Ducted Heat Pumps


In Canadian residences sheet metal ducting is standard practice. Other common ducted systems may use flexible piping, or it may be a mix of flex and hard-pipe. These heating systems are very common in Canada. Duct work typically runs through the entire building to provide air to each room via a duct.

Is all ducting equal? NO! Inadequate ducting causes major problems when a heat pump is added. The heat pump requires a specific minimum air volume across the indoor coil when it runs. There are several steps servicexcel takes to make sure your ducting is correct.



Zoning is a wonderful option for precise temperature control in different areas of your house. Zone systems have a thermostat for each "zone". This means you can set different areas to different temperatures off 1 ducting system. This requires mechanical dampers, control wiring and a zone panel






Turning Vanes

Square corners are bad for airflow. Where its necessary to use a square return we can add turning vanes to reduce pressure drop and smooth airflow - which also contributes to sound dampening.






Acoustic Lining -

By adding acoustic lining in the return and supply ducting we can dampen noise from travelling through the ducts. This works great at reducing noise from the air handler that might otherwise bounce down the sheet metal.






Mastic Sealing -

To prevent air leakage which can be a serious problem - especially in unheated spaces - we use high velocity duct sealant as required to prevent losses.






Duct Sizing -

We design very quiet ducting using .1" static for supply and .05" static for return - it means your system will be quiet since there will be less static pressure on your ducting. We make all the necessary calculations and by taking a whole-system approach we can make upgrade recommendations based on what is required for a problem-free system.
