FAQs
What types of generators do you install and service in the Rockford area?
We install and service a full range of generators, including standby whole-home units (typically 7 kW–48 kW), commercial three-phase generators up to 500 kW, and portable inverter models for smaller or temporary power needs. Our technicians are certified to work on leading brands such as Generac, Cummins, Kohler, Briggs & Stratton, and CAT, ensuring Rockford homeowners and businesses get the right fit for their load requirements and budget.
How do I determine the correct generator size for my home or business?
Proper sizing starts with a load analysis. We calculate the running and startup (surge) wattage of the appliances, HVAC systems, and critical circuits you want backed up. For homes, this usually ranges from 7 kW (essential circuits) to 22 kW (whole-home). For businesses, we evaluate three-phase equipment, peak demand, and mission-critical processes. After the assessment, we recommend a generator with at least a 15 % safety margin to handle future load additions and prevent overload shutdowns.
Do I need a permit to install a standby generator in Rockford?
Yes. The City of Rockford and Winnebago County require electrical and, in most cases, plumbing or gas permits for standby generator installations. As a licensed electrical contractor, we handle the permitting process, including submitting load calculations, site plans, setback requirements, and scheduling the final inspection so you remain fully code-compliant.
How often does a generator need maintenance, and what does it include?
For residential standby units, manufacturers recommend maintenance every 6–12 months or after 200 hours of run time, whichever comes first. Service includes oil and filter changes, spark-plug replacement, battery inspection, air-filter cleaning, firmware updates, and a full system test under load. Commercial generators often follow quarterly or annual schedules based on NFPA 110 guidelines. We offer preventive maintenance agreements that keep you covered and maintain warranty validity.
Can a standby generator power my entire home during a Rockford winter outage?
Yes, as long as the generator is properly sized and paired with an automatic transfer switch (ATS). We account for high-demand winter loads—furnace blower motors, sump pumps, space heaters, and even electric water heaters. A whole-home generator (18 kW–26 kW for most houses) can seamlessly power every circuit, ensuring your heating system, refrigerator, and well pump stay online even in sub-zero conditions.
What is the average installation timeline and cost for a residential standby generator?
From initial consultation to final inspection, the average timeline is 2–3 weeks. The actual on-site installation takes 1–2 days, including pad placement, electrical wiring, gas line connection, and ATS mounting. In Rockford, turnkey costs (equipment, labor, permits) generally range from $8,000 for a 10 kW essential-circuit system to $15,000+ for a 22 kW whole-home solution. We provide transparent quotes, financing options, and utility rebate guidance to keep the project within your budget.
