Reasons to Install a Whole Home Dehumidifier

Having the right balance of moisture in your home is critical to your comfort and your health. But if you have found that your home feels excessively clammy, you have too much moisture inside your home. One of the best ways to tackle this problem is with the installation of a whole home dehumidifier. Working both in concert with your HVAC system, as well as autonomously, a whole home dehumidifier removes excess moisture from your air before it can circulate into your HVAC system. This is important because excess moisture can lead to the development of mold and mildew, rot, and provide an environment for dust mites to thrive in. Don’t let excess moisture make your home a haven for allergens and other problems – call our pros today and ask about whole house dehumidification!

Faulty Ductwork? It’s Time to Consider Duct Sealing

While duct sealing is its own separate duct service, it most certainly falls under the bigger umbrella of duct repair. What makes duct sealing so important is the benefits the service provides:

  • Better energy efficiency – faulty ductwork can account for up to one third of your home’s total air loss. Duct sealing helps you regain this lost efficiency by sealing those holes and cracks.
  • Increase the quality of your indoor air – faulty ductwork doesn’t just lose air, it also allows outside pollutants, odors and contaminants into your home. Our experts can stop this infiltration with our expert duct sealing services.
  • Reduces stress on your HVAC system – when your HVAC system loses considerable amounts of air to faulty ductwork, it compensates for this loss by working harder. This puts undue stress on the system, which can result in excessive wear and tear. We can take the stress off by professionally sealing your ductwork.
