Should I replace my furnace filter after construction work is done in Ottawa?

Yes — replacing your furnace filter after construction work is one of the simplest and most affordable steps in the post-construction cleanup. Replace it when construction ends, and plan to replace it again a few weeks later once the post-construction cleaning is done and leftover dust has had time to work its way through the system. During an active renovation a filter can clog much faster than its normal lifespan, and a clogged filter restricts airflow, makes the furnace work harder, and stops filtering well.

Choosing the Right Filter for Post-Construction Recovery

During the post-construction period, consider temporarily upgrading from a basic fibreglass filter to a higher-rated pleated filter. Furnace filters are commonly rated on the MERV scale (Minimum Efficiency Reporting Value) — the higher the number, the finer the particles the filter is designed to catch. A basic fibreglass filter mainly catches larger particles and does little for fine construction dust, while a higher-rated pleated filter does a much better job on the fine drywall and concrete dust that causes the most trouble. Better filters cost more, but they are still an inexpensive part of the cleanup.

Don't jump to the highest-rated filter you can find without checking your system's specifications. Some residential furnaces are not designed for the extra air resistance of very high-rated filters, and the wrong filter can restrict airflow enough to strain the system. Check the owner's manual or ask your HVAC technician what rating your furnace can handle.

The filter schedule during and after construction should be more frequent than normal. During active construction, check the filter every week and replace it when it looks grey or clogged — that may mean frequent changes during dusty phases like drywall sanding or demolition. After construction ends and the post-construction clean is done, replace the filter once more and keep checking it regularly for the next few weeks, since dust trapped in ductwork and on surfaces can keep getting stirred up after the work stops. Once the filter stays clean between checks, you can go back to your usual schedule.

Replacing the filter is a quick job most homeowners can do themselves, but it is only one part of the HVAC equation after construction. The filter catches particles passing through it, but construction dust that has already settled inside the ductwork, on the blower fan, and on the evaporator coil can keep getting blown around every time the system runs. HVAC duct cleaning addresses the dust that the filter cannot reach; quotes in Ottawa can run roughly $400 to $800 depending on the size of the system, so ask for itemized written quotes. A fresh, suitable filter together with duct cleaning where needed is a sensible way to get your HVAC system and indoor air back on track after renovation work.
