FAQs

Why should I install a standby generator for my Huntsville home?

North Alabama sits in the Tennessee Valley tornado corridor, so power outages from severe weather, fallen limbs, and ice storms are common. A permanently installed generator automatically restores electricity within seconds, keeping HVAC systems, refrigeration, medical equipment, and internet running—critical in Huntsville’s hot, humid summers and occasional winter freezes. It also protects sensitive electronics from power-loss surges, prevents frozen pipes, and preserves home security systems, adding real estate value and peace of mind.

What size generator do I need to back up my entire house?

Sizing depends on the loads you want to run. A typical 2,500–3,000-sq-ft Huntsville home usually needs a 14–22 kW unit to cover major circuits (HVAC, refrigerator, lights, and a few outlets). If you want whole-house coverage—including dual-stage heat pumps, electric water heaters, and well pumps—25–38 kW may be required. We perform a free on-site load calculation, measuring starting (surge) and running watts of each appliance, local utility voltage, and gas-line capacity to recommend the properly sized generator and automatic transfer switch.

How much does a whole-house generator cost in Huntsville?

Turn-key pricing (equipment, concrete pad, labor, gas plumbing, permits, and startup) typically ranges from $8,500 for a 14 kW air-cooled model to $18,000+ for a 38 kW liquid-cooled system. Factors include electrical service size (100/200/400 amp), trenching distance to the gas meter or propane tank, local code upgrades, and optional load-management modules. We provide firm, written quotes after the site visit and offer financing plans up to 120 months through TVA EnergyRight partners.

Do I need permits or inspections for a generator installation in Huntsville or Madison County?

Yes. The City of Huntsville and Madison County require an electrical permit, a mechanical (gas) permit, and an electrical inspection before activation. If you are in Limestone or Morgan counties, similar requirements apply. Our licensed electricians and master gas fitters handle all paperwork, coordinate with Huntsville Utilities or Joe Wheeler EMC for meter pulls, and schedule the final inspection, ensuring your installation meets NEC 2023, local amendments, and TVA interconnection standards.

Which fuel source is better for my generator—natural gas or propane?

Most Huntsville homeowners choose natural gas because it offers unlimited runtime, ties into existing Huntsville Utilities gas service, and eliminates onsite fuel storage. If natural gas is unavailable in your subdivision, propane is a reliable alternative; a 250- to 500-gallon tank can power a 22 kW generator for 5–9 days of continuous runtime. We size gas piping, regulators, and tanks to maintain proper BTU delivery and ensure code-compliant setbacks from windows, crawl-space vents, and ignition sources.

How often does my generator need maintenance, and do you offer service plans?

Manufacturers recommend service every 6 months or after 100 run hours. Routine maintenance includes oil and filter changes, valve clearance checks (for air-cooled units), battery load testing, firmware updates, and a full exercise under load. Our Huntsville GeneratorCare plans start at $259 per year, covering two visits, 24/7 remote monitoring, priority storm response, and a 5-year parts-and-labor warranty extension. Regular maintenance ensures the unit starts when TVA grid power fails and keeps your manufacturer warranty valid.
