Extraction Systems Cleaning: Hood and Duct Cleaning
Kitchen extraction hood and duct cleaning is the process of removing grease that has accumulated in a commercial kitchen. Our cleaning services include areas such as inside the ducts, flues, hoods, fans, and vents of exhaust systems of commercial kitchens.
If you run a commercial kitchen, you need to get your extraction system cleaned regularly. We recommend deep cleaning at least once a year. Cleaning may be required more often if you run busy premises or depending on the type of food you cook. Watch a video about the importance of extractor hood checks.
We use a variety of specialist techniques to clean the entire commercial kitchen grease extraction system. Furthermore, we clean from the rooftop fans to the kitchen extraction hood and everywhere in between.

Our kitchen extraction system cleaning services include:

Key benefits of the regular commercial hood and duct cleaning
There are many benefits to getting regular kitchen extract duct cleaning. One important reason is that you are obliged to by law.
Kitchen Ducting Cleaning is required by law.
A Building Warrant of Fitness under the New Zealand Building Act requires a yearly inspection, clean and sanitisation of any ventilation and air conditioning system including flexible ducts and any mechanical ventilation.
Your insurance company may require commercial hood and duct cleaning.
If you don’t keep your equipment clean and your negligence can be shown as the cause of an accident, then your insurance company may not payout.
You reduce the risk of fire by ducting cleaning.
No-one wants an accident to happen at their restaurant or food premises. Removing grease build-up reduces your fire risk and fire hazards.
You reduce health and safety risks.
Regular cleaning reduces the risk of contaminated fat dripping back down to your cooking equipment or entering water supplies, which benefits the health of your customers and your staff.
You will save on costs
Keeping your commercial kitchen extraction equipment clean will save you money. Keeping your equipment in good condition reduces the risk of breakdowns such as the fan motor burning out, which is costly to repair. You will also save money because clean machines run more efficiently. Regular cleaning is also likely to be more cost-effective than having to pay a company to do a major clean and overhaul of your system which has been uncared for.
