Their $99 promotion — main drain cleaning + camera inspection — is a great deal. The guys who did the work were very systematic, surveying the drain pipe both before and after cleaning it out, and explaining what they found very clearly. They followed up with a proposal for fixing the pipe. I will of course bid out the repair, and I have no information about how efficient and economical they are for doing this work.

Living on the Cape finding a reliable service company can be difficult. GEM is now my go to for HVAC and plumbing service.
> Five stars for Davontay V. He came out to our Foxborough building for a no-heat call, found a loose heat-call wire in minutes that the previous tech had walked right past, reconnected it, and there was no charge for the visit. Professional, fast, and honest. He's our requested tech from now on. Additionally, Davontay also put the lock cover back on, locked up every door, shut off the lights, and took care of a few small cleanup items that weren't part of his job — all without being asked. Great job!

Signs It’s Time to Install New Ductwork

Ductwork often goes unnoticed until comfort problems start to show up. If your home isn’t heating or cooling the way it should, your duct system may be part of the issue.

Look for the following signs:

If some rooms are consistently hotter or colder than others, your ductwork may be poorly designed or deteriorating. New ductwork helps distribute air evenly for balanced comfort in every space.

Leaky or inefficient ducts can waste a significant amount of energy as conditioned air escapes before reaching your rooms. Replacing old ductwork helps your heating and cooling system work more efficiently and can lower monthly energy costs.

If you notice weak airflow from vents or increased dust around your home, damaged or outdated ducts may be to blame. New ductwork improves airflow and helps support cleaner indoor air.

Ducts that are crushed, disconnected, rusted, or more than 15–20 years old may no longer perform effectively. Installing new ductwork restores reliability and reduces the risk of ongoing issues.

Benefits of Installing New Ductwork

New ductwork can dramatically improve how your HVAC system performs throughout your home. When air flows efficiently and evenly, comfort, efficiency, and reliability all improve.

Homeowners often notice these benefits after new ductwork is installed:

Properly designed ductwork delivers balanced airflow to every room. This helps eliminate hot and cold spots and keeps your home comfortable year-round.

Sealed, properly sized ducts reduce air loss and help your system work less to maintain comfort. That efficiency can lead to lower energy bills and less strain on your HVAC equipment.

New ductwork helps reduce the buildup of dust, debris, and contaminants that can circulate through aging ducts. Cleaner airflow supports a healthier indoor environment for your family.

You may wonder how to install ductwork in existing walls or infrastructure. When you work with a professional HVAC team to install ductwork in your home or business, there are several key steps. Our team follows this process:

Testing and balancing: The final step is to test the system to confirm there are no leaks and that airflow is balanced for optimal performance.

Planning: Our HVAC team will assess the building’s layout and design a ductwork system to ensure efficient airflow.

Cutting and fitting: We cut openings in walls, floors, or ceilings to fit the ducts. We’ll also measure and cut the duct material to the required lengths for your unique system.

Assembling and securing: The ducts are constructed using fittings and then securely fastened into place with brackets or hangers.

Sealing and insulating: Ducts are sealed with mastic or metal tape to prevent air leaks.

Connecting to HVAC system: Your ductwork is connected to your HVAC unit to guarantee proper distribution throughout your home.

Air ducts are a network of tubes that distribute heated or cooled air throughout your home. A healthy ductwork system is crucial to the proper function of your HVAC.
