How a Whole-House Generator Works

A whole-house generator connects directly to your home’s electrical panel and automatically activates when the main power supply goes out. The system uses a transfer switch to detect the outage and start the generator within seconds, delivering steady power to your essential appliances, HVAC systems, and lights. Once utility power is restored, it shuts off and resets itself for future use. Running on natural gas or propane, these generators provide reliable, hands-free operation that keeps your home safe and comfortable during any outage.

Furnace wasn't setup properly when first installed. Ended up costing me thousands more over a couple years in electrical vs propane heating fuel. Fortunately Samy listened to my issue thoroughly and was able to find the issue. He also provided a backup setting in case the issue persisted. He was friendly and professional. Landry also waived the service fee, although they did come last year within the warranty for the same issue and didn't fix it then, so this is understandable.

I cannot recommend Landry Mechanical enough. We happened to have issues with our heater the week before our newborn baby was due. We had the entire HVAC replaced to a heat pump which happened to overlap with the week we brought our newborn home. The project took 5 days and every single person who came into our home was kind, courteous, respectful and cognizant of our new baby. Josh, the project leader was amazing. Highly communicative, super nice, and respectful. There was alot of work going on but the team made it into the best possible situation it could have been. We are extremely grateful. The heat has been working great!
