"Ahmad was a true professional!! He came in and looked at what I wanted done and was able to start and complete the light/ceiling fan repositioning in the same visit. He was kind and very informative and made my electrical installation safe (which it wasn’t before). Thank you for your kindness and for explaining everything to me so now I know what to look for and what questions to ask in the future!!!"

"Superb experience! Greg provided an education along with the estimate and each team that has come out to place the generator, wire the generator, and complete the install (after the propane gas hook up) has been terrific -- professional, courteous, wearing masks per CDC and Virginia guidelines. The installation, (generator, transfer switch, panel and status lights) are all finished to a T and look great, too!"

"James came out to price install of a box to plug in my portable generator. After we started talking and me asking questions James was able to give me an outstanding price on a whole house Generac generator with panel upgrade and included a whole house surge protector. They ran into additional costs with running the gas line but James kept to his word and honored the original price! The crew were professional and proficient in their work! Marcie was outstanding with communication and explaining any questions I had! I would definitely recommend this company and would use J&M for any future electrical needs!"

"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."

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
