I use a cleaning repair team to scrub my beach condo once a week.
And they usually do a great job on their own just using the basic repair that I pay for; However, the last time they came they went above & beyond which was entirely delightful of them.
They ended up cleaning the outer air vents of my central heating, ventilation and A/C methods. The outer air vents of my central heating, ventilation and A/C methods are not something that is space of their deal plus they do not have to do it. And they went plus cleaned all my air vents of my central heating, ventilation and A/C methods at no extra cost to myself and others what so ever! They did not ask for extra pay plus did not even hint at asking for it. They did a enjoyable job plus I provided them a little extra pay on my own. The air vents to the central heating, ventilation and A/C method could use a great cleaning on the outside. Because it is the outer dirt collecting on them that ends up getting into the inner air vents plus eventually gets into the ductwork, making a huge jammed up mess that could crash my central heating, ventilation and A/C methods all together! By having the outer air vents scrubbed clean it also avoids the need for frequent ductwork cleaning. It is something I could honestly start doing on my own, however it is a matter of remembering to get up on a ladder plus undoubtedly get it done, then plus it is having the energy.
