How Much Does it Cost to Install a Whole-Home Humidifier?
October 10, 2017
As we head into colder, drier temperatures in Kansas, more and more homeowners are considering a whole-house humidifier. So if you’re in the same boat, you’re probably wondering how much this will cost you when all is said and done.
Well, in Kansas, the average price to install a whole-house humidifier is $600 with homeowners typically paying anywhere between $550 and $600.
The factors that affect the price of your installation include:
Type of humidifier
Professional vs DIY installation
Factor #1: Type of humidifier
How it affects price: Typically, steam humidifiers are more expensive than bypass or fan-powered humidifiers.
The 3 types of whole-home humidifiers include:
Spray humidifiers (sometimes called “atomizing” humidifiers) are the least expensive option but they’re also the least popular.
You see, spray humidifiers add moisture into the air by spraying mist directly into the air stream. The biggest problem with this design is that, over time, mineral deposits often grow on the nozzle of a spray humidifier, causing leaks and inefficient operation.
So, homeowners with hard water (that is, water with a high amount of dissolved minerals, like we have here in Kansas City) should avoid this type of whole-home humidifier.
Evaporative pad humidifiers
Evaporative pad humidifiers are also relatively inexpensive but are much more common than spray humidifiers.
During operation, warm air from your furnace passes over a wet pad. Moisture is absorbed into the warm air and the humidified air then blows into your home.
Two types of evaporative pad humidifiers include:
Fan-powered- uses a built-in fan to draw warm air over the wet pad
Bypass- uses the furnace’s own fan to push air over the pad and into your home
Because evaporative pad humidifiers have less repairs and are easy to maintain (simply change pad at end of each heating season), they’re a popular choice for homeowners.
However, one downfall to both spray and evaporative humidifiers is that they rely on the heat from your furnace to evaporate water into the air. Which means, they can only operate intermittently (alongside your furnace’s heat cycles).
So homeowners who prefer more even, constant dehumidification usually choose a steam humidifier...
Steam humidifiers are the most expensive of all whole-home humidifiers but they are the most effective when it comes to adding precise humidification to your home’s air.
Steam humidifiers use built-in electric probes to boil water to the point of vapor. Then, that water vapor/steam is pushed through the ductwork and into your home. Because steam humidifiers have a built-in heater, they operate independently from your furnace. That means, they can provide constant humidification instead of only during heating cycles.
Factor #2 Size of the humidifier
How it affects price: Typically, the larger the humidifier, the more it will cost.
The size of a humidifier is often measured by the gallons of water that is absorbed into the air in a 24-hour period, noted as “gpd” (gallons per day)
And how much humidification you need really depends on 2 things:
The square footage of your home
The level of insulation in your home (good/average/poor)
Not sure how well insulated your home is? To give you an idea, answer the following questions, the more you answer “yes”, the better your home is insulated:
Is your attic insulated?
Do you have storm windows and doors?
Have you checked your storm windows/doors for air leaks and used weather-stripping to seal off any leaks?
Is your fireplace dampened?

Factor #3: Professional vs DIY installation
How it affects price: Professional installation can add $100-$300 more to the overall cost of a whole-home humidifier installation.
When it comes to whole-home humidifiers, some homeowners prefer to install these units on their own. However, unless you’re extremely handy and have installed a central humidifier before, we don’t suggest trying to DIY your humidifier installation.
Here’s why: Installing a central humidifier requires plumbing, electrical and HVAC knowledge. You’ll need to properly connect your whole-home humidifier to your HVAC ductwork, your home’s electrical system and to the main water line.
Any mistake in the installation can result in you paying more than you should for the humidifier’s operational costs, not to mention, you likely won’t get the humidification levels you needed in the first place.
A professional can also ensure that you get the correct size and model humidifier that your home needs.
