Cold Air return filter filthy after one week

Cold air return filter super dirty after one week. So bad it makes the heat pump compressor freeze up. I know it is not the unit as I've had it checked. New dryer vent hose. Do my ducts need cleaning? This is happening on my rent house but was never a problem in the 5 years we lived there. Thanks.

It's possible the ducts need to be cleaned but there would have to be an awful lot of dust bunnies blowing out of the vent to clog the filter in one week.

You need to determine where it's coming from. Do the renters leave the doors or windows open ?
Has there been rug work done or major cleaning done ?

Thanks for the quick reply. That's what I was thinking as far as dirty ducts. No, on windows open or remodeling. It's definitely coming from some where. We ran a wood stove full on when we lived there and had no problem at all like is happening now.

I got quoted $30 per vent register to clean. Is this a fair price? They use the rotobrush system.

Prices vary by area. Everyone has deals. "Clean entire house and dryer vent is free".

I would use a reputable company. If you don't know any....ask around...... ask a friend.

I do NOT recommend a brush used in duct work especially if you have any flex duct work.

Stay away from any company that uses a Roto Brush. They just can't do a good job. Look for a company that uses negative air. An average house should take 2 guys 5-6 hours if faster than that run!! It should include cleaning blower, coil, drain pan, AHU etc etc.
