Typically we suggest a homeâs air ducts be cleaned every five to eight years. Homeowners with children, pets, respiratory issues or a compromised immune system may want to get their HVAC duct system cleaned more often. The better filtration the system has cuts down on cleaning frequency.
HOW OFTEN SHOULD YOU HAVE A HOOD CLEANING? The most common hood cleaning frequency is every 3 months. This can vary, however. The commercial kitchen/restaurant exhaust systems that needs cleaning most often are those over wood-burning or charcoal-burning stoves. These should be cleaned every month at least, and in some cases as often as every 2 weeks. Below are various types of cooking establishments and their most commonly recommended hood cleaning frequencies. Wood-burning or charcoal-burning stoves, charbroilers, 24-hour restaurants, and some hamburger places: EVERY 30 DAYS.
