Sears installed a Kenmore central a/c unit few years ago and the unit has been under a master protection agreement since then, had a problem with unit not working properly and called Sears, tech came and said that the thermostat needs to be replaced and he wants $350.00 to replace a $40 unit that takes less than 2 minutes to replace it. What a rip off. I have been using Sears service for several years and on multiple rental properties and the thermostats have been replaced on other units by Sears without a charge. Over the last two years Sears service has completely deteriorated, their front line staff is totally incompetent, neither do they understand the problem nor can they provide proper service, and most of all the technicians try to charge you even when the come out for regular maintenance service. This has happened twice when they came out to do annual service they tried to bill me. It appears that it is not worth buying any kind of service from Sears anymore because apparently the protection agreement is not what it is meant to be, it appears that this is a way for Sears to find ways to charge exorbitant amounts of money for no reason. If Sears cannot provide the service it used to, I for one will be cancelling my protection agreement as there are plenty of other warranty companies out there and needless to say I will stay away from anymore Sears products becuase it honestly is a nightmare to deal with the incompetent service that Sears provide.
