"Service Requested : Electrical panel replacement, dryer circuit, bedroom circuit & quad outlet. The crew were early, dedicated and doggedly determined. Day one was a the long pole, the panel replacement. They didn't stop until they were done. Went to sleep in a warm bed that very night. Next day they returned to wrap-up the dryer & bedroom circuits. They were thorough. They did the "best effort" and took no shortcuts. And the quote was much lower than every other (I obtained 7). Completely and happily recommend them."

"I requested an HVAC service call quote from G&S Heating through Angi, and received a "deal" via Angi for $129. I chose them partly due to that price. G&S Heating ended up billing me $280, and said that was an old outdated deal and would not honor it. Irresponsible and incredibly poor customer relations. Also, the technician they sent did not seem very knowledgeable or experienced. He said the thermostat reading issue I was having would require another service call and the possible replacement of an expensive circuit board. I ended up fixing the problem myself. I will not be using G&S Heating again."

"We had replaced the range in a rental home. When the appliance delivery store arrived, they called to tell me that the 220v outlet was setup for a dryer not a range. They wouldn't install the range until I had the outlet replaced with a correct one for a range. I was eager to find someone to replace the outlet quickly, to get our tenant setup ASAP. I posted the job on Angi and In-House was one of two electricians that replied. They wouldn't give me any kind of estimate or minimum trip charge before heading out. Based on the generally favorable reviews, I decided to let them go out. On arrival, they quoted me more than double what I was quoted from another electrician (who I didn't hire because even that seemed too high). These guys charged me $662 plus tax to swap out a single outlet (admittedly a 220v outlet). I ended up letting them do the job because I wanted to get the job completed so my tenant could use their new range. But the charge was in my opinion outrageous. "

Generator installations FAQs
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
