Answers to Common Questions
View All FAQsWhat are the top reasons a Generac generator won't start?
Top reasons we see Generac standby units not start are: weak battery, blown fuses, closed gas supply or low gas pressure, dirty air filter or fouled spark plugs, and outdated firmware. An ATS setting or fault can also prevent automatic starts. Our GenConnect maintenance checks battery health, gas connections, filters and plugs, ATS operation, and software updates using Generac-certified parts and technicians in Houston and Conroe.
Quick checks:
- Make sure the ATS is in AUTO.
- Ensure the gas valve is open.

The top reasons a standby generator won’t start are battery or starter power issues, fuel or air supply problems, and control-system safety lockouts. The most common cause is a weak or drained battery after long idle periods. Other frequent culprits include stale or shut-off fuel, clogged filters or plugs from overdue maintenance, and the unit left out of Auto after prior testing or service. Our licensed electricians often see these patterns pick up around storm cycles in the Woodforest area.
Look for these quick checks:
- Battery terminals corroded or loose; charger or battery breaker off.
- Fuel valve closed, propane tank low, or gas line pressure off.
- Air filter heavily clogged or spark plugs fouled.
- Control not in Auto, or a low-oil/over-temp shutdown needing reset.
If you smell gas, hear abnormal electrical noise, or the unit trips repeatedly on restart, stop and schedule a professional inspection. <br/> Updated: 2026-03-14 <br/> Need help in Woodforest, TX? Call (713) 812-7070 or book online.

Change the oil at least once every two years, following Generac’s recommendation. Abacus’s GenConnect maintenance includes an oil and filter change with Generac-approved synthetic oil during each full-service visit. Our licensed, Generac-certified technicians also check fuses, battery health, and ATS operation as part of service. If you want more frequent care, Abacus offers annual maintenance with 24/7 remote monitoring for Houston-area homes.

Standby generator repair cost is confirmed after an on-site diagnosis by a licensed technician, because parts, labor, and warranty coverage set the final price. Most repair bills come from replacing wear items or correcting fuel or transfer switch issues rather than major engine work. Abacus provides Generac-certified service and handles warranty support through our Independent Authorized Service Dealer status, and our GenConnect plan includes 24/7 monitoring and scheduled maintenance to reduce surprise breakdowns. We also service homeowners in and around New Caney with trained, in-house electricians and certified Generac technicians.
What most affects price and next steps:
- Diagnostic and testing time, including ATS checks and fault codes
- Parts needed (battery, sensors, control board, regulators) using genuine Generac parts for warranty compliance
- Warranty path: repairs must be done by an Independent Authorized Servicing Dealer; Abacus files claims and GenConnect members have zero deductible under warranty
- Scope decision: repeated failures, heavy corrosion, or obsolete models may favor replacement over repair
Schedule a diagnostic visit promptly if the unit will not start, shows an alarm, or you smell gas. <br/> Updated: 2026-03-29 <br/> Need help in New Caney, TX? Call (713) 812-7070 or book online.

Home standby generator installation cost depends on your home and the system you choose, and we offer free in-home estimates and second opinions. Price is driven by generator size (common 8–22 kW), fuel type (natural gas or propane), Automatic Transfer Switch options, and any electrical upgrades found during our pre-install inspection. A mounting pad is included with our Generac whole-home systems, and many installed systems list a 5-year limited warranty. We install and integrate so power restores automatically within seconds.

You will likely need a permit and inspection for a whole‑house generator, but exact requirements depend on your city and utility. Our licensed electricians provide turnkey, code‑compliant installations and will confirm local permitting steps during your free in‑home estimate. We complete a pre‑install electrical inspection and load calculation, install and test the Automatic Transfer Switch, and set up natural gas or propane fuel. In Houston and nearby areas, we also support warranty documentation through certified Generac maintenance as an Independent Authorized Service Dealer (IASD).
