"We called Dalcon Electric when a car struck a power line outside of our building and knocked out the electricity to our building. They were quick to respond in an emergency, courteous and professional. They helped us get our business back on track in a pinch. Then, we hired Dalcon to replace all 53 outdated outlets in our building. Dave and his crew (Jack and Billy) completed this efficiently and with minimal disruption to our business. When we needed to install emergency exit signs, Dalcon provided by far, the best quote for the work to be done compared to many other handymen we had considered. Jack and Billy installed our emergency signs and cleaned up the area where they had worked leaving it just as, if not better than, how they found it. Everyone at Dalcon is courteous, prompt and responsive. Dave, the owner, came in person to our office to discuss each project to be done. Scheduling these projects was a breeze, Sarah and Suzanne in the office were very responsive and made sure our concerns were addressed. We scheduled the projects out over time, but when a sooner date became available, someone from Dalcon would call and ask if that time would work for us so we could have our projects completed sooner. We would definitely work with Dalcon Electric again."

"Everything went fine with the exception of the fan install which was pretty tricky - we have some funky wiring done in the 80s by the old homeowner. Otherwise, great - Marcus got out to our house quickly and there were A LOT of lights/switches/exhaust fans to install which were taken care of quickly and at a reasonable price."

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 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.
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
