Regularly maintaining your HVAC system is a simple and inexpensive way to improve indoor air quality and efficient heating and cooling.

Protect your HVAC ductwork by having it repaired, cleaned, and insulated correctly. Taking care of it is a simple and inexpensive way to improve indoor air quality and efficient heating and cooling. It’s essential to have HVAC maintenance performed annually.

Cleaning the HVAC Ducts

Routine vacuuming of the HVAC registers is essential, but you do not necessarily have to clean them deep inside regularly. However, there may be some situations in which you may have to get the interiors of the ducts cleaned as soon as possible. For example, if you see mold growth inside the HVAC ducts, you need to clean them to avoid health problems such as asthma, allergies, and other respiratory problems.

At times, insects and rodents may also find a way into your ducts; if you can spot any, immediately clean the vents thoroughly. During home renovations, keep the ducts adequately covered to prevent dust, asbestos, or lead paint from entering the ducts. If they do enter the ducts, have them cleaned. If you smell any unpleasant odors or other pollutants in the air or experience unexplained respiratory or skin problems, you should get the ducts cleaned.

Repairing Leaks

The ductwork can develop holes in individual pipes, or there may be poor connections between the pipes that cause leaks. The leaks can decrease the efficiency of your HVAC system by over 20% and increase greenhouse emissions. HVAC leaks may backdraft poisonous gases such as carbon monoxide into your living space. To detect any leaks, inspect the ductwork visually, and for leaks in hidden areas, switch the thermostat to “on” mode, and you will be able to feel any escaping air. Seal the leaks using a metal tape, aerosol sealant, or mastic sealant.


Proper insulation helps conserve the temperature-controlled air that your HVAC system produces. This reduces energy consumption and brings down the utility bills. To find out whether you need to insulate the ductwork, you can check the temperature difference in the air from the ducts and the one surrounding it. If the difference is considerable, then you should consider duct insulation.

There are various types of materials available for insulating ducts. They come in blanket and sleeve styles; the blanket style is better if you intend to do the job independently. It consists of foam, cotton, bubble wrap, or fiberglass. The one that contains cotton is the most eco-friendly option.
