Question 1

What is the best duct material?

Accepted Answer

Sheet metal ducts are generally the best choice for most residential HVAC systems, offering superior durability, airflow efficiency, and longevity compared to flexible or fiberboard alternatives.

Sheet metal ducts, typically made from galvanized steel or aluminum, provide the smoothest interior surface for optimal airflow with minimal resistance. They don't sag over time like flexible ducts, maintain their shape for decades, and are less prone to damage from rodents or physical impact. Metal du

Question 2

How often should ductwork be replaced?

Accepted Answer

Ductwork typically lasts 15-25 years, but replacement timing depends more on condition than age. Well-maintained ducts in good condition can last decades, while poorly installed or damaged ductwork may need replacement much sooner.

Signs your ductwork needs replacement include visible damage like holes, disconnected joints, or crushed sections, excessive dust throughout your home despite regular cleaning, uneven heating or cooling between rooms, and significantly higher energy bills without exp

Question 3

How do I improve airflow from my vents?

Accepted Answer

Poor airflow from your vents is usually caused by dirty filters, blocked vents, or ductwork issues - most of which you can check yourself before calling a professional.

Start with the simplest solution: check your furnace filter. A clogged filter is the most common cause of reduced airflow throughout your home. If it's dirty or hasn't been changed in 2-3 months, replace it with a new one. Make sure you're using the right size and don't go higher than MERV 11 unless your system is designed for i

Question 4

How do I know if my ducts need cleaning?

Accepted Answer

Most Ottawa homes benefit from professional duct cleaning every 3-5 years, but several signs indicate your ducts may need attention sooner. If you notice excessive dust accumulating on surfaces despite regular cleaning, or if family members are experiencing increased allergy symptoms or respiratory issues, your ductwork could be circulating contaminants throughout your home.

Visible signs around your vents are often the clearest indicators. Look for dust buildup around supply and return vents,

Question 5

Should I seal my ductwork?

Accepted Answer

Yes, sealing your ductwork is one of the most cost-effective improvements you can make to your HVAC system. Most homes lose 20-30% of their heated or cooled air through leaky ducts, which directly impacts your energy bills and comfort.

Duct sealing involves identifying and closing gaps, cracks, and disconnected joints in your ductwork system. Common problem areas include connections at registers, joints between duct sections, and where ducts connect to your furnace or air handler. Professional

Question 6

What are signs of leaky ductwork?

Accepted Answer

Leaky ductwork typically shows several telltale signs that Ottawa homeowners can spot, with uneven temperatures between rooms being the most common indicator.

Temperature and airflow issues are usually the first signs you'll notice. Some rooms may feel consistently warmer or cooler than others, even with the thermostat set to the same temperature. You might also notice weak airflow from certain vents, or rooms that take much longer to reach the desired temperature. If you have to constantly adj

Question 7

Should I insulate my ductwork?

Accepted Answer

Yes, insulating your ductwork is one of the most cost-effective energy improvements you can make, especially if your ducts run through unconditioned spaces like basements, crawl spaces, or attics.

Uninsulated ducts lose significant energy - studies show that poorly insulated ductwork can waste 20-30% of your heating and cooling energy. In Ottawa's climate, where we have both hot summers and cold winters, this translates to hundreds of dollars in wasted energy costs annually. When heated air tra
