Most basic drain cleaning services range from $150-$300. Complex repairs involving re-piping or water damage restoration can cost more. We provide upfront pricing before any work begins.
How often should I have my AC drain line cleaned?
In Moreno Valley’s climate, we recommend professional cleaning every 12-18 months. Homes with severe hard water issues may need service every 6-12 months.
