Taking steps to improve indoor air quality can help create a better indoor environment in your home or office, reduce irritants that can impact your health, and maximize your comfort. 

Get in touch with us to discuss your indoor air quality improvement options today! 

We offer indoor air quality services to keep you healthy and comfortable including:

  • Air filter replacement
  • Whole-house air purifier installation
  • Whole-house humidifier installation

Whole-House Air Purifier Installation

According to the EPA, indoor air can be much more polluted than the air outside (source: EPA). This is because particulates such as dust, pet dander, household cleaning products, and emissions from fireplaces and stoves accumulate in the vents of your home and contaminate the air being circulated. Having this contaminated air circulating through your home can trigger allergies, asthma, and other health issues.

While a standalone air purifier can help improve indoor air quality in a small space, it can’t cover your whole house. In-duct air purifiers can help improve indoor air quality in your entire house helping keep everyone healthy and your home odor-free.

We have a range of whole-house air purifier products that we install for our Northern, Virginia customers from AprilAire & Aerus Enterprise Solutions (AES). Watch the video to learn how the Air Scrubber by Aerus works.

Whole-House Humidifier Installation

If you’re sensitive to dry air or would like to add an extra layer of comfort to your home, you should consider having a whole-house humidifier installed. Whole-house humidifiers allow you to control the humidity in your home and set it to your desired level with your thermostat. Every home is different but, the ideal humidity level for your home ranges from 30% – 50% humidity.

Beyond extra comfort and control, there are a host of other benefits of whole-house humidifiers such as:

  • Preventing damage to furniture and wood flooring caused by low humidity levels
  • Preventing the growth of mold and fungi
  • Contributing to a healthier living environment

Ask our technicians about installing a whole-house humidifier in your home and experience a new level of comfort and control.
