FAQs
How do I determine the right size of dehumidifier for my space?
Determining the right size of dehumidifier for your space depends on various factors. First, calculate the square footage of the area you want to dehumidify. Next, consider the relative humidity level and any specific moisture issues. For moderate humidity, a general guideline is to select a dehumidifier with a capacity of 10 to 12 pints per day per 500 square feet. However, a larger capacity may be necessary for high humidity or severe moisture issues. Additionally, factors like room temperature and airflow should be taken into account.
Can a dehumidifier be used in basements or in cold temperatures?
Dehumidifiers can be used in cold temperatures and basements. However, not all models are designed to operate efficiently in cold environments. Look for dehumidifiers with built-in defrost functions or those specifically labeled for low-temperature use. Dehumidifiers in basements are particularly effective as they help control moisture levels and prevent mildew. Ensure proper ventilation and use a dehumidifier that suits your space’s size and humidity level.
What is the ideal humidity level to maintain with a dehumidifier?
The ideal humidity level to maintain with a dehumidifier is typically between 30% and 50%. This range helps prevent dust mites, and allergens while creating a comfortable indoor environment. However, preferences may vary, so it’s important to find a humidity level that suits your needs and ensures the well-being of your space and health.

We have used 2nd Wind for years and I could not be happier with them. Every single technician we’ve had has been so kind and friendly. They have come out in the middle of the night for us and been just as nice. We just had a lot of work done (ductwork and new water heater) and when they left there was not a speck of debris/trash left anywhere; you would never have known they were here. They made sure we understood how everything worked and that we had all our questions answered. I love this company!

We had a great experience. All the technicians were great and good workers. The follow up gentleman made a slight change in how to change the filter that made it better for me. Would recommend them to anyone.

10/10 would recommend. My air ducts desperately needed replacement. 2nd Wind was the only company to return my call once I began the search. They had me on the schedule the next day for an estimate and began the job the following Monday, a three day job. The installers were very professional, friendly, and responsible. I was even loaned a window unit during the job.
