The Importance of Carbon Monoxide Detection

Carbon monoxide is often called the “silent killer” because it has no smell, taste, or color, yet even small amounts can cause serious illness or be life-threatening. It’s produced when fuel-burning appliances such as furnaces, fireplaces, water heaters, or gas stoves don’t burn fuel completely, allowing the gas to build up indoors undetected. Installing a carbon monoxide detector is one of the most effective ways to protect your family, providing an early warning when levels begin to rise and giving you valuable time to act. Professional installation from Landry Mechanical Inc Plumbing HVAC & Electric ensures detectors are placed correctly near sleeping areas and fuel-burning equipment, keeping your home protected at all times.

I have been having issues with my old oil furnace. These amazing people have come the day I called and I think they got it. What I really liked was that they consulted each other with work that had been done. They are friendly and professional. Louis came today and his parting words were: " don't worry , we are here for you".

I highly recommend Landry Mechanical and cannot say enough about their services. When the gas water heater in our rental unit flooded the basement, I wasn't sure who to call or how soon I could get someone there. I remembered Landry had serviced our gas furnace and checked their web site to see if they also did gas water heaters and discovered they offer a whole range of services I wasn't even aware of.

I called Landry about 8:30 in the morning and the scheduler said they could have someone there by noon. They beat that estimate - I got a call from the technician who said they were on their way and would be there about 10:15, less than 2 hours after I called. They first assessed the situation, had a lengthy discussion with my husband (a retired contractor) who had lots of questions, all of which were answered thoroughly and to his satisfaction. When it was determined a replacement was necessary - no patching or temporary fix - they had the same model on the site within the hour. The work was prompt, clean, and met my husband's stringent standards.

Now that we know they also provide full electrical services, we will be calling them to add an electric panel to our rental property. Our previous electrician has been delaying the job literally for months, despite back and forth emails and texts to try to get him on site. Having earned our trust and demonstrated the quality of both their people and their work, Landry Mechanical is now our “go to” for any services we need.

The tech showed up on time and proceeded to do my annual gas furnace inspection, which I am happy to say passed with flying colors. The tech was personable and didn't mind that I tend to hover while she worked. Always had excellent service from Landry.

Highly recommend Landry Mechanical! I hired them for installation of a new HVAC/ heat pump. From sales to installation… great customer service, responsive to questions, and professional and friendly team. They talked through all options for my heat and cooling needs so I felt it was a collaborative process. It’s a big expense and I felt they had my best interests in mind.

I have a boiler maintenance plan with Landry. They completed startup service for our condensing gas fueled boiler . My wife & I are retired engineers. Eddy the technician is very knowledgeable and worked efficiently. His customer service skills are excellent! He patiently answered all our questions & fully explained his inspection findings. He quickly put a proposal together, got our approval to proceed and went to get the new parts needed. The boiler maintenance was done in an hour.

And So the boiler is ready for reliable service this winter. Thanks Landry!

Technician arrived right on time. He (Anthony) was friendly, courteous and very professional. Anthony listens carefully to the issues and then provided a reasonable and practical solution. Overall cost was reasonable. My only concern is that it is not easy to talk to a human being during the booking process. Have to go through an IVR then a AI bot. Company could make the engagement process easier and less complicated.
