Important Considerations for Commercial Electrical Work

Landry Mechanical Inc Plumbing HVAC & Electric takes every detail into account to ensure each project is completed safely and efficiently.

Key considerations include:

  • Load management: Electrical systems must support heavy equipment, lighting, and HVAC systems without overloading circuits or reducing performance.
  • Code compliance: Commercial facilities must adhere to strict electrical codes and inspection standards to maintain safety and avoid costly violations.
  • System longevity: Quality components and regular maintenance extend the life of your electrical infrastructure and minimize downtime.
  • Energy efficiency: Upgrading lighting, wiring, and power systems can lower utility costs and improve overall building efficiency.
  • Minimal disruption: Our team plans work around your business hours to keep daily operations running smoothly while we complete installations or repairs.

I had an excellent experience with Landry Plumbing. Dennis installed my new hot water heater, and he was outstanding from start to finish. He was extremely ~> knowledgeable, thorough, and took the time to explain everything he was doing, answer my questions, and even point out other plumbing issues that may need attention in the future. I really appreciated how informative, professional and down to Earth he was.
His assistant, Rickie, was also wonderful! He is kind, courteous, and always willing to help. Together they worked efficiently, kept the work area clean, and treated my home with respect throughout the entire installation.
Their professionalism, attention to detail, honesty, and excellent customer service made the whole experience stress-free. I highly recommend Landry Plumbing, and especially Dennis and Rickie, to anyone looking for reliable, licensed, insured and skilled plumbers. Thank you both for a job well done!!

Garret and Kyle worked from 7:30 am - 6 pm installing a new HVAC system in 100+ degree weather. (Bad timing for the old system to die!) Many thanks to both of them for coming here to install the new system and make life comfortable for us in this sweltering heat.

Aaron and Tory from Landry Mechanical were outstanding. We have a very old HVAC system, and they were able to quickly diagnose the issue and restore air conditioning to our home the very same day. They took the time to walk me through the diagnosis and clearly explained what was wrong and how they were going to fix it. They were professional, clean, efficient, and respectful of our home throughout the entire service call. I really appreciated their expertise and excellent customer service. I highly recommend Aaron, Tory, and the team at Landry Mechanical!

After 25 years our AC needed replacement. Landry used a iPad app to determine the size of the system we needed (we had an undersized system previously which explains why our house never properly cooled down in the middle of summer). They were able to schedule an install the next week. Garret and Kyle did a great job. Super friendly, informative and professional! Couldn’t be happier.
