"I had an excellent experience with Stephanie, Tim, and Spencer during the installation of my mini split system. From the very beginning, they were professional, friendly and communicative. They took the time to explain how the installation process would work and made sure I understood all the benefits of swtiching to the system. I felt well informed and supported. Since the installation, the system has made a huge difference in my hosuehold. The units are quiet, efficient, and give me the ability to control the temperature in all rooms in my household. Not only does it keep the space comftorable by replacing AC's but I've noticed the air quality and drop in my electricity bills are better. I"m grateful for the work this team did and would recommend them toothers. I trust them completely and wouldn't hesitate to use them in the future again. Thank you!"

"Adam called me immediately and met me that same day. I hired the company and they cut my grass that same day. They used a ride on mower and my land is uneven so some areas were shorter than others. Two days later they spread 10 yards of hemlock mulch and recut some areas of my grass with push mower. They will use a push mower in the future. My yard now looks beautifully landscaped. Communication is definately key with this company. They aim to please!!"

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
