Heating & Cooling
Cleaner indoor air starts with the system moving it.
Indoor air quality is not one product. It starts with airflow, filtration, clean coils, dry condensate paths, duct condition, and humidity control. On Cape Cod, damp basements, seasonal homes, pollen, salt air, and older ductwork can all affect comfort.
Durfee helps homeowners choose the right filters, maintain heat pumps and mini-splits, evaluate duct cleaning, and address HVAC conditions that contribute to dust, odors, poor airflow, or humidity problems.
The filter store makes ongoing filter replacement easier, and maintenance plans keep the system clean enough to do its job.

Everyday air quality
Small habits make a real difference.
The best indoor air quality plan usually starts with the basics: the right filter, changed on schedule, and HVAC equipment that is clean enough to move air properly.
From there, homeowners can consider duct cleaning, humidity control, and equipment upgrades when the symptoms point beyond normal maintenance.

Indoor Air Quality — questions, answered.
- Yes, as long as the filter fits the system and does not restrict airflow beyond what the equipment can handle.
- Duct cleaning is most useful after renovations, when ducts have visible buildup, or when dust and airflow complaints point to the duct system.
- It can. Dirty coils, clogged drains, neglected mini-split heads, and damp ductwork can all contribute to odor issues.
