Furnace installed 3-14-06. No one ever came back as promised to check on it before winter and bring filters as promised. Has been working ok but thermostat was not working recently when checked by us. We called several times being told we would have to pay a $93.00 dollar fee for Sears to come and check out the problem. We knew the problem with the thermostat and didn't need any one coming to our home to tell us and having to pay 93.00 for them to do this. After talking to Sears several times and finally promised someone would come and replace the thermostat or at least bring us the filters that were promised when we had the furnace installed we still have yet to hear from anyone. We went and purchased a new thermostat because we never got a call back on the problem as promised. At least we should get the filters that were to be included with our furnace when we had it installed. By the way we were told that they(Sears) had no records of them doing their follow up check on the furnace. So at least they admitted to them not doing the follow-up as they were supposed to. We are not happy with the treatment with our purchase, and will not be advising anyone to purchase a item that needs installed or a large appliance from Sears.
