Should I seal my ductwork?

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 duct sealing typically uses mastic sealant or metal-backed tape (never regular duct tape, which actually fails over time) to create airtight connections.

In Ottawa's climate, proper duct sealing is especially important because we rely heavily on our heating systems for 6+ months of the year. Leaky ducts in unconditioned spaces like basements, crawl spaces, or attics mean you're essentially heating or cooling those areas instead of your living space. This is particularly wasteful when ducts run through unheated basements, which is common in Ottawa homes.

Professional duct sealing typically costs $1,500-$3,000 for an average Ottawa home and can reduce energy bills by 15-20%. Many homeowners see payback within 3-5 years through lower utility bills. The work should be done by licensed HVAC technicians who can also inspect for other issues like inadequate insulation or improperly sized ductwork.

Signs you need duct sealing include uneven temperatures between rooms, high energy bills, excessive dust, or difficulty maintaining comfortable temperatures. A professional energy audit or duct inspection can identify the severity of leaks using specialized equipment.
