General Tips for Making Your Home More Comfortable

In addition to calibrating your ecobee thermostat to control humidity, there are a few other things you can do to make your home more comfortable.

Here are a few tips:

Invest in a Dedicated Dehumidifier

If you live in a particularly humid climate or have many people living in your home, you might want to consider investing in a dedicated dehumidifier.

Dedicated dehumidifiers are designed to remove moisture from the air and can be used in conjunction with your ecobee thermostat to improve the comfort of your home further.

Here are a few tips for choosing the right dehumidifier for your needs:

  • Choose a dehumidifier with a capacity that’s appropriate for the size of your space.
  • Check the dehumidifier’s review before making your purchase.
  • Make sure the dehumidifier you choose is Energy Star certified.

For starters, check out this Honeywell TP30WKN Energy Star Dehumidifier from It’s Energy Star certified, easy to use and maintain, and powerful, making it a great option for most people.

Use Exhaust Fans in a Humid Room

Another way to remove moisture from the air and improve the comfort of your home is to use exhaust fans in humid rooms.

Exhaust fans help to circulate the air and remove moisture from the room, making it more comfortable.

Here are a few tips for using exhaust fans:

  • Use exhaust fans in the kitchen and bathroom to remove moisture from the air.
  • Make sure the exhaust fan is vented to the outside of your home.
  • Turn on the exhaust fan when you’re cooking or showering, and leave it on for at least 30 minutes after you’re done.

Keep Your Home Clean and Pest-Free

A clean and pest-free home is a comfortable home. Dust mites, for example, thrive in humid environments and can cause allergic reactions in some people. Likewise, cockroaches and other pests are attracted to moisture and can make your home uncomfortable.

Here are a few tips for keeping your home clean and pest-free:

  • Vacuum regularly with a HEPA filter vacuum cleaner.
  • Wash bedding on a hot cycle once a week.
  • Keep food sealed and stored properly.
  • Fix any leaks or standing water in your home.

Use a Humidifier in a Dry Climate

If you live in a dry climate, you might want to consider using a humidifier. Humidifiers help to add moisture to the air, making it more comfortable. A humidifier can also help reduce static electricity and make your home feel warmer.

There are a few things to keep in mind when using a humidifier, though:

  • Be sure to clean the unit regularly. Otherwise, it can become a breeding ground for mold and bacteria.
  • Don’t overdo it. Too much moisture in the air can be just as uncomfortable as too little.
  • Ensure that the humidifier is properly vented.

Place Plants Around Your Home

Plants not only add beauty to your home but can also help to improve the air quality. Plants help filter the air and remove pollutants, making breathing more comfortable.

Here are a few tips for choosing plants for your home:

  • Choose plants that are appropriate for the climate in which you live: desert plants for dry climates, tropical plants for humid climates.
  • Choose plants that are appropriate for the amount of light in your home: low-light plants for shady spaces and high-light plants for sunny areas.
  • Avoid plants that are known to be poisonous: That way, you don’t have to worry about your kids or pets getting sick.


Creating a comfortable environment in your home is important for your health and well-being. So take the time to calibrate your ecobee thermostat correctly and implement other comfort-enhancing measures.

Doing so will help ensure that your home remains comfortable year-round—no matter what Mother Nature throws your way!
