Sizing a Dehumidifier: Key for Comfort

Schedule Now

There are a lot of reasons you might want to use a dehumidifier in your home. If your indoor air is too humid, it can cause a multitude of problems, including damage to your possessions and home as well as promoting mold and mite growth. By running a dehumidifier, you can take control of these issues — but choosing the right one is key for your home comfort. You can choose a whole house dehumidifier, which works with your HVAC system. You may also want to dehumidify room by room, in which case you will want to choose the right size portable dehumidifier.

Optimally, you want a relative humidity in your home of no more than 40 to 50 percent. If your floors creak, your windows develop condensation, or your allergies have gotten worse, this can be a sign that your humidity is too high.

A whole house dehumidifier needs to be the proper size for the home. Factors to consider are number of rooms, size of the home (square feet) and the unit’s airflow. Consult your HVAC pro for advice.

When sizing a portable dehumidifier you don’t want a model that is too large or too small. A small model is likely to run continuously, but never lower the humidity to comfortable levels. A model that is too large is generally preferable, but is usually more expensive and unnecessary.

Portable dehumidifier size is shown in pints. This is the amount of moisture it can remove from the air in a period. Consider the location’s condition prior to the dehumidifier. The more humidity it has naturally, the larger model you will need to maintain the area. A small (500 square foot) room that is moderately damp may only need a 10 pint humidifier, while the same room that is naturally extremely wet could need a 16 pint humidifier. As the room gets larger, the necessarily capacity for the dehumidifier does as well.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
