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.

As always, Landry provided professional service, Joe and Natasha were very thorough with the inspection of my AC system and identified a contractor and capacitor they were getting bad on one of the units. They provided several options and were prepared with the parts on the service vehicle the same day. Both Joe and Natasha were very courteous and professional.

We had a slow draining tub and George came to diagnose the issue. We had used a snake but couldn't locate any clog. George was incredible. He put down the drain a chemical that had to sit overnight and followed his instructions to wait until the morning , fill up tub, and drain. The clog does seem to be gone now and water is draining properly. The only complaint we have is that we thought the pricing was a little high for the service performed.
