I am thinking of starting a new way of business here in Lebanon , giving homeowners maintenance contract for their A/C's usually mini-split units for a sum of money they will pay yearly, i'll maintaine their ac's without any charge .
I just want to know if this idea is applicated anywere and how it works , it's disandages and advantages ?
Are the spare parts and the ***** included in the contract ?
or just only the servicing , like filters and coils cleanings and regular chek ups.?
