FAQs
Why should I consider a standby generator for my Ooltewah home or business?
Ooltewah experiences severe thunderstorms, winter ice events, and occasional tornado–related outages. A permanently installed standby generator turns on automatically within seconds of a utility failure, keeping HVAC systems, refrigeration, medical equipment, and critical electronics running. It protects your property from frozen pipes, spoiled food, and lost productivity while giving you peace of mind during Tennessee Valley Authority (TVA) grid interruptions.
What size generator do I need?
Correct sizing depends on the total wattage of the circuits or appliances you want to back up. A typical 2,500–3,500 sq ft residence in Ooltewah usually requires a 14–22 kW air-cooled unit to run essentials (HVAC, well pump, kitchen, lights). Larger homes, commercial buildings, or those with three-phase service may need a 30–60 kW liquid-cooled model. We provide a free on-site load analysis to calculate starting and running watts, fuel type, and transfer-switch requirements so you get a generator that is neither under- nor over-sized.
How long does the installation process take from start to finish?
Once you approve the proposal, most residential installs are completed in one to two days on site. Before that, we handle permitting with Hamilton County Building Inspection, coordinate natural-gas or propane upgrades, and schedule the final electrical inspection. Including permit approvals, the entire process typically spans two to three weeks, though propane tank placement or utility work can extend the timeline slightly.
Do I need permits or inspections in Ooltewah?
Yes. Hamilton County requires an electrical permit for the generator, and a mechanical/gas permit if we tie into a natural-gas line. After installation, a county inspector verifies compliance with NEC 70, local amendments, and clearance rules. Our team pulls all permits, provides one-line diagrams, and meets the inspector on site so you do not have to manage any paperwork.
How often does a standby generator need maintenance, and do you service what you install?
Manufacturers recommend maintenance every 6–12 months or after 100–200 running hours. Service includes an oil and filter change, spark-plug inspection, valve adjustment, battery test, and a simulated outage load test. We offer annual maintenance plans that include remote monitoring, priority emergency service, and discounted parts to keep your warranty intact and your generator ready when the next outage hits.
Will installing a generator increase my property value or affect insurance rates?
Real-estate studies show that properly installed standby generators recoup 50–70 % of their cost at resale and can make a listing stand out in the competitive Ooltewah market. Many insurers classify standby generators as a loss-mitigation device and may offer a modest premium discount for whole-house coverage. Ask your carrier; we can supply installation certificates and serial numbers to support any discount request.
