"Ryan did a great job installing a bathroom light/fan and venting it through the attic to the exterior of the house, replacing 3, bathroom outlets that didn’t meet code and installing floor outlets in my living room. He and his assistant were professional and efficient and therefore a pleasure to work with. I plan to have him do some additional work in the future."

"I originally hired Services & More to cut my grass. But...one thing led to another. As I also had an issue with one one my windows. The trim was rotted and water was getting into the wall causing damage, along with that, we desperately needed to replace our shingles. My husband and I wanted vinyl siding done. Adam, was very helpful with the whole process. Before I knew it everything we needed done had gotten done, and then some. What I liked most about this company was he never pushed or tried to sell us on any services. We just happened to ask. Once again, Adam took care of what we wanted to do and more, because we asked, including our garden beds. When they did the siding, they replaced ply wood in the areas that needed it, and also repaired the foundation, in certain spots. Adam also did the interior of our wall, where that window was. ALL VERY reasonable in price! Considering that they did quite a lot. They are my go to guys!! I've hired them for life! Highly recommend!!"

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.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
