Ductwork Services
Professional duct design, installation, sealing, and replacement to maximize your HVAC system’s performance.
The Importance of Proper Ductwork
Well-designed, sealed and insulated ducts deliver heated or cooled air evenly through your home. Leaks or poor sizing can waste energy and leave rooms uncomfortable.
Our Ductwork Services
Comprehensive duct solutions for new construction, renovations, and existing homes.
📐
Duct System Design
We size ducts and registers for the airflow each room needs, using your home’s layout and equipment requirements.
🛠️
Duct Installation
We install and seal duct connections, insulate runs where needed and place registers for balanced airflow.
🔒
Duct Sealing
We locate duct leaks with inspection and testing, then seal them with approved materials to reduce wasted air.
🔄
Duct Replacement
Crushed, disconnected or badly damaged ducts may need replacement. We design and install new runs to restore airflow.
Signs of Ductwork Problems
Your ductwork may be costing you comfort and money if you notice any of these warning signs.
🌡️
Uneven Temperatures Between Rooms
Hot and cold spots can come from duct leaks, disconnections or undersized runs. We can measure airflow and find the cause.
📈
Unusually High Energy Bills
Leaky or poorly insulated ducts can send conditioned air into attics or crawlspaces, making your system work harder.
💨
Weak or No Airflow from Registers
Weak airflow at a register may mean a duct is kinked, crushed, blocked or disconnected.
🌫️
Excessive Dust in Your Home
Leaky return ducts can draw dust and debris into the air stream. Sealing the leaks may help.
🔊
Strange Noises from Ducts
Rattling, popping or whistling can point to loose ducts, air leaks or airflow restrictions. We can identify the source.
👃
Musty or Stale Odors
Musty odors while the system runs may indicate moisture or contamination in the ducts. Arrange an inspection promptly.
Duct Materials: Making the Right Choice
The material used for your ductwork impacts performance, longevity, air quality, and cost. Here’s what you need to know about each option.
Sheet Metal Ducts
Sheet metal is durable and offers smooth airflow. It usually costs more to install and may need added insulation.
Flexible Duct (Flex Duct)
Flexible duct is useful for shorter runs and often costs less to install. It must be supported and stretched to avoid airflow restrictions.
Fiberglass Duct Board
Fiberglass duct board includes insulation and absorbs sound. Its interior is harder to clean than smooth metal.
Duct Material Comparison
Compare the key characteristics of common residential duct materials.
| Characteristic | Sheet Metal | Flexible Duct | Fiberglass Board |
|---|---|---|---|
| Durability | Excellent — 30+ years | Good — 15-25 years | Good — 15-20 years |
| Airflow Performance | Best (smooth interior) | Good (when fully stretched) | Good (smooth interior) |
| Insulation | External insulation required | Built-in insulation | Built-in insulation |
| Sound | Can transmit noise | Good sound dampening | Excellent sound absorption |
| Mold Resistance | Excellent | Good | Fair (porous surface) |
| Installation Cost | Higher | Lower | Moderate |
| Cleanability | Easy to clean | Difficult to clean | Difficult to clean |
| Best Use | Main trunks, exposed runs | Branch runs, tight spaces | Commercial, specialty |
HVAC Zoning Systems
Zoning uses separate thermostats and duct dampers to control temperatures in different areas of a home. It can help with hot and cold rooms, especially in multi-story homes.
Benefits
- Control each area independently
- Condition fewer unused spaces
Before Installing
- Check duct sizing and airflow
- Allow for added controls and cost
Design matters: We assess your equipment and ducts before recommending zoning.
Our Ductwork Process
Whether you need a complete new duct system or targeted repairs, our approach is thorough and professional.
🔍
Inspection & Assessment
We inspect duct condition, sizing, insulation, leaks and airflow to identify what is limiting performance.
📐
Design & Recommendation
We explain the findings, recommend repair or replacement options and provide clear pricing.
🛠️
Professional Execution
We fasten and seal connections, insulate ducts where needed and check airflow at the registers.
📋
Verification & Documentation
We test airflow and leakage after the work and provide a record of the results.
