Hot or Cold Rooms are a Common Problem with a Simple Solution:

People struggling with high temperature variations between rooms or floors might not realize most of their conditioned air is escaping through duct leaks instead of flowing into their living space! Leaks in your ductwork allow cooled or heated air to escape into your attic, basement, crawlspace or even into your walls.


Your Hot or Cold Rooms may be caused by Duct Leaks

Do you notice little or no air flowing from your registers?

Your HVAC system is using energy to push conditioned air through your ductwork and into your living spaces. When your duct system contains leaks this conditioned air is actually pushed into your attic, crawlspace, or basement.

Sealing your ductworks will allow your system to properly heat and cool your home by keeping conditioned air where you want it.


Lower Your Energy Bills:

Over 90% of existing buildings located throughout North America have air duct systems that contain small holes and cracks that reduce the level of comfort and increase heating and cooling costs.

On average, 30 cents of every $1 spent on heating and cooling never makes it to your living spaces because it is leaking out of your ductwork!

Your High Utility Bills may be caused by Duct Leaks

Does your HVAC system run constantly? Do you notice higher than expected utility bills?

Duct leaks are caused by a variety of factors including the age of the dwelling, type of construction, type of ductwork and local building codes.

Repairing and patching leaks in HVAC duct systems saves cooling, heating, and fan energy. In air-based systems, ducts deliver all of the heating and cooling to conditioned spaces. Any duct leakage translates into extra air that must be supplied so sufficient heating or cooling reaches the conditioned space.  This not only increases effective heating and cooling loads, it also increases fan energy due to increased flow and/or run time.

Sealing duct leaks reduces the amount of heated or cooled air the supply fan must handle to deliver the same amount of air to the conditioned space.
