In areas that experience very dry Summers or Winters, homeowners often decide to treat their air to higher levels of moisture through the use of a humidifier. Whole house humidifier repair is often needed over the years to keep a system working optimally. Depending on the type of humidifier you have and the nature of the problem, the cost will vary.

Types of whole house humidifiers include:

  • Furnance-mounted: These units are attached either to a warm air duct or a return duct. The blower motor from your HVAC unit will direct air into the unit and initiate the humidifier control board.
  • Pedestal style: Unlike a furnace-mounted unit, pedestal units are stand-alone and require water to be added and have their own humidistat units onboard.
  • Flow-through: On these models, a waterfall-style technique is applied where water falls from the top of the unit across a mesh board which wicks moisture into the air. Water collects in either a ground drain or a reservoir.
  • Drum: A drum unit has water collect inside of a tank containing a drum. The drum rotates and is lined with a mesh grid that wicks moisture into the air as it slowly turns. 

How Much Will It Cost To Repair My Whole House Humidifier?

The final price you should expect to pay to accomplish a whole house humidifier repair will range anywhere between $100 and $500 depending on the type of unit you have and the nature of the repair work needed. The average cost to repair your whole house humidifier is $200. A professional repair specialist will be able to visit your home and provide you with a precise estimate for repair parts and labor charges.

Common types of problems with a humidifier:

  • Furnace control board malfunction: The control board on your furnace is the computer microprocessors that regulate the system and detect humidity in the air. This chipset manages the electrical on and off signals for the unit. If a control board shorts out, it can usually be replaced for less than the cost of a new unit.
  • Clogged valve in your water supply line: If a clog occurs on your water supply line, it is usually a quick and rather affordable fix for your whole house humidifier repair specialist.
  • Humidistat problem: The humidistat is the part of the system the detects your humidity level and regulates when the unit should turn on and off. It is connected to the unit's control board and it can occasionally develop a loose connection. 

You'll want to make sure that your humidifier repair work is all taken care of before the fall and winter months arrive, as those are the most common times when homes become unbearably dry. Occasionally, you'll need to address repairs in the summer time as well when your unit is unable to detect the level of humidity in the air and fails to shut off as intended.
