line, avoiding refueling logistics during a multi-day outage. Propane standby generators can also run for long durations, but runtime depends on tank size and load—higher electrical demand consumes fuel faster. Potts Electric can help you estimate realistic runtime based on generator size, home load, and fuel availability in Fenton, MO.

What fuel type is best for home generators: natural gas vs propane vs diesel? Natural gas is popular for standby generators in St. Louis County and Jefferson County areas where gas service is available because it offers continuous supply and convenient operation. Propane is an excellent alternative for homes without natural gas, and it stores well, making it dependable when gasoline supplies are limited during regional storms. Diesel is more common in commercial applications and can be efficient, but it typically involves on-site fuel storage, additional maintenance considerations, and higher equipment cost for many residential setups. We’ll review your property’s fuel access, space, local requirements, and outage patterns to recommend a practical solution.

Can a generator power central air conditioning and what size is required? Yes, a generator can power central A/C, but sizing must account for the compressor’s starting surge, which is often the biggest electrical demand in a home. Many homeowners who want A/C during an outage choose a larger standby generator or add load management that allows the generator to handle the A/C without sacrificing other essentials. In some cases, installing a soft starter on the A/C system reduces startup demand and can allow a smaller generator to do the job. Potts Electric can evaluate your HVAC nameplate ratings and recommend a generator size and configuration that supports comfort without overloading the system.

Standby generator installation cost breakdown, maintenance checklist, and noise reduction

Standby generator installation cost breakdown: equipment, labor, permits, and transfer switch. The total cost of a standby generator project is made up of several key components, and understanding them helps you plan confidently. Equipment includes the generator unit, the automatic transfer switch (ATS), the mounting pad or base, and any load management modules if needed. Labor typically covers electrical work at the main panel, routing conduit and wiring, setting and securing the generator, and testing the full start/transfer/restore sequence under load. Permits and inspections may be required in the Fenton, MO area depending on the scope, and they ensure your installation meets code for safety and reliability.

Standby generator maintenance checklist: how often to service and what’s included? Like any engine-driven system, standby generators perform best with routine service. Common maintenance includes oil and filter changes, air filter inspection, spark plug checks (where applicable), battery testing/replacement, coolant checks on liquid-cooled models, and a full system test to confirm proper ATS operation and startup reliability. Many manufacturers recommend servicing annually or after a set number of run hours, and more frequent attention may be appropriate if the generator runs for extended outages. Potts Electric can set you up with a maintenance schedule and help you stay ready before storm season arrives in Fenton.

How loud are standby generators (dB levels) and how to reduce generator noise? Most residential standby generators operate roughly in the 60–75 dB range at a measured distance, depending on brand, size, and installation location. Proper placement is one of the best ways to reduce perceived noise—positioning the unit away from bedroom windows, using manufacturer-approved sound attenuation features, and following required clearance rules. Landscaping elements and fencing can help redirect sound, but they must not restrict airflow or violate clearance requirements. If generator noise is a concern, Potts Electric will review placement options and recommend solutions that respect both performance and neighborhood comfort.
