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.

From the sales team (Tim) to the installation team (Keith, Zach, and many more) these folks have done an outstanding job removing our old system and installing a new full HVAC system.

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.
