    This post reverses a previous complaint. I spoke with Fahy's billing department and they…read morestraightened it all out!

    READ BEFORE YOU CALL THEM:…read more My father (who speaks very little English) had bought a house and had called this company 2 days ago to come in to see why the heat was not working. Fahy MJ & Sons Inc had sent in their service tech in to check out the issue. The tech came in at 10-11 am talked on the phone the whole time, looked the furnace up and down installed two thermostats without permission and left almost close to 5 PM. The heat was never fixed. The company charged my dad 580 dollars for spending over 5 hours just diagnosing the issue. The heat was never fixed. When i called to complain today as to why my father was charged that much even though they did not fix the heat. The rude lady that answered the phone told me that the tech was only diagnosing the issue. She admitted that "the furnace did work when the tech left and that they STILL do not know whats wrong and they will need to come back again to diagnose further". She said " This is what we do and these are our business policies" What angered me the most is that instead of being a professional and discussing facts and logic she started to berate my father. No one should be exposed to that kind of treatment from anyone; much less from an employee of a legitimate business. I called her out on her business practices that they follow. They go for a service call spent an indeterminate amount of time "diagnosing" the problem and then bill you and tell you that they "Need To come back to do more diagnosing" I asked her if they had provided my dad with an estimate of the job and she said no. Instead the tech spends all of his work day in my fathers house while on the phone talking and very little working; because Fahy MJ cannot hire qualified techs that know how to do their jobs. This sub-par level of expertise and customer service is what makes consumers like us fear the day that our heat source breaks down. After talking on the phone to this very rude and unprofessional woman she became very irate and belligerent and started to say things like " Are you threatening me?, I am going to call the cops because i feel threatened". The woman i spoke to gives the company a bad name. If she is the manager of that office then the business will continue to experience complaints from consumers like me. Very shameful that a reputable company would do this to my father. They took advantage of my father's inability to speak English. Very sad to have to write this. DO NOT DO BUSINESS WITH THEM.
