Pickering homeowners count on Cassar Heating & Air Conditioning for honest ductwork service that’s done right the first time. We understand the unique challenges of homes in this area, from older neighbourhoods with original ductwork to newer developments that may have been rushed during construction.
Most residential ductwork in Ontario lasts 15-25 years, depending on the materials used and installation quality. Galvanized steel ducts, common in homes built before 1990, often develop rust and corrosion issues after 20 years, especially in basement installations where humidity can be higher. Flexible ductwork typically needs replacement sooner — around 10-15 years — as the inner liner can deteriorate and restrict airflow.
The harsh Ontario climate puts extra stress on ductwork through temperature swings and seasonal changes. Ducts in unconditioned spaces like crawlspaces or unfinished basements are particularly vulnerable to condensation issues that can lead to mold growth and structural damage. If your Pickering home has original ductwork from the 1980s or 1990s, it’s worth having it inspected even if it seems to be working fine.
Ductwork repair in Pickering typically ranges from $200-800 for minor issues like sealing joints or replacing a section of damaged flex duct. More extensive repairs involving main trunk lines or multiple branch repairs can run $800-1,500. Complete ductwork replacement for an average Pickering home ranges from $3,000-7,000, depending on the size of your home, accessibility, and materials chosen.
New ductwork installation for additions or new construction typically costs $1,200-2,500 per room, including proper sizing calculations and installation. However, every home is different, and costs can vary significantly based on your specific situation. At Cassar, we work with a wide range of budgets and offer financing options to make necessary ductwork repairs and replacements affordable.

Pickering’s diverse housing stock presents unique ductwork challenges. The older homes in central Pickering, many built in the 1960s and 1970s, often have original galvanized ductwork that may be undersized for modern high-efficiency furnaces and air conditioners. These systems were designed when homes were less tightly sealed and equipment was less powerful.
Newer developments like Bay Ridges and Village East typically have modern ductwork, but we sometimes see issues with builder-grade installation where corners were cut during construction. Flex duct may be over-stretched, improperly supported, or poorly connected at joints. Additionally, many Pickering homes have finished basements that make ductwork access challenging for repairs, requiring creative solutions to restore proper airflow without major renovation.
The most obvious sign of ductwork problems is uneven temperatures throughout your home — some rooms consistently too hot or cold while others are comfortable. This is especially noticeable in Pickering’s larger two-story homes where upstairs bedrooms may struggle to stay cool in summer or warm in winter. You might also notice that your furnace or air conditioner runs constantly but never seems to reach the thermostat setting.
Physical signs include unusual dust accumulation around vents, which can indicate leaks pulling in dusty air from wall cavities or the basement. Listen for whistling or rattling sounds from vents when the system runs — this often indicates loose connections or damaged ductwork. Higher than normal energy bills without explanation can also point to ductwork leaks that force your system to work harder to maintain comfort.
In basement utility rooms, look for disconnected joints, torn flex duct, or visible gaps in ductwork. Even small separations can lose significant conditioned air and create pressure imbalances that affect the entire system’s performance.
Durham Region’s humid summers and cold winters create condensation challenges that homeowners in drier climates don’t face. Ductwork in unconditioned spaces must be properly insulated to prevent condensation formation, which can lead to mold growth and structural damage. This is especially important for ducts running through crawlspaces or unheated basements.
During winter, poorly insulated ductwork loses significant heat before it reaches your living spaces, forcing your furnace to work harder and increasing energy costs. In summer, cold air conditioning ducts without proper insulation will sweat heavily, potentially causing water damage and creating ideal conditions for mold growth.
Proper ductwork isn’t just about comfort — it’s crucial for safety and indoor air quality. Leaking return ducts can pull in contaminated air from basements, crawlspaces, or even from around furnace exhaust areas, introducing carbon monoxide or other pollutants into your living space. This is why professional ductwork inspection should be part of regular HVAC maintenance.
Modern high-efficiency furnaces and air conditioners require properly sealed and sized ductwork to operate safely and efficiently. Oversized ducts cause short cycling and poor humidity control, while undersized ducts create excessive pressure that can damage equipment and reduce system lifespan. Ontario’s energy codes require ductwork to be sealed and tested in new construction, but older homes often benefit from similar upgrades to improve both safety and efficiency.
