Venting & Ductwork


Maintenance, Repair, or Installation
Proper installation means that the ductwork delivers the right amount of air to each room while also meeting the manufacturer’s specifications. If you are losing heat, it’s possible that you have air leakage in your duct system. We can make sure that all your ductwork is properly sealed at all joints and seams and entry spots to heated locations.

Air conditioning and heating systems need adequate ventilation to work properly. Some installations require properly-insulated lines to ensure maximum efficiency. Our HVAC team is here to help!
Exhaust fans/vents often pull out the cool air in an air-conditioned room when make-up air is not supplied properly. Ductwork is composed of two parts: supply and return. The supply duct is attached to the outflow of the new system, delivering air to each zone in an office. The amount of air reaching each zone is determined by the size of supply ductwork connecting it to your system. We will help you determine the correct size of all the supply ductwork. The second part of the ductwork, the return duct, attaches to the inlet of the new system and draws air out of the spaces to be heated or cooled. Attached to the return duct is the filter. The filter should be placed as near to the furnace or air handler as possible. Ductwork must be properly sized to distribute the proper amount of air to each room evenly.
One of the most important parts of proper installation is ensuring that the ductwork can deliver adequate airflow to maintain comfort, and meet the manufacturers’ specifications.
Air leakage from ducts can be one of the largest sources of heat loss. Ducts need to be sealed where sections are joined, along the seams in individual duct sections, and where the duct penetrates from unheated to heated locations.
