Sizing and installing your ductwork right

Design, Installation, and Proper Insulation of Your Ducting

Meeting Energy Star Standards for Duct Design

  • Design high quality duct systems that are properly balanced
  • Meet Energy Star duct sizing requirements for air quality, safety, and comfort
  • Proper insulation of ductwork inside and outside the conditioned space
  • Duct sealing with foil-reinforced tape specifically made for duct sealing
  • Installation of whole-house air make-up systems; such as ERV’s and HRV’s
  • We are also gas licensed in NH to install and service gas furnace systems
  • Residential duct design and calculations are performed by professional HVAC technicians and meet quality standards set by Energy Star.

Certified QA Energy Star HVAC Contractor

To get your home Energy Star Certified, you need a Certified QA Energy Star HVAC contractor. If we install the sheet metal for the job, we have that certification and can be QA for the project. We do many Energy Star Homes and will partner with your contractor to certify your home.

Ductwork is Sized for Your Home

The size of your ducting directly relates to the air quality in your home. If air ducts are too large, that can allow excess noise to travel through the empty space to other rooms in your home and not allow enough airflow to the areas the heat is supposed to travel to. Ducts that are too small can also have a noisy effect, delivering too much air through a confined space and creating a whistling effect in the ductwork.  Both of these scenarios will not heat and cool rooms properly and will leave a homeowner not satisfied with the HVAC system installation.

Installing Ducting in Energy Efficient Locations

Whenever possible, ductwork should be contained within the conditioned air space (in the heated/cooled area) of your home. This promotes energy efficient transfer of conditioned air to the places that need it, minimizing loss along the way. Ensuring air-tight ductwork is an essential step in building an efficient HVAC system.

Sealing Ducting for Improved Comfort and Air Quality

Leaky ducts can reduce your heating and cooling system efficiency by up to 20 percent. Sealing ductwork reduces conductive heat losses, saving you money on your energy bill. Duct sealing also limits the amount of dirt, dust, and impurities that can negatively affect indoor air quality.

Common Duct Problems

  • Leaky, torn, disconnected ducts
  • Poorly sealed registers and grills
  • Leaks at furnace and filter slot
  • Kinks in flexible ductwork reducing airflow

 

Possible Signs of Leaky, Poorly Insulated, or Inefficient Ducts:

  • High summer and winter utility bills
  • Rooms in your home that are difficult to heat and cool
  • Rooms that feel stuffy
  • Ducting located in an attic, unfinished basement, crawlspace, or the garage
  • Flexible ductwork that is kinked or tangled
