What Is Ductwork?

The duct or ductwork refers to the sheet metal or tubes that’s transfers the cool or warm air throughout your home or office. It can be made from metal or insulated flexible tubes.


Why Is My Ductwork Important?

Without ducts a traditional air conditioning & heating system will not be able to transfer the cold or hot air around your home. Most homes that were built after 1985 have flexible duct work that was usually made of gray plastic like material on the outer shell. Newer ductwork will have a silver material that looks similar to tin foil. Some older homes that only have a heating system will have metal ducts that are wrapped in asbestos.

Your ductwork is more important than the air conditioning and heating equipment. That’s because without a way for your cooling system to removing the heat from inside on hot days your home will never cool down, this is where ducts come in. Just any old duct won’t do though, you will also need to have the right size and types of ducts to efficiently supply cool air to each room.

Most existing air conditioning and heating systems can improve the performance by properly fixing or replacing the ductwork before replacing the exiting equipment.


How Do I Know If I Have A Problem?

Hot and cold spots in the home is the number one problem you will notice with incorrect sized or leaky air ducts.

High utility bills usually go hand and hand with bad ductwork in the home, if you have a relatively newer unit that’s less than 10 years. If your heating and cooling your attic, you’re wasting energy all year long. Worst if your sucking in air attic your breathing in dirty dusty air. Also, you will be cooling the hot air from summer heat.

Dirty air vents are a big sign that you have duct issues, it can mean that your blowing dirty air from the attic or you have an air leak behind the vent itself.



What Does Your Ductwork Do?

• Your ducts move air from the furnace or air conditioning to each room where there is a vent.
• Without ducts, your air would just blow into the attic or your closet and not into individual rooms.

Why Your Ductwork Is Important
Your ductwork is important because it moves the air from your HVAC system to your rooms. The installation of the ductwork keeps the cold air in and the hot attic air out in the summer and keeps hot air in and cold air out in the winter.

After years of struggling with an HVAC system that was not powerful enough to cool or heat my house, I decided to upgrade the whole system in May 2019. The job included relocating the furnace unit from my hallway closet to the attic, as well as... relocating the condenser unit to my backyard to be in compliance with city code. I've had the new system for almost a year, so I am writing this review to say that Angel and his Comfort Time team were really a pleasure to work with. Now I have an energy efficient system that is the right size for my house, and it keeps the whole house cool/warm and comfortable. Plus my utility bill over last summer was lower because I didn't have to run the air all day just to try to keep the house cool. Angel and his team were punctual, left the workspace clean every evening, and answered all my questions as we went along in the process. I really appreciated their attention to detail and responsiveness. I have had no issues with the HVAC, and I am very pleased with my decision to go with Comfort Time Heating & Cooling. They are top notch in my book.read more
