You will find that a lot of the companies selling and renting stair lifts will also provide servicing for them, with them being a specialised product and knowing that customers are dependant on the stair lifts to be able to move about within their own home they will understand the importance of not only getting a stair lift fixed for you but also ensuring the safety of the lift and the proper running of it so that you get the best possible use from the one that you own or rent from them.
You can often buy an extended warranty with your stair lift that could be for an additional year or more.
There can also be a call out service offered which can cover 24 hours a day, as understandably no one can predict when their stair lift may suddenly malfunction.
Qualified engineers can also carry out regular servicing, possibly each 6 months or yearly to make sure that the stair lift runs as well as it should do and they can order and replace parts that may need replacing and make sure that it is running as it should and is safe for you to use too.
Because stair lifts are a product with mechanical moving parts and electronics it is a good idea that they are serviced, for your safety and the safety of carers even, and to get an optimum level of use from them, just like a car needs servicing at least yearly with all of the moving parts involved and to get the most efficient use from it, so does a stair lift need and benefit from being regularly serviced.
