"He is extremely attentive to your needs . What he says will happen , does! He keeps all appointments and thoroughly explains what he plans to do. He is one of the most reliable, ethical , conscience businessman I have ever dealt with. I have recommended him to friends . He actually went out of his way to help Ill friends deal with their generator problems even though he had not installed it. He made arrangements for someone to fix the generator when he was not able. Highly recommended !"

"I was very impressed with David's responsiveness and every member of his crew was a pleasure. They completely removed the kitchen floor (and several layers of subfloor) in my 100+ year-old home, made repairs to floor joists and installed new flooring that looks beautiful. It was an evolving project and I appreciated the team's flexibility and speed with which they completed the project."

"It was a pleasure to deal with this company. They are extremely knowledgeable in designing an electrical charging station in what was a difficult i situation. My breaker panel and garage were on opposite sides of my home. A solution was given at a reasonable price. I could not be happier. All work was done professionally with great attention to detail. If you are in need of electrical services, donâ t look any further. They are without a doubt, the best."

"Posted a job for a boiler replacement on homeadvisor on thursday and got a call in less than half an hour. Ron, one of the owners, said he could come take a look on saturday morning. I got a quote on monday. I decided to hire them on friday. Jeremy the boiler specialist and other co owner came by the the next day to take a few more pictures and check on a few other things. The boiler we decided on was a special order and took a few weeks to arrive. It came in on a monday and was installed by thursday. They started on thursday morning with a two man crew. Around lunch the Jeremy came by to see how things were going. Around 2pm an other two guys showed up to help. At about 3:30 the co owner and boiler specialist came by to oversee the final part of the install and operational testing. I was originally told it would be a two day install. They didn't just replace the boiler, they replaced the expansion tank, dual zone control box, etc. They worked until around 7pm to get it all done in one day. They bled all the radiators in the house and made sure they were heating properly. They took all the old parts with them and left no trash behind. Everybody from this company was extremely professional. They arrived within five minutes of the time they said they would be at my house. Nobody could beat the quote they gave me for the install. Any questions I had were responded to in 30 minutes or less. The install looks amazing so much shiny copper pipe. Cawiamca gave me a 3 year warranty where they will take care of all the labor and parts if anything goes wrong. This was by far the best experience I have ever had with a company coming to my house to do something.They performed consistently above my expectations. They will be the first people I call if I need any more work done on my heating system. I highly recommend Cawiamca."

"William Burden is the third generation owner of WBLightningRods and his company has been in business since 1950. He is very courteous, professional, was on time, and has a very good crew. William was present for the entire installation. We chose the copper system. We are glad for the peace of mind a lightning rod system will provide."

Generator Install questions, answered by experts

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.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

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.
