Typical quarterly maintenance in most areas runs $300-$450 per visit. A full inspection, biofilm evaluation, blower check, and effluent sampling should all be included. Annual cost should be around $1,200-$1,800. Prices vary by region – rural areas sometimes pay more due to travel. Get multiple quotes. Cheapest isn’t always best – verify they’re EPA-certified contractors.
