If the indoor A/C coil (the evaporator coil) gets clogged while your furnace is running, it can block the airflow moving through your system. This can cause:
Weak air coming out of your vents
Musty or stale smells
Uneven temperatures with hot and cold spots around your home
When airflow is restricted, your furnace has to work much harder to push air through. That means higher energy bills and a greater risk of your furnace overheating.
At J&J Pro Services, we make sure your system stays clean and running efficiently so your home stays comfortable and your equipment is protected.
