Old ducts can waste up to 40% of your system's efficiency
Ductwork needs attention just like any other system in your home. Poorly maintained ducts keep heated and cooled air from reaching your rooms and can cut efficiency by as much as 40 percent.
Older systems also leak and crack with age, and sometimes whole sections of the duct and vent system need replacing. We'll give you an honest, accurate assessment of your options.

What our customers say
With 5-star ratings and reviews on Google and Yelp, you can breathe easy knowing you're in good hands.
“My house is very old and has many holes that rats can get in. They carefully sealed every possible hole. They replaced the ducts and insulations. After the work, they cleaned the floor to make sure that the grime is gone. He turned on the furnace again and made sure that every duct is working correctly. I am totally satisfied with the work. And the bill comes in the same as the estimation.”
“Tommy came over to my house on time and gave very detailed inspections. He went up the attic, walked around and took detailed pictures, went to the garage to find out the routes that the rats taking from outside, and went to the crawl space to check further. He explained to me what to expect, what they cover and gave me a very very reasonable quote (much better than the first company I talked with)!”
“First Rate Service. The installation team was 'very' thorough in the removal of our very old blow in insulation. New batts into every nook and cranny. Friendly and left our home a clean site. Well priced. Top job done.”
Air Duct Replacement FAQ
Do I need to give attention to existing ductwork?
Yes. Aging ductwork needs attention like any other system. Poorly maintained ducts become inefficient, keep air from circulating and can reduce efficiency by as much as 40 percent.
What are common duct repairs?
Repairing parts of a system, like the air distribution unit or individual vents, is common over the life of a home. Small leaks can be sealed with mastic, and larger holes patched with sheet metal and mastic.
How do I know when it's time to replace?
When sealing and patching aren't enough, when problem areas are hard to reach or too numerous, or in older homes where materials have broken down, full replacement is usually the better investment.
Can you replace ducts and insulation at the same time?
Yes, and it's often the best time to do it, since the attic is already open and clean.
