"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 questions, answered by experts

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
