"We replaced the original roof on our house. I expressed my concerns about re-installation of the lightening rods to my roofer. We have had at least three direct hits since they were originally installed in 2013. My roofer called William who was very helpful. William offered to come out an make sure everything was 100% after re-installation. He came the day after I called and I'm glad he did. While the reinstall was the best he had seen (his words) there were issues after 5 year and 3 strikes that needed addressed. He fixed those and now I have a new roof and I am certain the lightening rods will work as intended. Highly recommend this company."

"Home and changes are fine, but footer leaks and had to install sump pump and dehumidifier with full encap in crawl space. Also, builder didn’t use full dimensional lumber, but used ijoists without fire protection. Carried plastic gas line through the crawl space wall. Used 5x5 wooden piers to hold up my home instead of building block piers. Had to install jack posts to cover for this."

RC WATT builds on the Vision with the Mission: Provide clients with "Reliable Convenient Power" using onsite power systems. Today's homeowner seeks our permanently installed, backup offerings, because they want the benefits of having power restored automatically, in seconds, when millions of other people in the U.S., lose power each week. Today's home is more than the family hub - it is for many the work place, and for others - a place to convalesce. Home office and medical equipment need electricity. While electricity was a luxury a hundred years ago; today electricity is essential to our way of life. Centrally produced power, certainly a great value, comes with the limitations of reliability inherit with miles of wires and other infrastructure. Please carefully consider the question: When is a good time to lose power? Utility power outages are unpredictable. Given the affordability of today's onsite power systems, the quality solutions we provide enable our clients to enjoy the best of both models.

"From start to finish RCWatt was professional, knowledgeable, friendly, and efficient. There was no high sales pressure. RCWatt arrived on time, assessed my individual situation, inspected the inside and outside of my house to determine the best site for installation, and presented options for me based on what we discussed. He explained every aspect in detail and answered each and every question to my satisfaction. I approved the options to update my 35 year old electrical service and panel at a discount as well as the addition of full house surge protection. The generator was installed within 30 days of my acceptance. The technicians were very professional and friendly and stayed on the job that day until it was finished! The areas they worked within were as clean when they left as when they arrived. Matt was very knowledgeable and gave great instructions on the generator's use following it's installation. I highly recommend RCWatt and would choose this firm again."

FAQs for generator install projects in Mount Morris, PA

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:

Portable generators with 1kW–7.5kW capacity: $500–$2,000
Partial generators with 9kW–20kW capacity: $2,000–$6,300
Whole-house generators with 22kW–48kW: $5,000–$18,000

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

Refrigerator: 600 watts
Large dehumidifier: 700 watts
Large window air conditioner: 1,400 watts
Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running.

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.

The value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:

Experience frequent or prolonged power outages
Work from home
Store a lot of cold food
Have a sump pump
Have a pump for well water
Use electronic medical devices
Live in a climate requiring heating or cooling
