How Can I Tell If My Home’s Air Quality Needs Improvement?

The best way to understand your home’s air quality is through professional IAQ testing. IAQ stands for Indoor Air Quality, and testing helps identify what’s circulating in the air you breathe every day. Our technicians use specialized tools to measure levels of dust, allergens, humidity, carbon dioxide, and volatile organic compounds (VOCs).

You might already notice signs that your air quality is poor, such as lingering odors, frequent dust buildup, worsening allergy symptoms, dry skin, or that heavy, stale feeling when you walk inside. These are all indicators that your home could benefit from cleaner, fresher air.

Once testing is complete, we review the results with you in detail and recommend practical solutions (such as improved filtration, ventilation, or humidity control) to create a healthier indoor environment for your family.

Complete Indoor Air Quality Services

At Landry Mechanical, we provide a full range of indoor air quality services designed to improve comfort and well-being in every room of your home. From removing airborne irritants to balancing humidity and enhancing ventilation, our IAQ solutions are built to create a healthier, more enjoyable living environment for your family.

Air Filtration and Purification Systems

We install whole-home filtration systems that capture airborne particles such as dust, pollen, and pet dander. For even cleaner air, we offer advanced air purifiers that neutralize bacteria, mold spores, and odors.

Humidifiers and Dehumidifiers

Maintaining the right humidity level helps prevent dry air in winter and sticky, damp air in summer. Our team installs and services humidifiers and dehumidifiers to keep your air comfortable and balanced year-round.

Air Duct Repair and Installation

Your ductwork plays a major role in how clean and efficient your home’s air system is. We provide professional air duct repair and installation services to eliminate leaks, improve airflow, and ensure your HVAC system delivers balanced comfort throughout every room.

Ventilation Solutions

Proper ventilation is key to keeping indoor air fresh. We provide solutions that bring in clean outdoor air and remove stale indoor air, improving circulation without sacrificing energy efficiency.

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.

Our entire experience with Landry was excellent. We needed to replace our water heater. The office people started it off well by being friendly and helpful. They were very thorough in giving us our options in the quote. They got it done quickly and even simplified some of the pipe work from the previous set up. Looks great and works great! Very happy we used Landry!

Mine was just an annual tune up. Mr . Torres showed up well ahead of time and got the job done in no time. He took all my questions and proved himself to be very knowledgeable in what he does. The job is half done and the rest is expected to be done soon but i am fully satisfied and will be knocking on Landry’s door next year for another tune up, God willing!

We had an outstanding experience from start to finish with Landry HVAC, plumbing and mechanical. Tim L. came out to assess our cooling needs and utilized a LiDAR scanner to ensure that our rooms were properly fitted with the right-sized mini-split units. He addressed every question we had, which set a wonderful tone and made us feel completely comfortable and confident in our decision to move forward with Landry.

Avah served as our dedicated point of contact, and both she and Tim provided prompt, kind, and clear communication throughout the entire process.

Gavin, our lead technician, did an incredible job and is truly a star in his role. He was professional, communicative, and thorough in explaining every step of the installation. We are very pleased with how Gavin and our second technician, Kyle, handled the units, wiring, covers, and the condenser. Gavin provided us with information on how to use, clean and maintain our new mini split units. They were incredibly respectful of our property and took great care to keep our home clean. Additionally, Don the electrician did fantastic work with the electrical components to ensure our system was running safely and smoothly.

This was truly the "dream team," and I cannot recommend Landry highly enough. We will certainly utilize them for all maintenance and future services for our home.
