Generator Services FAQs
We install a wide range of generators for homes, commercial buildings, and industrial sites across Houston and surrounding areas. Our primary offerings include home standby generators, portable units, and large commercial-grade systems from trusted brands like Kohler, Duromax, and Generac. Each installation is tailored to the property, factoring in load requirements, automation preferences, and future power demands.
Whether you’re seeking a fully integrated backup system with auto-start capability or a more affordable, manual solution for emergencies, we’ll walk you through your options and help you select the right generator for your building, budget, and energy priorities.
Standby generators should be serviced at least once a year, regardless of how often they’re used. Regular maintenance typically includes oil and filter changes, spark plug inspection, battery testing, and running a full system check to catch potential issues before they become emergencies. In high-use areas or storm seasons, semi-annual servicing may be recommended.
Staying current on generator maintenance not only helps avoid unexpected outages, it also preserves your manufacturer’s warranty. Colwell Electric offers preventative service plans to make it easy to stay protected and powered all year long.
Yes. Every standby generator installation we perform includes an automatic transfer switch (ATS) as part of the setup. The ATS monitors your utility line in real-time and automatically switches to generator power when an outage occurs, usually within 10 seconds. This eliminates the need for manual startup or intervention.
We use transfer switches that are compatible with each generator brand we install and ensure everything is properly calibrated for your load size, building code, and electrical layout. Our installations are clean, compliant, and designed for reliability when it matters most.
Absolutely. We specialize in generator replacements, whether you’re upgrading due to age, capacity issues, or a change in fuel source. We begin each project with a full assessment of your current setup—including load calculations and transfer switch compatibility—before recommending the best-fit replacement unit.
Our team handles safe removal of the old system, installation of the new generator, any necessary rewiring or panel updates, and final system testing. We’ll also make sure your new generator is registered with the manufacturer and that you understand how it works before we leave.
Yes. Financing is available for most generator installation projects, and we’ll walk you through your options during the consultation. Depending on your budget and the size of your system, we can connect you with flexible payment plans that break your project into manageable monthly costs.
We believe no one should have to go without power protection because of upfront cost concerns. Our team will help you find a solution that ensures your home or business stays powered without delay.
