"Yep, Indaspec is a five start company. They were responsive and professional. The system we got has boosted our 2003 system and cost 1/5th the price. It will pay itself off in 3 years, possibly less. They were efficient in the installation - took about 1.2 days. The connection between our system and the app on our phones is super easy and now my husband and I have been high- fiving each other once we find out how much the new system is producing. Get the solar, Guys! This company is a gem! The office manager is a sweetheart and the bidding process was easy. The installer was a man of few words for me (I didn't really know anything about the tech part), but took time to speak to my curious and informed contractor husband. He was patient and explained everything so that my husband felt satisfied that he was doing right by our beloved and somewhat coddled home."

"JP Services installed a Moen Flo water leak detector. The original pipe was a little short, so he extended it to install the device. The job was done well, but he had to fix a small leak he caused and left some residue from his blowtorch. Overall very worth the price."

Generator Install questions, answered by experts

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. 

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

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.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.
