"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."

"Had original part of our 1965 built house rewired and grounded and a new bath fan installed and vented. Jerry and Joey were personable, , knowledgeable, hardworking, and kept us informed on what they were doing. We regained the use of several electrical outlets and a non-working light switch and peace of mind in having electrical safe and grounded.. They had to navigate a very low crawl space to do some of the work. All for such a reasonable price that I wish we had done this years ago! Thank you HomeAdvisor for helping us find Peco!"

Generator Install questions, answered by experts

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.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

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

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

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.
