FAQs
What types of generators do you offer for homes and businesses in Huntsville?
We carry a full line of standby, portable, and industrial-grade generators from trusted manufacturers such as Generac, Kohler, and Cummins. Residential clients often choose air-cooled standby units ranging from 10 kW to 26 kW, while commercial and industrial customers can select liquid-cooled natural-gas or diesel systems from 30 kW up to 2 MW. We size every generator based on your specific load requirements, fuel availability, and future expansion plans.
How does a standby generator automatically restore power during an outage?
Each standby system includes an automatic transfer switch (ATS) that continuously monitors incoming utility voltage. When it detects a power loss, the ATS signals the generator to start, typically within 10–15 seconds. Once the generator reaches proper speed and voltage, the ATS disconnects your building from the grid and routes generator power to your electrical panel. When Huntsville Utilities restores service, the ATS transfers the load back to the grid and shuts the generator down after a cool-down cycle.
What permits or inspections are required for generator installation in Huntsville and Madison County?
The City of Huntsville and Madison County require an electrical permit for any permanent generator installation. For natural-gas units, a plumbing/gas permit is also needed. Our licensed electricians handle all permitting, schedule inspections with the local building department, and ensure compliance with the 2020 NEC, local amendments, and utility interconnection guidelines. We also coordinate with Huntsville Utilities for any necessary meter upgrades.
How often should my generator be serviced, and what does maintenance include?
Manufacturers recommend preventive maintenance every 6 months or after 200 hours of run time, whichever comes first. A standard service visit includes oil and filter changes, air filter replacement, spark-plug inspection, battery load testing, coolant level checks (for liquid-cooled units), valve adjustments if required, and a full operational test under load. We offer tiered maintenance plans with 24/7 monitoring so you’re never without support during North Alabama’s storm season.
Can a generator power my entire home, including HVAC, or should I choose a partial-load setup?
That depends on your home’s total running load and budget. A whole-house system is sized to run all critical circuits plus high-demand appliances like HVAC, water heaters, and ovens. In Huntsville, the average 2,400 sq ft home with a 4-ton heat pump typically needs a 22 kW to 24 kW generator for full coverage. A partial-load or managed-load setup uses a smaller unit (14 kW-18 kW) and smart load-shedding modules to prioritize essentials such as lights, refrigerators, and medical equipment. We perform a free load analysis to help you decide.
What factors affect the total cost of installing a standby generator in Huntsville?
Pricing is influenced by generator size and fuel type, distance to the electrical panel and gas meter, pad or concrete work, transfer-switch rating, and permitting fees. For a typical 20 kW natural-gas unit, turnkey installation in the Huntsville area ranges from $9,500 to $13,500. Larger commercial diesel systems can exceed $30,000. We provide upfront, itemized quotes and financing options such as 0% APR for 18 months to make reliable backup power more accessible.
