Answers to Common Questions
View All FAQsWhat are the top reasons a Generac generator won't start?
There isn’t one single “top reason.” In our experience, no‑start issues usually trace to fuel supply, electrical connections, or control settings specific to your installation. A licensed technician should diagnose on site and verify operation after service.
Quick checks:
- If your unit uses household gas, make sure the home’s gas supply is available.
- If the power is out, the system should auto‑start; if it doesn’t, stop and call us.
- Schedule maintenance if it’s overdue; we service and repair standby generators. We offer 24‑hour electricians and same‑day appointments if you call before 10 AM in Dallas–Fort Worth. <br/>

Change the oil in your standby generator on the schedule the manufacturer specifies for your model and usage. Milestone offers generator maintenance and can perform oil changes during service. Our electrical maintenance plans include a yearly inspection, and your technician will confirm the correct interval and set reminders. After installation, we also verify operation so your system is ready when power goes out. We service the Dallas–Fort Worth area, including Dallas and Fort Worth.

Standby generator repair cost is confirmed after an on‑site diagnostic because parts, labor time, and brand requirements determine the price. The biggest swing is whether the visit finds a simple maintenance issue or a failed component that requires replacement.
We regularly service North Texas homes and see that costs track the complexity of the fix rather than the generator size. Same‑day or next‑day appointments and 24/7 emergency service are available.
What most affects price and decisions:
- Component type: battery, regulator, controller, engine, or alternator repairs vary widely.
- Access and labor: fuel, wiring, or transfer‑switch work takes longer than routine adjustments.
- Warranty status: Milestone‑installed units include a 5‑year parts and labor warranty, which can offset repair costs.
- Replace vs. repair cues: repeated major failures or severe engine/alternator damage often favor replacement; minor control or fuel issues usually merit repair.
- Treat as urgent: gas odor, smoke, or sparking around the unit.
Schedule a diagnostic so a licensed technician can load‑test the system and give a written repair estimate before work begins. <br/> Updated: 2026-04-02 <br/> Need help in Garland, TX? Call (214) 717-6708 or book online.

The cost to install a home standby generator is confirmed after an on-site assessment and varies with generator size, fuel setup, electrical work, and permitting. The biggest driver is the generator’s capacity and any gas line or meter changes needed to supply it. Most installations take 1–2 days, with about 4 hours of planned power downtime, and city permits typically add about 4 weeks lead time. Our team routinely manages permitting and inspections across the Garland area.
Key factors that drive price:
- Generator capacity (kW) and Kohler model selection
- Gas line or fuel supply work to meet demand
- Electrical scope: automatic transfer switch, panel/meter upgrades, surge protection
- Installation complexity: pad, placement distance, and wiring run length
All installs include a 5-year parts and labor warranty, plus the first year of service; a 5-year maintenance plan is available. Current offer: $500 off Generator Installation. Schedule an in-home assessment to receive a firm, written price. <br/> Updated: 2026-03-13 <br/> Need help in Garland, TX? Call (214) 717-6708 or book online.

You can handle simple visual checks, but full standby generator maintenance and repairs are best left to a licensed technician. Milestone sells, installs, maintains, and repairs whole‑home generators, and we commission the system to ensure it works. We offer 24‑hour electricians and same‑day appointments if you call before 10 AM. You can request a complimentary quote, and qualifying installations advertise a 5‑year warranty.
Quick checks you can do:
- Keep the area around the generator clear.
- Look for damage or leaks and listen for unusual noise.
- Note any warning lights and call a pro.
