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.

They did an amazing job replacing my ac system. My mom came home on hospice on a Wednesday. And my central air died that same day. Called them and they came right out Thursday morning to diagnose the problem. Tuesday the following week they were here bright and early. They finished up the install Wednesday. They were professional, neat clean and prompt. I highly recommend them!

I had a scheduled annual check up of my furnace, which was installed around nine years ago. Corey was very nice. Let me know everything was fine. Gave me a couple of optional upgrades. If I was interested Landry get me informed as to when Cory would be showing up. I like the fact that they are certified employees. Great company. UPDATE. My annual furnace update again by Joe and again had a wonderful experience with Landry He was very thorough explained everything no pressure to take his suggestions which I know I will do just not at this moment. I do appreciate the staff and the service that I get from Lang.

Clean, respectful, responsive, polite and knowledgeable. Now a days these qualities are scarce and not to be taken lightly because the competition costs as much (or more) and they will trash your house and talk to you down when you ask for a description of the problem… I only say this because it was part of my personal experience with a different company and it was very discouraging.

Your guys were very professional and explained everything in detail. Snaking a drain can be very messy but they keep everything clean and organized.
