We Offer a free inspection on your ac system to help evaluate how dirty it is. A trained british engineer will come to your property at a convenient time for you. This allows you to have a conversation about the process in person. Then using an endoscopic inspection camera we will take photos of the inside of your ac unit which allows us to see what's inside. These pictures will help you decide whether to book the services and if you do the level of work needed to remove what we've found. In our experience dust builds up extremely quickly but in worse cases we find harmful mould. In these situation we endeavor to give you our soonest possible appointment.
