Ductwork & Ventilation Services

Ductwork & Ventilation systems are essential for maintaining efficient airflow, indoor air quality, and consistent comfort throughout your home or business. At SumZero, we provide expert custom solutions in Massachusetts to optimize duct design, installation, and modifications for peak performance.

Ductwork Installation and Replacement

Upgrading your duct system can make a noticeable difference in how evenly and efficiently your home stays comfortable year-round. Whether you're building a new space or replacing aging components, the right installation is key to long-term performance.

Duct System Redesign for Better Efficiency

Older ducts often restrict airflow or leak air, causing higher energy bills and uneven temperatures. A full duct system redesign corrects layout issues, removes bottlenecks, and ensures each room gets the proper airflow.

  • Replace old or damaged ducts to remove leaks
  • Reroute duct lines to improve airflow paths
  • Resize ducts for proper pressure balance
"Up to 30% of conditioned air can be lost through leaks or poorly connected ducts—leading to higher bills and reduced comfort."

HVAC Airflow Optimization During Installation

When installing new ductwork, we tailor every layout to your home’s specific needs. HVAC airflow optimization ensures the system doesn’t overwork, saving you both energy and money.

  • Calculate room-by-room airflow needs
  • Position vents for balanced temperature control
  • Seal joints and connections to prevent leaks

Custom Ductwork Solutions and Ventilation Modifications

Precision-designed duct systems are essential for reliable temperature control and clean indoor air. When off-the-shelf options fall short, our custom ductwork solutions fill the gap with thoughtful, made-to-fit designs.

Ductwork Modification Services for Older Homes

Homes with outdated ductwork benefit greatly from ductwork modification services. We enhance and retrofit ducts to work better with modern HVAC systems by:

  • Adjusting duct size for newer equipment
  • Sealing and insulating old duct lines
  • Adding returns for better circulation

Ventilation Experts Create Healthier Airflow

Boosting indoor air quality often starts in your duct system. As local ventilation experts, we can modify existing layouts for healthier airflow using methods approved by Mass Save®.

  • Add fresh air intakes where needed
  • Improve kitchen and bathroom exhaust
  • Install filters that trap allergens and dust

What Local Homeowners Are Saying

See how SumZero has helped local homeowners stay comfortable year-round with energy-efficient heat pump solutions.

UPDATE: It's been about 3 months since my new heat pump and gas furnace were installed and things have been humming along, moving seamlessly from cooling to heating. When the temps dropped close to 20 a couple of weeks ago though, the heat pump began to work a little harder and longer at squeezing heat from the frigid air (as we knew it would). So I looked to boost the BTU's by firing up the furnace. Though the blower came on, there was no gas, no flame. A check of the gas line valve and the circuit breaker all looked good. Working different modes on the thermostat I tried multiple times, but the furnace remained cold. I gave SumZero customer support a call first thing Monday morning and got voicemail. Though the message proclaimed my "call was important," my heart sank a little wondering WHEN I would hear back. But Lara cheerfully got back to me within the hour and said she would have a technician by the name of Dan Jameson out to the house between 1:00 and 3:00. Dan arrived a little before 2:30 with the same sunny disposition that seems to be part of the culture at SumZero. He invited me to shadow him and learn a little bit more about my HVAC system while he checked it out. He quickly discovered that an internal gas valve was in the off position, something town inspectors like to see when heating is not required (though it really isn't necessary). Needless to say, the furnace began working like a champ. Dan also took time to check the filter, the heat pump, and program the thermostat, all the while answering my questions and giving me valuable pointers as well. Now when the weather drops below freezing, the heating automatically kicks over to the gas furnace. Should any other questions come up, Dan made a point of saying to be sure to call and, if need be, they'd be happy to come out to the house to explain. Once again, everything is working as it should. And SumZero rocks! Though you try to get some idea of who you are hiring through online reviews and asking the right questions (if you even know what questions to ask), a lot of blind trust goes into choosing a contractor - trust that you'll get what was agreed to, on time, in working order, and at the right price.  I'm happy to say that SumZero checks all the boxes - and then some.  From sales rep Paul Jameson to Sarai and Lara in the office, to Wanderson and his installation team led by Paulo, ALL were professional, knowledgeable, super polite, and patient - exemplars of what customer service used to be.  I am very, very happy with my whole house heat pump and additional duct work that was extended into a recent addition.  An added bonus is that they will help with the submission of paperwork for the Mass Save rebate.  For family and friends contemplating similar work in their homes, I'll definitely point them SumZero's way.  Well done!
