"Responsive, fair pricing. Quality of installation could have been done a little better as rods were slightly crooked and they did not pull the wiring tout on top of house so not totally parallel to roof line."

I am a jack of trades independent contractor/ handyman with 10+ years experience. I am not a licensed plumber, licensed electrician, or licensed roofer. With that said it's easier to just tell you the things that I don't do. I do not do drain work, I do not replace electrical lines or panel boxes, I do not replace plumbing lines which includes water and gas, and I do not replace roofs. Aside from that I can do everything else, and have the tools to do so.

"Our house had a water damage that ruined much of the drywall and floor on the first floor and the basement. For such a big repair job, I carefully looked up the reviews and recommendations from Angie's list and talked to 3 contractors that have the highest ratings. AOM was one of the three. David, the owner of AOM, quickly came to our house, assessed the damage, explained to me what need to be done, showed great empathy to our loss and current situation (having to stay in hotel waiting to go back to our house), and put a very competitive bid (about 2/3 the bid of another contractor). We picked them and signed the contract. AOM uses Trello, a cloud-based project tracking system that software companies often use, to effectively and promptly communicate task description and updates to all workers and house owners. AOM workers are professional, hard working, and friendly. For such a big project, expectedly there were some hiccups and AOM had to juggle ours with their other on-going projects. David kindly explained to me various aspects of the repair work and promptly fixed any faults that we identified. I became to completely trust David's professional skill and that he would treat our house like his. Several nights and weekends David came to work late so that we could move back to normal life as soon as possible. In the end, we are very happy with our remodeled house. I sincerely recommend David and AOM for any house remodeling and restoration job."

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
