Simplify Your Spring Cleaning With This Thermostat Trick

February 21, 2018

Does the promise of upcoming spring weather have you in a cleaning frenzy?

If so, we’ll show you a pretty cool trick that makes your thermostat clean for you.

In fact, all you have to do is switch your thermostat fan setting from AUTO to ON once you start dusting, vacuuming or sweeping.

On Vs Auto

We’ll explain how this fan setting helps you keep your home clean...

The “ON” fan setting: Your personal duster

When you switch your thermostat fan setting to ON right before cleaning, you basically turn your AC system into an automated duster that can prevent dust from settling on surfaces in your home.

We’ll explain…

The difference between ON and AUTO

Normally, your thermostat fan setting should be set to AUTO. The AUTO setting means that your AC fan doesn’t run unless the AC is actually going through a cooling cycle (a cooling cycle usually only lasts for 10 minutes and repeats about 1–2 times an hour).

We suggest keeping your thermostat fan setting to AUTO at all times—EXCEPT for when you’re cleaning.

Why? Well, when your thermostat fan is set to ON (instead of AUTO), it means your fan is constantly sucking air into the system—which is exactly what you want when you’re cleaning.

You see, as you sweep, dust or vacuum, you’re kicking dirt and dust into the air. And if your AC fan is running, it constantly sucks in that dirty air and pushes it through the AC filter, where the dirt and dust gets trapped. (Instead of floating around and eventually landing on other surfaces in your home, which is what happens when your fan is set to AUTO).

Your AC blower pulls in air from your home, filters out the dirt/dust then pushes clean air out.

But we suggest that you use this newfound cleaning power sparingly.

That’s because keeping the fan set to ON for long amounts of time results in:

  • Higher energy bills

  • High indoor humidity levels

Ready for pro-level cleaning? Upgrade your filter

Here’s the thing: Most homeowners are using the most basic air filter out there: a fiberglass low-MERV filter (more on what “MERV” is later).

The problem with this kind of filter is that it can really only trap large contaminants—like dirt and dust.

But there are so many other air contaminants floating around your home, including:

  • Mold

  • Bacteria

  • Allergens

  • Smog particles

  • Smoke/tobacco smoke particles

So how do you capture all of these smaller air contaminants? By upgrading to at least a MERV 8 filter.

So what’s “MERV”? Well, MERV is how we rate a filter’s ability to capture contaminants. The higher the MERV, the smaller the contaminants the filter catches. MERV ratings can get as high as 20+ (basic fiberglass filters are usually 1-4 MERV).

Not sure how high of a MERV rating you need for your home’s filter? Just check out our blog, “Home Air Filters: A Simple Buyer’s Guide”.
