After weeks of delay due to issues with my warranty and another contractor that took my check and deserted me, Lieber Mechanical renewed my faith in decent people!!! They went the extra mile to get my heater fixed and treated me with respect! I am forever grateful and will be using them for everything in the future. They have been the silver lining in a difficult situation. I finally slept like a baby last night in my cozy home. Thank you, thank you, thank you!
