"Mr. Green TRULY puts the customer first! He installed a whole house generator for me last August and called to check on us 6 months later because bad weather is coming. Brought me a key and showed me (again) how to add oil. I had several estimates and he beat other prices by several thousand $ AND he installed a bigger generator! I will definitely hire him again and recommend him to every one!! 5 star service *****!!"

"SUMMARY: HIGH QUALITY WORK WITH LARGE PRICETAG. Corley plumber arrived on time. Their plumber was polite and offered several options for the repair. The repair was completed correctly and in a timely manner. Work area was cleaned after plumbing work was completed. No problems with the repair since it was completed which was several years ago. In short, I would give them FIVE STARS FOR THE QUALITY OF THEIR WORK. I would hire them again in an EMERGENCY (which is why I hired them for this work; the usual plumbers I use were unavailable), but NOT for non-emergency work. My reason for not wanting to use them for routine work is that their prices were OUTRAGEOUS and I'm not a miser (this is why I removed one star in my rating). The few replacement parts needed would have been nominal cost at a plumbing supply store. That means their labor was $200+/hr for installing compression fit connections which is even easier and quicker than gluing PVC pipes together (no heavy lifting; nothing complicated; easy access to pipes). I've had other plumbing jobs that were too big for me to do. I've found competent plumbers that do a great job (quality like Corley's) for half the price if you are willing to wait a day or two. Lesson: Instant gratification has a high price tag. FYI: They will charge for the cost estimate if you don't have them do the repair."

Generator Install questions, answered by experts

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.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

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.

Costs depend on generator type, labor, and additional wiring or transfer switch requirements.
