"They werenâ t able to install lighting in my brick pillars after I purchased new lights per their request. They said the pillars would probably need to be taken apart to find the problem.They did some rewriting work and it was ok."

"CD Electric was fantastic. They added electrical outlets to the interior and exterior of my home and installed an exterior light. Chase was very thorough with the estimate he provided me and completed the job in the time he said it would take. I would definitely hire them again for any future jobs and I highly recommend them to anyone else."

"Gentleman who owns Solarize was professional and courteous. He communicated well with the manufacturer and convinced them that a replacement inverter was needed based on the data he saw and the manufacturer had seen. It's what we were hoping for."

"The owner of Electronics 9-1-1 installed an eight-camera home security system in my home. The entire experience, from initial consultation to finished product, was the model on which all other advertisers' services on Homeadvisor should be based! The company owner's recommendations about installation techniques, technical knowledge and considerations, equipment capabilities, scheduling accommodations, and modifications in mid-installation to overcome unforeseen issues were all spot-on, and resulted in a system that exceeded every expectation. Would use Electronics 9-1-1 again in a heartbeat, and it is a pleasure to recommend them to anyone needing security system installation or service of the highest quality."

"Lead Electrician Mike Liefer and Trainee Brian Mehring were Great! Superior Craftsmen, Very personable, Friendly and explained in detail all questions I had for 2 separate projects! #1 project was changing out my 100 amp service to a 200 amp in my 113 year old home, then installing power to a new 2 HVAC units in the basement and attic. I am a retired Structural (Carpenter) Craftsman of 45 years, (20 years USAF) 25 years Civilian. Very particular! After closely watching them I realized I could not hired anyone else. PES was very reasonably priced and quick to get a quote and start date!! I recently had a siding crew with great reviews, but were a awful in their trade...WISH I would have know about PES."
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
