It’s nearly summer! That means it’s time to do all the last-minute summer prep you’ve been putting off. That might be cleaning up the yard, getting your new AC installed – or taking the cover off your old one – opening the pool, and getting out the patio furniture. But don’t forget to switch your humidifier off! If you’re confused or never heard of this before, we’ll explain how and why to turn off your humidifier for the summer.
Why You Should Turn Your Humidifier Off in the Summer
First of all, this only applies to flow-through humidifiers, which are attached directly to your home comfort system. Single-room and portable humidifiers do not need to be adjusted. If you have a flow-through humidifier, it’s time to turn it off. Why? Read on to find out.
Prevent Excess Humidity
Summer is already a more humid time of the year. If you’re running a humidifier on top of that, it could lead to excessive humidity in your home. Overly high humidity can wreak havoc on your HVAC systems, furniture, floors, and air quality.
When there’s too much moisture in your home, it can:
- Damage wood furniture & floors
- Force AC to work harder
- Contribute to mould and bacteria growth
- Worsen indoor air quality
Therefore, switch off your humidifier in the summer to prevent excessive humidity levels in your home.
Lower Utility Bills
As we mentioned, high humidity makes your home feel warmer than it actually is. This causes your air conditioner to work harder than it needs to, which lowers its efficiency. It’ll also run longer to try to cool down your home, putting strain on the whole system. This results in more energy consumption and higher utility bills.
Turn your humidifier off in the summer for the sake of your energy costs!
Help Your Cooling System
We repeat: running a humidifier in the summer can lead to excess humidity which puts strain on your AC. High humidity levels force your air conditioner to run longer, work harder, and ultimately strain itself to cool your home. Not only does this negatively affect your home comfort, but it also eats up energy and costs you more in utilities.
Help your cooling system by turning your humidifier off for the summer.
How to Turn Off Humidifier
You need to switch the damper to the “Summer” position and turn your humidistat off.
- Locate the damper. It could be either A) a knob with a summer/winter setting, or, B) a piece of metal that covers the duct opening.
- Consult the manual. If you’re not sure about your damper, consult your manual.
- Adjust the humidistat. The humidistat is usually on the ductwork above the humidifier. It has a dial that you can adjust between 0-50%. Turn it off if possible or switch it to 0 for the summer months.
- Optional: If the water valve for the humidifier is accessible, you can shut the valve off as well. If you have an older valve that is rusty, it may be best to leave it alone.
Note: This is also always a good time to inspect the humidifier pad. If it looks discoloured or mouldy, change it. Clean out the humidifier and ensure it’s ready for the fall before shutting it down.
Make the Switch from Winter to Summer Mode
Beyond switching off your humidifier, there are some other steps you need to take to get your HVAC systems ready for the summer season. You can read our article about how to get your AC summer ready.
