FAQs
What types of generators do you service and install in Ooltewah?
Our technicians are trained to work on a full range of residential and light-commercial generators, including air-cooled and liquid-cooled standby units, portable gasoline generators, and PTO-driven units for farms. We are factory-certified for leading brands such as Generac, Kohler, Briggs & Stratton, and Cummins, but we can diagnose and repair virtually any make or model. Whether you need a new whole-house standby system or a tune-up on an existing portable generator, we have the expertise and parts inventory to get the job done quickly.
How do I determine the right size standby generator for my home or business?
Proper sizing depends on the total wattage of the critical circuits you want backed up. During our free on-site assessment, we calculate the starting and running loads of appliances like HVAC units, refrigerators, medical equipment, and computer servers. We also factor in future expansion, fuel availability (natural gas, propane, or diesel), and local voltage requirements. Using load-calculation software and manufacturer guidelines, we recommend the smallest generator that will comfortably handle your needs, preventing overloads while keeping upfront and operating costs reasonable.
What is involved in a professional generator installation?
A turnkey installation includes: 1. Site evaluation and permitting with Hamilton County Building Inspection. 2. Concrete pad or composite base preparation to meet code-required clearance and flood-plain rules. 3. Electrical integration with an automatic transfer switch (ATS) sized for your service panel. 4. Fuel line sizing and connection—coordinated with your gas utility or propane supplier. 5. Final wiring, load testing, and voltage/frequency calibration. 6. County inspection and manufacturer start-up certification, which activates your warranty. The average residential install in Ooltewah takes one to two days once permits and materials are ready.
How often should my generator be serviced and what does maintenance include?
Standby generators should receive professional maintenance every 6–12 months or after 100–150 run hours, whichever comes first. A standard service visit includes oil and filter change, spark-plug replacement, valve clearance check, battery load test, air filter inspection, firmware updates, and a 20-minute load bank run to ensure the unit reaches operating temperature under simulated demand. For commercial sites with mission-critical loads, we offer quarterly inspections and remote monitoring packages that alert us to faults in real time.
Do I need a permit or inspection for generator installation in Ooltewah?
Yes. Hamilton County requires an electrical permit and, if fuel lines are added or modified, a mechanical/gas permit as well. We handle all paperwork, pay the permit fees, and schedule the required rough-in and final inspections. This ensures your installation complies with National Electrical Code (NEC) Article 702, local zoning setback rules, and manufacturer warranty terms. Skipping permits can result in fines and may void your homeowner’s insurance coverage after a claim.
How quickly can you respond to generator emergencies, especially during storms or power outages?
We provide 24/7 emergency service to the greater Ooltewah area, including Collegedale, Apison, and East Brainerd. Calls received during widespread outages are triaged, with priority given to medical facilities, essential businesses, and households with critical medical equipment. Our technicians carry common parts—plugs, filters, control boards, and voltage regulators—on their service trucks, allowing us to resolve 80% of no-start or fault issues on the first visit. Typical on-site response time during normal conditions is under 90 minutes; during severe weather events it may extend to 3–4 hours, but we’ll keep you updated via text or phone.
