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.

Julian did an outstanding job replacing my old central AC with a cold-climate heat pump. He worked hard and stayed late, getting the job done in just two day. It is clear that he takes immense pride in his craftsmanship. The setup is clean, professional, and organized. Most importantly, everything works perfectly. The system is running smoothly, efficiently, and exactly as promised. Tim was also great. He help me pick the right system and guided me through the process of qualifying for the Mass Save rebate and 0% loan. I am incredibly grateful to the entire Landry team for making this such a smooth and stress free project.

I cannot say enough about Landry and their crew. Gavin, Anthony, JT, and Mike did a phenomenal job installing our mini splits. They showed up on time, stayed late, and worked clean. Unfortunately, My husband had a medical emergency while they were working and they stepped in and handled the situation until help arrived. If they didn’t step in it would’ve been so much worse. We will need our boiler and hot water tank replaced in a few months and will be calling Landry back to do the work. We now have a go to company for all of our plumbing needs!

Landry has been looking after my HVAC system for a couple of years now and I have been very happy with their work. The expertise of the technicians is evident, they are always thorough and effective in their work. If the occasion arises they will go the extra mile--for example recently hard wiring my thermostat so I don't need to worry about batteries. As a bonus, I have found them all to be just nice people to have in my house.

The LAST time Landry was here, it was to replace another pipe elbow and a bit more. The technician replaced that OK. However. What the technician DID NOT do fine was turn off the water beforehand. Instead of turning off the water to only my townhouse, he turned off the water to my entire building. This is very bad, because it can mess up the water and pipes for the other tenants in my building. He guessed on the valve. What he should’ve done was ask me which valve it was, instead of guessing. I am NOT happy. The job was ok.
