Home Backup Generator Installation in Cheyenne, WY

Generator sizing depends on which circuits and appliances you want to power during an outage. For essential circuit coverage (furnace, refrigerator, sump pump, some lights, and a few outlets), a 10kW to 14kW generator is typically sufficient. For full-house backup including central air conditioning and all circuits, most Cheyenne homes need 20kW to 26kW. We perform a detailed load calculation during your free assessment that identifies the exact generator size your home requires based on your specific equipment, HVAC system, and backup priorities.

A complete whole-house generator installation including the generator unit, automatic transfer switch, concrete pad, electrical connections, gas line work, permits, and inspections typically ranges from several thousand dollars for essential-circuit coverage to significantly more for full-house backup with premium features. The exact cost depends on generator size, fuel type, site conditions, and any panel or service upgrades needed. We provide detailed, itemized proposals during your free assessment so you know exactly what is included before committing. Financing options are available for qualified homeowners.

If your home has a natural gas connection from Black Hills Energy, natural gas is typically the best choice because it provides an unlimited fuel supply without the need for tank refills. The fuel cost is generally lower than propane as well. If your home is outside the natural gas service area, propane is your option. We help you size the propane tank based on expected generator runtime. A 500-gallon tank can typically run a whole-house generator for several days depending on load. Both fuel types provide reliable performance in Cheyenne’s cold winters when properly installed with cold-weather kits.

A natural gas generator can run indefinitely as long as the gas supply is maintained, which it typically is since natural gas pipelines are underground and not affected by most weather events that cause power outages. Propane generators run until the tank is empty, with runtime depending on tank size and load. A 500-gallon propane tank at fifty percent load on a 20kW generator provides approximately five to seven days of continuous runtime. All generators require periodic oil level checks during extended runs, and most modern units have low-oil shutdown protection to prevent engine damage.

Modern whole-house generators from Generac and Kohler operate at approximately 60 to 70 decibels at a distance of 23 feet, which is comparable to a normal conversation. Older or larger generators can be louder. We select generator models and installation locations that meet city noise ordinances and minimize impact on your family and neighbors. The sound-attenuated enclosures on current models are significantly quieter than generators from even five years ago. Placement strategy also matters, and we position units away from bedroom windows and neighboring properties whenever possible.

Yes. Standby generators require annual maintenance including oil and filter changes, air filter replacement, spark plug inspection, battery testing, and a full load test. Most modern generators run a brief automatic exercise cycle weekly to keep the engine lubricated and the battery charged, which ensures the unit is ready when needed. We provide maintenance guidance during your installation walkthrough and can recommend local service providers for ongoing maintenance. Following the manufacturer’s maintenance schedule is essential for warranty coverage and long-term reliability, especially in Cheyenne’s demanding climate.

Yes. Generator installations in Cheyenne require both an electrical permit and a building permit. There are also setback requirements that dictate minimum distances from property lines, windows, doors, and fresh air intakes. We handle all permitting including application submissions, inspection scheduling, and compliance verification. NEC code and local regulations also require specific clearances around the generator for ventilation and service access. Our site assessment identifies the optimal location that meets all code requirements while providing convenient access for maintenance.
