  • System longevity: Quality components and regular maintenance extend the life of your electrical infrastructure and minimize downtime.

Frequently Asked Questions

Hear From Our Satisfied Customers

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.

Five Stars -- Landry Mechanical Delivered from Start to Finish When our heating and cooling system gave out, we needed a company we could trust to move fast, communicate clearly, and get the job done right. Landry Mechanical checked every box. From the initial diagnostic visit on our failed system to the completed installation of our new heat pump, the turnaround was remarkably quick. There was no waiting around for weeks wondering what came next. They assessed the situation, quoted the job professionally, and worked with us to design the right system for our home and our family's needs. The quote itself was straightforward and thorough -- no guesswork, no surprises. The install team was outstanding. They worked cleanly, moved efficiently, and left the job fully complete. This was not a crew that cuts corners or leaves loose ends. Every phase of the project felt organized and deliberate. What really stood out was their communication. Before anyone showed up at our door, we received clear notice of who would be arriving and when. Every update along the way was prompt, professional, and easy to understand. In an industry where homeowners often feel left in the dark, Landry Mechanical kept us fully informed throughout the entire process. Perhaps the simplest testament to their reliability: they said they would be there, and they were. Every time. If you are in the market for HVAC work and want a company that respects your home, your time, and your investment, I would not hesitate to recommend Landry Mechanical.
