Ductwork and Duct Cleaning Services in Rehoboth, DE

Ventilation systems can often play a huge role in indoor air quality. It is necessary to have all of your ductwork inspected routinely to ensure that your home is circulating clean air. If your ducts have been operating for some time without inspection, they may be circulating odors, dust and other contaminates into your air. Contact First Class HVAC today and we’ll have a certified technician inspect all your ductwork and provide you with a recommended course of action.

The benefits of servicing your ductwork include:

  • Restore energy efficiency
  • Eliminate odors
  • Reduce the potential for mold growth

When air ducts contain holes and leaks, not only do harmful gases enter, but also heated or cooled air escapes from the ducts. This is why the central air system may not feel like it is working as well as it first did.

Apart from sealing your ducts and repairing those holes and leaks in your ductwork, another key step in preventing heat loss is to insulate the ducts. It is important you find an HVAC company will take the proper measures to do so. Our ducts are insulated with proper insulation to help deliver the air comfort you request. First Class HVAC is the go-to company for all your ductwork needs!

Rehoboth Beach Geothermal Systems

A geothermal heat pump or ground source heat pump (GSHP) is a central heating and/or cooling system that transfers heat to or from the ground.

It uses the earth as a heat source (in the winter) or a heat sink (in the summer). This design takes advantage of the moderate temperatures in the ground to boost efficiency and reduce the operational costs of heating and cooling systems, and may be combined with solar heating to form a geosolar system with even greater efficiency.

Here at First Class HVAC we repair, maintain and install Geothermal heating and cooling systems for businesses and residents of Rehoboth and surrounding areas. Call us today to find out how a geothermal system can be installed into your home or business.
