Aquarius Home Services is the top home service provider in Minnesota and Wisconsin. Offering expert service in HVAC, Water Softeners, Plumbing and Electrical . Our work is backed by a 100% performance guarantee.
"Nick was waiting for me when I came back from an errand. He was very good at explaining what he was going to do, then did it, then explained what he found. Very professional! Aquarius should tweak their scheduling plan to incorporate windows of when the tech will arrive. The current method of announcing that the tech will be there without stating when is very inconvenient for the homeowner."

"Worst company that I have ever worked it. In my experience, plain dishonest. They have not only made a terrible job on my furnace installation (which replacement need was questionable - my mistake of agreeing to it), they also damaged my perfectly working AC. Now, they are giving me the run around for 4 months to refund the AC damage. I've been calling multiple time per week and also went in person to their office. Before wasting your hard-earned money, pay them a visit at 9609 Girard Ave S, Bloomington, MN 55431 and get inside the office, then make your decision."

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
