Indoor Air Quality

Between work and home life, the average person spends about 90% of their time indoors! Indoor air can be 2 to 5 times more polluted than outside air. In fact, the Environmental Protection Agency ranked indoor air quality as a top 5 environmental danger.

A well-insulated home can help with your energy bills by keeping a constant temperature, but that also leads to the same air being recycled through your home each time you run your air conditioner or furnace. Be sure you have proper filtration in place to prevent allergens and bacteria from circulating around your air.

Environmental Systems Associates can help you breathe easy. Call us today at 410-381-7991 and we can put together a plan for your home!

Humidifiers and Dehumidifiers

The comfort of your home not only depends on the air temperature but also the amount of moisture in the air.

Cold weather typically means dry, uncomfortable air. Dry air can cause respiratory problems as well as damage wooden furniture. Whole home humidifiers emit water vapor to increase the humidity in your home.

On the other hand, hot weather can mean thick, humid air. This can lead to condensation on your windows, mold spots on walls or ceilings, blistering paint or peeling wallpaper, just to list a few issues. A whole home dehumidifier removes excess moisture from the air in your home.

Humidifiers can improve your indoor air quality as well as positively impact the overall health of your family and health of your home. Controlling the humidity in your home will help protect not only your respiratory system but also your wood floors, furniture and artwork.

Let the professionals at Environmental Systems Associates help you decide what’s best for your home! Call us at 410-381-7991 or request service online today.

“Hello. A big thank you and shout out to Scott, April and Alex for their help this week! I appreciate the time that Scott took to speak with me on the phone about the switch on the air handler and how the plastic covering gets dirty. It was great that April was able to schedule a technician to come out so quickly. And, Alex thoroughly investigated, cleaned the plastic covering and took photos to show that there wasn’t dirt/mold in other parts of the unit. Thanks again for the prompt and professional service.”
