Humidity can make your home feel uncomfortable, even when the thermostat is set right where you want it. For families with central air, a whole-home dehumidifier is the best way to manage humidity in any season.
Key Takeaways
- An air conditioner or heat pump removes some humidity but isn’t as effective on humid summer days or rainy spring and fall days.
- A dedicated whole-home dehumidifier sits within your central air system and manages moisture without over-stressing heating and cooling equipment.
- An HVAC contractor in Suffolk County can integrate a dehumidifier with your existing system or a new installation.
What is a Whole-Home Dehumidifier
A whole-home dehumidifier is a dedicated appliance that integrates with your central HVAC ductwork. It’s more efficient than a portable unit that only treats a single room. It’s usually installed near the air handler or furnace, in the basement, attic, or a utility closet.
- The system treats humid air pulled from your return ducts.
- Air passes over a coil in the dehumidifier. Moisture condenses and drains away.
- The treated air is then routed back through the supply and distributed throughout your home.
Because a whole-home dehumidifier sits within the ductwork, it treats every room in your home at once. You won’t need to worry about some spaces being humid or damp, like you might with a portable standalone dehumidifier.
The system also runs independently of your thermostat’s temperature calls, so it can manage humidity even if your furnace or air conditioner isn’t running.
A Dehumidifier Works Best in the Shoulder Seasons
Air conditioners and heat pumps in Suffolk County do remove some moisture as a byproduct, but that only happens if the system is running long enough for the coil to get extremely cold and pull water from the air. Dehumidification efficiency if you’re only using an air conditioner or heat pump peaks in summer and is reduced during the rest of the year.
You are most likely to notice humidity problems in the shoulder seasons of spring and fall, or on mild, rainy summer days. Outdoor temperatures might be low, so there’s little demand for cooling, but humidity levels are often high.
- Your thermostat will be satisfied with just a few minutes of runtime.
- The system will shut off or switch to a low-power maintenance mode (in a variable-inverter system).
- A traditional single or two-stage system will short-cycle and leave your home feeling clammy. The temperature will look fine, but you won’t be comfortable.
A dedicated whole-home dehumidifier solves this by running independently of the cooling cycle. It will pull moisture from the air on a humid day, without relying on your air conditioner or heat pump.
Nighttime Humidity Often Increases as Cooling Demand Decreases
Evenings are the ideal time for a dehumidifier to run. As outdoor temperatures drop, your air conditioner’s load will drop with it. Your system runs less often, or at a lower setting, while relative humidity in your home increases.
A whole-home dehumidifier will keep working through the night, helping maintain a 30% to 50% relative humidity target.