Before calling for service, try these quick checks that might restore your ductwork performance.
Make sure every supply vent in the home is fully open. Closed vents cause pressure imbalances that reduce performance and can damage equipment.
In basements and utility rooms, look for disconnected joints, torn flex duct, or visible gaps. Even small separations can lose significant conditioned air.
A blocked filter causes pressure imbalance across the entire duct system, making uneven heating and cooling worse. Replace it first before anything else.
Rooms consistently too hot or cold, or that take longer to reach temperature, indicate specific duct branches that are undersized, leaking, or poorly routed.
Unusual dust buildup around supply vents can indicate leaks pulling in unconditioned air from attic or wall cavities — a significant air quality and efficiency issue.
If none of the above restore your ductwork, it’s time for a licensed technician. David and his crew serve all of Durham Region and respond fast.
Leaking or undersized ductwork shows itself through uneven temperatures, high energy bills, and poor system performance. You’ll notice some rooms are consistently too hot or cold, your furnace or AC runs constantly but struggles to reach the thermostat setting, and you may hear whistling sounds from vents. In Pickering’s larger two-story homes, this often shows up as upstairs bedrooms that are uncomfortable while the main floor feels fine. Physically inspect visible ductwork in your basement for disconnected joints, torn flex duct, or gaps at connections.
Ductwork repair in Durham Region typically ranges from $200-800 for minor issues like sealing joints or replacing damaged sections, while more extensive repairs can run $800-1,500. Complete ductwork replacement for an average home ranges from $3,000-7,000 depending on size and complexity. However, costs vary significantly based on your specific situation, home layout, and accessibility. At Cassar, we work with a wide range of budgets, financing is available, and every job gets a free upfront quote with no obligation.

Absolutely. Damaged or leaking ductwork forces your furnace and air conditioner to work much harder to maintain comfortable temperatures, leading to higher energy bills and premature equipment failure. Leaks cause pressure imbalances that can damage blower motors and heat exchangers. Undersized ducts create excessive back-pressure that reduces system efficiency and shortens equipment lifespan. In severe cases, return duct leaks can pull in contaminated air that affects indoor air quality and safety.
Complete ductwork installation typically takes 1-3 days for an average Pickering home, depending on the size and complexity of the system. Simple ductwork repairs can often be completed in a few hours, while partial replacement of damaged sections might take a full day. New installations for home additions or major renovations require more time for proper design and installation. We provide realistic timelines upfront and work efficiently to minimize disruption to your family’s routine.
This depends on the age, condition, and design of your existing ductwork. If your ducts are relatively new (less than 15 years) with minor leaks, professional sealing might be sufficient. However, if you have original galvanized steel ducts from the 1980s or earlier, undersized ducts for modern equipment, or extensive damage, replacement is usually more cost-effective long-term. We’ll inspect your entire system and give you honest recommendations based on what makes the most sense for your situation and budget.
Hot and cold spots are often ductwork-related, especially in Pickering’s larger homes where proper airflow distribution is critical. Common causes include undersized ducts to problem areas, leaks in specific branch lines, blocked or closed vents, and poor original ductwork design. This is particularly common in older Pickering neighbourhoods where ductwork may not have been properly sized for modern high-efficiency equipment. A professional ductwork assessment can identify the specific issues causing uneven temperatures in your home.
Our primary focus is ductwork installation, repair, and replacement rather than cleaning. However, we work with trusted local duct cleaning specialists when needed and can recommend reliable companies that serve the Pickering area. Often, homeowners think they need duct cleaning when the real issue is leaking or damaged ductwork that’s pulling in dusty air from unconditioned spaces. We’ll help you determine what your system actually needs.
Poorly designed ductwork shows itself through chronically uncomfortable rooms, excessive noise from vents, high energy bills, and equipment that can’t keep up. In older homes, you might see undersized ducts for modern equipment, too many sharp bends that restrict airflow, inadequate return air pathways, or ductwork that wasn’t properly sized for the home’s layout. Many older Pickering homes have ductwork that was adequate for original equipment but struggles with modern high-efficiency systems that move air differently.
