HVAC System Ductwork and Maintenance

Your building’s heating, ventilation, and air conditioning system performs functions such as taking in room air, removing allergens, odors, moisture, dust, and smoke; supplying and circulating hot or cold air; and monitoring for a change in temperature to start and shut off the unit. Here, you will learn about HVAC ductwork, maintenance, and thermostat.


Your HVAC system uses a system of tubing called ductwork to circulate air to each room in your building. An HVAC contractor may fabricate ductwork solutions designed to your needs, such as custom metal sheet fabrication Batavia IL.

Ductwork may run above your ceiling or under your floor and comes in rectangular or spiral form. Sealing the ductwork with mastic ensures that air does not leak out of the ductwork along the duct run. Following the sealing, insulation wrapped around your ductwork keeps the air temperature inside the ductwork from being affected. Therefore, conditioned air reaches the grills in each room at the intended temperature.

Dust buildup, insects, mold, mildew, pet dander, and rodent feces, when present in your ductwork, may cause allergies or issues with your respiratory system. Periodic ductwork cleaning may help lower those attributing factors.


To help lengthen the life of your HVAC system, have your unit inspected once a year. Also, replace your filter once a month, especially if there are pets in the building. This maintenance helps remove allergens, pet dander, and dust from the air before it gets recirculated. Lint that collects on your HVAC filter may make it harder for air to reach the system. Therefore, filter replacement may also lower strain on your system.


Switch to a programmable thermostat. With this type of thermostat, you may program settings for automatic temperature adjustments on a schedule you design. To save on energy costs, you may program the system to automatically turn up or down the temperature during specific hours in the summer and winter months.
