"You want an honest HVAC company? Look no further. Dave and his crew were the only people who would come and fix our boiler wiring- everyone else was either too busy or refused to deal with a smart thermostat. They came when they said they would, did the work, and charged exactly what I was quoted beforehand. So, when our 20 year old boiler stopped lighting, I called again. And again, he showed up when he said he would, explained what was going on, and charged an exceptionally reasonable price to fix it."

"We replaced the original roof on our house. I expressed my concerns about re-installation of the lightening rods to my roofer. We have had at least three direct hits since they were originally installed in 2013. My roofer called William who was very helpful. William offered to come out an make sure everything was 100% after re-installation. He came the day after I called and I'm glad he did. While the reinstall was the best he had seen (his words) there were issues after 5 year and 3 strikes that needed addressed. He fixed those and now I have a new roof and I am certain the lightening rods will work as intended. Highly recommend this company."

"I have no complaints about Mr. Electric. In fact, the technician went above and beyond and was excellent. He couldn't make it on the day of installation, which was unexpected, but his stand in honored his commitments. The only reason to not give 5 stars was that it seemed excessively expensive. I wouldn't pay that again for what it was. I'd do it myself. Even Angi gave me a reasonable quote. They charge six times that reasonable quote for a simple outlet transfer... 10/10 for customer service. I guess you'd have to be though, for all that money."

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
