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.

Evan from Landry Mechanical came last week to do our yearly heating plant review. He explained what he was doing as he proceeded, and completed review and, happy to say, everything was fine.

Update Aug 22, 2026:

We had three separate services completed yesterday and, as we've now come to expect from Landry, every technician was professional, knowledgeable, and courteous. Eddy Russell handled our HVAC maintenance and did a thorough job, explaining what he was doing along the way, adjusting his work order a bit, and completing the job in a timely fashion. Jose Viveiros took care of our plumbing service efficiently, fixed two issues he discovered (Kitchen sink & Bathroom shower), and left everything clean and in great shape. Jonathan Torres installed two mini-split dongles and he and his teammate were prompt, detail-oriented, and made sure everything was working properly before they left. Great communication, quality work, and a smooth experience overall. The only issue I have with to report is not related to the work that was done, but rather the fact that it took many many months for the dongles to be installed. I would have expected some kind of consideration for the prolonged delay. Having said that, I do highly recommend Landry Mechanical.

We engaged with Landry Mechanical and several other HVAC providers in November ‘22 to get bids to replace our aging AC system. The decision to go with Landry was beyond easy, it was a classic no brainer. Between their obvious depth of comprehensive HVAC experience, their knowledge of how to integrate the MASSSAVE incentives into the project, and their commitment to minimizing environmental impact I readily made the decision to leave my long time HVAC provider.

Because of their high value consultative sales approach (Ryan) we ended up contracting with them to replace not just the AC but to install a hybrid ((ductless (mini-split) and duct (heat pump)) system that was completed today under the direction of Jason and with the help of MANY of their team as they worked miracles to complete the install around our hectic holiday schedule. And to top it off, they have guided us through the MASSSAVE process every step of the way so that our actual out of pocket expenses are in part subsidized and part financed at 0%.

In short, without question they have exceeded all my unreasonable expectations from the point of initial engagement to the installation itself. Great team, great customer sensitivity, and now we are fully expecting great reduction in our environmental imprint.

My tankless hot water heat exchanger corroded and failed, called Landry for repair, Landry sent the technician on the same day. Technicians came on time and looked into the issue and worked with manufacturer to get the part overnight shipped under warranty, came next day and replaced the part. Great service.

It starts with the professionalism and courtesy from Anthony and Nick. Not only did they do a great job, but they clean any mess they make. (I know that sounds simple, but you’d be surprised how many contractors miss this point) They kept the noise down to a bare minimum out of respect for my neighbors. They also were working to complete the job from the minute. They came in till the minute they left. Very impressive

Called Landry Mechanical yesterday around noon to request service as we had no hot water. They were very responsive and sent Joe out to see about our problem. Joe arrived around 3 pm, diagnosed the problem and had us back in hot water by 4 pm. Very professional, efficient, responsive to customer. Would strongly recommend.

The installation crew for a water heater and water tank arrived today. They explained everything they were going to do and answered all my questions. The work was very well done and the duo that completed it were helpful, friendly, and extremely competent. This is the second time I have used Landry's. I highly recommend them. I will certainly use them again.

Drew was excellent. He was timely, polite and very knowledgeable. He identified our problem which was atypical with his thorough examination. Even gave us a plan B if the issue should happen again. We greatly appreciated his expertise as well as his teaching. We will definitely be keeping Landry as our provider of choice for HVAC service and products.
