A typical residential generator installation takes between 6 to 10 hours, depending on the fuel source and site conditions—natural gas units generally complete in 6 to 8 hours, while propane systems requiring tank installation extend to 8 to 10 hours.
The installation timeline reflects the complexity of integrating multiple interconnected systems. When Blackmon Plumbing arrives at your property, our team is prepared with generators, transfer switches, electrical components, and gas fittings expertise. This approach eliminates the parts delays that commonly stretch other installations across multiple days or require callbacks. We arrive prepared to complete the job as efficiently as possible, in many cases wrapping up the same day.
The installation process itself involves several critical stages. First, our licensed technicians assess your home's electrical panel and gas infrastructure, determining the optimal generator placement—typically a concrete pad in the yard with clear access to your main electrical panel and gas line. We then install the automatic transfer switch, a device that detects power loss and seamlessly transfers your home's electrical load to the generator within milliseconds. This component requires precise electrical connections to meet National Electrical Code standards and local permitting requirements.
For natural gas installations, we connect the generator to your existing gas line, which significantly reduces installation time since no fuel storage infrastructure is required. Propane systems demand additional work: we coordinate tank placement, install pressure regulators, run copper tubing to the generator, and ensure all connections meet safety codes. This additional complexity accounts for the longer timeframe.
Blackmon Plumbing holds an MPL-38162 license and maintains authorization as both a Generac and Noritz dealer, certifications that reflect our commitment to manufacturer standards and ongoing technical training. Our 19 years in business have taught us that proper permitting before installation day is essential—we coordinate with your local municipality to schedule inspections and utility connection approvals, preventing delays that would otherwise extend your project timeline.
Site-specific factors influence the actual duration. Homes with outdated electrical panels may require upgrades before transfer switch installation. Properties with distant gas lines or complex terrain might require extended trenching. However, our pre-installation consultation identifies these variables upfront, allowing us to provide accurate time estimates and schedule accordingly.
Weather conditions rarely impact installation since most work occurs outdoors and isn't weather-dependent, though extreme conditions may affect concrete curing if a new pad is required. We typically schedule installations Monday through Friday to coordinate with permit inspections and utility company representatives who verify gas connections and electrical work.
