Duct Work


Most air conditioning and heating systems require some form of duct work to channel or direct the air to places in the dwelling where the conditioned air is needed. There are many types of duct work available and often times the duct work can make a big difference in your utility bills. For that reason, it is important that the duct work is installed correctly by qualified installation technicians. A poor installation job will result in poor performance, bad air flow, leaky duct systems, and higher than usual utility bills. Another important factor in the installation process is to make sure the duct work is sized properly. Oversizing systems cost more and does not maintain the desired air flow and undersized duct work causes the system to strain mechanically and can be noisy. It is important that you have qualified people design and install your system from start to finish so that you get the best and highest performing duct work system money can buy. It is also critical that the air conditioning ductwork system be designed for the air conditioning load.
