"The company was paid to diagnose and fix a leak to my roof. They determined that a small patch of roof needed to be replaced. A couple of weeks later the leak continued from the same spot in the ceiling. The tech again came out and claimed it was another leak in a different spot although the leak inside was in the exact same spot. They did not fix the problem the first time and wanted more money for this “new leak.”"

"We were referred through Menards. Ronald Lyman blamed my husband and told him he burned up the engine. This was a new power wash that was used once and then broke. It was under manufacturer warranty but needed the gas out and something from him saying it was broken for Menards to return. He has hidden diagnostic fees of $40, no contract verbal or written for these fees. He did not tell us about the fees until we were ready to pick it up. I was under the impression that he was contracted through the company and that is how he is paid. He also told my husband that he didn't look how he sounded over the phone. My husband is from Mexico but has lived in the states for over 35+ years as a naturalized citizen. I am so sick and tired of the racism and people being taken advantage of! I have also complained to the BBB. We are taking the pressure washer back to Menards but because he was not willing to give us something that said it was defective we have to trade it for the same model. So we have paid $40 above the price. Ronald Lyman told my husband when he picked it up that he didn't listen just like his wife. He is very disrespectful. Then he tried to say he called the manufacturer and they were not familiar with the engine, that it was made in China dn told him not to get another one."

Generator Install questions, answered by experts

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

If your home already has a grinder pump and you’re still noticing issues (like frequently clogged toilets and sinks), it could be time to upgrade your grinder pump. Start by checking your existing horsepower. If there are four or fewer people living in your home, using a 1/2-horsepower grinder pump should be sufficient. Larger households should consider investing in a 1-horsepower grinder pump to maximize wastewater removal efforts.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more.
