Since 1883 McQuillan Home Services has been Minnesota’s Original plumbing, heating, and cooling company. At McQuillan we’ve always remained true to our mission of providing solid, honest work to all our customers. Join the McQuillan Home Services family as we continue to raise the bar and provide generations of happy customers with quality plumbing, heating, AC, electrical, and drains service.

"Oh, how I wish there were a grade lower than F. McQuillan managed to provide both poor customer service *and* bad technical work. The company came out to do a full replacement of our A/C unit and furnace, switching to minisplits and a boiler/radiator system. The minisplit side of the equation went just fine. The rest has been a disaster. This all started the first week of August, so they would have plenty of time to get the work done before winter...so we thought. Instead the installed the boiler incorrectly, causing it to make loud noises and not actually provide any hot water. After calling five times and having two missed appointments, they finally sent out a plumber who informed us that it was so badly screwed up, an entire crew would have to come out and fix it (which they eventually did, two whole weeks later). It took three people nine hours (!!) to fix whatever they did wrong. Now on to the radiators. Several were backordered to the first week of September, obviously not their fault. Once they called us to say the new radiators were ready for installation, they couldn't "fit us into their schedule" for three more weeks! When they did show up, we found one radiator completely missing, two ordered in the wrong finish, and several others that couldn't be installed because they didn't have the right parts and weren't sure how to get them (WHAT?). And, this is a minor issue compared to everything else, but they ask you to pay as you go, so every time someone shows up they want to collect money. Multiple times we've asked to see an itemized bill so we know what all our payments have gone to (this is a large job and we just want to keep track of everything), but we still have yet to see a single invoice or receipt of our payment. Which brings us to today. We're not currently on their schedule at all. Half of our radiators are installed, but none are active on the system, so we have no heat. It's early October, and the temperature tonight is supposed to reach 35 with a frost warning (which is one things for my husband and I, but we also have three kids under the age of 6). We've called multiple times the past two days and no one will call or email us back to tell us when we are actually going to have heat. I'm extremely close to reporting them to the BBB and calling a different company to finish the job so we can stay warm. I wouldn't wish McQuillan on my worst enemy."

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."

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
