High humidity can make your home feel sticky, uncomfortable, and unhealthy. Excess moisture in the air can also lead to mold growth, musty odors, and damage to wood, furniture, or walls.

These systems quietly remove excess moisture from the air, helping you enjoy a cleaner and more comfortable home. Don’t wait until the problem becomes out of control. Call our Landry team today to set up your dehumidifier service. It’s your home! You deserve to be comfortable.

How a Whole-House Dehumidifier Works

A whole-house dehumidifier connects to your HVAC system and pulls warm, moist air from your home’s return ducts. As the air passes through the system, excess moisture is removed and drained safely outside. The air is then recirculated, leaving your home cooler, drier, and far more comfortable. These systems work automatically and efficiently without the constant emptying or upkeep required by portable units.

While a humidifier adds moisture to dry indoor air, a dehumidifier does the opposite. It removes excess humidity to prevent that sticky, heavy feeling in your home. Both systems are designed to keep your air balanced and healthy, working together to maintain the ideal comfort level throughout every season.

Dehumidifier Services for a Healthier Home

At Landry Mechanical, we provide a complete range of dehumidifier services for homeowners across Massachusetts. Our goal is to make your home feel comfortable, clean, and free of the excess moisture that can cause damage or discomfort. Whether you’re installing a new system or maintaining an existing one, our team brings experience, precision, and care to every project.

Dehumidifier Installation

We install whole-house dehumidifiers that work in harmony with your HVAC system to keep humidity levels balanced across your entire home. Each installation begins with a detailed assessment of your space to ensure the system is sized and configured correctly. The result is smooth, efficient operation and a noticeably drier, more comfortable indoor environment.

Dehumidifier Maintenance and Repair

Regular maintenance helps your dehumidifier run quietly and efficiently throughout the year. Our technicians check coils, drain lines, and controls to make sure moisture is being removed properly. If a problem occurs, we provide quick and dependable repairs that restore performance and comfort.

System Replacement and Upgrades

If your old unit is no longer keeping up or has become inefficient, we can help you upgrade to a new, high-performance model. Modern systems use advanced technology to maintain ideal humidity levels with less energy and less noise. We’ll help you choose the right replacement to match your home’s size, HVAC setup, and comfort needs.

Humidity Testing and System Balancing

Finding the right humidity level is key to maintaining healthy indoor air. Our team performs professional humidity testing to determine your home’s moisture balance and identify any problem areas. Once we have your results, we adjust and fine-tune your system to deliver consistent, comfortable air year-round.

Corey Menard is a STELLAR human being as well as an EXPERT HVAC technician! He cheerfully and swiftly diagnosed an in-wall heating pipe burst, repaired it, and added a much-needed shut-off valve for one of my (three) heating zones. My English language dictionary does NOT contain the words I need to express my gratitude toward him, or express my gratitude to Landry for sending Corey to my home on Wednesday 02/11/2026. Thank Corey, thank you, and thank Corey!
