Installing a whole home humidifier makes sense in a dry climate especially for those suffering from allergies and other ailments related to dry air. There are many ways to have a whole home humidifier installed. One way is to have a general contractor install it. Or, you can install the humidifier yourself.
Having a professional licensed contractor install a whole home humidifier is a better option for those who are unfamiliar with home improvement projects – having a professional installation with a guarantee is even better. And other times, a licensed contractor may be the only option if building code or a homeowner’s association policy requires it.
Doing-it-yourself can save you money. Whole home humidifiers are easy to install if you are familiar with home improvement projects and HVAC systems. You must have knowledge about the electrical wires, water lines, and air ducts in your home. Before doing this project, it is important to check local building codes in your area to see whether you will need a permit. Checking with your homeowners insurance is also recommended.
When buying a whole home humidifier, look for one that is made for the size of your house as well as the type of humidifier. There are three types of humidifiers: drum systems, flow-through systems, and spray mist systems. Having a humidistat allows you to control the humidity level. Each humidifier system varies from manufacturer to manufacturer, but they all share the same basic installation. Following the instructions for the humidifier is recommended.
Before tackling the installation, it is important to shut off all heat and electricity. Some tools will be needed for the installation, and they will be noted in the installation guide that comes with the humidifier. Locate a suitable place for the humidifier near the furnace. The humidifier will be placed in the air duct. You’ll need to drill and cut into the air duct to fit the humidifier. The metal edges will be sharp, so it is important to wear gloves for protection. Some systems will allow for a by-pass gate, so additional space is important. You will then mount the humidifier in the cut-out with the provided screws.
When you have the humidifier installed in the air duct, it is time to shut off the water supply to connect the water valve to the water line using the provided hose in the kit. The water supply valve is a tap-fitting type which clamps on the water line and the valve stem has a sharp point which pierces the water line. When the water supply valve is attached securely, you then connect the hose between the valve and humidifier.
Installing the humidistat requires a mounting plate to hold it. The wires are then connected to the humidifier and a transformer which reduces the voltage from the house current.
After the installation is complete, it is time to test the unit. Turn on all utilities that were shut off for the installation, then check to see if everything running smoothly. Always keep the instructions and other important documents for the project.
