"I needed a generator transfer switch installed before the storm. Mark with A+ Electric came out within the hour and gave me a very reasonable quote. He wired my house for a generator the following day!! Thoroughly impressed!! He was very nice and ensured I knew how to operate everything in case of an outage. His work was very neat and professional. I will definitely use him again."

"Paul tackled reconfiguring our old steam shower motor as well as installation of extra outlets. He also ran a dedicated line for a future sump pump. The steam shower work was a real challenge but Paul refused to give up. He worked until it was he successful. For over a year we have enjoyed a like new steam shower thatâ s actually 36 years old. We were so pleased with his performance, his price, and his punctuality, weâ ve hired him for other electrical work. We most highly recommend Paul without any reservations. We consider him â our electricianâ !"

"I started my Angi project to do 6 fan replacements + 1 new fan install where a lighting fixture is hanging. The person who came in to do the consult and look around quoted me very high price. When I shared that their cost is higher than the standard Lowe's fan installation cost he was appreciative of me sharing the information and said that he will consult with his manager to get us a better price. In the end, the price quote I got was slightly higher than Lowe's. If you are looking for handyman type of work or anything small, Angi is not a platform to find the person. That is what I have learned from my first 2 projects at Angi. I took 2 stars away because Angi platform did not create a good match and secondly the price quote is the highest among all the pros Angi matched me with hence I did not go with these guys."

"Carlton and Tony were extremely professional and knowledgeable. They diagnosed the problem immediately and found where the electrical problem occurred, and why it occurred. They fixed the electrical issue immediately and recommended new GFCIs be installed. They were both great and very friendly, explaining why the outlets were wired in the circuit in the layout of the area in the house. I would whole heartily recommend this company and these two gentlemen for any electrical work."

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
