"I needed a Tesla charger installed in my garage. They showed up to the house quickly, and were very knowledgeable on what to do and what i needed. They installed it within an hour, with very quality parts, and were very neat and tidy about it too. No issues since install! I definitely would consider them again in the future!"

"Ideal experience with this company! They contacted me and came out to make the bid the same day I contacted them. They were super flexible and worked to accommodate my schedule. I needed to wait until my EV charger arrived from the manufacturer. They came out the day after it arrived, installed the unit in under two hours, and it's been working flawlessly ever since. Don't let their name fool you--John's Waterproofing is expert at electrical work! I will use them again."

"I hired Charles to install an EV charger in our garage. He promptly provided an estimate and recommended installing a new, larger electrical panel to replace our old panel which was almost 40 years old and did not have space to add the EV charger circuit. I also asked him to install a generator inlet to the panel so that the EV battery could be used to power parts of the house in case of a power outage. Charles got the job done and had to rearrange some circuits so that the EV can power the most important portions of the house during a power outage. Overall, I am very happy with the quality and the efficiency of the work."

"The plumber arrived on time. Assessed the problems , made a bid and then went ahead and fixed the problems that same day. He made the bid , went out to buy the parts and returned to complete the installation . However I ended up paying over $425/ hour!!!! I thought it would be more difficult to fix the [problem but it only took the actual work about 5 hours total. I want to stress that my job was completed adequately. However, now I feel " taken" for the job provided."

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
