Humidification & Dehumidification in Bloomfield, New Jersey

Between 30 and 50 percent relative humidity is the range the EPA recommends. Going below 30 percent in winter is too dry for comfort and bad for hardwood floors and furniture. Going above 60 percent is where mold and dust mite populations start to grow, even when you can't see them. The target shifts slightly by season: winter often runs 30 to 40 percent because cold outside air can't hold much moisture; summer often runs 45 to 50 percent because the AC is pulling humidity out as it cools. A whole house humidifier and a whole house dehumidifier between them hold the home in the right range year-round.

It depends on the house. Older homes in this part of New Jersey often need both: a humidifier for the dry winter heating season, a dehumidifier for the muggy summer or for a perpetually damp basement. Newer, tighter homes sometimes only need a dehumidifier because the building envelope holds moisture in better. The first step is a walkthrough to look at where humidity issues actually appear, so you don't end up installing something you don't actually need.

No, when it's installed correctly. A whole house humidifier ties into the supply duct downstream of the furnace and adds water vapor to air that's already moving through the system. The most common installation problems we see on older systems are improperly drained units that leave standing water in the duct (which can grow mold in the place that's supposed to be preventing it) or oversized humidifiers that push the home above 60 percent and condense water on cold surfaces like windows. Proper sizing and proper installation prevent both.

Less than people expect. A whole house humidifier needs an annual evaporator pad replacement and a check on the water inlet valve and drain. A whole house dehumidifier needs a coil cleaning and a drain check, usually as part of the same annual HVAC service visit. Filters on either unit, if equipped, get changed on the same cadence as the rest of the HVAC system. Most homeowners don't think about the equipment between annual maintenance visits, which is the whole point of going whole-house instead of portable.

Not exactly, but they complement each other. Your AC removes humidity as a side effect of cooling, but only when it's running. On a cool but humid day, the AC may not cycle on enough to dehumidify the home, which is when basements and lower floors get muggy. A whole house dehumidifier runs independently of the AC and targets humidity directly. The two together hold the home in the right humidity range across more conditions than either one alone.
