"Had Stagecoach RV in Peru work on RV generator, called me said circuit board caught fire and found one on an online bidding store for 909$ and some change took home to put in the pole barn. Spring comes to get RV out change all fluids fire generator up to cool down RV with ac, doesn't work. Call stagecoach RV and tells me guy who did generator quit to get a job with insurance, so I'm screwed out of 900 and my one year warranty? He said I can give you his number. (screwed) checked Angie s List and Huston Electric came up? Knew they did commercial and residential wiring did not know they worked on Rv generators, so I left to search, 10 minutes later they call me saying yes we see you inquired about work need on Rv generator. I told him all I knew and we were leaving for outer banks on Friday (this is Monday on phone) guy says bring it by tomorrow. I said I'm on a time crunch to load for a trip can I bring it this evening, he asked a guy there how late in the shop he said he would wait. I dropped off Monday evening, got call 10:15 am Tuesday we got you all fixed up someone been in circuit board area and had loose pin connector and loose connection at 30 amp breaker and straightened up wiring on board it was a mess, also looks like someone put in new voltage regulator and never adjusted it was only getting 107volts, adjusted it and all is good. I went to pick up and he said I had to look up the schematic for wiring and it brought up the whole manual so I printed it off for you and put it in a plastic binder. $285.00 out the door worked great on the trip no issues and if I need generator service again it will be Huston Electric in Lafayette"

Generator Install FAQs, answered by experts

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.
