Air Filtration and Air Purifiers

Did you know your HVAC air filter does not protect or improve your indoor air quality? It certainly does not hurt your home's indoor air quality. However, its primary purpose is to protect your HVAC systems themselves from dust, dirt, and other debris that can get inside and damage the components. For comprehensive indoor air quality in Johns Creek, you'll want to look into whole-house air filtration and purification. Dayco Systems provides installation and services for all types of these systems, including UV air purifiers for harmful bacteria!

Air Duct
Testing and Sealing

Ductwork breaches can account for up to 30% of your conditioned air being lost. It seeps out into unoccupied spaces like your attic or behind your drywall, and never actually reaches the rooms that the conditioned air is intended for. This means that you are paying to heat or cool your home, but a portion of your home isn't receiving that air, so you're paying more for less comfort. As a trusted Johns Creek air duct testing and sealing company, we'll test your ducts and find out where your opportunities are. From there we can assess where professional duct sealing can help.
