Combat Charleston’s High Humidity for a Healthier, More Comfortable Home  

The Greater Charleston area is no stranger to intense humidity, especially during the long summer months. While air conditioning helps to cool your home, it’s not always enough to control excessive moisture levels—and that’s where a whole-home dehumidifier can make all the difference.  

At Carney & Son 72 Degrees, we specialize in whole-home dehumidifier installation and repair to help homeowners protect their HVAC systems, improve indoor air quality, and enhance comfort.

Why Is Dehumidification So Important in Charleston?

With Charleston’s coastal climate, humidity levels can soar well above 80% during much of the year. While some moisture in the air is normal, too much can lead to:  

  • Increased strain on your HVAC system – High humidity forces your AC to work harder, leading to higher energy bills and frequent breakdowns.  
  • Mold & mildew growth – Damp conditions create a perfect breeding ground for mold, which can lead to health issues and costly home damage.  
  • Dust mites & allergens – Excess moisture fosters allergen growth, aggravating allergies and respiratory conditions.  
  • Sticky, uncomfortable indoor air – Even if your home is cool, high humidity can make it feel stuffy and unpleasant.  

A whole-home dehumidification system eliminates excess moisture before it becomes a problem, helping your HVAC system run more efficiently while keeping your home’s air cleaner, healthier, and more comfortable.

Frequently Asked Questions About Ducted Mini-Split Systems

What is a ducted mini-split system?

A ducted mini-split system is an HVAC solution that combines an outdoor unit with a concealed indoor unit connected to ductwork. This setup allows for efficient heating and cooling of multiple rooms while keeping the indoor units hidden from view.

How does a ducted mini-split differ from a ductless mini-split?

While both systems consist of an outdoor compressor and indoor air-handling units, a ducted mini-split uses hidden ducts to distribute air, providing a seamless look. In contrast, ductless systems have visible wall-mounted units in each room.

Can a ducted mini-split system be installed in an existing home?

Yes, ducted mini-split systems are versatile and can be retrofitted into existing homes. Our technicians assess your home’s layout to design a system that meets your specific needs.

Are ducted mini-splits energy-efficient?

Absolutely. Ducted mini-splits utilize advanced inverter technology, allowing for precise temperature control and reduced energy consumption compared to traditional HVAC systems.

How often should I maintain my ducted mini-split system?

Regular maintenance is crucial for optimal performance. We recommend scheduling professional maintenance at least twice a year to ensure your system operates efficiently and to extend its lifespan.

What are the benefits of zoning with a ducted mini-split system?

Zoning allows you to set different temperatures for various areas in your home, enhancing comfort and potentially reducing energy costs by conditioning only occupied spaces.

How long does the installation process take?

Installation time varies based on the complexity of the project, but most ducted mini-split systems can be installed within a few days. Our team works efficiently to minimize disruption to your daily routine.

Are there financing options available for ducted mini-split systems?

Yes, we offer various financing options through GreenSky with competitive rates to make your investment more manageable.

What should I do if my ducted mini-split system isn't working properly?

If you experience issues, contact our team immediately. Our certified technicians will diagnose and resolve the problem promptly to restore your comfort.
