Common signs include excessive dust, lingering odours, stale or stuffy air, inconsistent humidity, condensation and noticeable airborne particles. The cause varies from home to home, so it’s worth finding the source before choosing a solution. Dust that builds up quickly or shows inside your vents is often the first clue: see when duct cleaning makes sense.
Start with the source: odours from carpets, cooking or damp areas won’t be fixed by equipment alone. After that, better filtration, balanced ventilation, humidity control, duct cleaning or air purification can help. Donaldson assesses your concerns and your existing HVAC system, then recommends what suits your home. If it feels stale or stuffy, start with HRV and ERV ventilation.
They solve different problems. Duct cleaning removes accumulated dust and debris from the ductwork itself in one visit of about 2–4 hours. A whole-home air purifier works continually, treating the air as it circulates through your HVAC system. Depending on your home, one or both may be appropriate. Compare whole-home air purifiers.
Both systems exchange stale indoor air for fresh outdoor air while recovering energy from the outgoing air. An HRV primarily transfers heat, which helps keep warmth in during colder weather, while an ERV also transfers some moisture. Which option makes sense depends on your home’s construction, HVAC system and humidity. See how HRVs and ERVs compare.
Yes. Heated indoor air can become very dry during Ontario winters, leading to static and drying wood floors and trim. A whole-home humidifier adds controlled moisture through your HVAC system, helping maintain a more comfortable humidity level throughout the home. Learn more about whole-home humidifiers.
